Florida's residential electricity rate is 15.2¢/kWh and natural gas runs $22.65/Mcf. Cost-of-living index for Florida is 104 (US = 100). Gasoline runs about $3.86/gal at retail. Florida's dominant generation mix is natural gas (72%) + solar (8%) (EIA EPM, Mar 2026). Grid carbon intensity is 0.836 lbs CO₂/kWh (EPA eGRID 2023). Residential rates are trending up year-over-year per EIA EPM Table 5.6.A. Florida's full-retail net metering policy is the subject of ongoing legislative debate; utilities have proposed transitioning to avoided-cost compensation similar to CA's NEM 3.0.

Florida Financial Snapshot (2026) — EV Charging Cost Calculator

How the EV Charging Cost Calculator Math Works Under Florida Law

The EV Charging Cost Calculator runs a well-known formula (principal × rate, discounted cash flow, amortization, or equivalent) client-side and layers on Florida's tax and cost-of-living inputs. State-specific numbers — brackets, exemptions, and averages — come from public federal / state datasets cited in the sources section.

Local context: Florida

Housing economics in Florida. The median home value runs 10.3% above the U.S. baseline for Florida is $395,000 per Zillow's home-value index. Effective property tax sits at 0.89% of assessed value, below the 0.99% national average tracked by the Tax Foundation. Lenders in Florida have quoted 6.30% on the 30-year fixed product over the trailing four-week window per Freddie Mac PMMS — the prevailing posted rate before any borrower-specific lock-ins.

Income and tax climate. Median household income in Florida reaches $75,630 per the ACS five-year vintage, trailing the $78,538 U.S. median. Florida's top marginal state income tax bracket lands at 0.00% — one of nine states that levies no broad-based income tax, shifting the revenue burden onto sales, property, and severance levies. BEA's Regional Price Parity scores Florida at 103.6 (national = 100), meaning a dollar in Florida buys 97¢ of national purchasing power.

Florida versus the U.S. baseline

How does Florida stack up against the national average on the metrics that drive the calculators on this page? The table below pairs the Florida-specific reading against the U.S. baseline so you can see at a glance whether your local scenario runs above or below typical. Three to five percentage points of difference on most of these inputs translates into meaningful changes in calculator output — for example, a 50-basis-point difference in mortgage rate moves the monthly payment on a $400,000 30-year loan by roughly $130.

How to use the EV Charging Cost Calculator

Walk through using the EV Charging Cost Calculator with Florida-specific defaults pre-loaded from primary sources.

  1. Pre-fill with local dataEach calculator on this page loads with state- or city-specific defaults pulled live from primary sources (FRED, BLS, Zillow, Freddie Mac PMMS, IRS, BEA). The blue values shown next to each input are the local averages so you can see how your scenario compares to the typical case before changing anything.
  2. Override the inputs you controlChange any field to model your actual situation. The math reruns in your browser the moment you change a value — no signup, no API call, no data transmission. Hover over the small (i) icon next to each label to see the formula that field feeds and where the default came from.
  3. Read the derived valuesThe result panel shows the primary calculation (monthly payment, take-home pay, savings projection, etc.) plus the intermediate values that drive it. Each line item is labeled with the formula component it represents so you can verify the arithmetic against any agency publication, textbook, or competing calculator.
  4. Adjust assumptions and re-runMost calculators have a section for assumption inputs that are easy to overlook — annual raises, expected return, inflation, vacancy rate, depreciation schedule, marginal vs. effective tax treatment. The defaults are conservative; aggressive scenarios usually require explicit overrides.
  5. Save to "My Numbers"When the inputs match your reality, click Save to "My Numbers". The values persist to your device's local storage (IndexedDB) and reload automatically on your next visit. Nothing is transmitted to any CalcFi server — the saved-state feature is deliberately client-side only for privacy.
  6. Compare scenarios side by sideMost calculators offer a comparison view that shows two or more scenarios side by side. Use this to model decision points: 15-year vs 30-year mortgage, Roth vs Traditional IRA, salary vs hourly, lease vs buy. The comparison view also produces a shareable summary you can download as PNG or PDF.

Florida Financial Planning Tips

Tip

Track take-home pay: no state income tax means only federal + FICA apply — one of the simpler payroll pictures in the U.S. in Florida.

Tip

Anchor savings goals to the Florida cost of living index (103.6). A national 20% savings rate needs adjustment up or down depending on local expense floors.

Tip

Use tax-advantaged accounts first: 401(k), HSA, IRA. Since Florida has no income tax, Roth accounts may be especially attractive — you lock in today's zero-state-tax cost forever.

Frequently Asked Questions: EV Charging Cost Calculator in Florida

How does the ev charging cost work in Florida?
The ev charging cost calculator runs the standard client-side formula and layers on Florida's zero state income tax, 0.89% property tax rate, and cost-of-living index of 103.6. All inputs stay in your browser.
What's the average residential electricity rate in Florida?
Florida's residential electricity rate is 15.2¢/kWh — 2.2¢ above the national average of 13¢/kWh (US avg, EIA EPM Table 5.6.A, Mar 2026). This rate directly drives the running cost of any electric appliance, heat pump, or EV charged at home.
How fast does a heat pump pay back in Florida?
At 15.2¢/kWh in Florida, a heat pump runs ~$1,600/yr in electricity. Savings vs your current fuel depend on your heating load; use the calculator for a personalized estimate. Educational reference only.
What's the cost to fully charge an EV in Florida?
At Florida's 15.2¢/kWh residential rate, charging a 66 kWh battery (~300-mile range) costs ~$10.06. That's ~$3.81/100 miles in "fuel." Based on EPA avg 25 kWh/100 mi for mid-size EVs. Educational reference only.
How does Florida's utility regulatory model affect energy costs?
Florida operates under a investor-owned utility (IOU). The state's net metering policy is full retail-rate net metering. Florida's full-retail net metering policy is the subject of ongoing legislative debate; utilities have proposed transitioning to avoided-cost compensation similar to CA's NEM 3.0.
Does Florida have state income tax?
No. Florida is one of seven states with no state income tax. Residents pay only federal income tax on wages and salaries.
What is Florida's homestead exemption?
Florida's homestead exemption reduces your property tax assessed value by up to $50,000 for your primary residence. The Save Our Homes provision also caps annual assessment increases at 3%.
Why is Florida homeowners insurance so expensive?
Hurricane risk is the primary driver. Florida accounts for a disproportionate share of national hurricane losses, and insurer exits from the state have reduced competition, pushing premiums up.
Is flood insurance required in Florida?
It's required if you have a federally backed mortgage and your property is in a FEMA-designated flood zone. Even outside designated zones, 25% of flood claims come from non-flood-zone properties — it's strongly recommended statewide.

How we compute this — methodology

CalcFi pSEO pages combine three inputs: (1) the calculator formula itself, which runs client-side so no inputs leave your browser; (2) state-level financial constants from primary public datasets; and (3) national benchmarks for comparison. The Florida page uses the property tax rate (0.89%), median home price ($395,000), and no state income tax from the sources listed below.

Refresh cadence:state tax brackets and minimum wage rates are reviewed annually after each state's legislative session. Property tax, median home price, insurance, and cost-of-living figures are reviewed annually against the primary sources. Income percentiles are refreshed when the Census CPS/IPUMS releases update (typically September). Page-level dateModified matches the last editorial review date, shown above.

Known limits: statewide averages mask large intra-state variance — county-level property tax and metro-level home prices differ significantly from the figures shown. For the most precise calculations, cross-check the output against your actual county assessor and the latest federal/state tax tables at filing time.

Real-world example: Ohio homeowner calculating solar payback▾

A Columbus homeowner installs a 7kW rooftop solar system at $21,000 gross cost. Ohio average electricity rate: $0.13/kWh. Federal ITC credit (30%): $6,300.

  • System size: 7 kW
  • Gross system cost: $21,000
  • Federal ITC (30%): $6,300
  • Net cost: $14,700
  • Annual production (Ohio avg): ~7,700 kWh
  • Rate: $0.13/kWh
  • Annual savings: ~$1,001
Simple payback period
~14.7 years

Takeaway: Ohio payback is longer than Arizona (~8 years) due to fewer peak sun hours (4.5 vs 6.5). Net metering policy matters — if Ohio caps export credits, savings shrink. The federal ITC is the single biggest lever; state credits vary widely.

When this calculator is wrong▾
  • Peak sun hours vary significantly by geography

    Solar production calculations depend on local irradiance. Arizona averages 6.5 peak sun hours/day; Ohio averages 4.5; Seattle 3.5. A system sized for Arizona produces 44% more power than the identical system in Seattle. Production estimates built on national averages will be wrong for your location.

  • Net metering policies change — check your utility

    Net metering crediting structures have been reduced or eliminated in several states (California's NEM 3.0 in 2023 cut export credits by ~75%). ROI calculations built on pre-policy-change net metering rates overstate savings for new installations in affected states.

  • Federal ITC requires sufficient tax liability

    The 30% federal investment tax credit reduces your tax liability — it is a credit, not a refund. If your total federal tax owed is $3,000 and the ITC credit is $6,300, you use $3,000 this year and carry forward $3,300. Carry-forward is allowed, but low-income households may not fully capture the credit.

  • Battery storage payback is longer than solar-only

    Adding a home battery (Tesla Powerwall ~$12,000 installed) extends payback periods by 5-8 years unless your utility has demand charges or time-of-use pricing that rewards peak-shifting. In most residential flat-rate markets, battery economics are currently marginal.

Key Takeaways

  • Home EV charging costs $0.03-$0.06 per mile vs $0.10-$0.18 per mile for gasoline, saving the average driver $800-$1,500 per year in fuel costs
  • A full charge on a 75 kWh battery costs $8-$12 at home ($0.12-$0.16/kWh) but $25-$45 at a DC fast charger ($0.30-$0.60/kWh)
  • Time-of-use (TOU) electricity rates can reduce home charging costs by 30-50% -- charging at midnight instead of 6 PM saves $300-$500 annually
  • Level 2 home charging (240V) costs $500-$2,000 to install but saves $200-$400/year vs public charging, paying for itself in 2-5 years
  • Charger efficiency matters: Level 1 loses ~15% to heat, Level 2 loses ~10%, DC fast charging loses ~7% -- you pay for kWh drawn from the grid, not just kWh entering the battery

Understanding EV Charging Levels and Costs

EV charging comes in three levels, each with dramatically different speeds, costs, and use cases:

Level 1 (120V Standard Outlet): Every EV comes with a Level 1 charging cable that plugs into a standard household outlet. It delivers approximately 1.2-1.4 kW, adding 3-5 miles of range per hour. A full charge on a 75 kWh battery takes 50-60 hours.

Level 1 is free to install (you already have outlets) but painfully slow. It works for plug-in hybrids (small batteries, 8-15 kWh) and for EV owners who drive less than 30-40 miles daily. The electricity cost is identical to Level 2 (same rate per kWh), but the 15% charger efficiency loss means you pay slightly more per mile than Level 2.

Level 2 (240V Dedicated Circuit): The standard for home EV charging. A 240V circuit (like a dryer outlet) with a dedicated EVSE (Electric Vehicle Supply Equipment) delivers 6-19 kW, adding 20-60 miles of range per hour. Most EV owners charge overnight in 4-8 hours.

Installation cost ranges from $500 (if a 240V outlet is nearby) to $2,000+ (if new wiring and panel work are needed). The EVSE unit itself costs $300-$700 for a quality unit (ChargePoint, JuiceBox, Grizzl-E). Level 2 charging efficiency is approximately 90%, meaning 10% of electricity drawn is lost to heat in the charger and onboard converter.

Level 3 / DC Fast Charging (DCFC): Commercial charging stations delivering 50-350 kW. These add 100-200+ miles in 20-40 minutes. Tesla Superchargers, Electrify America, and ChargePoint all operate DCFC networks.

DCFC costs $0.30-$0.60 per kWh, roughly 2-4x the cost of home charging. Some networks charge by the minute instead of by kWh, which penalizes slower-charging vehicles. DCFC is essential for road trips but should not be your primary charging method -- it is 3-4x more expensive than home charging and frequent DCFC use can accelerate battery degradation.

The Real Cost Per Mile: EV vs Gasoline

The per-mile fuel cost comparison strongly favors EVs in virtually every scenario:

Electric Vehicle (at home charging):
Average EV efficiency: 3.0-4.0 miles per kWh
Average electricity rate: $0.14/kWh
Charger efficiency: 90% (Level 2)
Cost per mile: $0.14 / (3.5 mi/kWh x 0.90) = $0.044/mile

Gasoline Vehicle:
Average fuel economy: 25-30 MPG
Average gas price: $3.50/gallon
Cost per mile: $3.50 / 27.5 = $0.127/mile

The EV costs 65% less per mile in fuel. For a driver covering 12,000 miles per year:

EV annual fuel cost: 12,000 x $0.044 = $528
Gas annual fuel cost: 12,000 x $0.127 = $1,524
Annual savings: $996

In high-electricity-cost areas (California at $0.25/kWh), the EV cost per mile rises to $0.079, but the savings are still $576/year. In low-cost areas (Pacific Northwest at $0.08/kWh), EV cost drops to $0.025/mile, saving $1,224/year.

Only in the most extreme scenario -- very cheap gas ($2.50/gal), expensive electricity ($0.30/kWh), and an inefficient EV (2.5 mi/kWh) -- does the gas car approach EV fuel costs. Even then, the EV is slightly cheaper.

Time-of-Use Rates: The Smart Charger's Secret Weapon

Many utilities offer time-of-use (TOU) rate plans where electricity costs less during off-peak hours (typically 9 PM to 6 AM). Some utilities offer dedicated EV rates with even deeper off-peak discounts:

Standard rate: $0.14/kWh (all hours)
TOU peak (2 PM - 9 PM): $0.25/kWh
TOU off-peak (9 PM - 6 AM): $0.08/kWh
EV-specific rate (midnight - 6 AM): $0.05/kWh

The difference between charging at peak ($0.25) and off-peak ($0.08) is enormous:

Annual charging at peak: 12,000 mi / 3.5 mi/kWh / 0.9 eff = 3,810 kWh x $0.25 = $952
Annual charging at off-peak: 3,810 kWh x $0.08 = $305
Savings from TOU: $647/year

Most EVs and smart EVSEs support scheduled charging. Set your car or charger to begin charging at the off-peak time and your savings happen automatically. Some utilities require a separate meter for EV charging to qualify for the EV rate -- the $200-$400 meter installation cost pays for itself in the first year.

For a comprehensive view of how EV ownership affects your household finances, including charging costs, consider running the numbers through our EV vs gas comparison calculator for a complete total cost of ownership analysis.

Home Charging Installation: What It Actually Costs

The total cost of Level 2 home charging installation depends on your existing electrical setup:

Best Case ($500-$800): Your electrical panel has spare capacity (at least 40A available), and the panel is near your garage. An electrician runs a 240V/50A circuit to the garage and installs a NEMA 14-50 outlet or hardwires your EVSE. Add $300-$500 for the EVSE unit. Total: $800-$1,300.

Moderate Case ($1,000-$2,000): The panel is on the opposite side of the house from the garage. The electrician runs wire through attic or crawl space (50-100 feet). The panel has spare capacity but needs a new breaker. Total with EVSE: $1,300-$2,500.

Worst Case ($2,000-$5,000): The electrical panel is full or undersized (100A or less). You need a panel upgrade to 200A ($1,500-$3,000) before adding the EV circuit. Or you live in a condo/apartment where running a dedicated circuit is complicated by shared spaces. Total with EVSE: $3,500-$7,000.

The IRA provides a 30% tax credit (up to $1,000) for home EV charger installation (through 2032), which reduces the effective cost significantly. Some states and utilities offer additional rebates of $200-$500.

Solar + EV: The Ultimate Savings Combination

Home solar panels generate electricity at an effective cost of $0.03-$0.07/kWh over their 25-year lifespan (after the 30% federal solar tax credit). Charging your EV with solar electricity drops your per-mile fuel cost to $0.01-$0.02 -- essentially free driving.

A typical EV needs approximately 3,500-4,000 kWh per year for charging. A 2-3 kW solar array addition (6-8 panels) generates this amount in most US locations. The additional solar panels cost $4,000-$7,000 before the 30% tax credit ($2,800-$4,900 net).

At $1,000/year in charging savings, the solar addition pays for itself in 3-5 years and then provides free fuel for the remaining 20+ years. This is the most compelling financial case for combining solar and EV ownership.

For homeowners already considering solar, oversizing the system by 3 kW to cover EV charging is almost always the right financial decision. The incremental cost is modest and the return is high.

Public Charging Economics: When It Makes Sense

Public charging is significantly more expensive than home charging but necessary in certain situations:

Road Trips: DCFC is essential for long-distance travel. Budget $0.40-$0.60/kWh at Electrify America, $0.30-$0.50 at Tesla Superchargers, and variable rates at other networks. A cross-country trip might cost $80-$150 in charging vs $150-$250 in gas for an equivalent ICE car -- still cheaper.

Apartment/Condo Dwellers: Without home charging, public Level 2 and DCFC become primary charging methods. Costs are 2-4x home charging but still cheaper than gas. Look for free Level 2 charging at workplaces, grocery stores, and shopping centers -- many businesses offer free charging as an amenity.

Workplace Charging: Some employers provide free or subsidized workplace charging. Free workplace Level 2 charging saves $500-$1,000/year and charges your car during hours when you are not using it anyway. This is the best-case scenario for EV economics.

The worst economic scenario for an EV is relying exclusively on DC fast charging at premium rates. At $0.50/kWh, the per-mile cost rises to $0.16 -- comparable to a fuel-efficient gas car. If you cannot charge at home or work, carefully evaluate whether an EV makes financial sense.

Key Takeaways

  • Real-world EV range is typically 15-30% less than EPA ratings due to temperature, speed, terrain, HVAC use, and driving style
  • Cold weather is the biggest range killer: at 20F, expect 30-40% range reduction from battery chemistry slowdown and cabin heating demand
  • Charging to 80% instead of 100% daily extends battery life by 2-3x and only costs 20% of range -- the top 20% of charge is both slowest to fill and hardest on the battery
  • DC fast charging daily degrades batteries 30-50% faster than Level 2 home charging over the vehicle's lifetime due to heat stress
  • Modern EV batteries retain 90%+ capacity after 100,000 miles with good charging habits, making battery replacement a rare concern for most owners

Why EPA Range Ratings Are Optimistic

The EPA tests EV range under controlled laboratory conditions: moderate temperature (77F), moderate speed (48 mph average), no hills, and minimal HVAC use. Real-world driving deviates from these conditions, reducing actual range:

Temperature: Battery chemistry is temperature-sensitive. At 77F (ideal), a battery delivers 100% of rated capacity. At 40F, capacity drops to 80-85%. At 20F, capacity drops to 60-70%. At 0F, expect 50-60% of rated range. This reduction comes from two sources: the battery's internal resistance increases (less energy available) and the cabin heater draws 3-5 kW (equivalent to losing 1-2 miles of range per minute of heating).

Heat pump HVAC systems (standard on most new EVs) reduce cold-weather range loss by 30-40% compared to resistive heaters. If you live in a cold climate, a heat pump-equipped EV is essential.

Speed: Aerodynamic drag increases with the square of velocity. At 80 mph, an EV uses approximately 40% more energy per mile than at 60 mph. Highway driving at American interstate speeds (70-80 mph) can reduce range by 20-30% compared to EPA ratings, which use a lower average speed.

Terrain: Hills cost energy. Climbing a mountain might use 50-100% more energy than flat driving. Regenerative braking recovers some energy on descents but typically recaptures only 50-70% of the energy spent climbing. Net effect: hilly terrain reduces range 10-20% vs flat terrain.

Payload and Accessories: A fully loaded car (passengers, cargo, roof rack) weighs more and has more aerodynamic drag. A roof rack alone can reduce range by 5-10% at highway speeds. Running the AC in summer costs less range than heating in winter (AC draws 1-2 kW vs 3-5 kW for heat) but still reduces range by 5-10%.

Charging Best Practices for Battery Longevity

Lithium-ion batteries degrade over time and use, but the rate of degradation is heavily influenced by how you charge:

Daily Charge Limit: 80%
Keeping the battery between 20% and 80% state of charge minimizes stress on the battery cells. The last 20% of charge (80-100%) applies higher voltage that accelerates electrode degradation. Charging to 80% daily instead of 100% can extend battery life by 2-3x according to degradation models.

Most EV owners set their daily charge limit to 80% and only charge to 100% before long trips. This costs minimal range (typically 40-60 miles of the total) while significantly extending battery life.

Avoid Deep Discharges:
Running the battery below 10% regularly causes similar stress as charging to 100%. Try to plug in before dropping below 20%. The optimal daily operating range is 20-80%, using 60% of total capacity.

Minimize DC Fast Charging:
DCFC pushes enormous power into the battery quickly, generating heat. Battery heat accelerates chemical degradation. A battery that is exclusively DC fast charged degrades 30-50% faster than one charged exclusively at Level 2 over the same mileage.

This does not mean you should never DC fast charge -- it means consider not use it daily. For road trips and occasional top-ups, DCFC is fine. For daily charging, Level 2 at home is both cheaper and healthier for the battery.

Precondition Before Fast Charging:
Most modern EVs can precondition the battery (warm or cool it to optimal temperature) before arriving at a fast charger. This allows the battery to accept charge at maximum speed and minimizes thermal stress. Always use the vehicle's trip planner or navigation to trigger preconditioning.

Understanding Charging Efficiency Losses

Not all electricity drawn from the grid reaches your battery. Several conversion steps each consume a small percentage:

Grid to EVSE (charger): 1-3% loss in the charger's power electronics
EVSE to onboard charger: 2-5% loss in cable resistance and onboard AC-DC conversion
Onboard charger to battery: 3-8% loss depending on battery temperature and state of charge
Total wall-to-battery efficiency: 85-93%

Level 1 charging has the lowest efficiency (approximately 85%) because the low-power conversion operates less efficiently. Level 2 achieves approximately 90% efficiency. DC fast charging bypasses the onboard charger, achieving approximately 93% efficiency at the charger, though the battery's own thermal management may consume additional energy.

Our calculator accounts for these efficiency losses when computing charging cost. The kWh drawn from your meter will always exceed the kWh stored in the battery. For a 52.5 kWh charge (75 kWh battery, 20% to 90%), you may draw approximately 58 kWh from the grid at Level 2 efficiency.

Battery Degradation: What to Expect Over Time

Modern EV batteries (2020+) are remarkably durable. Aggregate data from hundreds of thousands of vehicles shows:

After 50,000 miles: 95-97% original capacity
After 100,000 miles: 90-94% original capacity
After 150,000 miles: 85-90% original capacity
After 200,000 miles: 80-87% original capacity

At 80% capacity, a 300-mile EV still delivers 240 miles -- more than adequate for daily driving. Most automakers warrant the battery to 70-80% capacity for 8 years/100,000 miles. Tesla's data shows most vehicles retain 90%+ capacity at 200,000 miles with normal charging habits.

Degradation accelerates with heat (frequent DCFC, hot climates without battery thermal management), deep discharge/full charge cycling, and time (batteries slowly degrade even when not used). The controllable factors -- charging habits -- account for about 50% of degradation rate. Following the 20-80% charging practice and minimizing DCFC can meaningfully extend your battery's useful life.

For a full comparison of EV ownership economics including fuel savings, maintenance, and depreciation, use our EV vs gas total cost of ownership calculator.

For a typical 75 kWh battery at $0.14/kWh, a full charge (10% to 90%) costs about $9-$12 at home. This provides approximately 200-250 miles of range -- equivalent to about $1.50-$2.00 per gallon of gas in terms of cost per mile.

Home charging is almost always cheapest at $0.08-$0.20/kWh. Public Level 2 chargers cost $0.20-$0.35/kWh. DC fast chargers cost $0.30-$0.60/kWh. Off-peak home rates can be as low as $0.05-$0.10/kWh with time-of-use plans.

Level 1 (120V): 24-60 hours for a full charge. Level 2 (240V): 6-10 hours. DC Fast Charging: 20-60 minutes to 80%. Most EV owners charge overnight at home on Level 2 -- plug in when you get home, wake up to a full battery.

Many utilities offer lower electricity rates during off-peak hours (typically 9 PM to 6 AM). Scheduling EV charging during these hours can cut charging costs by 30-50%. Most EVs and smart chargers support scheduled charging to take advantage of off-peak rates automatically.

The cost is proportional to kWh delivered, but the last 20% (80-100%) charges slower and generates more heat. More importantly, regularly charging to 100% degrades the battery faster. Most experts recommend charging to 80% for daily use and 100% only before long trips.

At typical home electricity rates, EVs cost $0.03-$0.06 per mile vs $0.10-$0.18 per mile for gas cars. EVs are 2-4x cheaper per mile in fuel costs. Even at expensive public fast chargers, EVs are roughly comparable to gas cars in per-mile cost.

The average driver covering 12,000 miles/year saves $800-$1,500 annually in fuel costs by switching from gas to electric. With time-of-use charging and/or solar panels, savings can exceed $1,500/year. Total savings including lower maintenance costs are typically $1,500-$2,500/year.

Charger efficiency measures how much of the electricity drawn from the grid actually reaches your battery. Level 1 is ~85% efficient, Level 2 ~90%, DC fast ~93%. The lost electricity converts to heat. You pay for all kWh drawn, so a 90% efficient charge of 50 kWh actually draws ~55.6 kWh from the grid.

kWh Needed = Battery Size x (Target% - Current%) / 100

Charge Cost = kWh Needed / Charger Efficiency x Electricity Rate

Cost/Mile = (1 / mi/kWh) x Rate / Efficiency

Charger efficiency: Level 1 ~85%, Level 2 ~90%, Level 3 ~93%.
