Retirement Planning Calculators for Connecticut Residents

Retirement planning is the longest-horizon financial decision most households make. Small changes to savings rate, account choice, and withdrawal strategy compound to six-figure differences over a 40-year career.

The 4% rule and its critics

The Bengen 4% rule says a retiree can safely withdraw 4% of starting portfolio value annually (inflation-adjusted) with a 95%+ success rate over 30 years. Recent research (Morningstar, Kitces) suggests 3.3–3.7% is safer in low-yield environments. Use the FIRE Number Calculator to derive your target.

Account hierarchy — fill in this order

1. 401k up to employer match (free money)
2. HSA if eligible (triple-tax-advantaged)
3. Roth IRA if under income limits ($150k single MAGI phase-out start in 2026)
4. Back to 401k up to IRS limit ($23,500 in 2026 for under-50)
5. Mega-backdoor Roth (if plan allows after-tax + in-service rollover)
6. Taxable brokerage

Social Security timing

Claim ages 62–70. Each year delayed past full retirement age (67 for those born 1960+) boosts benefit ~8% via delayed-retirement credits. The Social Security Optimizer computes life-expectancy-weighted claim strategy using SSA actuarial tables^[1].

RMDs starting age 73 (75 in 2033)

SECURE 2.0 pushed the required minimum distribution age to 73 and to 75 starting 2033. Roth 401k RMDs eliminated starting 2026. Use RMD Calculator to project annual forced withdrawals.

Contribution limits for 2026

• 401(k) / 403(b) / TSP: $23,500 + $7,500 catch-up at 50+
• IRA / Roth IRA: $7,000 + $1,000 catch-up at 50+
• HSA: $4,300 self / $8,550 family
• SEP-IRA: 25% of compensation up to $70,000

The single most consequential retirement question: Roth or traditional? The math is simpler than advisors often present.

The core identity

If your contribution-year marginal rate equals your withdrawal-year rate, Roth and traditional produce identical after-tax wealth. Roth wins when your withdrawal rate > contribution rate. Traditional wins when withdrawal rate < contribution rate.

When Roth wins

• Early-career low-bracket years (student, first job at 12–22% bracket)
• Gap year / sabbatical (zero income)
• You expect tax rates to rise (TCJA sunset in 2027 fits this)
• You want estate-planning flexibility (Roth has no RMDs for original owner)

When Traditional wins

• Peak-earning years in 32–37% federal bracket
• High-tax state now, plan to retire in no-tax state
• Need current-year deduction to lower AGI into eligibility for other benefits (premium tax credits, Roth eligibility)

The Both approach

Most retirees benefit from tax diversification across traditional, Roth, and taxable accounts to flexibly manage withdrawal-year brackets. See Roth vs Traditional IRA Calculator.

FIRE (Financial Independence, Retire Early) comes in four flavors. Each requires a different calculator and savings rate.

Coast FIRE

You've saved enough that compound growth alone reaches your retirement number at traditional age — no more contributions needed. Typical target: 25–40% of Fat FIRE number by age 35. Use Coast FIRE Calculator.

Barista FIRE

You've saved enough to cover most expenses from portfolio withdrawals, supplemented by part-time work (often for health insurance). Typical target: 50–70% of Fat FIRE number.

Lean FIRE

Full retirement at lower-than-average spending ($40–50k/yr for a couple). Typical target: $1.0–1.25M portfolio using 4% rule.

Fat FIRE

Full retirement at higher-than-average spending ($100k+/yr). Typical target: $2.5–5M portfolio.

The FIRE Number Calculator handles all four. Adjust safe-withdrawal rate input (2.5–4%) and target expenses.

Social Security is the most undertaught wealth-preserving decision most retirees make. The claim age choice affects lifetime benefits by $200k+ for typical earners.

The claim-age lever

Monthly benefit at age 62 (early) is 30% lower than the primary insurance amount (PIA). Claiming at 67 (full retirement age for those born 1960+) pays 100% of PIA. Claiming at 70 pays 124% of PIA (8%/year delayed-retirement credits). Past 70, no further increase.

Break-even math

Claiming at 70 vs 62 requires living to about age 80–82 to break even on total lifetime benefits. SSA actuarial tables^[1] show median life expectancy for a 62-year-old male is 82, female 85. Statistically, delaying pays off for most healthy individuals.

Spousal and survivor benefits

Spousal benefit is 50% of higher earner's PIA (if higher earner claimed). Survivor benefit is 100% of deceased spouse's benefit at time of death. Delaying the higher earner's claim maximizes survivor benefit for the longer-lived spouse.

Taxation of benefits

Up to 85% of SS benefits are taxable federally if combined income exceeds thresholds ($25k single / $32k MFJ). 13 states tax some portion; 37 do not. Florida, Texas, and other no-income-tax states are SS-friendly.

CalcFi's 12 retirement calculators solve distinct questions:

• Am I on track? → Retirement Savings
• How much to contribute? → 401(k) Contribution
• Roth or Traditional? → Roth vs Traditional
• What's my FI number? → FIRE Number
• Can I Coast? → Coast FIRE
• When to claim SS? → Social Security Optimizer
• RMD for the year? → RMD Calculator
• Early withdrawal penalty? → Early Retirement Withdrawal
• Backdoor Roth? → Backdoor Roth

Three strategies for early retirees to access pre-59.5 retirement funds without the 10% penalty:

Roth conversion ladder

Convert traditional 401k/IRA funds to Roth each year of early retirement; wait 5 years; withdraw converted principal penalty-free. Requires 5-year runway of taxable savings to bridge.

SEPP / 72(t) distributions

Substantially Equal Periodic Payments from traditional IRA. Penalty-free but locked in for 5 years or until 59.5 (whichever longer). Three IRS-approved calculation methods: RMD, amortization, annuitization.

Rule of 55

Separate from employer at age 55 or later → 401k penalty-free (IRA not eligible). Useful for layoffs or early retirement at 55–59.
