How to use the Heat Pump Calculator
Walk through using the Heat Pump Calculator with Delaware-specific defaults pre-loaded from primary sources.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.

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 Delaware page uses the property tax rate (0.58%), median home price ($350,000), and 6.6% state income tax from the sources listed below.
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.
