Tools & Calculators
Appliance calculators, built on certified data
These calculators will run on the certified corpus already live behind the rest of the site (15,477 products, DOE CCMS / ENERGY STAR) — no sign-up, no sales call. In the meantime every product page already shows a computed running-cost figure with state-price extremes; the heat-pump-dryer payback tool ships first here (ARCHITECTURE.md: dryers = strongest money stat).
Heat-Pump Dryer Payback Calculator Coming soon
Enter your electricity price and dryer usage → years to break even on the $400-800 heat-pump-dryer premium. First tool (biggest money stat).
Running-Cost Calculator Coming soon
Enter your local electricity price → annual dollar cost for any certified washer, dryer, dishwasher or refrigerator.
Capacity-Truth Checker Coming soon
Look up a refrigerator by model → see advertised volume next to the DOE-adjusted number.
Calculators will use published performance ratings and EIA energy prices. Formulas are documented in our methodology. We never estimate a spec that isn't published — missing values render as "not published," never guessed.
