THE METHOD

Transparent enough
to check by hand.

WATTS×HOURS×DAYS×DUTY×RATE

Planning estimate, not a bill prediction. State figures are EIA residential averages. Your tariff, weather, equipment condition, fixed fees, taxes, standby power, and time-of-use pricing can change the result.

Simple payback is intentionally simple. It excludes financing, maintenance, rebates, energy-price escalation, and equipment life. Calculations retain full precision; rounding is display-only.
