Untick or zero-out anything you don't have, and adjust hours to match your actual routine — the default hours are typical starting points, not your home's real usage.
Using this alongside your panel
- This is an energy-cost picture, not an electrical-capacity one — for whether your panel can handle everything running at once, see our Household Load Calculator.
- Big-ticket items (water heater, dryer, A/C, EV charger) usually dominate the total — start there if you're looking to trim the bill.
- Compare this estimate against a real utility bill to sanity-check your hours-per-day inputs.
