How to use this calculator
- Adjust the refrigerator kWh/day slider — check your fridge's Energy Guide label or use 1.0–2.0 kWh for most modern fridges.
- Enter washing machine loads per week — the calculator assumes 0.5 kWh per load for a modern efficient washer.
- Set HVAC hours per day — this is the biggest variable in most homes. Use seasonal averages.
- Enter water heater kWh/day — 3–5 kWh for electric resistance, 1–2 kWh for a heat pump water heater.
- Enter your actual electricity rate from your utility bill ($/kWh). The national average is $0.163/kWh in 2026.
Understanding your results
HVAC is almost always the biggest energy user: Heating and cooling typically account for 40–50% of a US home’s electricity bill. At 2.5 kW average draw and 6 hours/day of runtime, HVAC adds 15 kWh/day — more than refrigerator, lighting and washer combined.
Water heating is second: Electric resistance water heaters use 3,000–4,500W and run 2–3 hours per day, adding 3–5 kWh/day. Switching to a heat pump water heater reduces this to 1–2 kWh/day — a $300–$500/year saving at national average rates.
Lighting is now minimal with LEDs: A home with LED bulbs uses 0.5–2 kWh/day for lighting — a 75–85% reduction compared to incandescent bulbs. Replacing the last incandescent bulbs is among the highest-ROI efficiency upgrades available.
How to lower your actual bill: (1) Thermostat setbacks — each degree of heating setback saves 1–3% on heating costs. (2) Water heater temperature — most are set to 140°F; reducing to 120°F saves 6–10% on water heating. (3) Phantom loads — unplugging unused electronics eliminates 5–10% of your bill. (4) Solar panels — a correctly-sized system can offset 80–100% of your total electricity consumption.
