Home Energy Cost Calculator — Bill Breakdown 2026
Calculate your monthly electricity bill by appliance in 2026. Find your biggest energy users and see how much solar or efficiency upgrades could save.
Estimate scope & data quality
This tool provides an input-driven estimate. Use the required inputs shown above and review the result limitations below.
- Data quality

- Result limitation
- Calculator output is not a source-complete customer result.
A tariff credit is distinct from annual savings. If a result is NOT_COMPUTABLE or CONFLICT, it must not be replaced with an estimate or treated as canonical.
How to use this calculator
- Adjust the refrigerator kWh/day slider — check your fridge's EnergyGuide 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; the calculator assumes a 2.5 kW average draw.
- 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 US residential average is $0.182/kWh (EIA, July 2026 year-to-date).
Understanding your results
HVAC is almost always the biggest energy user: Heating and cooling typically account for 40–50% of a US home’s energy 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. At the default settings (1.5 kWh fridge, 5 washer loads/week, 6 HVAC hours, 4 kWh water heating, 2 kWh lighting, $0.182/kWh) the calculator shows about 22.9 kWh/day, or roughly $4.17/day, $127/month and $1,520/year for these loads.
Water heating is second: Electric resistance water heaters draw 3,000–4,500 W and run 2–3 hours per day, adding 3–5 kWh/day. A heat pump water heater cuts that to about 1–2 kWh/day, typically saving a few hundred dollars a year at US-average rates. See the heat pump water heater calculator.
Lighting is now minimal with LEDs: A home with LED bulbs uses 0.5–2 kWh/day for lighting — a 75–85% reduction compared with incandescent bulbs. Replacing the last incandescent bulbs is one of the cheapest efficiency upgrades available.
How to lower your actual bill: (1) Thermostat setbacks — each degree of heating setback saves roughly 1–3% on heating costs. (2) Water heater temperature — lowering it from 140°F to 120°F saves on standby and heating losses. (3) Phantom loads — switching off idle electronics trims standby use. (4) Solar panels — under the site’s standard model, a right-sized system removes about 55–87% of the electric bill in year 1, depending on your state’s net-metering rules (0.75 national average).
2026 incentive status: Federal tax credits for home efficiency upgrades (§25C) and homeowner-owned solar and batteries (§25D) ended for projects completed after Dec 31, 2025, under the One Big Beautiful Bill Act (Public Law 119-21) (IRS FAQ). Payback for 2026 upgrades comes from bill savings plus any state HEAR/HOMES or utility rebates — check your state energy office or DSIRE. This is not tax advice; confirm with a tax professional.
