Electricity Cost Calculator: Estimate Your Monthly and Annual Bill

Select your state from the dropdown (your state's average rate is pre-loaded). Adjust the monthly usage slider to match your typical consumption (check your latest bill for your kWh number). The calculator instantly shows your estimated monthly and annual cost, daily cost, and how your costs compare to the national average and the cheapest and most expensive states. You can optionally enter a custom rate to see exact costs for your specific plan.

The national average is 886 kWh per month. However, this varies significantly by home size and climate. A small apartment typically uses 400 to 600 kWh. A small house uses 600 to 800 kWh. An average house uses 800 to 1,000 kWh. A large house uses 1,000 to 1,400 kWh. A large house with an EV charger and electric heating can use 1,400 to 2,000+ kWh. Check your utility bill for your actual number.

The calculator uses real average residential rates from the EIA for each state. It provides a reliable estimate of your costs based on these averages. Your actual bill may differ slightly because: (1) your specific rate plan may differ from the state average, (2) your bill includes delivery charges and taxes not captured in the per-kWh rate, and (3) seasonal rate tiers may apply in your state. For the most accurate picture, enter your actual rate from your latest bill using the custom rate field.
