Electricity Bill Calculator

How this estimate works

This calculator is useful when you are moving, comparing a bill with household usage, or estimating the impact of a rate increase.

Use your equipment data. Check a label, specification sheet, controller, or energy meter.
Enter your utility rate. A recent bill is more useful than a national average.
Test different schedules. Change one input at a time to compare scenarios.

Compare your kWh use—not only the dollar total—with the previous month.

Check whether your utility uses tiered or time-of-use pricing.

Use appliance calculators to identify the largest loads in your home.

Transparent methodology

Results use the values you enter and standard energy formulas. They are planning estimates, not bills or guarantees.

What is a typical U.S. household electricity use?+

Usage varies by climate, home size, heating fuel, and appliances. Your own 12-month billing history is the most useful benchmark.

Does this estimate include taxes?+

No. Taxes, riders, demand charges, credits, and local adjustments vary by utility.

Where can I find my electricity rate?+

Divide the energy-related portion of your bill by billed kWh, or use the rate explicitly listed by your utility.

How to verify this estimate

Use the variable energy rate and keep fixed customer charges separate.

Compare the result with billed kWh and the exact number of billing days.

Tiered rates, taxes, riders, credits, and minimum bills can make a flat-rate estimate differ from the utility bill.
