How would you like to enter usage?
2

Your utility charges

Enter your own rate; no national average is assumed.

Enter 16 for 16¢/kWh ($0.16/kWh). Include both supply and delivery charges per kWh if your utility lists them separately.

Leave optional charges at $0 if none apply. Enter dollar totals for the whole period, not daily charges or tax percentages. Do not add charges already included in your rate.

We record anonymous usage and charge figures for separate US statistics. Your meter readings are not sent. Privacy policy.

How it works

How to calculate a US electric bill

Electricity cost = kWh used × cents per kWh ÷ 100. Add the fixed charges and other dollar amounts for the period.

01

Find your kWh usage

Use the consumption on your utility bill, or subtract the previous meter reading from the current reading.

02

Check your electricity rate

Use your utility’s price per kWh, including applicable supply and delivery rates. Rates vary by utility, location and plan.

03

Add period charges

Add fixed customer charges and any taxes or fees not already included. For example, 900 kWh at 16¢ costs $144; adding $12 in fixed charges and $8.40 in taxes and fees gives $164.40.

Understand your estimate

Does this work with every electricity plan?

This calculator uses one flat rate. It does not automatically calculate tiered rates, time-of-use pricing, demand charges, minimum bills or solar export credits. Use your utility’s bill breakdown for those plans.
