How to find your rate and read your electric bill

Quick method: divide the total amount you paid by the total kWh used in the same bill. That gives your all-in cost per kWh, including fees.

Steps

1. Find "kWh used" for the billing period.
2. Find the total amount due (not including any past balance).
3. Divide amount by kWh.
4. Type that number into the calculators.

Your bill may also list a supply charge and a delivery charge separately. Adding them gives the all-in rate. Some plans charge different rates at different times of day; in that case use the rate for the hours you run the appliance.

Bill layouts differ by utility. If a line is unclear, your utility's customer service can explain it.
