How to Read Your US Electric Bill

Find the kWh, cents-per-kWh rate, supply and delivery charges, fixed fees and adjustments on a US electricity bill, with a worked example.

Start with the billing period and meter

Before comparing totals, check the service address, meter number and start/end dates. A longer billing period can cost more even when daily consumption is unchanged. Use the number of billed days rather than assuming every bill covers exactly one month.

Look for the billed kWh and whether the reading is actual or estimated. If there was a meter exchange or multiplier, the utility’s billed consumption is a better starting point than subtracting two display numbers yourself.

Separate the energy price from the other charges

Some bills combine the electricity price into one line. Others show supply or generation and delivery charges separately. A fixed customer fee is different from a charge that rises with each kWh. The labels depend on the utility and state.

For our flat-rate calculator, add applicable per-kWh supply and delivery rates together. Enter fixed fees and any other applicable taxes or charges separately in dollars. An average rate calculated by dividing the entire bill by kWh already includes those extras; adding them again would double-count them.

Worked example: a $164.40 bill

Suppose a 30-day bill covers 900 kWh. The supply rate is 10¢/kWh and delivery is 6¢/kWh, giving a combined rate of 16¢. Electricity charges are 900 × 16 ÷ 100 = $144.

Add a $12 fixed customer charge and $8.40 in other taxes and fees: $144 + $12 + $8.40 = $164.40. These invented figures explain the method; they are not a utility quote or an average US bill. The average daily cost is $164.40 ÷ 30 = $5.48.

Current charges are not always the amount due

The payment section may also contain unpaid amounts from earlier bills, payments received, credits, deposits or payment-plan adjustments. Keep those separate when checking the cost of electricity used during the latest period.

Budget billing may smooth payments rather than charging exactly the cost of that month’s use. Compare the underlying usage and charges as well as the installment amount.

Check special pricing before using a single rate

On a time-of-use plan, different hours can have different prices. A tiered plan can charge a different rate once a usage threshold is reached. A demand charge is based on a power measure rather than simply total kWh.

Solar export credits also need their own treatment. Check your utility’s rate schedule and bill explanation for the relevant state and plan. Our calculator does not reconstruct these more complex schedules automatically.

If something still does not add up

Keep the bill, dates and a meter photo if safely accessible. Ask the utility which charge or reading explains the difference. Request its calculation and the applicable rate schedule before assuming that a meter is faulty.

For a useful month-to-month comparison, write down kWh per day, the applicable price, fixed charges and any one-off adjustments. That separates increased consumption from a higher rate or an old balance.
