How is an Ohio electric bill figured?
A bill has a supply line, delivery lines and often a fixed monthly charge. Only the supply line changes when you pick a seller.
| Part of the bill | Who sets it | Does a seller change it? |
|---|---|---|
| Supply price per kWh | You choose a seller, or your utility sets its price to compare | Yes |
| Seller monthly fee | The seller | Yes |
| Delivery per kWh | Your utility | No |
| Fixed customer charge | Your utility | No |
| Taxes and small surcharges | The state and the utility | No |
Your bill names each line. Add up the delivery and fixed lines and type the total in the calculator's delivery box. Your city may also buy power for all homes at its own rate; if so, compare against that rate too.
What will my bill be? The free calculator
Pick your utility. Enter the kWh from your bill; the box starts at a round 1,000 kWh. You do not need your ZIP code. Leave the seller box blank to see your bill at your utility's own price. Type a seller's price and monthly fee, if any, to see both side by side over 12 months.
Pick your utility and press "Work out my bill". You get the bill for one month and for 12 months at your utility's price. Add a supplier's price to see how it compares.

This is an estimate, not a bill. It uses your utility's price to compare as we last read it and shows the date that price ends. Delivery and fixed charges are only in the answer if you type them. It leaves out taxes and small surcharges. You can save a calendar reminder for the next price change or print the result. The tool keeps nothing you type.

Use a hot month and a cold month. Ohio homes that heat with electricity use far more in winter.
What price is the calculator using for my utility?
The price to compare is what your utility charges for supply. The "price ends" date is the last day that price is posted to hold.
| Utility | Price to compare | Posted since | Price ends |
|---|---|---|---|
| AEP Ohio | 10.19¢ | Oct 1, 2026 | Dec 31, 2026 |
| Duke Energy Ohio | 10.49¢ | Oct 1, 2026 | Oct 31, 2026 |
| AES Ohio | 10.86¢ | Jun 1, 2026 | May 31, 2027 |
| Ohio Edison | 11.07¢ | Oct 1, 2026 | Dec 31, 2026 |
| Cleveland Electric Illuminating | 11.24¢ | Oct 1, 2026 | Dec 31, 2026 |
| Toledo Edison | 11.26¢ | Oct 1, 2026 | Dec 31, 2026 |
The prices come from the Energy Choice Ohio charts, last read October 24, 2026, and a robot keeps them current. When a price ends before the 12 months are over, the calculator keeps the last price it knows for the rest and says so. Type the price from your bill to make it exact.

How does the math work? A made-up example
Here is a made-up year with round numbers that are not any utility's. You use 1,000 kWh a month. Your utility posts a supply price of 10.0¢ that holds for the first six months. After that, the new price is not posted yet.
| Months | What we know | Supply each month | Supply for the stretch |
|---|---|---|---|
| 1 to 6 | The posted price, 10.0¢ | $100.00 | $600.00 |
| 7 to 12 | Nothing posted, so the last price is kept as a guess | $100.00 | $600.00 |
| Year | $1,200.00 |
Half of that year is a guess. If the new price turns out to be 11.0¢, months 7 to 12 cost $110.00 each, which adds $60.00 and makes the year $1,260.00. The calculator shows this split so you know how much of its answer to trust.
Delivery is not in this example. Type your delivery lines from your bill to turn a supply figure into a full bill.
Why might my real bill differ from the estimate?
- The tool says how many months rest on a price we know.
- You can type the new price the day your utility posts it.
- Your utility posted a new price after the old one ended.
- The delivery box was blank, so the answer shows supply only.
- Your kWh moved with the weather, most of all if you heat with electricity.
- A seller's variable price changed after you priced it.
- Taxes and small surcharges were added to the bill.
What should I do with the answer?
Start with your bill, then test the seller's offer.
- 1Read your latest bill.
Note the kWh and the delivery and fixed lines.
- 2Type the delivery total.
One number in the delivery box is enough.
- 3Price your utility first.
That is your bill if you do nothing.
- 4Price the seller's offer.
Add its fee.
- 5Check the contract terms.
Look for the end date, the early termination fee and the renewal line.
- 6Save the reminder.
The tool can mark the day your utility's posted price ends.

Questions, answered
How do I figure my electric bill in Ohio?
Multiply your kWh by the supply price, then add the delivery and fixed lines from your bill. The calculator starts from your utility's price and adds up 12 months.
How is an electric bill calculated, with an example?
Add up the kWh times the supply price, the delivery lines and the fixed charge. In our made-up year at 1,000 kWh and 10.0¢, supply is $100.00 a month, or $1,200.00 for the year, before delivery. Half of that year rests on a price not yet posted.
What is the average monthly electric bill in Ohio?
It depends on your kWh, your utility and the season, so one state average would hide large gaps. Ohio homes that heat with electricity use far more in winter. Try a hot month and a cold month in the calculator.
Is there an Ohio electric bill calculator by ZIP code?
Ours works by utility. The price to compare is set for each utility, and a city program can set its own rate. Your bill names your utility, so pick it and type your kWh.
Why does the answer say supply only?
Our data has no Ohio delivery charges. Type the delivery and fixed lines from your bill into the delivery box and you get a full bill.
Can a seller lower my delivery charge?
No. Your utility keeps delivery whichever seller you pick. A seller changes the supply price and its own fees.
What is the price to compare in Ohio?
It is your utility's supply price for a set period. A seller's offer beats it only if it costs less over the time you would hold it.
What does the tool do when my utility's price ends?
It keeps the last price it knows for the rest of the year and counts those months as a guess.
Are taxes counted?
No. A real bill can differ by a few dollars for taxes and small surcharges.
Does it cost anything?
No. It has no ZIP box or sign-up, and nothing you type is saved or sent.
What if my city buys power for everyone?
Use your city's rate. Type it in the tool's box for your utility's price to compare.
