How is a Pennsylvania electric bill figured?
A bill has three working parts. Supply is the power itself, priced per kWh. Delivery is a per-kWh distribution charge. The fixed customer charge is a flat amount each month, whatever you use.
| Part of the bill | Who sets it | Does a supplier change it? |
|---|---|---|
| Supply price per kWh | You choose a supplier, or your utility sets its price to compare | Yes |
| Supplier monthly fee | The supplier | Yes |
| Delivery price per kWh | Your utility, under a tariff filed with the PUC | No |
| Fixed customer charge | Your utility, under the same tariff | No |
| Taxes and small surcharges | The state and the utility | No |
The calculator reads each utility's filed tariff for the delivery and fixed lines, and the PA Power Switch list for the price to compare. It holds delivery the same for all 12 months, because the next quarterly reset is not known today.
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 supplier box blank to see your bill at your utility's own price. Type a supplier's price and its monthly fee, if any, to see the two 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 and delivery tariff as we last read them, and holds your kWh the same all year. 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.

Run it twice, once with a hot month's kWh and once with a mild month's. The fixed charge is a bigger share of a low bill, and the per-kWh parts grow with use.
What price is the calculator using for my utility?
Find your utility on your bill. The price to compare is what your utility charges for supply. It is the number the calculator uses when the supplier box is blank.

Prices come from PA Power Switch, last read October 24, 2026, and a robot keeps them current. A price marked as next is an early estimate the utility posted itself, so the final price can differ. For what the number means and when it resets, read our price to compare guide.
How does the math work? A made-up example
Here is a made-up bill, with round numbers that are not any utility's. You use 1,000 kWh. Supply is 10.0¢ per kWh. Delivery is a $12 fixed charge plus 5.0¢ per kWh.
| Line | How it is figured | Cost |
|---|---|---|
| Supply | 1,000 kWh x 10.0¢ | $100.00 |
| Delivery per kWh | 1,000 kWh x 5.0¢ | $50.00 |
| Fixed customer charge | Flat | $12.00 |
| Bill for the month | Sum of the three | $162.00 |
| Bill for 12 months | 12 x $162.00 | $1,944.00 |
Now a supplier offers 9.0¢ with no fee. Supply drops to $90.00 and the bill to $152.00. That saves $10.00 a month and $120.00 over the year. Delivery did not move, because the supplier cannot change it. This is why the calculator compares only the supply side.
Do not compare a supplier's price with your whole bill. Compare it with your utility's supply price. Delivery is the same either way.
Why might my real bill differ from the estimate?
The calculator is built to be close, not exact. These are the usual reasons for a gap.
- Delivery comes from the utility's own filed tariff, with the source named in our data.
- You can type your own delivery charges from a bill to replace ours.
- Your kWh in a month is not the figure you typed.
- Your utility reset its delivery or its price to compare partway through the year.
- Taxes and small surcharges, which the tool leaves out, were added.
- You are on a heating, all-electric or other schedule. The tool reads the main residential schedule only.
- A supplier's price is variable, so it can move each billing period.
What should I do with the answer?
If the supplier box was blank, you now know your utility's bill. If you were given an offer, you know whether it beats that bill over 12 months.
- 1Check your kWh.
Use the number on your latest bill, or the hot and mild months.
- 2Run your utility alone.
This is the bill you pay if you do nothing.
- 3Run each offer.
Type the price and any monthly fee. Compare like with like: fixed with fixed.
- 4Read the paperwork.
Check the end date, the cancel fee and the renewal line in the disclosure statement.
- 5Set a reminder.
The tool can save a calendar date for your utility's next price change.

Questions, answered
How do I calculate my electric bill in Pennsylvania from kWh or a meter reading?
Multiply your kWh by the supply price per kWh. Add your utility's delivery charge per kWh times your kWh, then add the fixed customer charge. Your bill already shows the kWh. If you only have meter readings, subtract last month's reading from this month's and use that gap. The calculator on this page does the rest.
How is an electric bill figured, with an example?
Add three lines: supply, delivery and a fixed charge. In our made-up bill at 1,000 kWh, supply is $100.00, delivery per kWh is $50.00 and the fixed charge is $12.00. That makes $162.00 for the month. The example above shows each step.
Is there a Pennsylvania electric bill calculator by ZIP code?
Ours works by utility, not ZIP. The supply price and the delivery charge belong to your utility, and the bill names it. Pick that utility and your kWh.
What is an average electric bill in Pennsylvania?
It depends on your kWh, your utility and the season. Use your own kWh in the calculator, because a state average hides large differences between homes.
Does a supplier change my delivery charge?
No. Your utility sets delivery under its tariff, and every customer in the area pays it. A supplier changes only the supply price and its own fees.
What is the price to compare?
It is your utility's supply price per kWh. A supplier's offer only beats it if the offer costs less over the time you would hold it. See our price to compare guide.
Why is UGI shown as supply only?
We have no delivery tariff on file for UGI Electric. The tool says so and lets you type your delivery charges from a bill to get a full figure.
Does the calculator include taxes?
No. It leaves out taxes and small surcharges, so a real bill can differ by a few dollars.
How often do delivery charges change?
Some parts reset every quarter, and a utility can file a new tariff. We hold the charges the same for all 12 months and show the date the tariff took effect.
Is the electricity cost calculator free?
Yes. It needs no ZIP code or sign-up, and nothing you type is saved or sent.
Can I use it for a business or an electric-heat plan?
No. It is built for the main residential schedule of each utility. Heating and other plans have different delivery rates.
