How to Estimate Your Electric Bill
The core formula is cost = kWh used × price per kWh, plus any fixed monthly service charge. Many utilities use tiered (inclining block) pricing, where higher usage is billed at higher rates.
Tiered Pricing Example
| Block | Rate |
|---|---|
| First 500 kWh | $0.14/kWh |
| 501 – 1,000 kWh | $0.22/kWh |
| Above 1,000 kWh | $0.32/kWh |
Thresholds, rates and fixed charges vary by utility and state — adjust the inputs to match your bill. Taxes and fees are not included.
Frequently Asked Questions
- How is an electricity bill calculated?
- Energy charge = usage (kWh) × price per kWh. Add any fixed monthly service charge to get your total. For example, 900 kWh at $0.17/kWh plus a $10 fixed charge is $163.00.
- What are tiered (block) rates?
- Some utilities charge more as you use more. The first block of kWh is billed at a lower rate, and usage above each threshold is billed at higher rates. Switch to the "Tiered rates" tab to model this.
- What is the average price per kWh?
- It is your total bill divided by total kWh used. With tiered rates and fixed charges, the average price differs from any single tier rate.
- What is a typical US electricity rate?
- The US residential average is roughly $0.16–$0.18 per kWh, but it varies widely by state and utility. Check your bill for your exact rate and any fixed charges.
