About this calculator
Your electric bill is your total kilowatt-hour usage multiplied by your utility's per-kWh rate, plus any fixed monthly service or base charge. This calculator projects your bill from expected usage and rate, and can also estimate usage from your typical appliance load if you don't have a meter reading handy.
Worked example
Using the values the calculator loads with:
Inputs
- Estimated monthly kWh usage: 900 kWh
- Electricity rate: 0.16 $/kWh
- Monthly base/service fee: 10 $
Results
- Estimated total bill: $154.00
- Usage charges: $144.00
- Base/service fee: $10.00
What each field means
Inputs
- Estimated monthly kWh usage (kWh)
- The estimated monthly kwh usage used in the calculation, measured in kWh. Starts at 900 kWh so you have a working example on load.
- Electricity rate ($/kWh)
- The electricity rate used in the calculation, measured in $/kWh. Starts at 0.16 $/kWh so you have a working example on load. Accepted range: 0.05–0.6 $/kWh.
- Monthly base/service fee ($)
- The monthly base/service fee used in the calculation, measured in $. Starts at 10 $ so you have a working example on load.
Results
- Estimated total bill
- Returned as a money amount in US dollars and shown as the headline result. It recalculates instantly whenever you change an input, so you can compare scenarios without reloading.
- Usage charges
- Returned as a money amount in US dollars. It recalculates instantly whenever you change an input, so you can compare scenarios without reloading.
- Base/service fee
- Returned as a money amount in US dollars. It recalculates instantly whenever you change an input, so you can compare scenarios without reloading.
FAQ
How much will my electric bill be?
At 900 kWh usage, 16¢/kWh rate, and a $10 base fee, the estimated bill is $154 for the month.
What's the average U.S. household's monthly usage?
The U.S. average is roughly 900-1,000 kWh per month, though it varies widely by climate and home size — heavy AC or electric heating users can see 1,500+ kWh in peak months.
Does this account for tiered or time-of-use rates?
This model uses a flat blended rate; if your utility charges tiered rates (higher price per kWh after a threshold) or time-of-use pricing, your actual bill may differ from this straight-line estimate.
How can I estimate my kWh usage without a meter reading?
Add up your major appliances' wattage times daily hours of use, divide by 1000, and sum across all appliances — or check last year's bill for the same month as a seasonal baseline.
Accuracy and limitations
- Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
- Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.
- This is educational maths, not financial advice. Check anything contractual with the lender or your accountant.
