Electricity Rate per kWh Calculator
Determine exactly how much you are paying for every kilowatt-hour of electricity used.
How to Calculate Your Electricity Rate
Understanding your electricity bill starts with knowing your "Rate per kWh." While utility companies often list a "supply rate," your actual cost is usually higher once delivery charges, taxes, and regulatory fees are added. This calculator provides your effective rate, which is the total cost divided by the total energy consumed.
To find the necessary figures, look at your most recent utility statement. You will need:
- Total Bill Amount: The final amount you are charged, including all fees.
- Total Usage (kWh): The amount of electricity used during the billing cycle, measured in kilowatt-hours.
The Formula
The math behind the calculator is straightforward:
Example Calculation
If your monthly bill is $160.00 and your meter shows you used 1,100 kWh, the calculation would be:
$160.00 ÷ 1,100 kWh = $0.145 per kWh (or 14.5 cents per kWh).
Why Knowing Your Rate Matters
| Benefit | Description |
|---|---|
| Comparison | Allows you to compare your local utility rates against national averages or alternative suppliers. |
| Appliance Costs | Knowing your rate lets you calculate exactly how much it costs to run a space heater, AC, or EV charger. |
| Solar ROI | Essential for calculating the "Payback Period" if you are considering installing solar panels. |
Typical Electricity Rates
Electricity prices vary significantly by region and season. In the United States, the average residential electricity rate typically fluctuates between $0.12 and $0.20 per kWh. Areas like Hawaii or the Northeast often see much higher rates (up to $0.40/kWh), while states with significant hydroelectric or natural gas production may see rates below $0.10/kWh.
