How to estimate electricity cost
Enter the total energy usage for a billing period in kilowatt-hours (kWh) and the rate charged for each kWh. The calculator multiplies those values to estimate the energy charge. The result uses the same currency units as the price per kWh.
Electricity cost formula
Estimated cost is calculated as energy usage (kWh) × price per kWh. For example, using 350 kWh at 0.20 per kWh gives an estimated energy charge of 70.
Estimate only
This estimate covers only the energy charge based on the rate you enter. It does not include fixed service fees, demand charges, taxes, tiered rates, time-of-use pricing or other adjustments on a utility bill. Check your provider's tariff and bill for the actual amount.
