Heating Cost Calculator

Heating Cost Calculator

Convert the heater's wattage to kilowatts, multiply by hours and rate, then show the monthly cost.

Method and assumptions

Energy cost is estimated by multiplying kilowatts by hours used and your electricity rate. The calculation runs in your browser.

• Wattage, hours used, and the electricity rate stay constant for the period.
• Fixed charges, time-of-use pricing, taxes, and changing power draw are excluded unless entered separately.
• For better accuracy, use the appliance label and the rate on your latest utility bill.
