What will this appliance cost to run?
Convert appliance wattage, daily usage, and your electricity rate into daily, monthly, and annual running costs with Figur.
Calculate an appliance's electricity cost
Electricity use is wattage divided by 1,000 to get kilowatts, multiplied by hours used. Figur multiplies that daily use by your rate and by 30 or 365 days for planning estimates.
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.
