Electricity cost calculator: how much each appliance spends
Pick the appliance (or enter its watts), the hours you use it per day and your price per kWh, and we'll tell you how much it adds to your electricity bill. With the math in plain sight.
Consumption and cost
| Consumption per month | 0 kWh |
| Cost per day | $ 0 |
| Cost per month | $ 0 |
| Cost per year | $ 0 |
Air conditioners, water heaters, fridges and thermostat heaters do NOT draw full power all the time: they cycle on and off to hold the temperature. Enter the hours of actual operation (less than the hours it's switched on), or the result will come out higher than the real one.
An old or inefficient appliance can cost you more in electricity than replacing it would. We compare the most efficient models in our guides, with real prices.
How it's calculated
- Consumption (kWh) = watts ÷ 1000 × hours of use.
- Cost = consumption (kWh) × your price per kWh.
- We multiply by the days of use to give you the monthly total.

Indicative estimate. Real power depends on the model and how you use it; the price per kWh varies by region, tariff and subsidy. For an exact figure, check the watts on your appliance's label and the kWh price on your bill.
