Calculate your electricity costs based on usage and rate
Learn how to use the Electricity Cost Calculator calculator and its working principles
The calculator uses the following simple formula to estimate your electricity cost:
Monthly Cost = kWh Usage × Electricity Rate
For example, if you use 500 kWh of electricity in a month and your rate is $0.15 per kWh, your estimated monthly cost would be:
500 kWh × $0.15/kWh = $75.00
