About This Calculator
This calculator estimates your total monthly home energy cost based on your average monthly electricity usage (in kWh, found on a past bill) and your electricity rate — a quick whole-home estimate, as opposed to the Electricity Cost Calculator's single-appliance focus.
How This Is Calculated
Monthly Bill = (kWh Used × Rate) + Fixed Service Fee
900 kWh at $0.16/kWh plus a $10 service fee comes to about $154/month.
Assumptions
- Uses a flat electricity rate; actual bills may include tiered pricing, delivery charges, or seasonal rate changes.
- Does not include gas or other utility costs.
