Electricity Bill Calculator
Calculate your total monthly electricity bill from overall kWh usage with flat, tiered, or time-of-use rate structures. Includes solar net metering, demand charges, taxes, and year-over-year comparison.

How to Use This Calculator
- Enter your Monthly kWh Usage — find this on your electricity bill.
- Enter your Rate per kWh and any Fixed Monthly Charge (customer/service charge).
- See your monthly bill, annual cost, and effective all-in rate instantly.
- Use the Tiered Rate tab if your utility charges different rates above a usage threshold.
- Use the Time of Use tab to calculate bills with separate peak and off-peak rates.
- Use the Professional tab for solar net metering, demand charges, taxes, carbon emissions, and year-over-year comparison.
Formula
Monthly Bill = (kWh × $/kWh) + Fixed Charge
Tiered: Bill = (Tier1 kWh × Rate1) + (Tier2 kWh × Rate2) + Fixed
TOU: Bill = (Peak kWh × Peak Rate) + (Off-Peak kWh × Off-Peak Rate) + Fixed
Net Metering: Net kWh = Usage − Solar Production; excess solar credited at export rate
Tiered: Bill = (Tier1 kWh × Rate1) + (Tier2 kWh × Rate2) + Fixed
TOU: Bill = (Peak kWh × Peak Rate) + (Off-Peak kWh × Off-Peak Rate) + Fixed
Net Metering: Net kWh = Usage − Solar Production; excess solar credited at export rate
Example
Example: 900 kWh usage, $0.16/kWh rate, $12 fixed charge.
Monthly bill: 900 × $0.16 + $12 = $156/month | Annual: $1,872 | Daily: $5.12
With tiered rate (500 kWh at $0.12 + 400 kWh at $0.22): $60 + $88 + $12 = $160/month
Monthly bill: 900 × $0.16 + $12 = $156/month | Annual: $1,872 | Daily: $5.12
With tiered rate (500 kWh at $0.12 + 400 kWh at $0.22): $60 + $88 + $12 = $160/month
Frequently Asked Questions
- Your bill = (kWh used × energy rate) + fixed customer charge + taxes and fees. Most residential bills in the US range from $80-$200/month. The average US rate is about $0.16/kWh as of 2026, but varies widely by state — Hawaii averages $0.37/kWh while Louisiana averages $0.10/kWh.
- Tiered (or stepped) rates charge a lower rate for the first block of usage (e.g., first 500 kWh at $0.12/kWh) and a higher rate for usage above that threshold (e.g., $0.22/kWh). This encourages conservation and is common in California and other states.
- TOU pricing charges different rates depending on when you use electricity. Peak hours (typically weekday afternoons 4-9 PM) cost more, while off-peak hours (nights, weekends) are cheaper. TOU plans reward shifting usage to off-peak times — running dishwashers and EV charging overnight reduces your bill.
- With net metering, excess solar electricity you generate is exported to the grid and credited to your account at the net metering rate (often lower than your purchase rate). Net billed usage = consumption minus solar production. If solar exceeds consumption, you receive a credit on your bill.
- The Electricity Cost Calculator estimates the running cost of a single appliance (e.g., how much does your TV cost per month). This calculator estimates your total monthly electric bill from whole-home kWh usage with complex rate structures, solar offsets, demand charges, and taxes.
