How we calculate

Energy cost = monthly kWh × $/kWh. Monthly total = energy cost + fixed monthly fee. Yearly total = monthly total × 12. The stack bar shows energy vs fixed as a share of the monthly total. The 12-month chart stacks cumulative energy and fixed fee assuming this month’s estimate repeats — not seasonal or tiered.

Frequently asked questions

Is this a live utility bill?
No. The calculator uses editable US ballpark defaults, not your utility's rates, fees, or taxes. Update the fields to match your bill.
How is the estimate calculated?
Energy cost = monthly kWh × price per kWh. Monthly total = energy cost + fixed monthly fee. Yearly total = monthly total × 12.
What is the fixed monthly fee?
Many utilities charge a delivery or customer fee even if you use little electricity. Set it to 0 if your bill has no fixed charge.
Does this include tiered or time-of-use rates?
No. This is a simple flat-rate model. Tiered, TOU, demand charges, and solar credits are out of scope for this calculator.
What does the 12-month chart show?
It stacks cumulative energy cost and fixed fee over 12 months, assuming this month’s estimate repeats each month. It is not a seasonal or tiered forecast.
