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?

- 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.
