Your bill is a useful starting document for an energy project. Find the billing dates, usage in kWh, utility name, rate-plan name, and the current period’s electricity charges.

Keep the comparison consistent.

Separate current electricity charges from an old balance, late fees, or unrelated services. If your bill has separate supply and delivery sections, keep both visible. Read the actual rate schedule to understand the charges that apply.

Use a blended-cost calculation carefully.

Dividing a comparable set of current electricity charges by the period’s kWh produces an effective average cost. It does not necessarily equal an advertised energy-only rate. Our calculator performs that arithmetic with the numbers you enter.

Collect more than one month.

Electricity use and prices can vary. Bring several bills to your review and note expected changes, such as new equipment or an EV. Ask how a proposal handles those differences rather than treating one month as a forecast.

Keep account numbers private. This preview does not need a bill upload. Use the calculator locally and bring detailed documents to a verified project review later.
