What this calculator is doing
It separates usage-based energy cost from the charges that stay on the bill even when usage drops. That all-in effective rate is often higher than the advertised kWh rate.

FAQ
Short answers for search visitors and bill-checking moments.
Why is my effective electricity rate higher than my kWh rate?
The effective rate includes fixed charges, delivery charges, taxes, and fees. Those charges make the all-in cost per kWh higher than the energy-only rate.
Is this calculator a replacement for my utility bill?
No. It is an estimate and explainer. Your utility bill remains the source of truth for actual rates, taxes, and billing rules.
