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.
The starter rate is only one part of the bill. Delivery charges, fixed customer fees, riders, local taxes, and billing period length can all change the final monthly amount.
If your bill shows separate supply and delivery charges, enter the supply rate in the rate field and place delivery, customer charges, and taxes in the separate line items.
