How this calculator works
- Your monthly bill is the price per kWh × your monthly kWh, plus the fixed monthly charge. The yearly estimate is the monthly bill × 12.
- Your effective rate is the monthly bill ÷ your monthly kWh, so it includes the fixed charge.
- Every kWh is priced the same. Tiers, time-of-use periods, seasons, minimum bills, credits, taxes, and other charges aren’t included unless you build them into the price or the fixed charge.
- Amounts are rounded to the cent only when shown.
