Actual use can differ when equipment cycles or changes power. Measure at the wall when precision matters.
A statewide average cannot reproduce your utility rate plan. Check whether your bill includes tiered pricing, time-of-use periods, a longer billing cycle, fuel or delivery adjustments, fixed customer charges, taxes, or credits.
Use your actual all-in price when possible
For a personal estimate, divide the total electric charges on your bill by the total kWh used. That captures the combined price represented on that bill.
total electric charges ÷ total kWh = your all-in $/kWh
