How do I calculate kWh from electric meter readings?
Subtract the previous electric meter reading from the current reading, then multiply by the meter multiplier if your bill shows one. The result is the billed kWh for the period.

Convert electric meter readings into kWh and daily usage.
Use this when a bill shows previous and current electric meter reads and you need to understand billed kWh before delivery, fixed fees, and taxes.

Billed usage
685 kWh
685 raw meter units with a 1x multiplier.
Daily kWh
22.1
Billed kWh divided by billing days, useful for comparing two statements.
Energy charge
$123
Estimated from $0.18 per kWh before delivery, fixed charges, and taxes.
Rollover used
No
A rollover is used only when the current read is lower than the previous read.
Electric meter note
Use the multiplier printed on the bill or meter record. Many residential meters use 1x, but some accounts use a higher multiplier.
This estimates the energy portion of the bill. Delivery charges, fixed customer fees, demand charges, taxes, and corrections can still change the final amount.

Short answers for search visitors and bill-checking moments.
What if the current electric meter reading is lower than the previous reading?
That may mean the meter rolled over. Use the meter maximum or rollover value from the meter type, then confirm the read with the utility before relying on the result.
Why does the energy charge differ from the full electric bill?
The energy charge only covers kWh at the rate you entered. Delivery, customer charges, demand charges, riders, taxes, and corrections can make the full bill higher.
