ELECTRICITY CALCULATOR
Bill change and percentage
Compare an earlier utility bill with a later one.
How this calculation works
Difference = later bill − earlier bill. Percentage change = difference ÷ earlier bill × 100. An earlier bill of zero does not have a defined percentage change. Different billing periods and rates can affect the comparison.
