How it works
Compare the change against the starting value
Percentage increase measures growth relative to where you started. The original value is the baseline.
Percentage increase formula
((new value - original value) ÷ original value) × 100
Find the absolute change, divide it by the original value, then multiply by 100.
Percentage increase formula in Excel
Enter =(C2-B2)/B2 when B2 contains the original value and C2 contains the new value. See more examples in the Excel percentage formula guide.
Worked example
