Excel offers a convenient built-in formula, "=PERCENTCHANGE", to calculate percentage change. Simply select the cells containing the new and original values, enter the formula in a new cell, and press Enter.
Calculating Percentage Change Manually
If you prefer a manual approach, follow these steps:
- Subtract the original value from the new value to get the change.
- Divide the change by the original value.
- Multiply by 100 to express the result as a percentage.

Negative values indicate a decrease. When calculating percentage change with negative values, make sure to use absolute values to ensure a positive result. For example, if the original value is -10 and the new value is -5, the percentage change calculation should be:
Percentage Change = (|-5| - |-10|) ÷ |-10|
