How do I calculate a negative percentage in Excel?

Entering =ABS(-100) into cell A1 would return 100. The ABS function essentially makes any number a non-negative number. Using ABS in this formula negates the effect of the negative benchmark (the negative 10,000 budget in the example) and returns the correct percent variance.

Can you have a negative percentage?

Answer: If the experimental value is less than the accepted value, then the percent error is negative. Generally, the error is calculated as the measure of the absolute difference to avoid the confusion of a negative error.

How do you calculate negative CAGR?

4. Press “Enter.” Excel calculates the new value and displays it in the cell.

Are percent errors negative?
