From increase amount to percent increase

The starting value is the baseline. If the final value is lower, the same calculation becomes a negative percent change.

Use this when

  • A price rose.
  • A metric grew between two reports.
  • A salary or rate changed.
  • Inventory, traffic, or count values increased.
  • A before-and-after report needs both amount and percent.

FAQ

Why is the starting value the baseline?

Percent increase measures growth relative to where the value began, so the same increase amount can produce different percentages from different starting values.

What happens if the starting value is zero?

The increase amount can still be found, but percent increase is undefined because there is no starting baseline to divide by.
