How to work it out

  1. Difference: 97 − 89 = 8
  2. Divide by the starting value: 8 ÷ 89 = 0.089888
  3. Multiply by 100: 8.9888%
  4. Check: Work forwards from the start: 89 × (1 + 0.089888) = 89 × 1.089888 = 97.

In a spreadsheet: =(97-89)/89*100. Always divide by the starting value, not the new one. A rise from 40 to 50 is +25%, but the fall from 50 back to 40 is −20%.

What the result means

The new value is 1.0899 times the old one: for every 100 at the start there are now 108.9888.

Prices: an item whose price rises from $89 to $97 has gone up by 8.9888%.

Why the change back is different

A 8.9888% rise followed by a 8.9888% fall does not bring you back to 89: it gives 88.2809. The second percentage is taken of 97, not of 89, so to undo this change you need 8.2474% instead.
