How to work it out

  1. Difference: 89 − 85 = 4
  2. Divide by the starting value: 4 ÷ 85 = 0.047059
  3. Multiply by 100: 4.7059%
  4. Check: Work forwards from the start: 85 × (1 + 0.047059) = 85 × 1.047059 = 89.

In a spreadsheet: =(89-85)/85*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 1.0471 times the old one: for every 100 at the start there are now 104.7059.

Prices: an item whose price rises from $85 to $89 has gone up by 4.7059%.

Why the change back is different

A 4.7059% rise followed by a 4.7059% fall does not bring you back to 85: it gives 84.8118. The second percentage is taken of 89, not of 85, so to undo this change you need 4.4944% instead.
