How to work it out

  1. Difference: 85 − 89 = -4
  2. Divide by the starting value: -4 ÷ 89 = -0.044944
  3. Multiply by 100: -4.4944%
  4. Check: Work forwards from the start: 89 × (1 − 0.044944) = 89 × 0.955056 = 85.

In a spreadsheet: =(85-89)/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 95.5056% of the old one: for every 100 at the start there are now 95.5056, so 4.4944 out of every 100 have gone.

Sales: a price cut from $89 to $85 is a 4.4944% discount.

Why the change back is different

A 4.4944% fall followed by a 4.4944% rise does not bring you back to 89: it gives 88.8202. The second percentage is taken of 85, not of 89, so to undo this change you need 4.7059% instead.
