How to work it out

  1. Difference: 61 − 90 = -29
  2. Divide by the starting value: -29 ÷ 90 = -0.322222
  3. Multiply by 100: -32.2222%
  4. Check: Work forwards from the start: 90 × (1 − 0.322222) = 90 × 0.677778 = 61.

In a spreadsheet: =(61-90)/90*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 67.7778% of the old one: for every 100 at the start there are now 67.7778, so 32.2222 out of every 100 have gone.

Sales: a price cut from $90 to $61 is a 32.2222% discount.

Why the change back is different

A 32.2222% fall followed by a 32.2222% rise does not bring you back to 90: it gives 80.6556. The second percentage is taken of 61, not of 90, so to undo this change you need 47.541% instead.
