How to work it out

  1. Difference: 28 − 97 = -69
  2. Divide by the starting value: -69 ÷ 97 = -0.71134
  3. Multiply by 100: -71.134%
  4. Check: Work forwards from the start: 97 × (1 − 0.71134) = 97 × 0.28866 = 28.

In a spreadsheet: =(28-97)/97*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 28.866% of the old one: for every 100 at the start there are now 28.866, so 71.134 out of every 100 have gone.

Sales: a price cut from $97 to $28 is a 71.134% discount.

Why the change back is different

A 71.134% fall followed by a 71.134% rise does not bring you back to 97: it gives 47.9175. The second percentage is taken of 28, not of 97, so to undo this change you need 246.4286% instead.
