How to work it out

  1. Difference: 62 − 81 = -19
  2. Divide by the starting value: -19 ÷ 81 = -0.234568
  3. Multiply by 100: -23.4568%
  4. Check: Work forwards from the start: 81 × (1 − 0.234568) = 81 × 0.765432 = 62.

In a spreadsheet: =(62-81)/81*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 76.5432% of the old one: for every 100 at the start there are now 76.5432, so 23.4568 out of every 100 have gone.

Sales: a price cut from $81 to $62 is a 23.4568% discount.

Why the change back is different

A 23.4568% fall followed by a 23.4568% rise does not bring you back to 81: it gives 76.5432. The second percentage is taken of 62, not of 81, so to undo this change you need 30.6452% instead.
