How to work it out

  1. Difference: 31 − 74 = -43
  2. Divide by the starting value: -43 ÷ 74 = -0.581081
  3. Multiply by 100: -58.1081%
  4. Check: Work forwards from the start: 74 × (1 − 0.581081) = 74 × 0.418919 = 31.

In a spreadsheet: =(31-74)/74*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 41.8919% of the old one: for every 100 at the start there are now 41.8919, so 58.1081 out of every 100 have gone.

Sales: a price cut from $74 to $31 is a 58.1081% discount.

Why the change back is different

A 58.1081% fall followed by a 58.1081% rise does not bring you back to 74: it gives 49.0135. The second percentage is taken of 31, not of 74, so to undo this change you need 138.7097% instead.
