How to work it out

  1. Difference: 54 − 71 = -17
  2. Divide by the starting value: -17 ÷ 71 = -0.239437
  3. Multiply by 100: -23.9437%
  4. Check: Work forwards from the start: 71 × (1 − 0.239437) = 71 × 0.760563 = 54.

In a spreadsheet: =(54-71)/71*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 76.0563% of the old one: for every 100 at the start there are now 76.0563, so 23.9437 out of every 100 have gone.

Sales: a price cut from $71 to $54 is a 23.9437% discount.

Why the change back is different

A 23.9437% fall followed by a 23.9437% rise does not bring you back to 71: it gives 66.9296. The second percentage is taken of 54, not of 71, so to undo this change you need 31.4815% instead.
