How to work it out

  1. Difference: 29 − 54 = -25
  2. Divide by the starting value: -25 ÷ 54 = -0.462963
  3. Multiply by 100: -46.2963%
  4. Check: Work forwards from the start: 54 × (1 − 0.462963) = 54 × 0.537037 = 29.

In a spreadsheet: =(29-54)/54*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 53.7037% of the old one: for every 100 at the start there are now 53.7037, so 46.2963 out of every 100 have gone.

Sales: a price cut from $54 to $29 is a 46.2963% discount.

Why the change back is different

A 46.2963% fall followed by a 46.2963% rise does not bring you back to 54: it gives 42.4259. The second percentage is taken of 29, not of 54, so to undo this change you need 86.2069% instead.
