How to work it out

  1. Difference: 34 − 54 = -20
  2. Divide by the starting value: -20 ÷ 54 = -0.37037
  3. Multiply by 100: -37.037%
  4. Check: Work forwards from the start: 54 × (1 − 0.37037) = 54 × 0.62963 = 34.

In a spreadsheet: =(34-54)/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 62.963% of the old one: for every 100 at the start there are now 62.963, so 37.037 out of every 100 have gone.

Sales: a price cut from $54 to $34 is a 37.037% discount.

Why the change back is different

A 37.037% fall followed by a 37.037% rise does not bring you back to 54: it gives 46.5926. The second percentage is taken of 34, not of 54, so to undo this change you need 58.8235% instead.
