How to work it out

  1. Difference: 54 − 63 = -9
  2. Divide by the starting value: -9 ÷ 63 = -0.142857
  3. Multiply by 100: -14.2857%
  4. Check: Work forwards from the start: 63 × (1 − 0.142857) = 63 × 0.857143 = 54.

In a spreadsheet: =(54-63)/63*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 85.7143% of the old one: for every 100 at the start there are now 85.7143, so 14.2857 out of every 100 have gone.

Sales: a price cut from $63 to $54 is a 14.2857% discount.

Why the change back is different

A 14.2857% fall followed by a 14.2857% rise does not bring you back to 63: it gives 61.7143. The second percentage is taken of 54, not of 63, so to undo this change you need 16.6667% instead.
