How to work it out

  1. Difference: 45 − 53 = -8
  2. Divide by the starting value: -8 ÷ 53 = -0.150943
  3. Multiply by 100: -15.0943%
  4. Check: Work forwards from the start: 53 × (1 − 0.150943) = 53 × 0.849057 = 45.

In a spreadsheet: =(45-53)/53*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 84.9057% of the old one: for every 100 at the start there are now 84.9057, so 15.0943 out of every 100 have gone.

Sales: a price cut from $53 to $45 is a 15.0943% discount.

Why the change back is different

A 15.0943% fall followed by a 15.0943% rise does not bring you back to 53: it gives 51.7925. The second percentage is taken of 45, not of 53, so to undo this change you need 17.7778% instead.
