How to work it out

  1. Difference: 80 − 93 = -13
  2. Divide by the starting value: -13 ÷ 93 = -0.139785
  3. Multiply by 100: -13.9785%
  4. Check: Work forwards from the start: 93 × (1 − 0.139785) = 93 × 0.860215 = 80.

In a spreadsheet: =(80-93)/93*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 86.0215% of the old one: for every 100 at the start there are now 86.0215, so 13.9785 out of every 100 have gone.

Sales: a price cut from $93 to $80 is a 13.9785% discount.

Why the change back is different

A 13.9785% fall followed by a 13.9785% rise does not bring you back to 93: it gives 91.1828. The second percentage is taken of 80, not of 93, so to undo this change you need 16.25% instead.
