How to work it out

  1. Difference: 62 − 80 = -18
  2. Divide by the starting value: -18 ÷ 80 = -0.225
  3. Multiply by 100: -22.5%
  4. Check: Work forwards from the start: 80 × (1 − 0.225) = 80 × 0.775 = 62.

In a spreadsheet: =(62-80)/80*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 77.5% of the old one: for every 100 at the start there are now 77.5, so 22.5 out of every 100 have gone.

Sales: a price cut from $80 to $62 is a 22.5% discount.

Why the change back is different

A 22.5% fall followed by a 22.5% rise does not bring you back to 80: it gives 75.95. The second percentage is taken of 62, not of 80, so to undo this change you need 29.0323% instead.
