How to work it out

  1. Difference: 58 − 80 = -22
  2. Divide by the starting value: -22 ÷ 80 = -0.275
  3. Multiply by 100: -27.5%
  4. Check: Work forwards from the start: 80 × (1 − 0.275) = 80 × 0.725 = 58.

In a spreadsheet: =(58-80)/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 72.5% of the old one: for every 100 at the start there are now 72.5, so 27.5 out of every 100 have gone.

Sales: a price cut from $80 to $58 is a 27.5% discount.

Why the change back is different

A 27.5% fall followed by a 27.5% rise does not bring you back to 80: it gives 73.95. The second percentage is taken of 58, not of 80, so to undo this change you need 37.931% instead.
