How to work it out

  1. Difference: 8 − 58 = -50
  2. Divide by the starting value: -50 ÷ 58 = -0.862069
  3. Multiply by 100: -86.2069%
  4. Check: Work forwards from the start: 58 × (1 − 0.862069) = 58 × 0.137931 = 8.

In a spreadsheet: =(8-58)/58*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 13.7931% of the old one: for every 100 at the start there are now 13.7931, so 86.2069 out of every 100 have gone.

Sales: a price cut from $58 to $8 is a 86.2069% discount.

Why the change back is different

A 86.2069% fall followed by a 86.2069% rise does not bring you back to 58: it gives 14.8966. The second percentage is taken of 8, not of 58, so to undo this change you need 625% instead.
