How to work it out

  1. Difference: 58 − 100 = -42
  2. Divide by the starting value: -42 ÷ 100 = -0.42
  3. Multiply by 100: -42%
  4. Check: Work forwards from the start: 100 × (1 − 0.42) = 100 × 0.58 = 58.

In a spreadsheet: =(58-100)/100*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 58% of the old one: for every 100 at the start there are now 58, so 42 out of every 100 have gone.

Sales: a price cut from $100 to $58 is a 42% discount.

Why the change back is different

A 42% fall followed by a 42% rise does not bring you back to 100: it gives 82.36. The second percentage is taken of 58, not of 100, so to undo this change you need 72.4138% instead.
