How to work it out

  1. Difference: 68 − 90 = -22
  2. Divide by the starting value: -22 ÷ 90 = -0.244444
  3. Multiply by 100: -24.4444%
  4. Check: Work forwards from the start: 90 × (1 − 0.244444) = 90 × 0.755556 = 68.

In a spreadsheet: =(68-90)/90*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 75.5556% of the old one: for every 100 at the start there are now 75.5556, so 24.4444 out of every 100 have gone.

Sales: a price cut from $90 to $68 is a 24.4444% discount.

Why the change back is different

A 24.4444% fall followed by a 24.4444% rise does not bring you back to 90: it gives 84.6222. The second percentage is taken of 68, not of 90, so to undo this change you need 32.3529% instead.
