How to work it out

  1. Difference: 75 − 99 = -24
  2. Divide by the starting value: -24 ÷ 99 = -0.242424
  3. Multiply by 100: -24.2424%
  4. Check: Work forwards from the start: 99 × (1 − 0.242424) = 99 × 0.757576 = 75.

In a spreadsheet: =(75-99)/99*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 75.7576% of the old one: for every 100 at the start there are now 75.7576, so 24.2424 out of every 100 have gone.

Sales: a price cut from $99 to $75 is a 24.2424% discount.

Why the change back is different

A 24.2424% fall followed by a 24.2424% rise does not bring you back to 99: it gives 93.1818. The second percentage is taken of 75, not of 99, so to undo this change you need 32% instead.
