How to work it out

  1. Difference: 12 − 50 = -38
  2. Divide by the starting value: -38 ÷ 50 = -0.76
  3. Multiply by 100: -76%
  4. Check: Work forwards from the start: 50 × (1 − 0.76) = 50 × 0.24 = 12.

In a spreadsheet: =(12-50)/50*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 24% of the old one: for every 100 at the start there are now 24, so 76 out of every 100 have gone.

Sales: a price cut from $50 to $12 is a 76% discount.

Why the change back is different

A 76% fall followed by a 76% rise does not bring you back to 50: it gives 21.12. The second percentage is taken of 12, not of 50, so to undo this change you need 316.6667% instead.
