How to work it out

  1. Difference: 25 − 74 = -49
  2. Divide by the starting value: -49 ÷ 74 = -0.662162
  3. Multiply by 100: -66.2162%
  4. Check: Work forwards from the start: 74 × (1 − 0.662162) = 74 × 0.337838 = 25.

In a spreadsheet: =(25-74)/74*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 33.7838% of the old one: for every 100 at the start there are now 33.7838, so 66.2162 out of every 100 have gone.

Sales: a price cut from $74 to $25 is a 66.2162% discount.

Why the change back is different

A 66.2162% fall followed by a 66.2162% rise does not bring you back to 74: it gives 41.5541. The second percentage is taken of 25, not of 74, so to undo this change you need 196% instead.
