How to work it out

  1. Difference: 20 − 74 = -54
  2. Divide by the starting value: -54 ÷ 74 = -0.72973
  3. Multiply by 100: -72.973%
  4. Check: Work forwards from the start: 74 × (1 − 0.72973) = 74 × 0.27027 = 20.

In a spreadsheet: =(20-74)/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 27.027% of the old one: for every 100 at the start there are now 27.027, so 72.973 out of every 100 have gone.

Sales: a price cut from $74 to $20 is a 72.973% discount.

Why the change back is different

A 72.973% fall followed by a 72.973% rise does not bring you back to 74: it gives 34.5946. The second percentage is taken of 20, not of 74, so to undo this change you need 270% instead.
