How to work it out

  1. Difference: 51 − 52 = -1
  2. Divide by the starting value: -1 ÷ 52 = -0.019231
  3. Multiply by 100: -1.9231%
  4. Check: Work forwards from the start: 52 × (1 − 0.019231) = 52 × 0.980769 = 51.

In a spreadsheet: =(51-52)/52*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 98.0769% of the old one: for every 100 at the start there are now 98.0769, so 1.9231 out of every 100 have gone.

Sales: a price cut from $52 to $51 is a 1.9231% discount.

Why the change back is different

A 1.9231% fall followed by a 1.9231% rise does not bring you back to 52: it gives 51.9808. The second percentage is taken of 51, not of 52, so to undo this change you need 1.9608% instead.
