How to work it out

  1. Difference: 31 − 32 = -1
  2. Divide by the starting value: -1 ÷ 32 = -0.03125
  3. Multiply by 100: -3.125%
  4. Check: Work forwards from the start: 32 × (1 − 0.03125) = 32 × 0.96875 = 31.

In a spreadsheet: =(31-32)/32*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 96.875% of the old one: for every 100 at the start there are now 96.875, so 3.125 out of every 100 have gone.

Sales: a price cut from $32 to $31 is a 3.125% discount.

Why the change back is different

A 3.125% fall followed by a 3.125% rise does not bring you back to 32: it gives 31.9688. The second percentage is taken of 31, not of 32, so to undo this change you need 3.2258% instead.
