How to work it out

  1. Difference: 56 − 82 = -26
  2. Divide by the starting value: -26 ÷ 82 = -0.317073
  3. Multiply by 100: -31.7073%
  4. Check: Work forwards from the start: 82 × (1 − 0.317073) = 82 × 0.682927 = 56.

In a spreadsheet: =(56-82)/82*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 68.2927% of the old one: for every 100 at the start there are now 68.2927, so 31.7073 out of every 100 have gone.

Sales: a price cut from $82 to $56 is a 31.7073% discount.

Why the change back is different

A 31.7073% fall followed by a 31.7073% rise does not bring you back to 82: it gives 73.7561. The second percentage is taken of 56, not of 82, so to undo this change you need 46.4286% instead.
