How to work it out

  1. Difference: 55 − 82 = -27
  2. Divide by the starting value: -27 ÷ 82 = -0.329268
  3. Multiply by 100: -32.9268%
  4. Check: Work forwards from the start: 82 × (1 − 0.329268) = 82 × 0.670732 = 55.

In a spreadsheet: =(55-82)/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 67.0732% of the old one: for every 100 at the start there are now 67.0732, so 32.9268 out of every 100 have gone.

Sales: a price cut from $82 to $55 is a 32.9268% discount.

Why the change back is different

A 32.9268% fall followed by a 32.9268% rise does not bring you back to 82: it gives 73.1098. The second percentage is taken of 55, not of 82, so to undo this change you need 49.0909% instead.
