How to work it out

  1. Difference: 70 − 86 = -16
  2. Divide by the starting value: -16 ÷ 86 = -0.186047
  3. Multiply by 100: -18.6047%
  4. Check: Work forwards from the start: 86 × (1 − 0.186047) = 86 × 0.813953 = 70.

In a spreadsheet: =(70-86)/86*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 81.3953% of the old one: for every 100 at the start there are now 81.3953, so 18.6047 out of every 100 have gone.

Sales: a price cut from $86 to $70 is a 18.6047% discount.

Why the change back is different

A 18.6047% fall followed by a 18.6047% rise does not bring you back to 86: it gives 83.0233. The second percentage is taken of 70, not of 86, so to undo this change you need 22.8571% instead.
