How to work it out

  1. Difference: 79 − 85 = -6
  2. Divide by the starting value: -6 ÷ 85 = -0.070588
  3. Multiply by 100: -7.0588%
  4. Check: Work forwards from the start: 85 × (1 − 0.070588) = 85 × 0.929412 = 79.

In a spreadsheet: =(79-85)/85*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 92.9412% of the old one: for every 100 at the start there are now 92.9412, so 7.0588 out of every 100 have gone.

Sales: a price cut from $85 to $79 is a 7.0588% discount.

Why the change back is different

A 7.0588% fall followed by a 7.0588% rise does not bring you back to 85: it gives 84.5765. The second percentage is taken of 79, not of 85, so to undo this change you need 7.5949% instead.
