How to work it out

  1. Difference: 22 − 28 = -6
  2. Divide by the starting value: -6 ÷ 28 = -0.214286
  3. Multiply by 100: -21.4286%
  4. Check: Work forwards from the start: 28 × (1 − 0.214286) = 28 × 0.785714 = 22.

In a spreadsheet: =(22-28)/28*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 78.5714% of the old one: for every 100 at the start there are now 78.5714, so 21.4286 out of every 100 have gone.

Sales: a price cut from $28 to $22 is a 21.4286% discount.

Why the change back is different

A 21.4286% fall followed by a 21.4286% rise does not bring you back to 28: it gives 26.7143. The second percentage is taken of 22, not of 28, so to undo this change you need 27.2727% instead.
