How to work it out

  1. Difference: 81 − 28 = 53
  2. Divide by the starting value: 53 ÷ 28 = 1.892857
  3. Multiply by 100: 189.2857%
  4. Check: Work forwards from the start: 28 × (1 + 1.892857) = 28 × 2.892857 = 81.

In a spreadsheet: =(81-28)/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 2.8929 times the old one: for every 100 at the start there are now 289.2857. The value has more than doubled.

Prices: an item whose price rises from $28 to $81 has gone up by 189.2857%.

Why the change back is different

A 189.2857% rise followed by a 189.2857% fall does not bring you back to 28: it gives -72.3214. The second percentage is taken of 81, not of 28, so to undo this change you need 65.4321% instead.
