How to work it out

  1. Difference: 28 − 12 = 16
  2. Divide by the starting value: 16 ÷ 12 = 1.333333
  3. Multiply by 100: 133.3333%
  4. Check: Work forwards from the start: 12 × (1 + 1.333333) = 12 × 2.333333 = 28.

In a spreadsheet: =(28-12)/12*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 2.3333 times the old one: for every 100 at the start there are now 233.3333. The value has more than doubled.

Prices: an item whose price rises from $12 to $28 has gone up by 133.3333%.

Why the change back is different

A 133.3333% rise followed by a 133.3333% fall does not bring you back to 12: it gives -9.3333. The second percentage is taken of 28, not of 12, so to undo this change you need 57.1429% instead.
