How to work it out

  1. Difference: 100 − 28 = 72
  2. Divide by the starting value: 72 ÷ 28 = 2.571429
  3. Multiply by 100: 257.1429%
  4. Check: Work forwards from the start: 28 × (1 + 2.571429) = 28 × 3.571429 = 100.

In a spreadsheet: =(100-28)/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 3.5714 times the old one: for every 100 at the start there are now 357.1429. The value has more than doubled.

Prices: an item whose price rises from $28 to $100 has gone up by 257.1429%.

Why the change back is different

A 257.1429% rise followed by a 257.1429% fall does not bring you back to 28: it gives -157.1429. The second percentage is taken of 100, not of 28, so to undo this change you need 72% instead.
