How to work it out

  1. Difference: 90 − 28 = 62
  2. Divide by the starting value: 62 ÷ 28 = 2.214286
  3. Multiply by 100: 221.4286%
  4. Check: Work forwards from the start: 28 × (1 + 2.214286) = 28 × 3.214286 = 90.

In a spreadsheet: =(90-28)/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 3.2143 times the old one: for every 100 at the start there are now 321.4286. The value has more than doubled.

Prices: an item whose price rises from $28 to $90 has gone up by 221.4286%.

Why the change back is different

A 221.4286% rise followed by a 221.4286% fall does not bring you back to 28: it gives -109.2857. The second percentage is taken of 90, not of 28, so to undo this change you need 68.8889% instead.
