How to work it out

  1. Difference: 22 − 4 = 18
  2. Divide by the starting value: 18 ÷ 4 = 4.5
  3. Multiply by 100: 450%
  4. Check: Work forwards from the start: 4 × (1 + 4.5) = 4 × 5.5 = 22.

In a spreadsheet: =(22-4)/4*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 5.5 times the old one: for every 100 at the start there are now 550. The value has more than doubled.

Prices: an item whose price rises from $4 to $22 has gone up by 450%.

Why the change back is different

A 450% rise followed by a 450% fall does not bring you back to 4: it gives -77. The second percentage is taken of 22, not of 4, so to undo this change you need 81.8182% instead.
