How to work it out

  1. Difference: 54 − 12 = 42
  2. Divide by the starting value: 42 ÷ 12 = 3.5
  3. Multiply by 100: 350%
  4. Check: Work forwards from the start: 12 × (1 + 3.5) = 12 × 4.5 = 54.

In a spreadsheet: =(54-12)/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 4.5 times the old one: for every 100 at the start there are now 450. The value has more than doubled.

Prices: an item whose price rises from $12 to $54 has gone up by 350%.

Why the change back is different

A 350% rise followed by a 350% fall does not bring you back to 12: it gives -135. The second percentage is taken of 54, not of 12, so to undo this change you need 77.7778% instead.
