How to work it out

  1. Difference: 45 − 12 = 33
  2. Divide by the starting value: 33 ÷ 12 = 2.75
  3. Multiply by 100: 275%
  4. Check: Work forwards from the start: 12 × (1 + 2.75) = 12 × 3.75 = 45.

In a spreadsheet: =(45-12)/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 3.75 times the old one: for every 100 at the start there are now 375. The value has more than doubled.

Prices: an item whose price rises from $12 to $45 has gone up by 275%.

Why the change back is different

A 275% rise followed by a 275% fall does not bring you back to 12: it gives -78.75. The second percentage is taken of 45, not of 12, so to undo this change you need 73.3333% instead.
