How to work it out

  1. Difference: 45 − 15 = 30
  2. Divide by the starting value: 30 ÷ 15 = 2
  3. Multiply by 100: 200%
  4. Check: Work forwards from the start: 15 × (1 + 2) = 15 × 3 = 45.

In a spreadsheet: =(45-15)/15*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 times the old one: for every 100 at the start there are now 300. The value has more than doubled.

Prices: an item whose price rises from $15 to $45 has gone up by 200%.

Why the change back is different

A 200% rise followed by a 200% fall does not bring you back to 15: it gives -45. The second percentage is taken of 45, not of 15, so to undo this change you need 66.6667% instead.
