How to work it out

  1. Difference: 51 − 17 = 34
  2. Divide by the starting value: 34 ÷ 17 = 2
  3. Multiply by 100: 200%
  4. Check: Work forwards from the start: 17 × (1 + 2) = 17 × 3 = 51.

In a spreadsheet: =(51-17)/17*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 $17 to $51 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 17: it gives -51. The second percentage is taken of 51, not of 17, so to undo this change you need 66.6667% instead.
