How to work it out

  1. Difference: 87 − 29 = 58
  2. Divide by the starting value: 58 ÷ 29 = 2
  3. Multiply by 100: 200%
  4. Check: Work forwards from the start: 29 × (1 + 2) = 29 × 3 = 87.

In a spreadsheet: =(87-29)/29*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 $29 to $87 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 29: it gives -87. The second percentage is taken of 87, not of 29, so to undo this change you need 66.6667% instead.
