How to work it out

  1. Difference: 81 − 27 = 54
  2. Divide by the starting value: 54 ÷ 27 = 2
  3. Multiply by 100: 200%
  4. Check: Work forwards from the start: 27 × (1 + 2) = 27 × 3 = 81.

In a spreadsheet: =(81-27)/27*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 $27 to $81 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 27: it gives -81. The second percentage is taken of 81, not of 27, so to undo this change you need 66.6667% instead.
