How to work it out

  1. Difference: 9 − 6 = 3
  2. Divide by the starting value: 3 ÷ 6 = 0.5
  3. Multiply by 100: 50%
  4. Check: Work forwards from the start: 6 × (1 + 0.5) = 6 × 1.5 = 9.

In a spreadsheet: =(9-6)/6*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 1.5 times the old one: for every 100 at the start there are now 150.

Prices: an item whose price rises from $6 to $9 has gone up by 50%.

Why the change back is different

A 50% rise followed by a 50% fall does not bring you back to 6: it gives 4.5. The second percentage is taken of 9, not of 6, so to undo this change you need 33.3333% instead.
