How to work it out

  1. Difference: 78 − 65 = 13
  2. Divide by the starting value: 13 ÷ 65 = 0.2
  3. Multiply by 100: 20%
  4. Check: Work forwards from the start: 65 × (1 + 0.2) = 65 × 1.2 = 78.

In a spreadsheet: =(78-65)/65*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 1.2 times the old one: for every 100 at the start there are now 120.

Prices: an item whose price rises from $65 to $78 has gone up by 20%.

Why the change back is different

A 20% rise followed by a 20% fall does not bring you back to 65: it gives 62.4. The second percentage is taken of 78, not of 65, so to undo this change you need 16.6667% instead.
