How to work it out

  1. Difference: 75 − 18 = 57
  2. Divide by the starting value: 57 ÷ 18 = 3.166667
  3. Multiply by 100: 316.6667%
  4. Check: Work forwards from the start: 18 × (1 + 3.166667) = 18 × 4.166667 = 75.

In a spreadsheet: =(75-18)/18*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 4.1667 times the old one: for every 100 at the start there are now 416.6667. The value has more than doubled.

Prices: an item whose price rises from $18 to $75 has gone up by 316.6667%.

Why the change back is different

A 316.6667% rise followed by a 316.6667% fall does not bring you back to 18: it gives -162.5. The second percentage is taken of 75, not of 18, so to undo this change you need 76% instead.
