How to work it out

  1. Difference: 42 − 16 = 26
  2. Divide by the starting value: 26 ÷ 16 = 1.625
  3. Multiply by 100: 162.5%
  4. Check: Work forwards from the start: 16 × (1 + 1.625) = 16 × 2.625 = 42.

In a spreadsheet: =(42-16)/16*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 2.625 times the old one: for every 100 at the start there are now 262.5. The value has more than doubled.

Prices: an item whose price rises from $16 to $42 has gone up by 162.5%.

Why the change back is different

A 162.5% rise followed by a 162.5% fall does not bring you back to 16: it gives -26.25. The second percentage is taken of 42, not of 16, so to undo this change you need 61.9048% instead.
