How to work it out

  1. Difference: 27 − 16 = 11
  2. Divide by the starting value: 11 ÷ 16 = 0.6875
  3. Multiply by 100: 68.75%
  4. Check: Work forwards from the start: 16 × (1 + 0.6875) = 16 × 1.6875 = 27.

In a spreadsheet: =(27-16)/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 1.6875 times the old one: for every 100 at the start there are now 168.75.

Prices: an item whose price rises from $16 to $27 has gone up by 68.75%.

Why the change back is different

A 68.75% rise followed by a 68.75% fall does not bring you back to 16: it gives 8.4375. The second percentage is taken of 27, not of 16, so to undo this change you need 40.7407% instead.
