How to work it out

  1. Difference: 51 − 16 = 35
  2. Divide by the starting value: 35 ÷ 16 = 2.1875
  3. Multiply by 100: 218.75%
  4. Check: Work forwards from the start: 16 × (1 + 2.1875) = 16 × 3.1875 = 51.

In a spreadsheet: =(51-16)/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 3.1875 times the old one: for every 100 at the start there are now 318.75. The value has more than doubled.

Prices: an item whose price rises from $16 to $51 has gone up by 218.75%.

Why the change back is different

A 218.75% rise followed by a 218.75% fall does not bring you back to 16: it gives -60.5625. The second percentage is taken of 51, not of 16, so to undo this change you need 68.6275% instead.
