How to work it out

  1. Difference: 91 − 16 = 75
  2. Divide by the starting value: 75 ÷ 16 = 4.6875
  3. Multiply by 100: 468.75%
  4. Check: Work forwards from the start: 16 × (1 + 4.6875) = 16 × 5.6875 = 91.

In a spreadsheet: =(91-16)/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 5.6875 times the old one: for every 100 at the start there are now 568.75. The value has more than doubled.

Prices: an item whose price rises from $16 to $91 has gone up by 468.75%.

Why the change back is different

A 468.75% rise followed by a 468.75% fall does not bring you back to 16: it gives -335.5625. The second percentage is taken of 91, not of 16, so to undo this change you need 82.4176% instead.
