How to work it out

  1. Difference: 66 − 16 = 50
  2. Divide by the starting value: 50 ÷ 16 = 3.125
  3. Multiply by 100: 312.5%
  4. Check: Work forwards from the start: 16 × (1 + 3.125) = 16 × 4.125 = 66.

In a spreadsheet: =(66-16)/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 4.125 times the old one: for every 100 at the start there are now 412.5. The value has more than doubled.

Prices: an item whose price rises from $16 to $66 has gone up by 312.5%.

Why the change back is different

A 312.5% rise followed by a 312.5% fall does not bring you back to 16: it gives -140.25. The second percentage is taken of 66, not of 16, so to undo this change you need 75.7576% instead.
