How to work it out

  1. Difference: 77 − 16 = 61
  2. Divide by the starting value: 61 ÷ 16 = 3.8125
  3. Multiply by 100: 381.25%
  4. Check: Work forwards from the start: 16 × (1 + 3.8125) = 16 × 4.8125 = 77.

In a spreadsheet: =(77-16)/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 4.8125 times the old one: for every 100 at the start there are now 481.25. The value has more than doubled.

Prices: an item whose price rises from $16 to $77 has gone up by 381.25%.

Why the change back is different

A 381.25% rise followed by a 381.25% fall does not bring you back to 16: it gives -216.5625. The second percentage is taken of 77, not of 16, so to undo this change you need 79.2208% instead.
