How to work it out

  1. Difference: 77 − 20 = 57
  2. Divide by the starting value: 57 ÷ 20 = 2.85
  3. Multiply by 100: 285%
  4. Check: Work forwards from the start: 20 × (1 + 2.85) = 20 × 3.85 = 77.

In a spreadsheet: =(77-20)/20*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 3.85 times the old one: for every 100 at the start there are now 385. The value has more than doubled.

Prices: an item whose price rises from $20 to $77 has gone up by 285%.

Why the change back is different

A 285% rise followed by a 285% fall does not bring you back to 20: it gives -142.45. The second percentage is taken of 77, not of 20, so to undo this change you need 74.026% instead.
