How to work it out

  1. Difference: 74 − 20 = 54
  2. Divide by the starting value: 54 ÷ 20 = 2.7
  3. Multiply by 100: 270%
  4. Check: Work forwards from the start: 20 × (1 + 2.7) = 20 × 3.7 = 74.

In a spreadsheet: =(74-20)/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 3.7 times the old one: for every 100 at the start there are now 370. The value has more than doubled.

Prices: an item whose price rises from $20 to $74 has gone up by 270%.

Why the change back is different

A 270% rise followed by a 270% fall does not bring you back to 20: it gives -125.8. The second percentage is taken of 74, not of 20, so to undo this change you need 72.973% instead.
