How to work it out

  1. Difference: 50 − 10 = 40
  2. Divide by the starting value: 40 ÷ 10 = 4
  3. Multiply by 100: 400%
  4. Check: Work forwards from the start: 10 × (1 + 4) = 10 × 5 = 50.

In a spreadsheet: =(50-10)/10*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 times the old one: for every 100 at the start there are now 500. The value has more than doubled.

Prices: an item whose price rises from $10 to $50 has gone up by 400%.

Why the change back is different

A 400% rise followed by a 400% fall does not bring you back to 10: it gives -150. The second percentage is taken of 50, not of 10, so to undo this change you need 80% instead.
