How to work it out

  1. Difference: 70 − 21 = 49
  2. Divide by the starting value: 49 ÷ 21 = 2.333333
  3. Multiply by 100: 233.3333%
  4. Check: Work forwards from the start: 21 × (1 + 2.333333) = 21 × 3.333333 = 70.

In a spreadsheet: =(70-21)/21*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 3.3333 times the old one: for every 100 at the start there are now 333.3333. The value has more than doubled.

Prices: an item whose price rises from $21 to $70 has gone up by 233.3333%.

Why the change back is different

A 233.3333% rise followed by a 233.3333% fall does not bring you back to 21: it gives -93.3333. The second percentage is taken of 70, not of 21, so to undo this change you need 70% instead.
