How to work it out

  1. Difference: 20 − 13 = 7
  2. Divide by the starting value: 7 ÷ 13 = 0.538462
  3. Multiply by 100: 53.8462%
  4. Check: Work forwards from the start: 13 × (1 + 0.538462) = 13 × 1.538462 = 20.

In a spreadsheet: =(20-13)/13*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 1.5385 times the old one: for every 100 at the start there are now 153.8462.

Prices: an item whose price rises from $13 to $20 has gone up by 53.8462%.

Why the change back is different

A 53.8462% rise followed by a 53.8462% fall does not bring you back to 13: it gives 9.2308. The second percentage is taken of 20, not of 13, so to undo this change you need 35% instead.
