How to work it out

  1. Difference: 57 − 34 = 23
  2. Divide by the starting value: 23 ÷ 34 = 0.676471
  3. Multiply by 100: 67.6471%
  4. Check: Work forwards from the start: 34 × (1 + 0.676471) = 34 × 1.676471 = 57.

In a spreadsheet: =(57-34)/34*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 1.6765 times the old one: for every 100 at the start there are now 167.6471.

Prices: an item whose price rises from $34 to $57 has gone up by 67.6471%.

Why the change back is different

A 67.6471% rise followed by a 67.6471% fall does not bring you back to 34: it gives 18.4412. The second percentage is taken of 57, not of 34, so to undo this change you need 40.3509% instead.
