How to work it out

  1. Difference: 43 − 34 = 9
  2. Divide by the starting value: 9 ÷ 34 = 0.264706
  3. Multiply by 100: 26.4706%
  4. Check: Work forwards from the start: 34 × (1 + 0.264706) = 34 × 1.264706 = 43.

In a spreadsheet: =(43-34)/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 1.2647 times the old one: for every 100 at the start there are now 126.4706.

Prices: an item whose price rises from $34 to $43 has gone up by 26.4706%.

Why the change back is different

A 26.4706% rise followed by a 26.4706% fall does not bring you back to 34: it gives 31.6176. The second percentage is taken of 43, not of 34, so to undo this change you need 20.9302% instead.
