How to work it out

  1. Difference: 43 − 23 = 20
  2. Divide by the starting value: 20 ÷ 23 = 0.869565
  3. Multiply by 100: 86.9565%
  4. Check: Work forwards from the start: 23 × (1 + 0.869565) = 23 × 1.869565 = 43.

In a spreadsheet: =(43-23)/23*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 1.8696 times the old one: for every 100 at the start there are now 186.9565.

Prices: an item whose price rises from $23 to $43 has gone up by 86.9565%.

Why the change back is different

A 86.9565% rise followed by a 86.9565% fall does not bring you back to 23: it gives 5.6087. The second percentage is taken of 43, not of 23, so to undo this change you need 46.5116% instead.
