How to work it out

  1. Difference: 70 − 1 = 69
  2. Divide by the starting value: 69 ÷ 1 = 69
  3. Multiply by 100: 6,900%
  4. Check: Work forwards from the start: 1 × (1 + 69) = 1 × 70 = 70.

In a spreadsheet: =(70-1)/1*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 70 times the old one: for every 100 at the start there are now 7,000. The value has more than doubled.

Prices: an item whose price rises from $1 to $70 has gone up by 6,900%.

Why the change back is different

A 6,900% rise followed by a 6,900% fall does not bring you back to 1: it gives -4,760. The second percentage is taken of 70, not of 1, so to undo this change you need 98.5714% instead.
