Based on a specific number, how to I work out the % increase required, using the % decrease which will be applied, to get back to that number?


Example:

$100 is the base number, but a deduction of 9% will be applied.

How do I calculate the % increase required from $100, in order to deduct 9% and get back to $100? I am looking for the calculation not the answer, as the % deducted will be variable.

I am using excel and would prefer in an excel formula if possible, but not necessary, the calculation to find the increase % is enough. thanks
