I know this is more math than Excel, but I thought someone may know the
equation. Once I know the equation, I can do the formula with no problem.

In a PayPal type example, let's say I charge someone $100 for a service and
PayPal charges a 2.9% transaction fee.
That's a total of $102.90.

So how can I determine how much more to charge someone so that after the
percentage fee has been subtracted, I will end up with the desired amount of
$100?

If I charge $102.90, then the transaction fee is now $2.98 and the the
difference is $99.92 (but I need it to be $100, for this example)

Does anyone know of an equation that will determine this regardless of the
initial charge amount?

Thanks.
Paul
