Some of the calculations for Support Goals are quite complex. This page exists to explain some of them.
We'll start by saying that Reliant has different administrative fees for different programs. We will choose a fee of 10% for easy math. The amount of the administrative fee in the support goal will in fact more than 10%. This because the goal needs to account for the fee itself.
This type of calculation is called a geometric series. The fee is added to the goal, which in turn means a little more funds need to be raised, which makes the goal a tiny bit higher, which requires even a tiny bit more etc. It theoretically runs on infinitely, but as you go further the amounts get smaller and smaller up until you reach a negligible amount being added.
Rest assured; this seemingly odd calculation is only there to make sure that the support goal has them raise enough funds to cover the fee. It is not a hard amount being charged. The account they’re responsible will only ever actually be charged the 10% on what actually comes in.
