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. In our case, we can stop when rounding to the nearest cent doesn't affect the amount. Here's an example with an adminstrative fee of 10% and an amount of $10,000 for easy math.
| 10% | $ 10,000.00 | $ 1,000.00000 |
| 10% | $ 1,000.00 | $ 100.00000 |
| 10% | $ 100.00 | $ 10.00000 |
| 10% | $ 10.00 | $ 1.00000 |
| 10% | $ 1.00 | $ 0.10000 |
| 10% | $ 0.10 | $ 0.01000 |
| 10% | $ 0.01 | $ 0.00100 |
| 10% | $ 0.00 | $ 0.00010 |
| 10% | $ 0.00 | $ 0.00001 |
| $ 1,111.11111 | ||
| $ 1,111.11 |

Rest assured; this seemingly odd calculation is only there to make sure that the support goal has staff raise enough funds to cover the fee. It is not a hard amount being charged. The account will only ever actually be charged the 10% on what actually comes in. |
| Note |

Some programs have a minimum administrative fee. If you enter a salary of $1, and you still see an administrative fee that is a nice round number, like $250. This is likely your program's minimum administrative fee. |
