When Donors Cover Processing Costs
Here is how donor paid costs are calculated:
\[P_{total} = \frac{P_{donation} + F_{fixed}}{1  F_{percent}}\]
P_{total}reflects the total amount charged, including the donation and any processing fees.
P_{donation} reflects the original donation amount. So, if a donor chooses to donate $100 and then cover processing fees, the original donation amount is $100.
F_{fixed} reflects the fixed rate with processing online donations (in many cases, this will be 2.9%, as seen in the table above).
F_{percent} reflects the percentage rate with processing online donations (in many cases, this will be $0.30/transaction, as seen in the table above).
So, if we look at the rate of 2.9% + $0.30 per transaction:
To see what the total amount charged (including original donation and processing fees) would be, we would calculate as follows:
\[\mbox{Total Gift Amount} = \frac{\mbox{Original Donation Amount} + 0.30}{0.971}\]
To find only the processing fees the donor chooses to cover, we would calculate as follows:
\[\mbox{Donor Paid Cost} = \frac{\mbox{Original Donation Amount} + 0.30}{0.971}  \mbox{Original Donation Amount}\]
For example: Let's say a donor wants to give $100 and opts to pay costs. We can simply plug in those values.
\[\mbox{Donor Paid Cost} = \frac{$100 + 0.30}{0.971}  $100\]
\[\mbox{Donor Paid Cost} = \frac{$100.30}{0.971}  $100\]
\[\mbox{Donor Paid Cost} = $103.30  $100\]
\[\mbox{Donor Paid Cost} = $3.30\]
Thus:
 The total gift amount is $103.30 (this is all tax deductible!).
 The donor paid an extra $3.30 on top of their $100 donation.
