The only deduction from the donation amount is card processing costs. Virtually all donations are made via credit or debit card, and a 2.9% + $.30 per transaction fee covers the card processing costs charged to us.
If the donor chooses to leave us a tip, that is added on top of the donation amount. The tip can be adjusted to whatever the donor thinks is fair.
Let's say someone wants to donate $100 to a graduation party. They OK a $10 tip so we can continue to run this service. The total credit card charge is $110. Of the $100 that is the donation piece, $96.80 will be deposited in the host's bank account (that's $100 less the 2.9% less the 30¢ credit card fees).
