A donation has a property almost no retail sale has: the person paying intends every dollar to reach the mission. Processing fees are invisible to the donor, but they come straight out of that intent - and across a year of giving, the difference between well-priced and poorly-priced donation processing is a number a board would notice. Here is where to look.
What non-profits actually pay
A non-profit taking donations by card pays the same three layers any merchant pays: interchange (the card networks' wholesale cost), the processor's markup, and a stack of monthly fees. Two things are specific to non-profits. First, the card networks publish reduced interchange categories for registered charities on many card types - but those lower rates only reach you on pricing that passes interchange through at cost, which is one of several reasons interchange-plus pricing tends to fit non-profits well. Second, donation volume often arrives as card-on-file recurring gifts, and on tiered plans those are exactly the transactions that get downgraded into the expensive bucket.
The platform question
Many organizations take donations through a fundraising platform, and platforms earn their keep: donation pages, donor records, receipts, campaign tools. But read the pricing line carefully - most platforms charge a platform fee on top of payment processing, and the combined cost can run well past what the same volume would cost on a non-profit's own merchant account. The honest framing is that you are buying software and processing together, and you should price them together. For a small organization the bundle often wins. For an established one with steady volume, a merchant account plus simpler tooling frequently keeps meaningfully more of each gift.
The donor-covers-fees checkbox
The now-familiar checkbox asking donors to cover the fees does help - industry estimates suggest a majority of online donors accept it when asked. Two cautions. The percentage the platform asks donors to cover is sometimes set above the actual processing cost, with the difference kept by the platform - worth checking. And the checkbox does not fix expensive underlying processing; it just moves the cost onto your most generous people. Cheaper processing helps the donor and the mission at the same time.
ACH: the cheapest dollars you are not collecting
For recurring monthly giving, a bank-account ACH pull costs a fraction of a card transaction - commonly a flat fee measured in cents rather than a percentage. A donor giving $100 a month by premium rewards card can cost the organization several dollars a month in fees; the same gift by ACH costs pennies. Recurring donors are precisely the people willing to fill in a bank form once. Offering ACH as the default for monthly giving, with card as the fallback, is the single highest-leverage change most non-profits can make to their processing costs.
Recurring giving done right
Monthly giving programs live on stored payment credentials, which makes two boring things important. Ask your processor what a stored-credential transaction costs versus a fresh one. And use an account-updater service so expired cards roll over without the donor lapsing - donor attrition from failed cards is a quiet revenue leak that has nothing to do with generosity. Stored cards also put you squarely inside PCI scope, which is manageable but real - our plain-language guide to PCI compliance for small organizations covers what is actually required.
Events and in-person giving
Galas, walks and community events have their own shape: a burst of card-present transactions a few times a year through a tablet reader or a couple of handheld terminals. Two practical notes. Card-present donations carry lower wholesale costs than online gifts, so a reader at the event is not just convenient - it is the cheapest way that gift can arrive. And ask what idle hardware costs you in the off months: a monthly terminal fee on a reader used twice a year is the kind of small leak that hides in non-profit statements. Some processors will price seasonal hardware sensibly if asked. Asking is free.
