The quiet leak in online giving: card processing fees, explained
Every online card donation loses a slice to processing fees — and much of that slice is negotiable. Here's how interchange-plus pricing works, and why it matters for missions.
Every card gift arrives a little smaller than it left.
The scenario
December is when Daniel, who runs operations at a small church-planting nonprofit, likes to look at the giving numbers. Online gifts came in at $52,000 across about 1,300 donations — the best month they’d ever had. Then the bank deposits landed at $50,600, and the $1,400 gap just sat there.
Most of it was the percentage fee everyone expects. But a good chunk was quieter: a flat $0.30 charged on every one of those 1,300 gifts — nearly $400 on its own, before a single percent was counted. Daniel had always filed card fees under “the price of taking donations online.” He’d never noticed the price punished his smallest, most frequent gifts the hardest.
“2.9% + $0.30” per gift
The smaller the gift, the bigger the bite
The headline “2.9%” hides a flat $0.30 on every transaction. On a $10 gift that $0.30 alone is 3% — so your smallest, most frequent gifts lose nearly 6% before they reach you.
Almost every processor quotes the same shape: a percentage plus a flat per-transaction fee — commonly around “2.9% + $0.30.” The percentage is what everyone notices. The flat $0.30 is what quietly does the damage, because it doesn’t shrink with the gift. On a $100 donation it’s a rounding error; on a $10 donation it’s a 3% surcharge all by itself. For a mission whose lifeblood is small, recurring gifts, that’s exactly the wrong fee in exactly the wrong place.
Beyond that flat fee, there are three common ways the percentage is priced, and they are not equally transparent.
Flat rate. One blended percentage on every transaction — simple and predictable, but usually the most expensive over time, because the provider builds a comfortable cushion into that single number.
Tiered. Transactions get sorted into “qualified,” “mid-qualified,” and “non-qualified” buckets, each priced differently. It looks detailed, but you rarely control which bucket a donation lands in, and the logic is opaque by design.
Interchange-plus. The clearest of the three. The card networks set a base cost — the “interchange” — for every transaction. A transparent processor passes that exact cost through and adds a small, disclosed markup on top. Nothing is blended or hidden, and every statement itemizes interchange, network fees, and markup as separate lines.
Put real numbers on it. A mission with 500 recurring donors giving $40 a month processes 6,000 gifts and about $240,000 a year. At “2.9% + $0.30,” that’s roughly $6,960 in percentage fees plus $1,800 in flat per-gift fees — $8,760 a year, an effective 3.65%. The $1,800 flat portion bought nothing, and on its own could have funded a field worker for a month. Move to transparent interchange-plus pricing and much of that gap comes back — and, for the first time, you can see exactly what you’re paying and verify the reduced nonprofit rates the networks actually offer.
The takeaway: ask your processor one direct question — Am I on flat-rate, tiered, or interchange-plus pricing? — and ask to see interchange and markup itemized separately on your statement. If they can't or won't show you, that's your answer.
A flat $0.30 sounds harmless — until you’re paying it on every $10 gift, thousands of times a month.
