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.
When a U.S. supporter gives $100 to a mission through its online donation page, the organization doesn't receive $100. A card processing fee comes out first — and how that fee is structured decides whether the mission keeps $97, or $96, or less. Across thousands of gifts a year, that structure quietly adds up to real money.
There are three common ways card fees are 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.
Why does this matter for a mission specifically? Because recurring gifts are your lifeblood, and they run at high volume. Consider a mission with 500 monthly donors giving an average of $40 — roughly $240,000 in card volume a year. The gap between an opaque blended rate and transparent interchange-plus can easily be a few tenths of a percent, which is somewhere around $700 to $1,200 a year returned to the field — plus, for the first time, the ability to see exactly what you're paying and to verify you're getting any reduced nonprofit rates the networks 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.
