Every organization comparing platforms eventually sits with a calculator and discovers that crowdfunding fees are engineered to resist comparison: one platform advertises "free" and monetizes donor tips, another quotes a low platform fee that excludes processing, a third bundles everything into a number that turns out to have asterisks. The fee question deserves a plain-language anatomy — what the possible cost lines ARE, which ones each model actually charges, and what a real campaign nets under each — because the difference between fee models on a $100,000 campaign is real money that belongs to your cause, and because an organization that understands the anatomy can evaluate any platform's pitch in five minutes, including ours.
The four fee lines that exist
Every crowdfunding cost structure is built from four possible lines; naming them dissolves the marketing. The platform fee: what the platform itself charges for existing — the software, the hosting, the tools. Stated as a percentage of funds raised, this is the line platforms compete on loudest. The payment processing line: what moving money through cards actually costs — the processors' cut, typically in the high-2s to low-3s percent plus small per-transaction amounts, charged by the payment infrastructure whether the platform marks it up or passes it through. The tip line: the "optional" donor tip that free-fee platforms live on — defaulted to a suggested percentage at checkout, paid by your donors on top of their gifts, and largely invisible to the organization whose campaign generated it. And the extras line: the paid add-ons (the analytics tier, the branding removal, the support upgrade) that convert a low headline fee into a real total only the year-end statement reveals. Any platform's true cost is the sum across all four — computed on your actual campaign, not their example.
The models, compared honestly
The "free platform" model: 0% platform fee, monetized by donor tips at checkout. The honest analysis: your organization pays little, your donors pay instead — tips commonly land in the several-percent range of gifts — and the checkout experience works for the platform's revenue, not your campaign's completion. Whether that trade suits you is a real question; that it IS a trade is not. The low-fee-plus model: a modest platform fee that excludes processing and gates real features behind tiers — the model where the calculator matters most, because the advertised number is the floor of a ladder. The all-in percentage model: one number covering everything — simplest to compare, and honest exactly as far as the number is real. And ChaiRaiser's model, stated the way we state it on every page: a 2.9% platform fee, no tips engineered into anyone's checkout, no surprises — and in pledge mode, the structural difference that changes the whole conversation: pledged money moves on your organization's own rails (your existing account, your existing processing relationships, per the pledge-mode mechanics), so the processing line belongs to arrangements you already have and control. Card processing, where campaigns enable it, is at cost. The fee terms live in plain sight on the platform; this article is the anatomy, and the campaign pages are the contract.
A fee model is a statement about whose side the checkout is on. Read every platform's checkout as a donor once — where the flow works hardest for a tip, you've found who the real customer is.
Running the real comparison
The five-minute diligence any organization should run on any platform, ours included. Compute the all-in on your last campaign's real numbers: take your actual raised total and gift count, apply each platform's full stack (platform fee + processing as charged + realistic tip take + the add-ons you'd actually need), and compare nets — not headlines. Check what the donor sees: run a test gift on each platform and watch the checkout — the tip defaults, the upsells, the extra screens; your donors' experience is part of the price, per the completion-friction math. Ask the year-three question: fees compound across an annual calendar — the platform relationship is infrastructure, and infrastructure pricing per the platform-choice framework should be legible enough for a board to re-explain annually. And weigh the fee against the toolset honestly: a fee differential of a point matters far less than the tools' effect on the total — the wheel that lifts average gifts, the follow-up rail that recovers the pledge decay, the games that recruit the second ring. The cheapest platform that raises less was the expensive one.
What fees fund — the question behind the question
The mature version of the fee conversation is not "how low" but "funding what." A platform fee pays for the infrastructure's existence: the engineering, the hosting, the receipts, the support line your treasurer calls, the update and reminder rails that recover real money. The honest tests of whether a fee is earning itself: the tools demonstrably lift totals (measure your own before-and-after), the fee is disclosed where donors can see it (opacity is a price too — the kiddush question "what does the platform take?" should have a one-sentence answer), and the model's incentives point at your success (a platform earning a flat percentage of funds raised wins when you win; a platform earning tips wins when checkouts convert tips — alignment is architecture). The 2.9% number was chosen to be sayable at a board meeting and checkable on a receipt; whatever platform you choose, hold it to exactly that standard.
Frequently asked questions
Is 2.9% the whole cost of running a ChaiRaiser campaign?
The platform fee is 2.9%, stated on every campaign page, with no tip lines added to your donors' checkout. In pledge mode, money moves on your own existing rails under your own arrangements; where card processing is enabled, it's at cost. The fee terms page carries the specifics — and the campaign page links it, because that's where fee terms belong.
Are donor tips really a fee if they're optional?
They're a cost of the campaign borne by your donors — voluntary individually, structural in aggregate, since the checkout is engineered around the suggestion. Count them in any honest comparison: money your community pays because your campaign ran is part of your campaign's price, whoever's line it lands on.
How should we present fees to our own donors?
Plainly and once: the fee line on the campaign page does the work ("2.9% platform fee — no tips, no surprises"), and the copy guide's trust-furniture principle applies — disclosed costs read as competence. Organizations that hide fee questions train donors to wonder; the one-sentence answer trains them to trust.
Do fees change for very large campaigns?
The structural answer beats any private arrangement: a flat, published percentage means the arithmetic scales legibly at every size, which is what boards and auditors actually want. Platforms that negotiate secret tiers are pricing opacity into your books — ask instead what the published model is, and hold everyone to theirs.
