Most conversations about merchant account fees start and end with the acquiring rate — the percentage taken when a customer pays. It’s the number on the homepage, the number in the sales call, the number founders compare across providers before choosing one. What gets far less attention is the other direction: what it costs to send money back out.
For a lot of high-risk business models, outgoing payments aren’t an edge case. A gambling platform pays out winnings. An affiliate program pays commissions. A forex broker processes withdrawal requests from trader accounts. A crypto exchange sends funds back to a customer’s card after a failed order. Every one of those is a card payout — technically called an OCT, Original Credit Transaction — and every one of them carries its own fee, separate from whatever was charged to accept the original payment.
What an OCT / Payout Rate Actually Covers
An OCT is the card network mechanism that lets a business push funds onto a cardholder’s card, rather than pulling funds off it. It’s how instant payouts, refunds-to-card, and mass payouts to affiliates or winners actually move. Card networks price this as its own service, with its own rate — it isn’t bundled into the acquiring fee a business already budgets for.
On Polydirection’s published fee schedule for a crypto business, accepting a card payment in EUR runs 6.0% + €0.50. Paying a customer back out via OCT runs 4.5% + €3.00. Different percentage, different fixed fee, different currency-by-currency breakdown — UAH payouts sit at 4.0% + ₴30, while Russian-issued cards split into local (2.8% + 40₸) and international (3.5% + 400₸) tiers. None of these numbers are interchangeable with the acquiring side, and treating them as roughly the same thing is where a lot of cash flow planning goes wrong.
Why Payouts Aren’t Priced the Same as Acquiring
The logic isn’t arbitrary. Pushing funds onto a card carries different fraud and chargeback risk profiles for the networks and issuing banks than pulling funds off one — a payout can’t be charged back the way a purchase can, but it opens its own set of compliance questions (is this a legitimate payout, or a way to move funds that shouldn’t be moving). High-risk verticals amplify that scrutiny, which is part of why the payout rate sits where it does rather than mirroring the acquiring side one-for-one.
The practical result: a business that only tracks its acquiring percentage is tracking half of its actual card-processing cost. The other half shows up every time money moves the other way.
The Businesses That Feel This the Most: Affiliates, Winnings, Withdrawals
Three patterns show up repeatedly across high-risk verticals:
Gambling and iGaming operators paying out player winnings directly to cards — a payout that happens continuously, not occasionally, and scales with exactly the metric the business wants to grow (active, winning players).
Forex brokers processing trader withdrawal requests — often the single largest source of outgoing card volume on the account, and one that traders watch closely for speed and cost, since a slow or expensive withdrawal is the fastest way to damage trust with an active trading client.
Affiliate and referral programs across crypto and gambling businesses — paying commissions directly to affiliate cards rather than by bank transfer, because it’s faster for the affiliate, but it means every commission run carries the payout rate rather than a flat SEPA fee.
None of these are edge cases. They’re core to how the business operates — which is exactly why the payout rate deserves the same attention as the acquiring rate when a business is budgeting, not an afterthought discovered on the first statement.
Doing the Math on a Realistic Payout Volume
Take a gambling platform paying out €50,000 in winnings to EUR cards in a month. At 4.5% + €3 per transaction, spread across, say, 500 payouts averaging €100 each: that’s €2,250 in percentage fees plus €1,500 in fixed fees — €3,750 total, before touching a single incoming payment’s cost. Scale that to a platform paying out €500,000 a month, and the payout line alone starts rivaling what many businesses assume is their only major processing cost: the acquiring fee on the way in.
This isn’t a criticism of the pricing — payouts are a real, priced service with real underlying costs to the provider. It’s a planning gap. A business that models revenue only against the acquiring rate is going to find its actual margin thinner than projected, purely because the outgoing side wasn’t in the spreadsheet.
Where This Fits Into Planning Cash Flow at Polydirection
The fix isn’t complicated: treat payout rate as its own line item from day one, not something to discover later. Model it against realistic payout volume for the specific business — winnings, withdrawals, commissions, whatever the actual outflow pattern looks like — the same way the acquiring rate gets modeled against expected sales volume.
Polydirection publishes the full payout (OCT) breakdown by currency and card type on the fees page, alongside acquiring rates, decline fees, and chargeback thresholds already covered in earlier posts on this blog. Seeing all four numbers side by side — acquiring, payout, decline, chargeback — is what actually lets a high-risk business plan a realistic cost base, instead of budgeting for half the picture and finding the rest on a statement.
