Start with the accounting identity
Statements come in dozens of layouts and no two PSPs format them the same way. But every statement, whatever it looks like, resolves to one equation: gross volume, minus refunds, minus chargebacks, minus fees, minus reserve, equals net deposit. If you can sort every line on the page into one of those five buckets, you can read any statement — regardless of how the provider chose to lay it out.
Read it in that order, top to bottom. The number you care about isn't any single line — it's how much of your gross volume survives the trip down to the net deposit, and which lines took the biggest bites along the way.
The top line: gross volume
Gross volume (sometimes "gross processed" or "sales") is the total value of approved transactions before anything is deducted. Note the transaction count next to it — that matters as much as the dollar figure, because several fees are charged per transaction, not as a percentage. A statement with high volume but huge transaction count is exposed to per-transaction fees in a way a low-count statement isn't. Gross volume is the denominator everything else gets measured against.
What gets subtracted: refunds and chargebacks
Refunds are money you returned to customers — they come straight off gross. Chargebacks are transactions forcibly reversed by the issuing bank when a customer disputes them, and they almost always carry a separate per-dispute fee on top of the reversed amount. Track both as a ratio of volume, not just absolute numbers: a rising chargeback ratio is what drives your reserve up and your pricing worse, so it's an early-warning line, not just an accounting one.
The fee stack
This is where your real cost lives, and it's rarely one line. It's a stack — and statements vary enormously in how much they itemize versus bundle. The components to hunt for:
- Processing / discount rate (MDR) — the headline percentage the PSP quoted you
- Interchange — the per-transaction cost set by the card networks, varying by card type and geography; passed through line-by-line on interchange++ pricing, hidden inside the blended rate otherwise
- Scheme / assessment fees — the card networks' own charges, applied per transaction
- Per-transaction / authorization fees — a flat charge on every transaction regardless of size
- Gateway fees — a separate per-transaction charge some providers add just to route the transaction
- Cross-border / international fees — applied when the acquiring bank isn't in the same country as the cardholder
- FX / currency conversion spread — when the settlement currency differs from the transaction currency
- Chargeback / dispute fees — a flat fee per chargeback, on top of the reversed amount
- Ancillary fees — PCI, compliance, network access, monthly minimums, regulatory line items
How these appear depends on your pricing model. Blended pricing rolls the whole stack into one combined rate — simpler to read, impossible to audit, and usually more expensive than it looks. Interchange++ itemizes every layer — harder to read at first, but it's the only way to see exactly what each component costs. Whichever you're on, the lesson from what you're really paying to process holds: a low headline rate can hide a high real one once the stack is added up.
The rolling reserve
A rolling reserve is a percentage of your volume — typically 5-10% in high-risk — that the PSP withholds and releases on a delay, often 90-180 days out, to cover chargebacks that might surface after the fact. The critical thing to understand: a reserve is not a fee. It's your money, held. It comes back. But it hits your cashflow hard, and you need to track both the balance being held and the release schedule, because a growing reserve can quietly starve a business that's otherwise profitable on paper.
Watch for discretionary holds or reserve adjustments — unscheduled withholdings triggered by a risk event like a chargeback spike or a sudden volume surge, sitting outside the standard reserve formula. These can appear without much warning and aren't always clearly labeled as distinct from the rolling reserve. If your held balance jumped and the percentage didn't, a discretionary hold is usually why.
The bottom line: net deposit
Net settlement (or net deposit) is what should land in your bank account. But the PSP's stated net and the amount that actually arrives often don't match — and the gap is worth reconciling every single month. The usual causes: settlement batches that cut at a fixed time and straddle the month boundary, reserve withheld this period, intermediate fees like instant-settlement charges or an FX conversion margin booked between the gross and net lines, and bank-side deductions on the receiving end. If PSP-net never equals bank-deposit, one of those four is the reason.
Compute your effective rate
Once you can read the statement, your effective rate is simple arithmetic: total fees — the entire stack, not just the headline line — divided by gross volume. Do it every month. If the result is materially higher than the rate on your contract, the gap is the itemized stack, and that's exactly the part that's negotiable and fixable.
A worked example
Say a month with $1,000,000 in gross processed volume. Reading the statement top to bottom:
- Gross volume → $1,000,000
- Less refunds → −$30,000
- Less chargebacks → −$10,000 (plus per-dispute fees, counted in the stack below)
- Less the full fee stack — processing, interchange, scheme, per-transaction, gateway, cross-border, FX, chargeback fees → −$45,000
- Less rolling reserve, 8% withheld → −$80,000 (your money, released ~120 days later — not a cost)
- Net deposit this period → $835,000
The contract said 3.0%. The fee stack actually totaled $45,000 — an effective 4.5%. The reserve looks like the biggest deduction at $80,000, but it isn't a cost; it comes back. The fees are the cost, and the 1.5-point gap between the headline and the effective rate is the part worth fixing. For a CFD broker or prop firm, if that effective number climbs past 5-8% all-in, you're into overpaying territory.
What to do with what you find
Reading the statement properly tells you three things: your true effective rate, your reserve exposure, and whether your settlements actually reconcile. If the effective rate sits well above the headline, if the reserve is choking cashflow, or if PSP-net never matches your bank deposit — those are all fixable, and the fix is usually structural rather than a renegotiation of one line. Local acquiring, the right PSPs for your category, and cleaner settlement terms are the levers; the full picture is in our high risk payment processing breakdown.
Pull your last statement and run the identity: gross, minus refunds, minus chargebacks, minus fees, minus reserve, equals net. If the fee line surprises you — or the net never matches your bank — it's worth a quick call to work through it.
Key Takeaways
- Every statement resolves to one identity: gross − refunds − chargebacks − fees − reserve = net deposit.
- The fee stack — processing, interchange, scheme, per-transaction, gateway, cross-border, FX, chargeback — is where your real cost hides.
- Blended pricing bundles the stack into one rate; interchange++ itemizes it — itemized is harder to read but possible to audit.
- A rolling reserve (typically 5-10%, held 90-180 days) isn't a fee — it's your money held, but it hits cashflow hard.
- Reconcile the PSP's stated net against your actual bank deposit every month — batch timing, reserve, and intermediate fees cause the gap.
