The Fine Print That Decides Your iGaming Payout: NGR Deductions, Tiered RevShare, and Flat-Fee Deals

CPA vs RevShare is the easy part. The terms that actually move your payout — NGR deductions, tiered RevShare math, flat-fee placements — are buried further down the contract.

Most affiliates running iGaming traffic can recite CPA vs RevShare vs hybrid in their sleep — we broke that down in detail here, including the break-even math between a flat payout and a lifetime share. That part of the contract is rarely where the real disagreement happens.

The disagreement happens further down the page: what counts as revenue before your percentage applies, what happens after a losing month, how a “tier” actually gets calculated, and whether a placement fee is doing more work than it looks like. Those four terms decide what you actually get paid — and they’re the parts most affiliates skim past.

NGR: the number your RevShare percentage applies to

Nobody pays RevShare on deposits. A deposit just funds a player’s balance — it isn’t revenue yet. Operators pay on net gaming revenue (NGR): stakes minus player winnings, minus whatever the contract defines as deductions before your percentage applies.

That deduction list is the part worth reading twice. A typical iGaming NGR definition subtracts some combination of:

• Bonuses and free-play credits issued to the player
• Gaming duty or betting tax, where the operator passes it through
• Payment processing fees on deposits and withdrawals
• Chargebacks and failed payments

None of that is unusual — every serious operator deducts something. The problem is that two operators offering the “same” 30% RevShare can pay very differently if one deducts gaming tax and the other doesn’t.

Worked example. A cohort of your referred players generates $40,000 in gross gaming revenue this month. The contract deducts $9,000 in bonus cost and $2,000 in processing fees and chargebacks, leaving $29,000 in commissionable NGR. At 30% RevShare, you’re paid $8,700 — not 30% of $40,000.

Ask for the deduction list in writing, by name, before you sign. “Standard deductions apply” is not a deduction list.

No negative carryover: the clause that decides if a bad month follows you

Players lose, but they also sometimes win big — and a big win can push a cohort’s NGR negative for the month. What happens next depends entirely on one clause.

With negative carryover, that negative balance rolls into next month’s calculation before your percentage applies. With no negative carryover (NNC), each month resets — a loss doesn’t follow you into the next period.

Worked example. Your cohort runs a $4,000 negative NGR month after a big payout, followed by a $10,000 positive month. With carryover, next month’s base is $10,000 minus $4,000 = $6,000, and at 30% you’re paid $1,800. With NNC, the negative month is absorbed by the operator and you’re paid 30% of the full $10,000 — $3,000. Same players, same two months, a $1,200 difference.

Some contracts carry a separate exception for one player’s individual big win, carried only against that player’s future activity rather than the whole cohort. If your agreement has that carve-out, get it described in writing — “negative carryover” and “no negative carryover” alone don’t tell you whether it exists.

Tiered RevShare: marginal vs. whole-period is a different payout

Tiered RevShare raises your percentage once a cohort crosses a volume or revenue threshold. The part that trips people up isn’t the threshold — it’s how the higher rate applies once you cross it.

Marginal calculation pays the lower rate up to the threshold and the higher rate only on the amount above it. Whole-period calculation applies the new, higher rate to the entire month’s NGR, not just the portion above the line.

Worked example. Your tier schedule steps from 28% to 34% at $15,000 monthly NGR. Your cohort lands at $18,000 this month.

That’s a $900 gap on the same month, purely from how the tier is written. Whole-period math is more generous to you when you’re just above a threshold — but it also means a strong month on an existing cohort can swing operator cost more than they expect, which is exactly why some contracts quietly default to marginal unless you push back.

Ask three things before you sign a tiered deal: which calculation applies, whether the threshold counts all FTDs or only qualified ones, and whether a later chargeback that drops you back under the line retroactively lowers the rate you already earned.

Flat-fee placements: paying for exposure, not acquisition

A flat fee pays for a specific piece of inventory — a banner slot, a newsletter placement, a sponsored page — for an agreed period, independent of how many players it converts. It’s a different animal from CPA: CPA pays per qualified player, a flat fee pays for the placement whether or not anyone converts.

Flat fees show up most often stacked on top of CPA or RevShare, not instead of it — an operator pays for guaranteed visibility and a per-acquisition rate on whatever that visibility produces.

Worked example. A $2,500 newsletter placement produces 18 qualified signups over the campaign. On its own, that’s $138.89 per qualified signup — a number that moves a lot if the campaign underperforms. Layer in a $70 CPA on those same 18 signups ($1,260) and the blended cost is $3,760 across 18 signups, or $208.89 per qualified player, before the operator’s own downstream costs.

The number that matters here isn’t the sticker price of the placement — it’s cost-per-qualified-player once you divide by actual results, which is why flat-fee deals need the same tracking discipline as CPA, not less.

What CPA and RevShare actually look like by GEO tier in 2026

Headline rates get quoted without context constantly, so here’s roughly where they land this year, drawn from current industry benchmark data rather than any single operator’s rate card:

The pattern worth noticing: CPA moves hard by GEO because it’s priced against expected player value in that market. RevShare barely moves by GEO at all — operators adjust the NGR definition and deductions by market far more than they adjust the headline percentage. If two GEOs quote you the same RevShare rate, the deduction list is where the real difference will show up.

Sportsbook CPA typically prices 20–30% below casino CPA in the same GEO, and crypto casino CPA runs another 30–50% below fiat casino — both reflect shorter or less predictable player lifetime value rather than lower demand.

Five lines to get in writing before you sign

1. The full NGR deduction list, by name — not “standard deductions.”

2. Negative carryover or NNC, stated explicitly, plus whether any individual-player exception exists.

3. Marginal or whole-period for any tiered rate, with a worked example from the operator.

4. What a validated flat-fee placement actually requires to count as delivered, and what happens if the inventory underperforms.

5. How a later chargeback or revenue correction affects a rate you already earned — retroactive or not.

None of this replaces knowing when to pick CPA, RevShare, or hybrid in the first place — that decision framework is here. This is the layer underneath it: the terms that decide whether the rate on the page is the rate you actually collect.
