How Net Gaming Revenue (NGR) Is Calculated: From Gross Bets to Publisher Commission

Most affiliate commission disputes do not begin with a dispute over the percentage rate. They begin with a disagreement over the base. A publisher contracted at 35% RevShare on a $10,000 GGR month expects $3,500 and receives $1,750 — and the entire gap sits inside the NGR waterfall. This guide deconstructs that waterfall line by line, provides an illustrative calculation model, and sets out a practical audit framework for monthly statements.

Regulatory context matters throughout: gambling regulations, gaming taxes, and affiliate disclosure obligations vary by jurisdiction (UKGC, MGA, Curacao GCB, and others), and every deduction discussed below is subject to the specific operator contract and local legal verification.

1. Gross Gaming Revenue (GGR) Defined: Bets, Wins, and Casino Hold

The Core Formula

Gross Gaming Revenue is the operator’s top-line gaming result before any cost deduction:

For a casino vertical, GGR is sometimes expressed as “casino hold” — the amount retained from player stakes. For sports betting, the equivalent term is “hold” or “margin.” In both cases, GGR is a player-activity metric, not a profitability metric. It says nothing about what the operator spent to acquire the player, what it paid a game studio for the content, or what tax authority took a slice.

Theoretical House Edge vs. Empirical Volatility

Two distinct forces shape GGR, and conflating them is a common source of affiliate misexpectation.

Theoretical house edge is a mathematical property of the game’s rules and paytable. A game with a 96% RTP (return to player) carries a 4% theoretical house edge over an infinite sample. Over 10,000 spins, however, the empirical result can deviate substantially from 4% — variance is a function of bet size, game volatility, and sample size. High-volatility slots can produce negative GGR for an operator over a short window even with a favourable theoretical edge.

Sports betting behaves differently again. Hold is not a fixed property of a market; it emerges from the bookmaker’s pricing, the distribution of stakes across outcomes, and the results themselves. A single weekend of favourites winning can swing a sportsbook’s hold from a healthy margin to a loss.

The practical implication for publishers: monthly GGR is a volatile, high-variance figure, particularly for small player bases. A single high-roller’s session can dominate a statement. This is one reason professional affiliates evaluate performance over rolling three- to six-month windows rather than month-on-month.

Why GGR Is Never the Commission Base

GGR ignores the operator’s direct costs of generating that revenue. Bonuses are funded from GGR. Game provider royalties are charged against GGR. Payment processing, gaming taxes, and platform costs all attach to the same pool. Paying a publisher a percentage of GGR would mean paying commission on money the operator has already committed elsewhere — which is why essentially no standard RevShare deal is structured on GGR.

The commission base is NGR. For a fuller comparison of how the base interacts with deal structure, see our guide to understanding RevShare and CPA models.

2. The NGR Formula: Deconstructing Standard Industry Deductions

The Standard Formula

This is the canonical structure. In practice, contracts vary in how items are grouped — some operators fold provider royalties into a single “platform fee,” others itemise. The formula above reflects the most transparent presentation, and it is the structure a publisher should push for in reporting.

Deconstructing Each Deduction

Bonuses and Player Incentives

Deposit bonuses, free spins, cashback, and reload offers are funded from GGR before NGR is struck. The deduction typically reflects the bonus value granted, though some contracts deduct bonus cost net of wagering contribution or apply a “bonus carryover” mechanism where unused bonus balances roll into the following month.

Audit note: bonus deductions are the single most common source of statement disputes. A promotional push that drives acquisition also inflates the bonus line — and if the affiliate drove the traffic, the affiliate absorbs the deduction. Establish in contract whether bonus deductions are capped, whether they apply to bonuses granted to your referred players only, and how expired or forfeited bonuses are treated.

Game Provider Royalties

Slot and live-dealer content is licensed on revenue-share terms between the operator and the studio. Providers such as NetEnt, Pragmatic Play, and Evolution typically charge a percentage of the revenue generated on their content — the exact rate is commercially negotiated and varies by provider, game, and operator volume. Live casino content in particular carries structurally higher royalty rates than RNG slots, reflecting production costs.

Where a contract presents a blended “platform fee,” this line may bundle provider royalties with the operator’s own platform and software costs. Ask for the split.

Payment Processing Fees

Deposits and withdrawals each carry transaction costs: PSP commissions, chargeback exposure, FX conversion, and — in some markets — local payment-method fees that are materially higher than card processing. Contracts typically deduct a percentage of deposits, of withdrawals, or of both.

Audit note: confirm whether the deduction is calculated on deposit volume, net deposits, or GGR. These produce very different numbers, and the contract language is sometimes ambiguous.

Gaming Taxes

Jurisdictional gaming taxes — most notably point-of-consumption (POC) taxes, where the tax is levied in the player’s jurisdiction rather than the operator’s — are deducted before NGR. Rates vary enormously by market and are subject to change with local legislation. A publisher sending traffic to multiple regulated markets should expect the effective tax deduction to vary by market, and should ask whether the affiliate statement reports tax by market or as a blended figure.

Regulatory note: tax treatment, deduction permissibility, and affiliate disclosure requirements differ across UKGC, MGA, Curacao GCB, and other regimes. Verify the applicable rules for each market with local counsel; nothing in this guide constitutes tax or legal advice.

Admin Fees

The “admin fee” (sometimes “platform fee,” “management fee,” or “operational fee”) is a percentage deducted from GGR to cover the operator’s cost of running the affiliate programme and associated infrastructure. Industry contracts commonly place this in the 15% to 28% of GGR range, though the exact figure is a commercial term and varies by operator, market, and deal size.

Two structural variants exist, and the difference is material:

• Fee on GGR: Admin fee = X% × GGR. Simple, but stacks on top of other deductions.
• Fee on NGR (post-deduction): Admin fee = X% × (GGR − bonuses − taxes − processing). Lower absolute cost to the publisher.

Always confirm which base applies. A 25% admin fee on GGR is a far heavier charge than a 25% admin fee applied after tax and processing deductions.

3. Illustrative Calculation Walkthrough: From $10,000 GGR to Final Net Commission

The following is an illustrative educational scenario only. All percentages and amounts are hypothetical and chosen for arithmetic clarity. Actual deduction structures, rates, and fee bases vary by operator contract, market, and jurisdiction.

The Waterfall

Reading the Waterfall

The headline number a publisher sees in a dashboard is often GGR. The number that determines the payment is the $5,000 NGR line. At an illustrative 35% RevShare, the commission is $1,750 — 17.5% of the original GGR figure.

Sensitivity: Why the Deduction Stack Matters

The same $10,000 GGR produces very different commissions under different illustrative structures:

A 30-percentage-point swing in the deduction stack moves commission by more than 85% on identical player activity. This is why the deduction schedule — not the headline RevShare percentage — is the most commercially significant term in most affiliate contracts.

4. Auditing Your Affiliate Statement: Detecting Discrepancies and Clarifying Deduction Policies

Red Flags in Monthly Reporting

Unitemised lump-sum admin deductions. A single “admin fees” line with no breakdown of provider royalties, platform costs, and programme fees is the most common opacity pattern. It is not necessarily improper — but it is unauditable, and publishers should treat it as a negotiating point.

Bonus deductions that exceed promotional exposure. If your referred players received $1,500 in bonuses but the statement shows a $4,000 bonus deduction, ask for the calculation. Common legitimate explanations include bonus carryover from prior months or bonuses granted to players outside your referral cohort; common illegitimate ones include misallocated promotional costs.

Retroactive adjustments. Negative adjustments applied to prior months — “tax true-up,” “bonus reconciliation,” “provider fee correction” — should always be itemised with the period and basis. A pattern of retroactive deductions is a serious governance concern.

Tax deductions inconsistent with market mix. If your traffic is concentrated in a low-tax market but the blended tax deduction implies a high-tax jurisdiction, request the market-level breakdown.

Commission percentage drift. Verify that the applied RevShare matches the contracted tier. Tiered structures (higher RevShare at higher NGR bands) are a frequent source of quiet underpayment.

Requesting an Itemised Audit

A professional audit request is specific, written, and time-bound. A workable template:

1. State the period and the line items in question — reference the statement date and the specific deduction lines.
2. Request the calculation basis for each line: the rate applied, the base (GGR, NGR, deposits), and the source data.
3. Request market-level splits for tax and processing where multi-market traffic is involved.
4. Request player-cohort attribution for bonus deductions where the figure appears anomalous.
5. Set a response window — 10 to 15 business days is a reasonable professional expectation.
6. Ask for the contract clause governing each deduction, so the calculation can be checked against the agreed terms.

Most reputable affiliate programmes will provide this. A programme that cannot or will not itemise deductions is providing information the publisher needs in order to price the partnership correctly.

Contract Questions to Establish Upfront

Before driving traffic, resolve the following in writing:

• What is the commission base? GGR, NGR, or a defined variant. Get the formula in the contract, not in a marketing page.
• What is the admin fee, and on what base is it calculated? GGR-based and NGR-based admin fees are not comparable.
• Which deductions apply, and at what rates? Bonuses, provider royalties, processing, tax — itemised.
• Are deductions capped? Particularly for bonuses and processing.
• How are negative carryovers handled? Does a negative NGR month roll forward against future commission, and for how long?
• What is the reporting granularity? Market-level, game-level, and player-cohort-level reporting should be specified.
• What is the dispute and audit process? Response windows, escalation, and the governing law.

The BetJadu partnership terms page sets out the portal’s own programme information framework; treat it as a reference structure for the questions above rather than a substitute for reading your specific operator contract.

A Note on Jurisdiction

Deduction permissibility is not purely commercial. Some jurisdictions impose disclosure or fairness requirements on affiliate remuneration structures; others do not. Gaming tax treatment — particularly POC regimes — changes with local legislation and can alter the deduction stack mid-contract. Publishers operating across UKGC, MGA, and Curacao GCB-licensed operators should maintain a market-by-market view of the applicable rules and verify current requirements with local counsel.

Summary

The NGR waterfall is where affiliate economics are actually decided. GGR is a volatile top-line player metric; NGR is the contractual base; and the deduction stack — bonuses, provider royalties, processing, tax, and admin fees — determines what percentage of GGR actually reaches the publisher. A 35% RevShare on a 50%-deduction stack is a 17.5% effective rate on GGR, and the difference between a lean and a heavy stack can exceed 85% of commission on identical activity.

Audit discipline follows directly: demand itemised deductions, verify the base and rate for every line, reconcile tax against market mix, and resolve the deduction schedule in contract before traffic flows. The illustrative figures in this guide are educational only — your contract, your markets, and your local regulatory obligations define the real numbers.
