Net Gaming Revenue

Net gaming revenue (NGR) is a gaming-revenue figure calculated after specified deductions are taken from a gross gaming revenue base. The important word is specified: there is no single universal NGR formula that applies to every casino, regulator, contract, online operator, accounting system, or management report.

In practice, NGR is useful only when the reader knows exactly what has been deducted.

A report might deduct promotional credits, jackpot contributions, gaming taxes, platform fees, payment charges, affiliate costs, or other agreed items. Another report may use a narrower definition and deduct only a few of those items. Two businesses can therefore publish an “NGR” number that is not directly comparable.

NGR starts with a gross gaming revenue base

The usual starting point is some form of gross gaming revenue (GGR), sometimes also called gaming win or casino win in particular contexts.

At a simple table-game level, a gross gaming result can be thought of as:

Gaming win = wagers retained by the casino − gaming payouts to players

For a property or reporting period, the actual accounting definition may include adjustments for items such as jackpots, promotional instruments, progressive liabilities, unredeemed instruments, or game-specific rules. That is why the report definition matters more than the label alone.

NGR then applies an additional layer of deductions.

A generic framework is:

NGR = GGR − defined gaming-related deductions

The phrase “defined gaming-related deductions” must be replaced by the actual list used in the report.

A worked example shows why the deduction list matters

Assume a casino department reports $1,000,000 of GGR for a month.

Its internal NGR report deducts:

• $70,000 of redeemed promotional gaming credits;
• $50,000 of gaming tax allocated to that revenue stream;
• $20,000 of jackpot or progressive contributions charged against the metric;
• $10,000 of platform or game-provider charges included by management in the NGR definition.

Then:

NGR = $1,000,000 − $70,000 − $50,000 − $20,000 − $10,000 = $850,000

That does not mean $850,000 is profit.

The business may still have payroll, utilities, surveillance, security, marketing, rent, depreciation, maintenance, food-and-beverage support, administration, financing costs, and many other expenses. NGR is a filtered gaming-revenue measure, not the bottom line.

NGR is not the same as gross gaming revenue

GGR answers a question close to: How much gaming revenue was produced before the report’s later deductions?

NGR answers: How much of that gaming revenue remains after the specific deductions included in this NGR definition?

That makes NGR more “net” than GGR, but only in relation to those stated deductions.

The exact terminology can differ between land-based casinos, online gaming businesses, regulators, suppliers, and public-company reporting. Always read the metric definition supplied with the number.

Why promotional credits can create confusion

Free play and promotional credits are one of the main reasons people talk past each other when discussing NGR.

Suppose a casino issues $100,000 in promotional slot credits. That does not automatically mean the casino has a $100,000 cash expense in the same way as paying a supplier invoice. The economic cost depends on how the promotion works, how much is redeemed, what game outcomes occur, and how the accounting system treats the instrument.

One management report may deduct the face value of redeemed promotional play from GGR. Another may use a different internal cost treatment. A regulatory report may have its own statutory rules.

So a statement such as “NGR is GGR minus bonuses” is incomplete unless it explains which bonuses, at what value, and under whose definition.

Gaming taxes may be above or below the NGR line

The same caution applies to gaming tax.

Some businesses define NGR after gaming taxes. Others present NGR before gaming taxes and deduct tax elsewhere. Contract formulas between operators, landlords, platform providers, or game suppliers may also define the term differently.

That means the following two formulas can both exist in real reporting environments:

NGR A = GGR − promotions − gaming tax − provider fees

NGR B = GGR − promotions − provider fees

In the second definition, tax is handled later.

Neither formula should be assumed correct outside the document that defines it.

NGR is useful for commercial agreements only when the formula is locked

Revenue-sharing agreements often depend on a net revenue concept. That makes definition discipline essential.

Imagine a game supplier receives 10% of NGR. If the agreement does not define NGR precisely, a major dispute can arise over whether the base should deduct:

• taxes;
• promotional credits;
• jackpots;
• payment processing;
• chargebacks;
• loyalty points;
• third-party commissions;
• bad debt;
• platform costs.

A percentage means little until the base is defined.

For contract analysis, the correct question is not “What does NGR usually mean?” It is “What does this agreement say NGR means?”

NGR can help management compare products, but only consistently

Within one business, a stable NGR definition can be useful for comparing periods, channels, properties, games, or customer segments.

For example, two slot products may generate the same GGR but different NGR because one carries a higher supplier fee or promotional burden. Two markets may have similar gaming win but very different tax structures. A VIP program may increase GGR while also increasing reinvestment.

Those differences are exactly why management may prefer a netted metric for some decisions.

The comparison is meaningful only if the deductions are applied consistently. If the formula changes between periods, the apparent performance change may come from accounting classification rather than from casino operations.

A revenue waterfall makes NGR easier to audit

The most useful way to present NGR internally is often as a waterfall from the gross starting number to the final netted number. Instead of publishing one unexplained figure, the report shows each deduction as a separate line.

For example:

That presentation does two things. First, it lets management see why NGR changed. Second, it allows finance, operations, marketing, and commercial partners to reconcile the number back to the gross base.

A single NGR total cannot show whether a decline came from weaker gaming performance, heavier promotional reinvestment, a tax change, a different supplier mix, or a classification change. A waterfall can.

This distinction matters because the operational response is different in each case. Falling GGR may require a product, traffic, pricing, or service investigation. Higher promotional deductions may be intentional if a campaign is acquiring valuable customers. Higher participation fees may reflect a profitable shift toward leased or revenue-share games. The same lower NGR can therefore represent very different business stories.

The deduction method matters as much as the deduction name

Even when two reports both deduct “promotions,” they may not be measuring the same thing.

One system may deduct face value issued. Another may deduct face value redeemed. Another may calculate an economic or accounting cost after considering redemption behavior and game outcome. Similar differences can occur with loyalty points, jackpots, chargebacks, bad debt, payment costs, or third-party commissions.

That means a strong metric definition should identify not only the category but also the measurement basis.

Compare these statements:

• “NGR deducts promotional credits.”
• “NGR deducts redeemed promotional slot credits at face value during the reporting period.”

The second statement is much more useful because another analyst can reproduce it.

This is a recurring theme in casino reporting: a metric becomes reliable when another competent person can start from the same source data and reach the same result.

NGR per player, per day, or per product needs a denominator too

Management sometimes converts NGR into ratios such as NGR per active player, NGR per occupied room, NGR per gaming day, NGR per machine, or NGR per market segment.

Those ratios can be useful, but the denominator creates another definition problem.

Suppose one report shows NGR per active player. Does “active” mean:

• anyone who made one wager;
• anyone with rated play;
• anyone above a minimum activity threshold;
• unique players during the day;
• unique players during the month?

A change in the active-player definition can move the ratio even when total NGR does not change.

The same problem appears in land-based comparisons. NGR per slot can look stronger simply because a property removed underperforming machines. NGR per table can rise if fewer tables were open. For useful trend analysis, management should pair the revenue definition with a stable denominator and explain major changes in capacity, hours, or customer-count methodology.

NGR is still above contribution margin and operating profit

A netted gaming-revenue figure can feel close to profit because several deductions have already been removed. It is still important to keep the layers separate.

Consider a slot product that produces $100,000 of GGR and $82,000 of NGR after the deductions used in a particular internal report. If that product also requires additional labor, floor space, maintenance, system support, marketing, depreciation, or a capital lease payment not included in the NGR definition, the economic contribution is lower than $82,000.

A management team may therefore use several layers:

GGR → NGR → contribution margin → department operating result → property operating result → accounting profit

Not every casino uses those exact labels, and some businesses place particular costs at different levels. The value lies in keeping the hierarchy explicit.

This prevents a common analytical mistake: calling a product “more profitable” merely because its NGR is higher. Profitability requires the relevant costs below the NGR line too.

Formula changes should be treated like data changes

If management changes the NGR definition, the report should not quietly continue the old time series as though nothing happened.

Suppose a casino historically reported NGR before gaming tax, then begins deducting gaming tax inside NGR. The new number will fall even if customer activity and casino performance are unchanged.

A disciplined report should either:

• restate prior periods under the new definition where practical;
• show both old and new definitions during a transition;
• or mark a clear break in comparability.

The same principle applies if free play moves from an expense line into the NGR calculation, if a supplier fee is reclassified, or if jackpot contributions change accounting treatment.

Metric governance is not paperwork for its own sake. It prevents managers from reacting to an accounting-definition change as if it were an operational performance change.

External NGR comparisons deserve extra skepticism

NGR is often most useful inside one organization, where the formula can be kept stable and reconciled to known systems. It becomes more dangerous when comparing different companies.

Two operators can have identical gambling volume and similar GGR but very different reported NGR because of:

• tax regimes;
• promotional accounting;
• supplier and platform contracts;
• channel mix;
• progressive funding;
• payment costs;
• affiliate or acquisition costs;
• jackpot treatment;
• reporting conventions.

For that reason, an NGR margin such as “NGR equals 78% of GGR” is not automatically better or worse than another company reporting 84%. The analyst first needs to understand what each percentage contains.

The safer comparison is always definition first, number second.

NGR does not replace theoretical loss or player rating

NGR is a business-level revenue measure. It is not a substitute for the operational mathematics used to rate individual play.

A player-rating system may estimate theoretical loss from:

• average bet;
• game house edge or theoretical hold assumption;
• decisions per hour;
• time played.

That produces an estimate of expected casino win from a player’s action. NGR, by contrast, is usually a realized revenue measure after defined deductions at a broader reporting level.

The two can inform the same management conversation, but they answer different questions.

NGR is not net income

This is the most important glossary boundary.

A casino can report strong NGR and still have weak profit if its operating expenses are high. A property can also have lower NGR but better profitability if it controls labor, occupancy, marketing, financing, and other costs more effectively.

Net income belongs much further down the accounting statement.

So the chain should be understood conceptually as:

Wagering volume → gaming revenue → selected net gaming revenue measure → broader operating expenses → accounting profit

The labels and exact ordering vary by organization, but NGR should never be treated as a synonym for final profit unless a specific report explicitly defines it that way.

A safe way to read any NGR number

When you see “NGR,” ask five questions before comparing it with another number:

1. What is the gross starting base?
2. Which deductions are included?
3. Are gaming taxes deducted here or elsewhere?
4. How are promotional credits and jackpots treated?
5. Is this a regulatory, accounting, management, supplier-contract, or marketing definition?

If those answers are missing, the number may still be useful internally, but it should not be assumed comparable with another company’s NGR.
