GGR (Gross Gaming Revenue)
Gross Gaming Revenue
Definition
Total player stakes minus player winnings. The headline revenue figure for operators and the basis for many regulatory frameworks and taxes.
Key takeaways
- Gross gaming revenue (GGR) is the amount an operator keeps after paying out player winnings, but before any costs, bonuses or duty.
- GGR is the industry’s headline revenue measure and the base most gambling tax regimes are levied on.
- It is a gross figure: it says nothing about profitability, because marketing, bonuses, platform fees and duty all come out of it.
- GGR and net gaming revenue (NGR) are not interchangeable. Confusing the two overstates what an operator actually earns.
Formula
GGR = Total amount wagered − Total winnings paid to players
Sometimes called "gross win", "gaming win" or simply "revenue" in operator reporting. In sports betting the same figure is often expressed as turnover x hold percentage, because the sportsbook’s margin is what it retains from stakes.
Worked example
The figures below are round and illustrative, chosen to make the arithmetic legible.
An online casino takes 10,000,000 in stakes across a month and pays out 9,600,000 in winnings.
- GGR = 10,000,000 − 9,600,000 = 400,000
- As a share of turnover, that is a 4% hold
Note what GGR does not tell you. If the same operator awarded 120,000 in bonuses, paid 60,000 to affiliates and owed duty on the remainder, its net position is materially lower. GGR is the top of the funnel, not the bottom.
Why it matters
GGR is the most fundamental revenue metric in gambling. It represents the operator's gross profit before any deductions for bonuses, taxes, or operating costs. Most regulated markets use GGR as the basis for gaming duty calculation, license fees, and statutory reporting. Industry size comparisons across markets are almost universally on a GGR basis. The metric is robust, defined consistently across jurisdictions, and not susceptible to the methodology variations that affect NGR or active player counts.
GGR composition signals a lot about market and operator dynamics. Casino GGR is typically a higher percentage of underlying turnover than sportsbook (because casino margins are wider). Live casino GGR has grown faster than slot GGR in many markets over recent years. Sportsbook GGR is event-driven, with major football tournaments and US sports peaks visible in monthly data. Operator GGR by vertical, by market, and by channel (web, mobile, app, retail) is the standard breakdown in earnings disclosures.
GGR (Gross Gaming Revenue) vs Net gaming revenue (NGR)
| GGR (Gross Gaming Revenue) | Net gaming revenue (NGR) |
|---|---|
| Stakes minus player winnings. A gross figure, calculated the same way almost everywhere, which is why regulators use it as a tax base. | GGR minus agreed deductions - typically bonuses, and depending on the contract also gaming duty, payment processing and platform fees. Definitions vary between agreements. |
Revenue-share deals are almost always struck on NGR, not GGR. Two contracts quoting the same percentage can pay very differently depending on what each one deducts.
The bottom line
GGR measures what an operator retains from betting activity before any cost is taken out. It is the right number for sizing a market or a tax base, and the wrong number for judging whether an operator makes money.
Frequently asked questions
What's the difference between GGR and NGR?
GGR is gross gaming revenue (stakes minus winnings). NGR is net gaming revenue, deducting bonus costs, gaming duty contributions in some operator definitions, and other adjustments. NGR is closer to operator commercial revenue; GGR is the regulatory and industry-comparison metric. Most operators report both.
Why is GGR sometimes negative for a period?
When player winnings exceed stakes in a period, GGR for that period is negative. This happens occasionally in sportsbook on operators with small books that take heavy losses on a major event going against the operator's exposure. It also happens occasionally in early periods for a new operator or new product launch.
