GGR Meaning in iGaming: Formula, Example and GGR vs NGR

GGR meaning: GGR stands for Gross Gaming Revenue, the iGaming metric that measures how much a betting operator or online casino won over a period: total wagered minus total paid out in winnings. If players wagered US$100,000 and the house paid US$85,000 in winnings, GGR is US$15,000 (illustrative numbers) — before any deduction for bonuses, operating costs or taxes.

What is GGR in iGaming?

In iGaming, GGR is the house’s take from player activity: what players lost to the operator, net of what they won back. Every losing bet adds to it; every payout subtracts from it. It’s the top line of an operator’s revenue — the number that bonuses, taxes, affiliate payouts and costs all come out of. It’s also the base many regulators use for gambling taxes, which is why operators report it. You’ll also see it called gross gambling revenue, and in the UK, Gross Gambling Yield (GGY).

How to calculate GGR

The formula is simple:

GGR = total wagered − total winnings paid

Illustrative example, just to show the math (not real data from any operator): in one month, players at a casino wager US$200,000 and receive US$170,000 in winnings. The month’s GGR is US$30,000. Divide GGR by total wagered and you get the share of the handle the house kept — 15% in this example, often called the hold or GGR margin.

That number tells you how much gross revenue the operation generated, but not yet how much was left over.

GGR is not profit

GGR is gross revenue, not net profit. It doesn’t deduct bonuses given to players, acquisition costs, taxes or operating expenses — only the difference between what came in as bets and what went out as winnings. It’s the starting point of the math, not the end result.

GGR vs NGR: what’s the difference

The term that usually shows up next to GGR is NGR (Net Gaming Revenue — see NGR meaning): GGR minus bonuses, promotions and, in some markets, industry-specific taxes. While GGR shows the gross volume the operation generates, NGR shows what’s actually left after the direct costs tied to gaming — the metric closest to “how much the house really made” before overhead.

Formula	Total wagered − winnings paid	GGR − bonuses, promotions and (in some markets) sector taxes or fees
What it shows	Gross volume the operation generates	What’s left after direct gaming costs
Illustrative example	US$15,000	US$12,000 (after US$3,000 in bonuses)
Where affiliates run into it	Rarely; it stays with the operator	Often, as the base for revshare deals

Why GGR matters if you run traffic

If you’re an affiliate or media buyer running campaigns for iGaming operators, you usually don’t see GGR directly — it stays on the operator’s side. What reaches you is typically the FTD (first-time deposit) of each lead, the event used to optimize campaigns in Meta Ads. Still, understanding GGR helps explain why some operators pay a higher CPA than others for the same kind of traffic: one vertical (casino) tends to have higher GGR per player than another (sports betting), which changes how much the house can pay per acquisition without losing margin.

GGR and traffic quality

An affiliate or media buyer who delivers leads that deposit and keep playing contributes to a higher GGR per player — and that’s the kind of lead operators tend to value (and pay better for) over time, more than someone who delivers only the FTD and nothing after. That’s why tracking only the Telegram channel join isn’t enough: without visibility of the FTD (and, when available, repeat deposits) via a server-to-server (S2S) postback, you can’t tell whether a creative is bringing players who stay or players who deposit once and disappear.

See the iGaming S2S postback guide to understand how the FTD reaches your tracking, and the real CPL ranges by vertical to compare acquisition costs between iGaming and other niches.

What is GGR in iGaming? It’s total wagered minus winnings paid: the operator’s gross revenue, before bonuses, costs and taxes.

What is NGR? It’s GGR after bonuses, promotions and sector taxes. Details in what NGR means.

Who calculates GGR? The operator. Affiliates and media buyers usually only see the FTD and, in revshare deals, the payout calculated on GGR or NGR — see revshare attribution in iGaming.
