What is GGR? A Simple Guide to Gross Gaming Revenue

If you’ve ever peeked into the world of casinos, online gambling, or sports betting, you’ve probably come across the acronym GGR. But what is GGR, and why is it such a big deal in the gaming industry?

Let’s break it down in a simple, no-jargon way—plus share some real-world insights to help you understand why this figure matters for regulators, operators, and even you as a player.

🎯 What Does GGR Stand For?

GGR stands for Gross Gaming Revenue.

It represents the total amount wagered by players minus the winnings paid out to them. In simple terms, it’s the “net revenue” a gaming operator earns before any costs like taxes or operational expenses are deducted.

Formula:

GGR = Total Amount Bet – Total Winnings Paid

Example:

Let’s say in one day, a casino’s slot machines receive $1 million in bets. If they pay out $950,000 in winnings, the GGR for the day is:

$1,000,000 – $950,000 = $50,000 GGR

🎲 Why Is GGR Important?

GGR is the key financial metric used by:

Regulators and governments to determine taxes and licensing fees
Gaming operators to assess performance and profitability
Investors to gauge the health of gaming businesses

Unlike total turnover (which only shows how much was bet), GGR gives a clearer picture of actual earnings.

📊 GGR vs. NGR vs. Turnover

Another commonly used term in gaming is NGR (Net Gaming Revenue). While GGR is the gross figure, NGR factors in bonuses, comps, and promotional costs.

NGR = GGR – Bonuses – Player Incentives

And then there’s Turnover, which refers to the total amount wagered.

Metric	Formula	Purpose
GGR	Bets – Winnings	Gross income pre-expenses
NGR	GGR – Bonuses/Incentives	Actual income after incentives
Turnover	Total amount wagered	Shows betting volume
