The UK Gambling Commission’s latest statistics show a total Gross Gambling Yield (GGY) of £15.1 billion for the year to March 2023. This figure, effectively the UK’s term for GGR, is the foundation of financial reporting and analysis in the British gambling sector.
Understanding this metric is fundamental for any professional in this business. Put simply, Gross Gaming Revenue (GGR) is the amount wagered by players minus the winnings they are paid back. It is the core revenue an operator generates before deducting operational costs.
Calculating Gross Gaming Revenue
The formula for GGR is: Total Bets - Total Winnings = GGR. If a casino takes £500,000 in wagers and pays out £470,000 in prizes, the GGR is £30,000.
This figure is 'gross' because it excludes other expenses like marketing, affiliate commissions, and salaries. Player bonuses and promotional credits are also typically excluded from this calculation.
GGR vs. Net Gaming Revenue (NGR)
The distinction from Net Gaming Revenue (NGR) is vital. NGR refines the view of performance by subtracting direct costs from this revenue.
The calculation is generally: GGR - Bonuses - Chargebacks - Fees = NGR. For affiliates on revenue share deals, NGR is the figure that truly matters as it forms the basis of commission.
The Importance of GGR in the UK Market
Gross Gaming Revenue is a critical indicator for multiple stakeholders. For operators, it is the primary measure of top-line performance, showing the earning power of their games.
For regulators like the UK Gambling Commission, GGY is the basis for calculating fees and tax. HM Revenue & Customs (HMRC) levies Remote Gaming Duty (RGD) as a percentage of GGY from UK customers. A small but important point: use the official term GGY in formal correspondence with UK regulators.
If you are an affiliate, understanding how your operator partner calculates this figure is the first step to verifying your NGR-based earnings.
While GGR remains the industry’s headline metric, sophisticated operators are focusing more on Net Gaming Revenue and Customer Lifetime Value (CLV). These provide a clearer picture of sustainable profitability.
A high gross revenue means little if the costs required to generate it result in a net loss. The real health of an iGaming business is found further down the profit and loss statement.
