ARPU (Average Revenue Per User) is a metric that shows how much revenue an average active user generates over a specific period. It is used to evaluate audience monetization, compare GEOs and traffic sources, and track offer performance over time.

In gambling and betting, ARPU helps affiliates assess the value of acquired users for a product. However, it is important to understand which revenue figure is used in the calculation and how the operator defines an active user.

For affiliates, ARPU is particularly useful as a periodic metric. It makes it possible to compare traffic quality and audience monetization without immediately evaluating the entire user lifecycle.

What Is ARPU and How Is It Calculated?

ARPU stands for Average Revenue Per User. In simple terms, it shows the average amount of revenue generated by one active user during a selected period.

The basic formula is:

ARPU = revenue for the period / number of unique active users during the same period

For example, if a platform generates €50,000 in attributable revenue during a month and has 1,000 unique active users, the ARPU is:

€50,000 / 1,000 = €50

This means that one active user generated an average of €50 in revenue during the month.

Before calculating ARPU, two parameters should be clearly defined:

  • which revenue metric is used in the numerator;
  • who qualifies as an active user.

Depending on the reporting methodology, the revenue figure may be based on GGR, NGR, or another revenue metric. Therefore, ARPU comparisons between offers are meaningful only when the calculation methodology is comparable.

For example, GGR in online gambling and casino can be used as the revenue base for calculating user-level revenue. However, ARPU should not automatically be treated as the same thing as GGR per player.

ARPU vs. ARPPU vs. LTV: What Is the Difference?

ARPU, ARPPU, and LTV are all used to evaluate audience value, but they measure it from different perspectives.

ARPU

ARPU measures the average revenue generated by an active user during a selected period. The denominator includes all users who meet the platform's definition of activity, including users who have not made a payment.

ARPPU

ARPPU (Average Revenue Per Paying User) measures the average revenue generated by a paying user during a specific period.

The formula is:

ARPPU = revenue from paying users / number of unique paying users

A paying user is someone who has made at least one qualifying payment according to the platform's methodology.

With the same period and the same revenue metric, ARPPU is usually higher than ARPU because its denominator includes only a subset of users — those who have made a payment.

However, these metrics should only be compared directly when the revenue definition and calculation period are consistent.

LTV

LTV (Lifetime Value) measures the value generated by a user throughout the entire period of their relationship with a product.

Unlike ARPU, LTV is not limited to a single week or month. It is used to estimate the actual or projected value of a user over their lifecycle.

How to calculate LTV and estimate user lifetime value can include ARPU as one of the input metrics.

In a simplified model, periodic ARPU can be multiplied by the expected number of active periods. However, this is only an approximation. LTV is also affected by retention, churn, changes in user behavior, and other factors.

How to Use ARPU in Traffic Arbitrage

For affiliates, ARPU is particularly useful when comparing different traffic funnels, GEOs, or traffic sources.

Using ARPU to Compare GEOs

The same number of acquired users does not guarantee the same audience value across different GEOs.

ARPU can be affected by purchasing power, gaming session frequency, average deposit size, local market characteristics, and available payment methods.

Therefore, when analyzing GEO and traffic geography, affiliates should look beyond registrations and FTDs and also evaluate how the acquired audience is subsequently monetized.

Using ARPU to Evaluate Traffic Sources

ARPU can be used to compare different traffic sources in affiliate marketing.

For example, one source may generate a large number of registrations but a low average revenue per active user. Another may generate fewer registrations while delivering a more valuable audience.

However, ARPU should not be analyzed independently of acquisition costs. To evaluate the economics of a traffic funnel, it is useful to compare ARPU with CAC, advertising expenses, and the terms of the affiliate program.

Using ARPU to Track Offer Performance

ARPU can be calculated weekly, monthly, or over another defined period. This makes it possible to monitor changes in audience monetization.

Short periods are useful for operational analysis but can be more volatile. This is particularly relevant in sports betting during major sporting events, when user activity and betting volumes can change significantly.

For longer-term conclusions, it is better to compare equivalent periods and account for seasonality.

What Affects ARPU in Gambling and Betting?

Several factors can influence ARPU.

User activity. The frequency of gaming sessions and bets affects the volume of transactions and potential product revenue. In betting, the frequency and size of bets are particularly relevant.

Average deposit size and payment activity. More active users who deposit and transact more frequently can generate greater potential monetization.

Bonus policy. Welcome bonuses, no-deposit bonuses in online gambling, free spins, and other promotional mechanics can influence user behavior and overall revenue. Therefore, ARPU comparisons should ideally use equivalent periods and promotional conditions.

Traffic quality. Users acquired from different sources may vary significantly in engagement, payment behavior, retention, and long-term value.

GEO. Audience economics, payment infrastructure, regulation, and user behavior vary between markets.

Payment infrastructure. Access to familiar payment systems in iGaming can influence deposit conversion and subsequent user activity.

Retention. Users who continue returning to a product have more opportunities to generate revenue in subsequent periods. Therefore, user retention and audience retention in iGaming should be considered when interpreting ARPU.

How Are ARPU, ARPPU, FTD, NGR, and Other Metrics Related?

These metrics do not form a sequential funnel. Instead, they describe different aspects of product economics and affiliate traffic performance.

FTD and first-time deposits in affiliate marketing indicate the number of users who made their first deposit and are commonly used to evaluate acquisition and conversion performance.

ARPU measures average revenue per active user over a specific period.

ARPPU measures average revenue per paying user over the same or another selected period.

NGR can be used as the revenue base for ARPU when the operator's methodology defines NGR as the relevant revenue metric.

RevShare determines the partner's share of the agreed revenue base. Therefore, a higher ARPU can potentially translate into higher affiliate earnings under suitable RevShare terms. However, the relationship depends on the specific affiliate program and its calculation methodology.

LTV measures user value over the entire lifecycle. ARPU can serve as one of the inputs for forecasting it.

Hold in sports betting and online gambling should also be considered separately. With the same betting turnover, a higher hold can indicate higher gaming revenue for the operator. This can potentially increase revenue-based ARPU, provided that other factors remain constant and the relevant revenue methodology supports this interpretation.

Chargebacks can also affect ARPU if the amount of chargebacks is deducted from the revenue figure used in the numerator.

Why Is ARPU Important for Affiliates?

ARPU allows affiliates to evaluate traffic not only through registrations or first-time deposits but also through the subsequent value generated by the audience.

For example, two traffic funnels may generate the same number of FTDs. However, users from one funnel may return more frequently, place more bets, or remain active for longer. As a result, their ARPU may be higher.

Therefore, when evaluating an offer, it makes sense to monitor several metrics simultaneously:

  • registrations;
  • FTD;
  • ARPU;
  • ARPPU;
  • retention;
  • LTV;
  • affiliate revenue under the program's terms;
  • advertising expenses;
  • final profit.

This approach provides a more complete picture of traffic quality and offer economics.

Common ARPU Calculation Mistakes

Confusing ARPU with ARPPU. ARPU is calculated for active users according to the defined methodology, while ARPPU is calculated only for paying users.

Comparing metrics based on different methodologies. If one offer calculates ARPU using GGR and another uses NGR, a direct comparison may be misleading.

Ignoring the calculation period. Weekly and monthly ARPU are different metrics and should not be compared automatically without considering the period, methodology, and audience structure.

Using ARPU as a substitute for LTV. ARPU measures revenue generated during a specific period, while LTV estimates user value over the entire lifecycle.

Ignoring audience composition. Changes in the number and structure of active users can significantly affect ARPU even when total revenue remains stable.

Looking at ARPU in isolation. A high ARPU does not guarantee high affiliate profit. Acquisition costs, RevShare or CPA terms, retention, and other economic factors also need to be considered.

How to Calculate and Analyze ARPU Correctly

For practical analysis, affiliates should follow several basic rules:

  1. Define the calculation period.
  2. Establish which users qualify as active.
  3. Define the revenue metric used in the numerator.
  4. Use the same methodology when comparing different offers.
  5. Analyze changes across comparable periods.
  6. Compare ARPU with ARPPU, FTD, retention, and LTV.
  7. Include advertising costs and affiliate program terms when evaluating profitability.

ARPU is most useful as part of a broader performance analysis. It shows how much revenue an average active user generates, but it does not capture the complete economics of a user or affiliate traffic funnel.

ARPU in Gambling and Betting: How to Analyze Traffic Value

ARPU (Average Revenue Per User) measures the average revenue generated by an active user during a specific period. In gambling and betting, it helps analyze audience monetization, compare GEOs and traffic sources, and track changes in the quality of acquired users.

The key point is not to treat ARPU as a standalone profitability metric. A meaningful analysis requires a clear understanding of the revenue methodology, the composition of the active audience, and the calculation period.

Combined with FTD, ARPPU, retention, LTV, and other performance metrics, ARPU gives affiliates a more accurate view of traffic value and the potential economics of an offer.

FAQ

What is ARPU in simple terms?

ARPU (Average Revenue Per User) shows how much revenue an average active user generates during a selected period. The basic formula is revenue for the period divided by the number of unique active users during the same period.

What is the difference between ARPU and ARPPU?

ARPU is calculated for active users according to the defined methodology, while ARPPU is calculated only for paying users. Therefore, with the same period and revenue metric, ARPPU is usually higher than ARPU.

Can LTV be calculated using ARPU?

ARPU can be used as one of the inputs for forecasting LTV. In a simplified model, periodic ARPU is multiplied by the expected number of active periods. However, this is an approximate calculation because LTV is also affected by retention, churn, and changes in user behavior.

What is the best period for calculating ARPU?

ARPU can be calculated weekly, monthly, or over another period that fits the purpose of the analysis. Short periods are useful for operational monitoring, while longer-term analysis should use comparable periods and account for seasonality. In sports betting, major sporting events can have a significant impact on the results.

Why can ARPU increase while profit decreases?

ARPU measures average revenue per active user and does not account for all business expenses. It can increase when revenue grows faster than the number of active users, while acquisition costs or other expenses may grow even faster. Therefore, ARPU should not be treated as a direct substitute for profit.
