What Is CPA and How Is It Calculated

CPA stands for Cost Per Acquisition — a fixed payout paid by the affiliate program each time a referred player completes a qualifying First-Time Deposit (FTD). Once the qualifying conditions are met, the affiliate receives a one-time commission regardless of the player's future activity.

The CPA calculation process works as follows:

1. The affiliate sends traffic to the platform.
2. A visitor registers an account.
3. The player completes a qualifying FTD.
4. The affiliate receives the agreed CPA payout.

The formula is straightforward:

CPA income = Number of qualifying FTDs × CPA rate

Worked example:

10 qualifying FTDs × €200 CPA = €2,000 total CPA income

The definition of “qualifying” varies by affiliate program. Most programs require a minimum first deposit of €10–€20, and some also require a minimum level of wagering activity before the FTD is approved. If a player deposits below the threshold or fails verification checks, the affiliate receives €0 for that referral.

According to irev.com's 2026 affiliate payout research, average CPA ranges in the iGaming industry vary by market tier:

1. Tier-1 markets: €130–€400 per FTD
2. Tier-2 markets: €45–€120 per FTD
3. Tier-3 markets: €10–€60 per FTD

Affiverse Media's 2026 benchmark data also show that premium affiliate programs offer higher CPAs, with some reaching €650–€700 for high-performing traffic sources.

Big Betty Partners structures CPA rates by traffic source:

1. PPC traffic: €300–€700
2. FB/ASO traffic: €100–€250
3. SEO traffic: €100–€600
4. Influence traffic: individual terms

Reg-to-deposit conversion rates also vary significantly by traffic source:

1. SEO/PPC traffic: 20–60% reg2dep
2. FB/ASO traffic: 30–50% reg2dep
3. In-app traffic: 15–30% reg2dep

Using SEO traffic as an example:

1. 100 visitors
2. 10–20 registrations
3. 2–12 depositing players

Affiliates themselves remain responsible for traffic quality and traffic-source compliance.

What Is RevShare and How Is It Calculated

RevShare means the affiliate receives a percentage of the platform's Net Gaming Revenue generated by referred players for as long as those players remain active. Unlike CPA, RevShare generates recurring income directly tied to long-term player activity.

The RevShare calculation process works as follows:

1. Players register through the affiliate referral link.
2. Players continue to deposit and use the platform over time.
3. The platform calculates monthly Net Gaming Revenue.
4. The agreed RevShare percentage is applied to the final NGR amount.

The core formula is:

RevShare income = NGR × RevShare rate

According to irev.com's 2026 payout analysis:

NGR = Gross Gaming Revenue – Bonuses – Chargebacks – Payment Processing Fees

In some markets, additional operational deductions may also apply before affiliate commissions are calculated.

Worked example based on irev.com benchmark data:

Revenue Stage	Amount
Gross Gaming Revenue (GGR)	€10,000
Bonuses deducted	−€1,500
Chargebacks deducted	−€300
Payment processing fees deducted	−€200
Final Net Gaming Revenue (NGR)	€8,000
35% RevShare payout	€2,800

Without deductions, a 35% RevShare on €10,000 GGR would equal €3,500. After deductions, the actual payout becomes €2,800.

The difference between GGR and NGR is typically 15–25%, meaning €10,000 in gross revenue generally produces €7,500–€8,500 in commissionable NGR.

To clarify the terminology:

1. GGR = bets minus player winnings
2. NGR = GGR minus operational deductions

Big Betty Partners currently structures RevShare payouts using the following performance tiers:

1. 0–5 FTDs → 25%
2. 6–10 FTDs → 30%
3. 11–20 FTDs → 35%
4. 21–40 FTDs → 40%
5. 41+ FTDs → 45%

Affiverse Media's 2026 benchmark data shows that leading affiliate programs in the iGaming industry commonly operate within the 25–55% RevShare range.

CPA vs RevShare: Same Traffic, Different Payouts

Using the same traffic scenario makes it easier to measure the difference between CPA and RevShare in practical terms.

Scenario:

1. 100 SEO visitors
2. 15 registrations (15% conversion rate)
3. 6 FTDs (40% reg2dep rate)
4. Average player NGR value: €200 per month
5. Average player lifetime: 3 months

CPA calculation:

6 FTDs × €200 CPA = €1,200 total payout

RevShare calculation:

6 players × €200 monthly NGR × 35% RevShare = €420 monthly payout

Side-by-side comparison:

Timeline	CPA Earnings	RevShare Earnings
Month 1	€1,200	€420
Month 3 cumulative	€1,200	€1,260
Month 6 cumulative	€1,200	€2,520

In this example, RevShare overtakes CPA by month 3. From month 4 onward, the affiliate continues to generate approximately €420 per month from the same players without acquiring additional traffic.

The breakeven point occurs when cumulative RevShare earnings exceed the original fixed CPA amount.

The structural difference between the models is straightforward:

1. CPA income stops when new traffic stops.
2. RevShare continues while referred players remain active.

Player retention significantly affects the outcome. If players stop depositing after month 1:

1. CPA total earnings: €1,200
2. RevShare total earnings after month 1: €420

Revenuelab.biz summarized the difference in its 2026 analysis: 2-week tests favor CPA; 6-month builds favor RevShare.

“Affiliates should monitor player retention before switching commission models. If players continue depositing consistently in months two and three, RevShare generally becomes more effective over the long term. Repeat deposits, second-month activity, and retention stability are the key indicators to watch before moving away from CPA.”

What Is Negative Carryover and Why Does It Matter for Your Income

Negative carryover occurs when player winnings generate a negative monthly NGR balance. Programs that apply negative carryover transfer this deficit into future months, reducing or eliminating upcoming RevShare payouts until the balance is cleared.

Negative carryover means that negative monthly balances continue to roll forward and are deducted from future affiliate commissions.

Worked example based on irev.com's 2026 payout analysis:

Month 1:

• Players lose €5,000
• NGR = €5,000
• 35% RevShare = €1,750 paid

Month 2:

• One player wins €12,000
• NGR becomes −€7,000
• Affiliate account deficit becomes −€2,450

Month 3:

• Players lose €6,000
• 35% RevShare equals €2,100
• The entire amount first clears the deficit
• Affiliate receives €0 payout

Without negative carryover:

1. A negative NGR in Month 2 is simply treated as €0.
2. No deficit carries into future months.
3. Month 3 starts from a clean balance.

Big Betty Partners operates with no negative carryover, meaning negative balances do not transfer into future commission periods.

Affiliates should always review the affiliate agreement and Terms & Conditions before joining a program. If negative carryover is not clearly addressed, it should be confirmed directly with the affiliate manager.

Programs applying negative carryover are more common among smaller affiliate programs, while larger programs increasingly use no-negative-carryover structures as a competitive advantage.

The Hybrid Model: CPA Plus Ongoing RevShare

Hybrid combines a fixed CPA payment with ongoing RevShare from the same referred players. The model is designed to provide immediate cash flow while also creating recurring monthly revenue.

Example structure:

€100 CPA per FTD + 20% RevShare on player lifetime activity

Worked example using the same 6-player traffic scenario:

6 FTDs × €100 CPA = €600 upfront

Ongoing RevShare component:

6 players × €200 monthly NGR × 20% RevShare = €240 monthly recurring income

Big Betty Partners offers Hybrid structures, as well as standalone CPA and RevShare agreements.

Hybrid agreements are typically offered to affiliates who demonstrate stable traffic quality and consistent volume. Beginners may need to negotiate Hybrid terms or first reach a minimum FTD threshold.

Hybrid models generally make sense when:

• Immediate cash flow is required
• Traffic demonstrates stable long-term retention
• Affiliates want recurring income without sacrificing upfront payouts
• Traffic-source performance data is already established

The trade-off is straightforward:

1. Hybrid CPA rates are lower than standalone CPA rates.
2. Hybrid RevShare percentages are lower than standalone RevShare percentages.
3. The model balances short-term and long-term earning potential.

For affiliates with stable traffic and strong player retention, Hybrid can provide a balanced approach that combines immediate payouts with scalable long-term revenue growth.
