The commission you pay an affiliate is only one component of your total cost to acquire a customer through the affiliate channel. Understanding the full cost structure is critical for setting rates that are sustainable at scale. Many operators discover too late that their "profitable" CPA rate becomes unprofitable when they add bonuses, processing fees, and operational overhead.
Total Cost of Affiliate Acquisition
Your true affiliate CAC (customer acquisition cost) includes every expense directly attributable to acquiring and activating a customer through the partner channel. This goes beyond the commission payment itself.

Commission payout

$400 CPA
$40 CPA
Welcome bonus / deposit match
$50 (100% match on $50)
$0 (no standard bonus)
$0 (no bonus)
Payment processing (deposit)

Affiliate manager time (prorated)
$5-$15
$10-$25
$3-$8
Total effective CAC
$261-$281
$418-$448
$47-$58
These numbers are illustrative ranges based on common program structures. Your actual costs depend on your payment methods, platform fees, bonus policy, and team size. The key point is that commission is typically 70-85% of total affiliate CAC, not 100%.
LTV-to-CAC Ratio: The Core Metric
The ratio of customer lifetime value to customer acquisition cost determines whether your affiliate program is profitable. A healthy LTV-to-CAC ratio for affiliate-acquired customers varies by vertical, but the general framework applies everywhere.
LTV:CAC below 1.0 -- your program loses money on every customer. Immediate rate reduction or qualification tightening needed
LTV:CAC of 1.0-2.0 -- breakeven to thin margin. Sustainable only if you have volume and operational efficiency
LTV:CAC of 2.0-3.0 -- healthy range. Room for rate increases to attract higher-quality affiliates
LTV:CAC above 3.0 -- strong economics. You may be underpricing and leaving affiliate acquisition opportunity on the table
In iGaming, a casino operator with an average player LTV of $600 and total affiliate CAC of $270 has an LTV:CAC of 2.2 -- a healthy ratio. If the same operator offers $300 CPA to attract premium affiliates, the total CAC rises to approximately $370, and the ratio drops to 1.6. Still profitable, but with less margin to absorb player quality variation.
RevShare Economics Are Different
RevShare models do not have a fixed CAC because the commission is an ongoing percentage of revenue. This changes the economic calculation from a one-time acquisition cost to a margin-sharing model. The operator question shifts from "can I afford this CPA?" to "what percentage of each customer's revenue can I share while maintaining operational margin?"
A 30% RevShare on NGR means the operator retains 70% of net gaming revenue from affiliate-referred players. After deducting game provider fees (typically 10-15% of GGR), payment processing (2-5%), and operational costs, the effective operator margin on affiliate-referred players under RevShare is typically 30-45%. Compare this to CPA models where the operator retains 100% of revenue after the upfront acquisition cost is recovered.
Calculating Your Rate Ceiling
Your rate ceiling is the maximum commission you can pay while maintaining your target margin. Calculating this number prevents emotional or competitive rate-setting that erodes profitability.
Step 1: Calculate average customer LTV for affiliate-acquired customers (not overall LTV -- affiliate traffic often converts differently)
Step 2: Subtract all non-commission costs (bonuses, processing, platform, overhead)
Step 4: The remaining amount is your maximum commission budget per customer
Step 5: Test this ceiling against market benchmarks -- if it is below market, you need to improve conversion or LTV before competing on rate
Never set your commission rate at or near your ceiling. Leave a 15-20% buffer for rate negotiations with high-value affiliates, seasonal promotions, and LTV fluctuations. Your published rate should be 70-80% of your ceiling.
Key Takeaways
Commission is typically 70-85% of total affiliate CAC -- always calculate the full cost including bonuses, processing, and overhead
Target an LTV:CAC ratio of 2.0-3.0 for sustainable affiliate program economics
RevShare economics are margin-sharing, not fixed-cost -- model them differently from CPA
Calculate your rate ceiling before setting or adjusting rates to prevent margin erosion
Keep your published rate at 70-80% of ceiling to preserve negotiation room
