CPA, CPL and Revenue Share Explained

Financial performance figures and charts on screen

Key takeaway

CPA pays a set amount when a defined action happens, usually a purchase. CPL pays for a lead that meets agreed criteria. Revenue share pays a percentage of what the customer spends, sometimes on renewals too. The best model depends on your audience, the offer and, above all, what gets reversed.

Commission models decide what kind of content pays. A model that rewards the first purchase favors comparison and buying-guide content. A model that rewards renewals favors audiences who stay with a product. Here's how each one works, with hypothetical numbers so you can compare them on equal terms.

CPA: payment for a defined action

Cost per action (CPA) pays a fixed amount when a customer completes a specific action. In health and beauty, that action is usually a first purchase, but it can also be a subscription start or a first paid month.

What to confirm:

The exact action. "Sale" can mean any order, or only first orders above a minimum value.
Exclusions. Free trials, heavily discounted orders, existing customers and orders using unauthorized coupons are often excluded.
Reversal window. How long a refund or chargeback can cancel your commission.

CPA is easy to forecast and suits content that helps people decide, such as reviews and comparisons.

CPL: qualified lead requirements

Cost per lead (CPL) pays when someone submits information and meets agreed qualification rules. It's common for services, including some telehealth programs, where the sale closes later.

What to confirm:

What qualifies. Required fields, eligible locations, age, duplicate rules and validation steps.
Who decides and when. Lead quality is often judged after the fact. Ask how long the advertiser has to reject leads, and why.
Consent. If leads are contacted by phone or text, consent rules apply. Never generate leads with incentives or misleading forms.

Revenue share pays a percentage of what the customer spends. The key question is: a percentage of what?

Basis	What it means
Gross sales	The order total, sometimes including shipping and tax
Net sales	Order value after discounts, refunds, tax and shipping
Recurring	A percentage of each renewal for a set period or for as long as the customer stays

Net is more common and fairer to advertisers, but it lowers the effective rate. A 30% share of net can pay less than a 20% share of gross.

Worked hypothetical comparisons

Hypothetical example

Assumptions (illustration only): 1,000 visitors, a 2% purchase rate (20 orders), a $60 average first order, 10% of orders refunded, and 40% of customers buying a second month.

CPA at $25 per first order: 20 orders × $25 = $500, minus 2 refunded orders ($50) = $450.
Revenue share at 30% of net: 20 × $60 × 30% = $360, minus refunds (2 × $18 = $36) = $324, plus 8 repeat orders × $60 × 30% = $144, so $468 if repeat orders are credited.
CPL at $5 per qualified lead: 1,000 visitors with a 6% lead rate gives 60 leads, and 80% qualifying gives 48 × $5 = $240.

Refunds, repeats and recurring terms

The details at the bottom of the terms often matter most.

Repeat purchases versus recurring commission. Some programs credit a customer's later orders only if they return through your link. Others tie the customer to you for life. Ask which applies.
Subscription cancellations. If a customer cancels in the first month, does your commission reverse?
Hold periods. Commissions often stay pending for 30 to 90 days to cover refunds. Factor that into your cash flow.
Caps and changes. Check whether payouts are capped and how much notice the program gives before changing rates.

When two programs look close, choose the one with clearer reversal rules. Predictable earnings are worth more than a slightly higher headline rate.

Frequently asked questions

Which commission model pays best?

None, in general. CPA rewards first purchases, revenue share rewards repeat customers, and CPL rewards lead volume that meets quality rules. Model your expected earnings with each program's actual terms.

What should I ask for before choosing a model?

The payable event in writing, the calculation basis (gross or net), exclusions, the reversal window, the hold period, and whether repeat or recurring orders are credited.

Can a program change its commission terms?

Usually, yes. Check the notice period in the terms, and keep a copy of the terms you joined under.
