I have been paid both ways. Fixed CPA — a flat dollar amount per sale, no matter what. And RevShare — a percentage of whatever the customer spends. Both have made me money. Both have also cost me money in ways I didn't expect early on.
When Rachel and I set up the affiliate program for Pagewheel, we chose % recurring RevShare. That decision wasn't random. It was based on twenty years of being on the other side and knowing exactly what makes affiliates promote harder — and what makes them walk away.
Here's what you actually need to know to pick the right model. Whether you're promoting or selling.
What CPA Means in Practice
CPA stands for Cost Per Action. In affiliate marketing, it almost always means a flat dollar amount per sale. The vendor says: "I'll pay you $50 every time someone you refer buys." Done. Simple.
You don't care what the customer's cart total is. You don't care if they return the product. You don't care if they buy three upsells. Your $50 is your $50.
Why affiliates love CPA:
- You know your profit margin before you spend a dollar on ads. If your CPA payout is $50 and your cost per acquisition is $35, you're profitable. Period.
- Refunds and chargebacks are the vendor's problem. Your commission is locked.
- Scaling math is dead simple. More traffic at the same cost = more profit. No variables.
Why vendors offer CPA:
- It attracts paid media affiliates — the ones with ad budgets who can scale fast. These affiliates will not touch an offer unless they can calculate exact margins before spending.
- It's predictable. You know exactly what each sale costs you in affiliate payouts.
- The tradeoff: if your average order value fluctuates or your upsell flow is strong, you might be paying the same CPA on a $50 sale and a $300 sale. That margin management falls on you.
What RevShare Means in Practice
RevShare means the affiliate earns a percentage of the sale. If the commission is 75% and the product sells for $100, the affiliate makes $75.
Simple math — but the variables underneath are more complex than CPA.
Why affiliates love RevShare:
- The upside is higher. If you're sending quality traffic that converts well and doesn't refund, you'll almost always earn more on RevShare than CPA over time.
- Recurring offers are where RevShare shines. A subscription product paying 30% recurring means one referral keeps paying you every month the customer stays. That compounds.
- Higher cart values benefit you directly. If the customer buys the upsell, your commission goes up. With CPA, it doesn't. There are specific ways to increase your average order value that directly boost RevShare earnings.
Why vendors offer RevShare:
- Risk is shared. If a customer refunds, the affiliate's commission adjusts too. This protects the vendor's margins.
- It attracts affiliates who focus on quality over volume — because their earnings are tied to customer behavior, not just the initial click.
- It's easier to stay profitable. As long as your product costs less to deliver than what you keep after the commission split, you're in the green.
Vendors can reduce chargebacks and refunds on their end, which directly protects their affiliates' RevShare earnings too.
The Decision Framework
This is not a "which is better" question. It's a "which fits your situation" question.
What I Learned Setting Commission Rates as a Vendor
When we launched Pagewheel's affiliate program, I already knew what I wanted as an affiliate. Recurring revenue. A product that retains customers. A commission that rewards me for sending quality traffic that sticks around.
So we set 30% recurring RevShare. Every month a referred customer stays on Pagewheel, their affiliate gets paid again. Some months, our top affiliates earn more per customer than we do. And that's fine — because those affiliates are bringing us customers we'd never reach on our own, and the lifetime value of a retained subscriber makes the math work for everyone.
If we'd offered a flat CPA instead, we might have attracted more paid media affiliates upfront. But we'd have lost the content creators and community builders who promote Pagewheel because they genuinely use it and want recurring income — not a one-time payout.
That's the real strategic decision for vendors. CPA attracts volume and speed. RevShare attracts loyalty and quality. Most successful programs on Digistore offer both — a CPA option for media buyers and a RevShare option for organic affiliates — because different affiliate types need different incentive structures.
If you’re still deciding what to pay, here’s a deeper look at affiliate commission rates.
The Math That Matters
Forget which model sounds better in theory. Run the numbers for your specific situation.
If you're an affiliate, calculate:
- What's my cost to generate one sale? (Ad spend, or time investment for organic)
- What's the average payout per sale under each model?
- What's the refund rate on this offer? (RevShare penalizes you for refunds. CPA doesn't.)
- Is there recurring billing? (If yes, RevShare almost always wins long-term.)
If you're a vendor, calculate:
- What's my average order value including upsells?
- What CPA amount keeps me profitable at that AOV?
- What's my customer refund rate? (High refunds = CPA costs you more because you eat them alone.)
- What type of affiliate do I want to attract? (Media buyers = CPA. Content creators = RevShare.)
On Digistore, both models are available on the same platform. Typical commission rates range from 50% to 85% on RevShare offers. CPA amounts vary by product and niche. You can see conversion rates, average order values, and refund rates in the marketplace before you ever promote — which means you can run these calculations before committing to anything.
Pick Based on Math, Not Preference
CPA is not better than RevShare. RevShare is not better than CPA. The right model depends on your traffic type, your risk tolerance, and whether the offer has recurring billing.
If you're running paid ads: start with CPA offers until you have enough data to know your traffic's refund rate. Then test RevShare offers where the math favors you.
If you're building organic traffic: RevShare with recurring commissions is how you build an income stream that compounds. One referral paying you $14/month for two years is worth more than a one-time $50 CPA — and you didn't spend anything on ads to get it.
Run the numbers. Pick the model. Promote accordingly.
