Affiliate terms nobody tells creators
Why a 40% Affiliate Commission Can Pay Less Than 20%
A bigger percentage can look like a better deal. But the percentage only helps once you know what it applies to, how long it lasts, and whether your referral qualifies.
When you compare affiliate programs, “40% commission” and “20% recurring” are incomplete descriptions. One might pay on the first invoice. The other might pay on several eligible invoices. A useful comparison starts with the customer and the terms, then does the math.
All amounts below are hypothetical teaching examples, not actual program offers, measured results or an earnings forecast.
The same customer, two different outcomes
Suppose both programs sell a $50 monthly subscription. Assume the same referred customer makes six eligible monthly payments, every commission is approved, and there are no discounts, refunds, fees or exclusions.
| Term | Program A | Program B |
|---|---|---|
| Headline rate | 40% | 20% |
| Eligible payments | First payment only | Six monthly payments |
| Calculation | $50 × 40% | $50 × 20% × 6 |
| Illustrated commission | $20 | $60 |
The lower rate produces more commission in this example because it applies to more payments. If the customer cancels after one month, Program B produces $10 instead. Recurring commissions depend on eligible payments continuing; the label alone does not establish a better offer.
Eligible revenue × commission rate × eligible payments
This simplified calculation compares a percentage-based offer for one customer. It is not a full earnings model. Fixed bounties, tiered rates, different conversion rates, refund rates, customer retention and acquisition costs require their own assumptions.
1. Ask what the percentage applies to
Does the commission cover the full invoice, only an eligible plan, or revenue after exclusions? Does an annual purchase qualify differently? Do existing customers count? Read the offer and agreement rather than applying the headline rate to every purchase.
For a real example of why the qualifying event matters, Shopify’s official affiliate earnings guidance describes commissions for full-price plan referrals. A click or trial signup alone should not be treated as an approved payout. Read Shopify’s earnings guidance.
2. Separate the cookie window from commission duration
The referral tracking window concerns attribution: whether a later action can be credited to your referral. Commission duration concerns which eligible payments can generate commission after the referral qualifies. A 90-day tracking window does not, by itself, mean 90 days of recurring payments.
A longer window can help when customers take longer to decide, but it cannot guarantee credit. PartnerStack documents several reasons referrals may not track, including another partner’s link, expired or cleared cookies, and a different browser or device. The exact attribution rules depend on the program. Read PartnerStack’s tracking explanation.
3. Read what “recurring” actually promises
Look for a time limit, the eligible plan, continued customer payments and any conditions on the partnership. “Recurring” could describe several payments without promising an unlimited stream. “Lifetime” also needs a definition in the agreement; do not substitute your own interpretation.
If the public page leaves the duration unclear, write “not stated” in your comparison and ask the program before relying on it. Do not convert missing information into “unlimited.”
4. Distinguish recorded, approved and paid
A dashboard entry is not necessarily money ready to withdraw. Check the review process, refund rules, payment schedule, minimum payout and required account setup. PartnerStack explains that a company may remove a customer, transaction or commission following a refund, cancellation or an event that did not qualify under its offer. Read PartnerStack’s company and commission guidance.
5. Choose for your audience and promotion method
A favorable payout structure does little for a product your audience does not need. Start with a problem you can help people solve. Then check that the program allows your intended channel and content. Paid search, coupon sites, email, social posts and brand bidding may have different restrictions.
Compare offers only after understanding those differences. Avoid presenting the mathematical winner in a simplified example as the best program for every creator.

Put the comparison to work
Search your content topic on AffiFind, shortlist relevant programs, and inspect their recorded terms. Follow the official source to confirm the current offer before applying. A catalog entry is a research starting point; a missing value is not proof that no restriction exists.
