Affiliate commission or discount code — which one are you actually reaching for?
They look similar and cost you similarly. They do completely different jobs, and using the wrong one is a quiet way to lose money.
A creator asks a podcaster to mention their course. The podcaster asks for something to offer listeners. The creator makes a code: POD20, twenty per cent off. It works, sort of, and it costs about the same as a commission would have. But the two tools behave very differently once you look at who pays and who gets paid.
Who the money comes from
With a discount code, the buyer keeps the money. Your revenue per sale drops, the promoter gets nothing, and the code leaks — into deal forums, group chats and browser extensions — where it goes on discounting sales that never needed discounting.
With a commission, the buyer pays your normal price and the promoter is paid out of the sale. Your revenue per sale drops by a similar amount, but the money goes to the person who caused the sale, which is the person you actually wanted to reward.
| Discount code | Affiliate commission | |
|---|---|---|
| Who benefits | The buyer | The promoter |
| Buyer pays | Less | Full price |
| Leaks? | Yes, codes travel | No, it's per-link |
| Rewards repeat effort | No | Yes, every sale |
| Creates urgency | Yes, with an expiry | Not by itself |
When each one is right
Reach for a discount when the job is urgency: a launch window, a seasonal push, a cart that needs a reason to close today. The expiry is the mechanism; the discount is just what makes the expiry matter.
Reach for a commission when the job is distribution: someone with an audience mentioning you repeatedly over months. A code rewards them once, awkwardly, and only if they negotiate. A commission rewards them every time, automatically, without either of you thinking about it.
The maths people get wrong
A 20% discount and a 20% commission cost you roughly the same per sale — but the discount also applies to the buyers who found you organically that week, and the commission doesn't. On a launch where half your sales come from your own list, the code is meaningfully more expensive.
Yes. The commission is then calculated on the discounted price, so the affiliate earns a percentage of what you actually collected rather than of the list price.
Usually more, because a code discounts every sale it touches, including the ones that were already yours. A commission only ever applies to a referred sale.
A code converts a hesitating buyer today. A commission gets you mentioned in the first place. They're not competing for the same job.
Use both: a code for the audience, a commission for whoever brought them.
