Key takeaways
- Four core models: percentage of sale, flat per-action, recurring, and tiered/performance-based.
- Percentage fits variable-priced products; flat per-action suits leads and signups.
- Recurring commission ties affiliates to retention — a strong fit for subscriptions.
- Tiers reward your best partners and push volume without overpaying everyone.
- Let your business model and margin pick the structure — not a competitor's headline rate.
How you structure commission decides which partners you attract, what behaviour you reward, and whether the program makes money. Get it right and affiliates chase the exact outcomes you care about. Get it wrong and you overpay for low-value actions — or never attract serious promoters at all. Here are the models that work, and when to use each.
What are the main affiliate commission models?
Four core models: percentage of sale, flat per-action, recurring, and tiered. Most programs pick one as the base, then layer tiers or bonuses on top to reward the best performers.
Percentage of sale
Pay a percentage of each order's value. It's the most common model and shines when order values vary, because the payout scales with the revenue. It also nudges affiliates to drive higher-value purchases.
Flat per-action (CPA / CPL)
Pay a fixed amount for a defined action — a qualified lead, a signup, or a sale. Flat rates are predictable and fit uniform pricing, or cases where you value an action (like a trial start) more than immediate revenue. The risk is paying for junk, so define "qualified" tightly.
Recurring commission
Pay a commission on every renewal, either indefinitely or for a capped period (e.g. 12 months). Recurring is the standout model for SaaS because it ties affiliates to retention: they earn more when the customers they referred stick around, so they're motivated to send good-fit users.
Tiered and performance-based
Raise the rate as a partner drives more volume — say 15% up to 10 sales a month, then 20% beyond that. Tiers reward your most productive partners and give everyone a reason to push, without paying a premium to partners who convert only now and then.
How does your business model decide the structure?
Your business model should pick the structure for you, because the right model mirrors how you actually make money. A subscription business earns over time, so it rewards retention with recurring commission. A one-off-purchase business earns at the point of sale, so a percentage or flat rate fits better.
- Subscription / SaaS: recurring commission (often capped at 6–12 months) ties affiliates to retention.
- One-off digital products: a percentage of sale scales the payout with order value.
- Lead generation: a flat per-lead rate, with a tight definition of a qualified lead so you don't pay for junk.
- Fixed-price products with uniform margins: a flat per-sale amount keeps every payout simple and predictable.
Don't confuse multi-tier with tiered
Tiered commission means one partner's rate rises with their own performance. Multi-tier (sub-affiliate) means a partner also earns a smaller cut when affiliates they recruited make sales. They solve different problems — performance vs. network growth — and Afflio supports both.
How do you combine models without overpaying?
Pick one base model that matches your pricing, then add targeted incentives — don't just raise the base rate for everyone. The cleanest structures keep a sustainable base and reserve the extra reward for behaviour you want more of.
- Pick a base: percentage for variable pricing, flat for uniform pricing, recurring for subscriptions.
- Add a volume tier so high performers earn a higher rate on their extra sales.
- Layer time-boxed bonuses for launches or specific products instead of permanently inflating the base.
- Cap or step down recurring commission after a set period to protect long-term margin.
Your commission structure is a strategy document in disguise. Whatever you pay the most for is what your affiliates will optimize their entire effort around.
What is the most common affiliate commission model?+
Percentage of sale is the most common, because it scales the payout with order value and suits variable pricing. Flat per-action and recurring models are widely used too, depending on whether you value uniform actions or subscription retention.
Is recurring commission worth it for SaaS?+
Usually yes. Recurring commission ties affiliates to retention — they keep earning as the customers they referred renew — which pushes them to send well-fit users rather than chase one-off signups. Many programs cap it at a fixed number of months to protect margin.
Should every affiliate get the same commission rate?+
Not necessarily. A flat base rate is simplest, but tiered or performance-based rates let you reward your highest-volume partners more without overpaying the occasional ones. Many programs pair a sustainable base with volume tiers and time-boxed bonuses.
