An affiliate agency usually costs a monthly retainer, sometimes with a performance fee on top. But the agency fee is only one of three costs. You also pay your affiliate platform and your partners. This guide explains all three, how agencies price their work, and what a full month looks like in practice, for brands selling in the UK or the US.
The three costs of an affiliate programme
Before comparing agency quotes, separate what you pay the agency from what you would pay anyway.
| Cost | Who you pay | How it’s charged |
|---|---|---|
| Partner commissions and placements | Publishers, creators, cashback and deal sites | A percentage of each sale (CPA), and sometimes fixed fees for guaranteed placements |
| Platform or network fees | The network or tracking platform (for example Awin, impact.com, CJ, Rakuten) | A monthly fee plus a percentage of each sale or of the commission |
| Agency fee | The agency that runs the programme | A retainer, a performance fee, or a mix (see below) |
Only the third line is the agency’s fee. Partner and platform costs exist whether you run the programme yourself or hire someone. A good agency should lower them over time, by cutting partners who don’t add new sales and negotiating better placements.
What platforms charge
Some platforms now publish their entry prices, which makes this part easy to estimate.
- Awin (UK): the Access plan is £99 + VAT a month plus a 3.5% tracking fee on each sale. Accelerate starts from £199 + VAT a month with a 2.5% tracking fee. In the US, Access is $49 a month plus 3.5%. (Awin UK pricing, Awin US pricing)
- impact.com: the self-serve Starter plan is $30 a month or 2.5% of partner-driven revenue, whichever is greater, and is only available on certain ecommerce platforms such as Shopify and WooCommerce. Larger plans are quoted. (impact.com pricing, Starter billing)
- CJ and Rakuten don’t publish rate cards. Expect a negotiated setup fee and a percentage on top of commissions.
The tracking fee is charged on the sale value, not on the commission. On a £100 sale with a 6% commission, your partner gets £6 and Awin Access takes £3.50 on top.
How affiliate agencies price their work
1. Monthly retainer
The most common model. You pay a fixed fee for an agreed scope: day-to-day management, recruitment, reporting and a set number of campaigns. It’s predictable, and the agency is paid for work that doesn’t show up in sales straight away, such as recruiting new partners.
2. Performance fee
The agency takes a percentage of affiliate revenue or of the commission you pay. It sounds lower-risk, but check what it’s calculated on. If voucher sites and brand-bidding partners count toward the total, the agency earns on sales you would have made anyway. Our guide to protecting your affiliate margin covers what to exclude.
3. Hybrid
A lower retainer plus a bonus for hitting agreed targets, such as new-customer sales or revenue from new partners. This is often the fairest model once a programme has a few months of data.
4. One-off fees
Some agencies charge separately for a launch (platform setup, commission structure, first recruitment push) or for an audit of an existing programme. An audit is a good way to test an agency before committing to a retainer.
Hourly rates are less common for ongoing management, but they’re a useful benchmark. US agencies typically charge $100 to $150 an hour, according to DesignRush.
What makes an agency cost more or less
- Programme stage. Launching from scratch takes more work in the first three months than taking over a programme that already runs.
- Number of markets. The UK, US and Europe each have different publishers, networks and seasonal peaks. Each market adds recruitment and reporting time.
- Partner mix. Editorial publishers and creators need more hands-on work (briefs, content approvals, placement negotiation) than cashback and deal sites.
- Recruitment targets. Adding 10 vetted partners a month costs more than maintaining the ones you have.
- Payments and admin. If the agency also coordinates fixed-fee invoices and partner payments, expect that in the scope.
- Language and time zones. If your team is outside the UK or US, you may need reporting in your own language and someone working Western hours.
A worked example
Here’s an illustrative month for a UK brand on Awin Accelerate, with £50,000 of affiliate sales and a 7% average commission. Your own figures will differ.
| Item | Cost |
|---|---|
| Partner commissions (7% of £50,000) | £3,500 |
| Awin tracking fee (2.5% of £50,000) | £1,250 |
| Awin platform fee (from) | £199 |
| Total before agency fee | £4,949 (about 10% of affiliate sales) |
| Agency fee | Quoted to scope |
The agency fee sits on top. It depends on the scope of work, the markets you sell in, the resource the programme needs and its size, which is why most agencies quote after an audit rather than from a rate card. The bigger lever is what the £50,000 is made of: sales from new customers through trusted publishers are worth far more than sales that would have happened anyway.
UK and US: what’s different
- Currency and plans. Platform prices are set per region. Awin’s entry plan is £99 + VAT in the UK and $49 in the US, with the same 3.5% tracking fee.
- Scale. US programmes usually have a bigger pool of publishers and creators, so recruitment can take more time, and more budget goes to fixed-fee placements on large editorial sites.
- Seasonality. Both markets peak around Black Friday. The US also builds around Prime Day, and the UK has its own retail calendar, so agree up front how many campaigns the fee covers.
Questions to ask before you sign
- What exactly does the fee include, and what’s billed as extra?
- What’s the minimum term, and how do we leave?
- Who owns the platform account and the partner relationships? It should be you.
- If there’s a performance fee, which sales does it count, and are voucher and brand-bidding sales excluded?
- Does the agency receive fees from networks or publishers? If so, how is that disclosed?
- What will the monthly report show, and in which language?
Is an agency worth it?
An agency usually makes sense when you don’t have an experienced affiliate manager in the market you’re selling to, or when you want to launch quickly with existing partner relationships. As a programme grows, some brands bring management in-house. The useful comparison is the agency fee against the cost of hiring and training someone who already knows the publishers. We explain the agency model in more detail in what is an OPM agency?, and how partner deals are priced in CPA, fixed fees or hybrid.

FAQ
How much does an affiliate agency cost per month?
Most charge a monthly retainer agreed to the scope, sometimes with a performance bonus. On top of that you pay partner commissions and platform fees, which together are often larger than the agency fee.
Is a performance-only agency cheaper?
Not always. A fee on total affiliate revenue can reward sales you would have made anyway, such as voucher and brand-bidding sales. Check what the percentage is calculated on.
Do I need a network if I hire an agency?
Yes, you still need a tracking platform or network. A good agency recommends one that fits your markets and sales channels, and sets it up in your name.
How long before an affiliate programme pays back?
Expect a few months to build momentum. That’s why many agencies, including us, suggest starting with at least a quarter.
