Costs and pricing
What do affiliate marketing costs and pricing look like for a UK brand?
A guide to affiliate marketing costs and pricing for UK brands, covering network fees, commission, the ICO data protection fee, VAT and paid media benchmarks.
What to take away
- Affiliate marketing is usually priced as a share of tracked sale value rather than a flat retainer, so most of the cost scales with revenue. A brand paying a 10% commission on £40,000 of monthly affiliate sales spends £4,000 a month before network or software fees, as an illustrative example.
- Fixed costs sit around the edges: network or software fees, the ICO data protection fee where you process personal data, and VAT once you pass the registration threshold.
- Override or tier fees are the line item brands most often miss when comparing platforms, and they can add several percentage points to the effective commission rate.
- Budget on total cost per acquired customer, not on headline commission. A programme that looks expensive on rate can still be cheap per order if it converts well.
- Build the model before you sign. A written budget forces the commercial assumptions into the open, which is what you want when a finance director asks why affiliate spend rose faster than revenue.
The rest of this guide sets out each cost line, how the pricing models differ, and how to turn the numbers into a budget you can defend at a board meeting.
Fixed costs to expect
Every affiliate programme carries costs that do not move with sales. These are the easiest to forecast and the easiest to forget.
Platform and network fees
Affiliate software is usually charged either as a monthly platform fee or as a percentage of tracked revenue, and sometimes both. A network that charges 30% of the commission it handles on a £4,000 commission bill takes £1,200 a month, as a labelled illustrative example.
Self-hosted software shifts the model towards a licence fee plus payment processing. That can suit high-volume retailers, but it moves fraud screening, tracking maintenance and partner recruitment back onto your own team, which is a real cost even if it never appears on an invoice.
Before comparing quotes, it helps to understand how each commercial model behaves as volume grows. Our guide to affiliate marketing pricing models in England walks through revenue share, flat fee and hybrid structures side by side.
Tenancy and setup fees
Networks often charge a tenancy fee for hosting your programme on their platform, plus a one-off setup or integration charge at launch. A tenancy fee of £500 to £1,500 a month is common in mid-market retail, as a labelled illustrative example, though it is often bundled into the override.
Ask whether the tenancy fee is capped once commission volume passes a threshold. Many contracts waive it above an agreed level, and a supplier who will not move on the headline rate may still move here.
Setup fees cover tag implementation, tracking validation and account configuration. Budget for them in month one rather than spreading them across the year, because they fall due before any revenue arrives.
Data protection and compliance
If your programme involves processing personal data, for example holding publisher contact records or passing order data to a network, you will usually need to pay the ICO data protection fee. The tiers are banded by organisation size and turnover, so a small affiliate team pays less than a large retailer.
The data protection fee guidance for organisations explains who must pay and how the bands work. Treat it as a fixed annual cost, not a variable one.
VAT on commission and fees
Commission paid to UK publishers is generally a business-to-business supply, and VAT treatment depends on how the publisher is registered and where it sits. Once your own taxable turnover crosses the threshold, you must register and account for VAT on your supplies.
GOV.UK sets out the consequences in its guidance on what registering for VAT may mean for your business. For a retailer, registration changes the effective cost of every fee you pay, because you may be able to reclaim input tax on platform charges.
Agency and management fees
Outsourced programme management is usually charged as a retainer, a percentage of commission, or a blend of both. A retainer of £1,500 to £4,000 a month plus 10% of commission is a structure quoted in the market, as a labelled illustrative example.
The trade-off is straightforward. An agency brings publisher relationships and campaign capacity you would otherwise have to build, but it adds a layer of cost between your budget and the sale.
If you keep management in-house, count the salary time honestly. A partner manager, a tracking specialist and a finance contact for reconciliation are real roles, even when one person covers all three.
Variable costs and commission
Commission is the largest single line in most affiliate budgets and the one with the widest range.
Typical commission ranges
Rates vary by sector and margin. As labelled illustrative examples, a fashion retailer might pay 5% to 10% of order value, an electronics retailer 1% to 4%, and a software business 15% to 30% of first-year contract value. None of these are rules, only starting points for a negotiation.
Cookie window matters as much as rate. A 30-day window on a considered purchase costs more in practice than a 7-day window on a repeat grocery order, even at the same headline percentage.
Refund and cancellation rates feed back into cost. If 12% of affiliate orders are returned, the effective commission per retained sale is roughly 14% higher than the headline rate, as a labelled illustrative example. Build that clawback assumption into your model from the start.
Overrides and tier fees
Many networks add an override on top of publisher commission. A 30% override on a £4,000 commission bill adds £1,200 a month, as a labelled illustrative example. Overrides are negotiable, particularly once you can show a track record of volume.
Tier fees work in the other direction. Publishers who hit agreed sales bands may earn a higher rate on incremental volume, which raises the blended cost but only on sales you would not otherwise have made.
Watch for escalation clauses tied to a group of top publishers. A rate that rises from 8% to 11% once a publisher passes a monthly threshold can lift your blended cost faster than revenue grows, so model the ceiling before agreeing to it.
Publisher incentives and placements
Voucher code and cashback publishers often negotiate a placement fee on top of commission. A homepage slot or a dedicated email may be quoted at £1,000 to £5,000 for a campaign window, as a labelled illustrative example.
Launch bonuses are common when a programme is new and needs volume quickly. A £5 bonus per new customer for the first three months is a typical nudge, as a labelled illustrative example, and it should sit in the budget rather than in a contingency.
Exclusivity costs more. Agreeing a rate that no other publisher in the same category can match buys attention, but it also commits you to a floor price for the length of the term.
Payment, tracking and reconciliation
Payment processing, currency conversion and reconciliation all carry administrative cost. If you pay publishers in euros or dollars, budget for conversion spread and for the staff time spent chasing mismatched transactions.
Tracking failures are the hidden cost that matters most. A broken tag means unattributed sales, disputed invoices and publisher trust lost. Our article on affiliate marketing hidden costs in England covers the operational leaks that never appear in a rate card.
Benchmarking against paid media
Affiliate rarely sits alone in a marketing budget, so it is worth knowing what the alternatives cost.
LinkedIn publishes its advertising rates, which gives a useful public reference point for business-to-business paid media. The LinkedIn advertising costs and pricing page shows how cost per click and cost per impression are structured on that platform.
If a LinkedIn campaign costs £8 per click and converts at 2%, the cost per acquisition is £400 before any follow-up, as a labelled illustrative example. That is the number to compare against your affiliate cost per acquisition, not the commission rate.
Paid search is the closer comparison for most retailers, because buyer intent is similar. As a labelled illustrative example, a non-brand campaign at £1.20 per click converting at 4% lands at £30 per acquisition before returns and refunds are deducted.
Affiliate usually wins on a pure cost-per-sale basis because you pay after the sale. Paid media wins on control and on reach into audiences no publisher covers. Most mature brands run both and compare them on the same contribution metric.
Comparison table

Building a defensible budget
A budget is only useful if it survives contact with the finance team.
Start from revenue, not cost
Model affiliate revenue first, then apply commission. If you expect £40,000 of monthly affiliate sales at a 10% blended rate, commission is £4,000, as a labelled illustrative example. Add override, platform fee and processing to reach a total programme cost.
Separate acquisition from retention
Commission paid on a returning customer who would have bought anyway is a retention cost, not an acquisition cost. Segregate new-customer commission in your reporting so you can judge whether the programme is genuinely adding revenue.
Set a cost-per-acquisition ceiling
Decide the maximum you will pay to acquire a customer, then work backwards to the commission rate you can offer. This keeps negotiations anchored to your economics rather than to a competitor's published rate.
Our affiliate marketing budget template in England gives you a starting structure with the rows most teams need, including the fixed and variable lines above.
Phase the first year
Costs do not arrive evenly. Setup, tag integration and the first month of tenancy land before meaningful revenue, so months one and two are typically the heaviest.
Assume a three to six month ramp before commission stabilises. Hold a contingency of 10% to 15% of planned spend for tracking fixes and publisher incentives, and treat launch bonuses as part of the plan rather than as an exception.
Measuring whether it pays
Cost control only matters if the programme returns more than it consumes.
Return on investment in affiliate is best measured on incremental profit, not on total revenue. A programme can grow revenue and still destroy margin if commission is paid on sales that would have happened anyway.
Run a holdout test where you can. Suppress a share of your audience from affiliate exposure and compare order rates. That gives you an incrementality estimate grounded in your own data rather than a network's reporting.
The affiliate marketing return on investment guide sets out how to calculate contribution after commission, fees and refunds, which is the figure your finance director will actually use.
Market context for planning
The size and shape of the UK business base affects how much affiliate capacity exists to work with. The Office for National Statistics business statistics collection publishes counts and activity data for UK businesses, which is a reasonable starting point for sizing a market.
Use those counts to sanity-check your publisher plan. If you need 200 active partners to hit a revenue target, compare that figure against the number of businesses operating in your category before you commit to it.
Regulation also shapes cost. The Digital Markets, Competition and Consumers Act 2024 gives the competition authority new powers over unfair commercial practices and subscription traps, both of which touch affiliate promotions and comparison sites.
Compliance work is a cost line. Budget for reviewing publisher claims, disclosure wording and pricing statements, because a single enforcement action costs far more than the review.
Looking further ahead, our piece on affiliate marketing trends and outlook for England in 2027 covers how platform consolidation and disclosure rules may shift the cost base over the next planning cycle.
Common questions
Is affiliate marketing cheaper than paid search?
On a cost-per-sale basis, usually yes, because commission is only paid after a tracked sale. On total programme cost, not necessarily, because fixed platform fees and overrides apply regardless of volume. Compare both on cost per acquired customer.
What percentage should I pay in commission?
There is no standard rate. Start from your gross margin and your maximum acceptable cost per acquisition, then set a rate that leaves room for override and processing. Rates commonly range from low single digits in low-margin retail to 30% in software, but treat any figure as a starting point for negotiation.
Do I need to pay the ICO data protection fee?
If you process personal data and are not exempt, yes. The fee is banded by organisation size and is payable annually, and it applies to affiliate teams as much as to any other business function.
What is the biggest hidden cost in an affiliate programme?
Unattributed sales caused by tracking failures. They show up as disputed invoices, duplicated commission and publisher churn, and they are difficult to recover once trust has gone. Regular tag testing is cheap by comparison.
