What "Fair" Means From Both Sides of the Commission Rate
A sales commission rate that is fair to only one party is not a sustainable structure — it either undervalues the SDR (who leaves when they find a better offer) or overvalues the SDR contribution (which makes the agency unprofitable at volume). "Fair" in commission rates means two things simultaneously: the rate leaves the agency with a positive net margin on every verified close, and the rate produces a realistic OTE that attracts and retains competent SDRs.
Does the rate leave sustainable margin after commission?
The commission rate must produce a positive net margin on every verified close — at minimum 15% net after commission. Below 15% net margin at volume, commission costs make the business unprofitable when pipeline pressure increases and close rates drop temporarily. The rate is a mathematical output of margin, not a negotiating position.
Does the rate produce realistic OTE at expected close rates?
The commission rate, applied to expected monthly closes at average deal values, should produce an OTE that is competitive for cold calling work with no base salary. Below £800–£1,000/month OTE at typical performance, the role is not financially viable for most SDRs — they will seek guaranteed income elsewhere.
The fairness convergence point: When you calculate the sustainable commission rate from margin and separately calculate the minimum rate that produces a viable OTE, the two figures should overlap. If they do not — if the margin-sustainable rate produces an unviable OTE, or if the viable-OTE rate makes the agency unprofitable — the underlying problem is either the deal value is too low for the niche, the margin is too thin to support SDR commission, or the expected close rate is too optimistic. Adjusting the rate alone cannot fix those underlying mismatches.
The Margin-First Rate Calculation — How to Find Your Number
Before selecting a commission rate, calculate your net margin on a typical close in your target niche. Commission is a cost of revenue — it must be set as a percentage of what the deal actually leaves the agency, not as a competitive benchmark or a round number that "feels fair."
The table shows the rate pattern that emerges from the margin-first approach: lower rates on lower-value niches (10% on locksmiths and cleaners) and higher rates on premium niches (18% on roofers and contractors). This is not arbitrary generosity — it is the natural result of applying a consistent net-margin-after-commission floor across different deal value brackets. The same £270 commission on a £1,800 plumber deal leaves 20% net. On a £750 locksmith deal at 15%, commission would be £113 and net margin would only be 22% — still acceptable but the SDR OTE at typical close rates would be below the viable threshold.

Why Tiered Commission Rates Are Fairer Than Flat Rates — From Both Perspectives
No incentive to push for premium deals
Premium closes earn disproportionately more
The tiered rate conversation with an SDR candidate: The first instinct of an SDR seeing a tiered structure is to compare the bottom tier (10%) to a competitor's flat rate (15%) and conclude the role pays less. The correct comparison is: what commission does a roofer close earn? At 18% on a £3,200 roofer deal = £576 vs 15% flat = £480. Tiered structures pay more on the closes that require more skill — and less on the closes that require less. An SDR who understands this welcomes tiered rates because they directly reward the premium conversation capability that distinguishes a strong SDR from an average one.
How to Present the Commission Rate to an SDR Candidate
When to Review and Adjust Your Commission Rate
Consistent SDR attrition citing pay
If SDRs are consistently leaving citing low commission earnings despite hitting quota, the rate may be too low relative to the deal values in your niche. Before raising the rate, calculate the OTE at expected close rates — if it is below £1,000/month, the rate needs adjustment or the niche needs upgrading to higher-value targets.
Deal values have increased significantly
If your average deal value has increased from £1,400 to £2,200 in the last 12 months (because you moved to higher-margin services), a flat 15% rate now produces much higher commission — and may have crossed into territory where your net margin is under pressure. Review whether the flat rate needs a ceiling or whether tiered rates are more appropriate.
Niche rotation to premium campaigns
When moving an SDR from a mid-tier niche (plumbers at 15%) to a premium niche (roofers), review whether the rate needs to adjust. Often it does — 18% on a £3,000 roofer deal is the appropriate tier rate at that deal value. The niche rotation conversation is also the rate adjustment conversation.
Net margin has been compressed by rising costs
If your agency's net margin on a typical website project has dropped from 40% to 25% due to rising delivery costs, the commission rate that was sustainable at 40% margin (15% at £1,800 = £270 commission, leaving £450 net) may not be sustainable at 25% margin (£270 commission on £450 margin leaves only £180 net — 10%). Margin changes require rate reviews with 30 days notice to SDRs.
Never change a commission rate mid-campaign without 30 days written notice. An SDR who started a campaign at 15% commission who finds it changed to 12% in month 3 — even with 30 days notice — has a legitimate grievance if the rate reduction was not anticipated at onboarding. Commission rate changes are always more acceptable when (1) they were discussed as a possibility at hire, (2) they come with a niche change that affects deal values, or (3) they are increases rather than reductions.

Frequently Asked Questions
What is a fair sales commission rate for web agency SDRs in 2026?
Fair sales commission rates for web agency SDRs depend on niche and deal value: 8–10% for low-value niches (locksmiths, basic cleaner sites with £600–£950 average deals), 12% for mid-tier niches (electricians, landscapers with £1,100–£1,500 average deals), 15% for standard mid-tier (plumbers with £1,400–£2,200 average deals), and 18% for premium niches (roofers, contractors with £2,200–£4,500 average deals). The rule: commission rate should leave the agency with at least 15–20% net margin after commission on a typical close.
How do you calculate the right commission rate for your web agency?
Start with your net margin on a typical close in your target niche. For a £1,800 plumber site with 35% gross margin (£630 margin), a 15% commission rate costs £270 — leaving £360 net (20%). That is sustainable. A 25% rate would cost £450 — leaving only £180 net (10%) — too thin at volume. Also check the OTE test: the rate × expected monthly closes × average deal value should produce at least £1,000/month OTE. If the margin-sustainable rate produces below £1,000 OTE, the niche deal values are too low for a viable commission-only SDR structure.
Are tiered commission rates fairer than flat rates?
Yes — from both the agency and SDR perspective. Tiered rates (lower % on lower-value deals, higher % on premium deals) reward the premium conversation skill required to close higher-value businesses more than flat rates do. A £3,200 roofer close at 18% earns £576 — 7.7x more than a £750 locksmith close at 10% (£75). Under a flat 15%, the same comparison produces 4.3x difference. Tiered rates also cost the agency less in commission percentage on lower-value closes while improving margin sustainability. They are structurally better than flat rates for multi-niche campaigns.
Why don't SaaS SDR commission benchmarks apply to web agencies?
SaaS SDR commission benchmarks (typically 10–20% of variable component on top of a $55k–$75k base salary) are calibrated to a completely different pay structure. The commission component in SaaS SDR roles is a top-up to a substantial guaranteed base — the commission percentage only needs to produce additional motivation, not the SDR's entire income. Web agency SDRs typically have no or minimal base salary — commission is their primary or sole earnings. The percentage must be high enough to produce a viable monthly income at expected close rates, which requires a fundamentally different calculation than enterprise SaaS benchmarks.
