SDR Cost vs Outsourced AI: Real 12-Month TCO Comparison

A junior SDR (0–2 years' experience) in Western Europe negotiates between €32,000 and €38,000 gross annually in base salary, with a median around €34,500. A senior SDR (3–5 years, productive from day 30) commands a base of €45,000–€55,000, median €49,000. These figures exclude variable pay and employer contributions.

Market practice in 2026 is a variable of 15–25% of base, triggered on qualified meetings booked. For a senior at €49,000 base, that means €7,350–€12,250 in annual variable, bringing total target compensation to €56,350–€61,250. This still falls far short of the true cost to the business.

Employer social contributions in France average 42% of gross salary for a managerial employee (including supplementary pension). On a €49,000 base that adds €20,580, bringing the salaried cost before variable to €69,580.

Adding median variable (€9,800) and the associated employer contributions (€4,116), total employment cost reaches €83,496 for a senior SDR. This is the figure your accountant will see in the payroll account — not what the SDR receives in their bank account.

An SDR without tools produces no results. The minimum stack in 2026 includes: LinkedIn Sales Navigator Advanced (€1,080/year), Apollo.io Basic (€4,800/year for one enrichment licence), Lemlist or Instantly for email sequences (€600–€1,200/year), and an individual CRM licence if not covered by the company (€500–€1,800/year). Total tooling: €7,000–€8,900/year per SDR.

According to the Bridge Group SDR Metrics Report 2025, teams that under-equip their SDRs see 37% lower performance than those with a full stack. Cutting corners on tools costs more in lost productivity than it saves.

A junior SDR reaches full productivity in 4–6 months (Bridge Group). A senior gets there in 2–3 months. During ramp, the SDR generates roughly 23% of their monthly target quota. Over a 4-month junior ramp, the business pays approximately €23,000 in burdened payroll for output equivalent to €5,300 of quota delivery. The difference — €12,000–€15,000 depending on profile — is the real ramp cost, rarely captured in dashboards.

Add management overhead: a sales director spends an average of 4.3 hours per week coaching an SDR in ramp. Over 4 months that is 74 hours of senior management time, valued at €60–€90/hour depending on the manager's salary — an additional €4,440–€6,660.

Annual SDR turnover in Europe runs at approximately 22% (Bridge Group SDR Metrics Report 2025). One in five SDRs leaves within the year. Recruitment cost — job boards, agency fees if used, HR and management time — runs €8,000–€15,000, amortised over 18 months. If the SDR leaves at month 11, amortisation is not reached and a new ramp cycle begins.

Factoring in 22% annualised turnover, the per-head recruitment cost amounts to €1,760–€3,300 per year per SDR role. This line, rarely isolated in management dashboards, represents a permanent cost drain that most sales directors systematically underestimate.

Consolidating all components for a senior SDR: burdened base €69,580 + burdened variable €13,916 + tools €8,100 + ramp-up €13,500 + amortised recruitment €2,500 = total 12-month TCO: €107,596. For a junior, TCO drops to approximately €78,000, but performance is proportionally lower — the cost/output ratio is often unfavourable.

A Lead-Gene package covers: technical deployment, ICP configuration, personalised sequences, full tooling stack, AI scoring, automatic booking and reporting. Pricing ranges from €4,500–€9,500 depending on volume and complexity. Over 12 months with maintenance, total TCO is €12,000–€24,000 — 4 to 8 times less than a senior SDR, for a volume of qualified leads generally higher from month two.

An accounting firm with 28 employees (anonymised on request) deployed Lead-Gene in January 2026 in place of a planned SDR hire. Deployment cost: €6,800. First qualified meetings: day 11 post-launch. Result at month 4: 41 qualified meetings booked, 9 new client mandates signed at an average annual fee of €4,200. Additional revenue generated: €37,800. ROI at month 4: 456%. The SDR hire was permanently shelved.

This case illustrates the typical pattern observed across our 127 active clients: break-even is reached between months 2 and 5 depending on sector and average contract value. From month 6, every euro invested in the machine statistically generates €6–€11 of potential revenue in the pipeline.
