Sales Development Representatives (SDRs) are the top of your revenue funnel — but hiring one involves more cost than most founders expect. Between compensation, tools, ramp time, and the risk of a bad hire, the true cost of an SDR often exceeds $100,000 in the first year.
Here's a complete breakdown so you can budget accurately and decide whether to hire directly or work with an SDR recruiting agency.
SDR Compensation Costs
Base salary
US SDR base salaries in 2026 typically fall between $45,000–$65,000, varying by location, industry, and company stage. San Francisco and New York command premiums; remote roles often pay national averages.
Commission and OTE
Most SDRs earn commission on meetings booked, pipeline generated, or deals closed by AEs they sourced. On-target earnings (OTE) usually land at $60,000–$85,000 total. Structure commission to reward qualified meetings, not just volume.
Benefits and payroll taxes
Add 20–30% on top of base salary for health insurance, payroll taxes, 401(k), and PTO. On a $55,000 base, that's roughly $11,000–$16,500 annually in additional employer costs.
Tools and Technology
Each SDR typically needs:
- CRM seat (Salesforce, HubSpot) — $50–$150/month
- Sales engagement platform (Outreach, Salesloft) — $100–$200/month
- Data enrichment (ZoomInfo, Apollo) — $100–$300/month shared across team
- Dialer and email tracking — $50–$100/month
Budget $300–$600/month per SDR for tooling, depending on your stack.
Ramp Time and Productivity Gap
SDRs rarely produce meaningful pipeline in month one. Expect:
- Month 1: Training, shadowing — minimal output
- Month 2: First meetings booked — partial productivity
- Month 3: Approaching full quota — ~70–80% productivity
- Month 4+: Full productivity
During ramp, you're paying full salary for partial output. On a $55K base, three months of ramp costs roughly $13,750 in salary alone before the SDR pays for themselves.
Recruiting and Hiring Costs
- DIY hiring: Job boards ($200–500), interview time (20–40 hours of manager time), opportunity cost of delayed pipeline
- Sales recruiting agency: Placement fee (often 15–25% of first-year OTE) but faster time-to-fill and pre-vetted candidates
- Bad hire cost: If an SDR fails at month 3, you've spent ~$25,000+ with nothing to show for it
Turnover Risk
SDR roles have high turnover — often 25–35% annually. Each departure triggers another recruiting cycle, another ramp period, and lost pipeline momentum. Investing in better upfront vetting reduces this cycle significantly.
Total First-Year Cost Estimate
- Base salary: $45,000–$65,000
- Commission: $15,000–$25,000
- Benefits/taxes: $11,000–$16,500
- Tools: $3,600–$7,200
- Recruiting (if applicable): $5,000–$20,000
- Total: ~$80,000–$130,000 per SDR in year one
How to Reduce SDR Hiring Costs
- Hire candidates with relevant industry experience to shorten ramp
- Use structured role-play interviews to avoid bad hires
- Work with an SDR recruiting specialist who pre-screens for outbound skills
- Choose agencies with replacement guarantees to eliminate bad-hire risk
RepReady places vetted SDRs and BDRs with a 30-day replacement guarantee — so if the fit isn't right, you don't eat the full cost of a failed hire.
