We worked through the full fully-loaded cost of a B2B SDR seat in the United States in 2026, including the hidden line items most teams forget. The headline number is $70,000 to $90,000 in base pay. The real number is closer to $150,000 per seat per year.
The seven cost layers
| Cost line | Low | High |
|---|---|---|
| Base salary | $60,000 | $100,000 |
| Variable compensation (OTE) | $20,000 | $50,000 |
| Benefits and payroll taxes (25%) | $20,000 | $37,500 |
| Tooling (CRM, sales tech, data) | $3,600 | $12,000 |
| Manager time (10 to 15% of a manager) | $15,000 | $30,000 |
| Ramp cost (4 to 6 months of low output) | $10,000 | $25,000 |
| Turnover risk (50% annual) | $15,000 | $30,000 |
| Fully loaded year 1 | $143,600 | $284,500 |
The midpoint of that range, weighted to mid-market B2B SaaS in 2026, is roughly $150,000 per SDR seat per year. Some teams hit $200,000+ in high-cost cities or when ramp drags.
Layer 1: Base salary
The largest visible line item.
- SMB SDR (under $25,000 ACV): $60,000 to $80,000 base.
- Mid-market SDR ($25,000 to $100,000 ACV): $70,000 to $90,000 base.
- Enterprise BDR ($100,000+ ACV): $80,000 to $100,000 base.
Geographic adjustment: San Francisco and New York run 15 to 25 percent above these numbers. Remote-friendly companies hiring nationwide tend to anchor closer to the median.
Layer 2: Variable compensation
Most SDR comp plans are 70 percent base, 30 percent variable. The variable is OTE, not guaranteed pay, but in budgeting you should assume reps hit 80 to 100 percent of variable at full ramp.
- SMB SDR variable: $20,000 to $30,000 OTE.
- Mid-market SDR variable: $30,000 to $40,000 OTE.
- Enterprise BDR variable: $40,000 to $60,000 OTE.
Top performers exceed OTE by 20 to 50 percent, raising the cost further.
Layer 3: Benefits and payroll taxes
Industry standard for fully-loaded benefits + payroll tax in the U.S. is 25 to 30 percent of base + variable. That covers:
- Federal and state payroll taxes (FICA, FUTA, SUTA).
- Health insurance and benefits.
- 401(k) match.
- PTO and holidays.
- Workers compensation.
For a $100,000 base + variable SDR, this is $25,000 in benefits and taxes.
Layer 4: Tooling
The sales tech stack required to make an SDR effective:
| Tool category | Cost per SDR per month |
|---|---|
| CRM (Salesforce, HubSpot) | $50 to $250 |
| Sales engagement (Outreach, Salesloft, Smartlead) | $70 to $200 |
| Data provider (Apollo, ZoomInfo, Clay) | $60 to $200 |
| LinkedIn Sales Navigator | $80 to $100 |
| Calendar / meeting (Calendly, Chili Piper) | $15 to $50 |
| Conversation intelligence (Gong, Chorus) | $100 to $300 |
| Email verification + warming | $25 to $50 |
| Total per SDR per month | $400 to $1,150 |
Annual: $4,800 to $13,800 in pure tooling per SDR. Easy to overlook; consistently underbudgeted.
Layer 5: Manager time
An SDR cannot run without a manager. A working ratio is one SDR manager per 6 to 10 SDRs. At 8 SDRs to one manager, each SDR consumes 12.5 percent of a $150,000 manager.
Annual cost: $15,000 to $25,000 per SDR in manager time.
Layer 6: Ramp cost
A new SDR ramps over 4 to 6 months. During ramp, they produce 30 to 80 percent of full quota while drawing 100 percent of salary.
The ramp cost is the salary paid against output not yet earned. Math:
- Average SDR pay during ramp: $7,500 per month.
- Average output during ramp: 50 percent of full quota.
- 5-month ramp at 50 percent output: 2.5 months of lost output, or $18,750 per new SDR.
For ongoing replacement (rather than first-time hire), the cost annualizes across the SDR's tenure. A 24-month tenure spreads $18,750 across 24 months, or about $9,400 per year.
Layer 7: Turnover risk
SDR turnover is high. The 2026 averages we see across B2B SaaS:
- Annual SDR turnover: 35 to 60 percent.
- Median SDR tenure: 14 to 24 months.
Replacement cost per SDR turn:
- Sourcing and recruiting: $5,000 to $15,000 (recruiter fees, time).
- Onboarding and training: $5,000 to $15,000.
- Productivity gap during seat vacancy: $5,000 to $20,000.
- Total per turn: $15,000 to $50,000.
At 50 percent annual turnover, expected replacement cost amortizes to $15,000 to $25,000 per seat per year.
The cost-per-meeting math
A productive SDR books 8 to 15 meetings per week, or roughly 350 to 650 meetings per year at full ramp.
At a fully loaded cost of $150,000 per year:
- Lower end: $150,000 / 650 meetings = $231 per meeting.
- Higher end: $150,000 / 350 meetings = $429 per meeting.
The midpoint is around $300 per meeting. For a B2B program where the meeting-to-opportunity rate is 50 percent and the opportunity-to-close rate is 25 percent, that translates to roughly $2,400 in SDR cost per closed deal.
For ACVs above $24,000 (10x SDR cost per deal), this works. Below that, the unit economics struggle.
What an AI SDR costs by comparison
The same arithmetic for an AI SDR:
- Platform cost: $500 to $2,500 per month, or $6,000 to $30,000 per year.
- Tooling (overlaps with human SDR tooling, partly absorbed): $5,000 per year.
- Human oversight (1 SDR or operator monitoring 3 to 5 AI seats): $20,000 per year per AI seat.
- Fully loaded: $31,000 to $55,000 per AI SDR seat per year.
The cost difference is 3x to 5x in favor of AI. The meeting volume per seat is roughly the same (350 to 650 meetings per year). So the cost per meeting drops to $50 to $150.
The catch: AI-booked meetings convert to opportunities at lower rates (about 35 to 55 percent vs 50 to 70 percent for human-booked). Adjust the cost-per-pipeline-dollar comparison accordingly, and the human and AI come closer to even. AI wins on cost; humans win on quality.
When to hire vs use AI
The math is clear:
- Hire a human SDR when ACV is above $50,000, sales cycles exceed 60 days, and the work requires multi-stakeholder coordination.
- Use an AI SDR when ACV is between $5,000 and $50,000, sales cycles are short, and the work is volume-driven.
- Use both when scale and quality both matter. AI does volume, humans qualify replies, both feed AEs.
Common SDR cost mistakes
1. Budgeting only the base salary. The fully-loaded number is 2x the base. Many teams realize this only after the first quarter.
2. Underbudgeting tooling. The sales tech stack is $5,000 to $13,000 per SDR per year. Easy to overlook.
3. Ignoring ramp. A new SDR is at 50 percent of quota for 4 to 6 months. Plan for the gap.
4. Ignoring turnover. 50 percent annual turnover means every seat is rehired every two years. Budget for the cycle.
5. Comparing wrong. Comparing AI SDR cost ($30,000/year) to human SDR base salary ($70,000/year) is the wrong comparison. The right comparison is AI cost vs fully loaded human cost ($150,000/year). The gap is 5x, not 2x.
