An entry-level SDR in the United States costs between USD 8,000 and USD 15,000 per month when you factor in salary, commission, benefits, tools, training, and management overhead (Salesforce State of Sales 2026). For a team of three SDRs, that is USD 288,000 to USD 540,000 per year. And the average tenure? Nine to twelve months before burnout or promotion, meaning you are constantly hiring and retraining. The cost of turnover adds another 30-50% of annual salary per replacement, plus the 3-4 months of reduced productivity while the new hire ramps up. When you calculate the total cost of ownership for a human SDR team over 12 months, the numbers are staggering and often hidden from traditional budget calculations. Most companies look only at base salary and miss the 50-70% in additional costs that come with each hire.

What you actually pay for a human SDR
The visible costs are just the beginning. Base salary (USD 60,000-80,000), commission and bonus (USD 20,000-40,000), benefits and payroll tax (USD 15,000-25,000), CRM and tooling (USD 5,000-10,000), training and ramp-up time (3-4 months at full salary with zero pipeline), and management cost (an SDR manager for every 6-8 reps). When you add it up, the fully loaded cost of a single SDR is USD 100,000-180,000 per year. Most B2B companies underestimate this total by 40-60% because they only look at base salary and ignore the overhead costs that double the real expense.

For a team of five, the annual savings exceed USD 400,000 when comparing fully loaded costs against AI SDR subscription fees, while delivering 3-5x more outreach volume.
Output comparison: AI SDR vs human SDR
A human SDR typically handles 50-100 outbound activities per day and books 5-15 qualified meetings per month on average. An AI SDR handles 500+ personalized conversations per day and books 3-5x more meetings. The AI never calls in sick, never takes vacation, and never burns out. It maintains consistent quality across every conversation regardless of volume. When you calculate cost per qualified meeting, the AI SDR delivers at approximately USD 112 per meeting versus USD 340 for an outsourced SDR agency and USD 800+ for an in-house hire when fully loaded costs are included.
When to hire humans vs deploy AI
The best B2B sales teams use a hybrid model: AI SDR handles top-of-funnel outreach, qualification, and meeting booking autonomously. Human SDRs and AEs handle demos, negotiations, and closing high-value opportunities. This model delivers 5x more pipeline at 67% lower cost per qualified lead compared to human-only teams, according to CloseDealsAI customer data. The AI handles the repetitive, high-volume work while humans focus on high-value conversations that build relationships and close complex deals. The result is a sales team that scales without linearly increasing headcount.
