AI SDR ROI Calculator (2026): Calculate Your AI vs Human SDR Return
Calculate your AI vs human SDR ROI with this step-by-step calculator. Input your lead volume, team size, and conversion rates to see projected cost per meeting, cost per SQL, and 12-month ROI.

Use this calculator to estimate the ROI of deploying AI sales agents versus hiring human SDRs. Input your specific numbers and see projected cost per meeting, cost per SQL, cost per closed deal, and 12-month ROI across three scenarios.
Step 1: Input Your Numbers
| Input | Your Number | Notes |
|---|---|---|
| Monthly inbound leads | _______ | Website forms, phone calls, chat |
| Monthly outbound prospects | _______ | Cold lists, partner referrals |
| Average deal size (annual) | $_______ | Revenue per closed customer |
| Current human SDR monthly cost | $_______ | Salary + benefits + tools + management |
| AI agent monthly cost | $_______ | Platform subscription + setup (amortized) |
Step 2: Apply Conversion Benchmarks
| Scenario | AI Response Rate | AI Contact Rate | AI Booking Rate | Human Booking Rate |
|---|---|---|---|---|
| Conservative | 60% | 40% | 15% | 12% |
| Base case | 75% | 50% | 25% | 18% |
| Strong case | 85% | 60% | 35% | 25% |
Step3: Calculate Projected Returns
For Each Scenario:
AI meetings booked = (Inbound + Outbound) × AI response rate × AI contact rate × AI booking rate
Human meetings booked = (Inbound + Outbound) × Human response rate × Human contact rate × Human booking rate
AI cost per meeting = AI monthly cost / AI meetings booked
Human cost per meeting = Human monthly cost / Human meetings booked
12-Month ROI:
AI 12-month ROI = (AI meetings × close rate × deal size - AI 12-month cost) / AI 12-month cost
Human 12-month ROI = (Human meetings × close rate × deal size - Human 12-month cost) / Human 12-month cost
Worked Example: 500 Leads/Month
| Input | Value |
|---|---|
| Monthly inbound leads | 300 |
| Monthly outbound prospects | 200 |
| Average deal size | $5,000/year |
| Human SDR monthly cost | $6,500 |
| AI agent monthly cost | $1,000 |
| Scenario | AI Meetings/Mo | Human Meetings/Mo | AI Cost/Meeting | Human Cost/Meeting | AI 12-Mo ROI | Human 12-Mo ROI |
|---|---|---|---|---|---|---|
| Conservative | 36 | 18 | $28 | $361 | 22x | 1.8x |
| Base case | 63 | 32 | $16 | $203 | 38x | 3.2x |
| Strong case | 90 | 45 | $11 | $144 | 53x | 4.5x |
Cost Per SQL Comparison
Cost per SQL = Cost per meeting × (1 - disqualification rate)
| Scenario | AI Cost/SQL | Human Cost/SQL | AI Advantage |
|---|---|---|---|
| Conservative | $35 | $450 | 13x cheaper |
| Base case | $20 | $250 | 13x cheaper |
| Strong case | $14 | $180 | 13x cheaper |
Cost Per Closed Deal Comparison
Cost per closed deal = Cost per SQL × (1 / close rate)
| Scenario | AI Cost/Deal | Human Cost/Deal | AI Advantage |
|---|---|---|---|
| Conservative | $175 | $2,250 | 13x cheaper |
| Base case | $100 | $1,250 | 13x cheaper |
| Strong case | $70 | $900 | 13x cheaper |
Adjusting for Your Specific Factors
Higher AI ROI If:
- High inbound lead volume (200+ leads/month)
- Short sales cycle (close within 30 days)
- Multiple products/services to cross-sell
- After-hours lead capture is critical
Lower AI ROI If:
- Very low lead volume (under 50/month)
- Complex enterprise sales (6+ month cycle)
- High-ACV deals ($100K+) requiring human relationship building
- Regulated industry requiring human oversight on all communications
FAQ
Q: How accurate is this calculator? A: The calculator provides benchmarks based on data from thousands of AI sales agent deployments. Your actual results will depend on lead quality, sales cycle, and offer. Most companies see results within 20–30% of the base case.
Q: What's the minimum lead volume for AI to make sense? A: Any company processing 50+ leads/month can benefit from AI. The ROI increases significantly at 200+ leads/month where human SDRs can't keep up.
Q: How long until I see results? A: Most companies see initial results within 2–4 weeks of deployment. Full ROI typically takes 60–90 days to materialize.
Q: Should I replace human SDRs entirely with AI? A: For most companies, the best model is hybrid: AI for speed, volume, and qualification; humans for complex discovery, relationship building, and high-value deals.
