"What's the ROI?" It's the question that makes or breaks every technology investment. Voice AI is no different. Here's how to calculate it—properly.
ROI calculation for voice AI is more than multiplying leads by value. Multiple components contribute: direct revenue impact, cost savings, efficiency gains, and quality improvements.
The Voice AI Value Equation
Direct Revenue Impact
1. Net new leads captured: Voice AI engages visitors who would otherwise leave. Engagement rate: 12-15%. Conversation-to-lead rate: 60-70%.
2. Lead quality improvement: Better qualification data improves close rates. BANT information captured automatically. Sales preparation dramatically improved.
3. Pipeline acceleration: Immediate response vs. next-day follow-up. Higher contact rates from fresh leads.
Cost Savings
- SDR/BDR efficiency: Less time qualifying cold leads. Increased output with same headcount.
- Support deflection: Pre-sale questions answered automatically.
- Marketing efficiency: Lower effective cost per lead.
Calculating Direct Revenue Impact
Net New Leads Calculation
Example:
- Monthly visitors: 50,000
- Current leads (2.5% engagement): 1,250
- Voice AI leads (14% × 65%): 4,550
- Net new leads: 3,300/month
Revenue from New Leads
- Net new leads: 3,300/month
- MQL rate 50% → 1,650 MQLs
- SQL rate 60% → 990 SQLs
- Opportunity rate 40% → 396 opportunities
- Close rate 25% → 99 new customers
- Average ACV: $12,000
- Monthly revenue: $1,188,000
Calculating Cost Savings
SDR/BDR Efficiency Gains
- Current: 5 SDRs at $50,000/month producing 250 meetings
- With voice AI: Same 5 SDRs produce 375 meetings, or 3 SDRs produce 250 meetings
- Option 1 (more output): +125 meetings = pipeline value
- Option 2 (cost reduction): $20,000/month savings
Cost Comparison: Voice AI vs. Alternatives
| Factor | 1 Additional SDR | Voice AI |
|---|---|---|
| Monthly cost | $8,000-$12,000 | $300-500 |
| Hours available | 160/month | 720/month (24/7) |
| Conversations possible | ~400 | Unlimited |
| Quality consistency | Variable | 100% consistent |
Cost per conversation:
- Chatbot: $3.33/conversation
- Voice AI: $0.89/conversation
- SDR: $25/conversation
