How We Calculate Your Missed Call Cost

This calculator uses three key variables: your industry's average miss rate (how often calls go unanswered), your average conversion rate (how often a connected call becomes a customer), and your average deal value (revenue per transaction). The formula:

Monthly Revenue Lost = (Calls/Day × 38% miss rate × 22 days) × 15% conversion × Avg Deal Value

Industry Benchmarks Used

These defaults are based on industry research and typical SMB performance data:

Industry Avg Deal Value Miss Rate Conversion Cost per Missed Call
Property Management $1,500 38% 15% $225
Auto Dealership $2,500 38% 15% $375
Dental Practice $350 38% 15% $52.50
Legal / Law Firm $500 38% 15% $75
HVAC $250 38% 15% $37.50
Plumbing $200 38% 15% $30

Why 38% Miss Rate?

Research consistently shows that small and medium businesses miss approximately 38% of inbound calls during business hours. During evenings and weekends, that number climbs to over 60%. Calls missed after hours are nearly always from high-intent prospects who called your competitor within the next 90 seconds.

Why 15% Conversion Rate?

Industry averages for inbound calls converting to booked appointments or closed deals range from 10–25%. We use 15% as a conservative baseline. If you run a tight operation with a strong close process, your actual number may be higher — which means your true loss is larger than the calculator shows.

Frequently Asked Questions

How much does a missed call really cost a small business?
It depends on your industry and average deal size. A missed call for an auto dealership costs roughly $375 in lost revenue (15% close rate × $2,500 deal value). An HVAC company loses about $37.50 per missed call. At 38% miss rate on 15 calls per day, that adds up to $18,720–$124,800 per year depending on your industry. Use the calculator above to see your specific number.
What percentage of small business calls go unanswered?
Studies consistently show approximately 38% of small business calls go unanswered during business hours, and nearly 62% outside of business hours (evenings, weekends, holidays). The average SMB misses about 8 out of every 22 calls per day. Most of those callers don't leave a voicemail — they call the next business on Google.
How accurate is this missed call calculator?
The calculator uses conservative industry averages: 38% miss rate, 15% conversion rate, and standard deal values by vertical. Your actual numbers may be higher or lower. The goal is to give you a directionally correct estimate. If you've tracked your own conversion rates, update the "Average Deal Value" field to reflect your true revenue per appointment — the miss rate and conversion math stays the same.
What's the ROI of answering every call with AI?
For most local businesses, capturing even 50% of missed calls delivers 10x–100x ROI on AI answering services. A dental office missing 5 calls per day loses about $5,775/month. NeverClosed at $49/month captures ~80% of those calls and recovers ~$4,620/month — that's a 94x return on the monthly cost. The calculator's ROI section shows this math for your specific numbers.
