Frequently Asked Questions
How much does a single missed call really cost?
A missed call costs far more than lost immediate revenue. When you factor in lifetime customer value, referral potential, and competitor capture, a single missed call can represent $500-$2,000+ in lost revenue depending on your industry.
What percentage of missed callers actually call back?
Studies show only 20-30% of callers who reach voicemail will call back. The remaining 70-80% move on to the next business they find, meaning most missed calls are permanently lost opportunities.
How does missed call volume affect lead conversion?
Speed-to-answer is a top factor in lead conversion. Businesses that answer within 3 rings convert 30-50% more leads than those who miss calls and rely on callbacks. Even a 10-minute delay reduces conversion rates by 80%.
What's the best way to reduce missed call costs?
Combine online booking (so callers aren't needed), automated call handling for overflow, and SMS auto-replies when calls are missed. Together, these strategies can recover 60-80% of otherwise lost revenue.
Our Methodology
Missed call costs are calculated by multiplying your missed call volume by average booking value and customer lifetime value. We apply industry callback rates (only 20-30% of callers retry) and competitor capture rates to quantify the true revenue impact of every unanswered call across a month and year.
Callback Rate
Only 20-30% of missed callers call back
Competitor Capture
85% of callers who can't reach you try a competitor
Lifetime Value Factor
Each new client worth 8-12x first appointment value
Peak Hour Miss Rate
40-60% of missed calls happen during peak hours
Based on telecommunications research and service industry call analytics
“This calculator was a wake-up call. We were missing 12 calls a day during peak hours—that's over $8,000/month in lost bookings. Once we saw the numbers, we fixed it immediately.”
