What is the average value of a missed call for a small business?

The average missed call costs a small business somewhere between $100 and $500 in lost revenue, though for service businesses like plumbers, roofers, or lawyers, a single unanswered call can represent thousands of dollars in potential work. These numbers aren't arbitrary — they come from combining average customer lifetime value with realistic conversion rates. If your average job is worth $300 and you convert roughly one in three callers who actually reach you, each missed call represents about $100 in lost revenue before you even factor in repeat business.

The harder number to calculate is cumulative loss. A small business missing just three calls per day at $150 average value is leaving over $160,000 on the table annually. Most business owners underestimate this because missed calls are invisible — you never see the customer who hung up and called your competitor. Studies from various industries consistently show that 85% of callers who don't reach a live answer on the first try won't call back, and around 75% of people say they won't leave a voicemail at all. The customer simply moves on.

Industry matters a lot here. A dental office missing a new patient call might lose $2,000 or more in lifetime value. A law firm missing a personal injury inquiry could forfeit tens of thousands. Meanwhile, a retail shop missing a call about store hours loses almost nothing. The calculation really comes down to your average transaction size, how often customers return, and how competitive your local market is. In any market where callers have easy alternatives — which is most markets today — the cost of being unreachable is very real.
