Prospective calls
Total monthly calls multiplied by the percentage that are potential new customers. Existing-job updates, vendors, spam, and other calls should not be counted as new opportunities.

How the missed-call estimate is built
The calculator narrows your total call volume at each step so repeat customers, non-sales calls, and leads that would not close are not all treated as lost jobs.
Potential customers
Missed prospective calls multiplied by the close rate you normally see when a qualified lead is answered. This is an estimate, so use language such as “potential” when sharing it.
Revenue opportunity
Estimated customers not won multiplied by average job value. The annual view multiplies a typical month by twelve; the optional lifetime view adds only the repeat-value multiplier you choose.
Turn call assumptions into a useful action plan
Separate new-business calls from every other ring
A busy phone line includes current customers, suppliers, staff, robocalls, and scheduling questions. Estimate how many calls are truly from potential new customers before assigning a job value. Call tracking or a simple one-month tally can make this percentage much more reliable.
Use the close rate for answered, qualified leads
The close rate should reflect what happens when a real prospective customer reaches the business. Divide customers won by qualified new-customer calls answered over the same period. If the data is uncertain, start conservatively and compare the result with a lower and higher rate.
Average job value should match the call mix
An HVAC company gets a different mix of calls than a recurring cleaning service. Use an average that matches the calls you actually get, not just the biggest jobs. Keep the lifetime multiplier at one unless your own records show repeat business.
Measure response improvements in practical steps
Reducing missed calls may involve scheduling coverage around peaks, improving call forwarding, adding text-back options, making online booking easier, or using an answering service. Compare a realistic current missed-call rate with 10% and 5%, then track whether the actual rate changes after improving coverage.
Missed call calculator FAQs
Does every missed call count as lost revenue?
No. The calculator narrows total calls to likely new-customer calls, then applies your missed-call rate and close rate. The result is an estimate of potential opportunity, not a claim that every missed call would have become a sale.
How should I estimate my close rate?
Use the share of qualified, answered new-customer calls that normally become paying customers. If you do not track this yet, start with a conservative estimate, review a month of calls, and compare several scenarios.
What counts as a new-customer call?
A new-customer call is an inquiry from someone who may purchase a service, rather than a current customer calling about an existing job, a supplier, an employee, or spam.
What can a service business do when the team cannot answer?
Useful options include a clear voicemail and callback process, call forwarding, after-hours coverage, online booking, web chat, text messaging, and an answering service that can qualify and route calls.
