For many service businesses, the phone is still the most important inbound channel. A caller ready to book doesn't usually leave a voicemail and wait — they move on to the next option. Every unanswered ring is a booking opportunity that rarely comes back.
This calculator is a directional tool. Enter your own numbers — missed calls per month, average job value, and your close rate — and it will show you what those unanswered calls may be costing you each month. Think of it as your estimate, not a benchmark.
The actual impact varies widely by industry, competition, and how persistent your callers are. What the calculator shows is a reasonable lower-bound scenario: if those calls had been answered with the same close rate you achieve today, what could the monthly revenue difference look like?
All numbers are yours — adjust each slider or type directly into the input fields.
BookedSmarter answers those calls from $149/month — so your business captures bookings around the clock, even when you're on a job or off the clock.

Three reasons the missed-call math compounds faster than most owners expect.
When someone needs a plumber, a salon appointment, or a tow, they're calling multiple businesses. For many service categories, the first business to answer wins the job — the rest of the calls go unanswered or to voicemail and simply don't get returned.
A single missed $350 job might feel manageable. But across a month — and then a year — even a modest miss rate adds up to a number that surprises most owners when they actually run it. The calculator above shows your number, not a generalized benchmark.
Calls that come in evenings, weekends, and holidays often represent your most motivated prospective customers. They have an urgent need. Without an always-on answering solution, those calls reliably go to voicemail — or to a competitor who does pick up.
Common questions about how the estimate works and what it means.
Your monthly estimate = Missed calls × Close rate × Average job value. For example: 40 missed calls × 40% close rate × $350 job value = $5,600/month. This is entirely based on the numbers you enter — there are no hidden industry averages or multipliers. It represents the bookings you likely could have won if those calls had been answered and converted at your normal close rate.
Most business phone systems and VoIP providers show missed-call logs in their dashboard or app. You can also check your mobile voicemail count as a rough proxy. If you're unsure, start with a conservative estimate — even a small number produces a meaningful monthly figure when multiplied by job value and close rate.
Good question. In reality, callers who go to voicemail sometimes do call back, and some may be lower intent. The calculator applies your stated close rate uniformly for simplicity. If you believe callers who would have reached voicemail are less likely to convert, you can lower the close rate slider to build that assumption in. The point is to get a directional sense of the opportunity — not a guaranteed forecast.
