Above healthy range

Under $25K/yr in lost revenue is typical for businesses with live answering or a strong voicemail-callback process.

Where this number comes from

A caller who reaches voicemail is holding a list of other numbers, and the next one that answers usually gets the job. That is the whole mechanism: you are not competing on price at that moment, you are competing on picking up. This tool prices what that costs you instead of leaving a message.

How this calculation works

We multiply your weekly missed calls by your close rate to estimate jobs lost. Each lost job is then valued at your average ticket price, with a multiplier for repeat customers (the long tail of lifetime value most owners forget about). The default 30% repeat rate × 3x LTV multiplier comes from typical home-service industry benchmarks (HVAC, plumbing, cleaning). Your real numbers may be higher, especially for recurring services like pest control or maintenance.

Real scenarios

Solo HVAC operator

1 truck, $450 avg ticket, misses ~12 calls/week between job sites.

Loses ~$165,000/year in missed revenue when you add repeat-customer LTV. Even a $300/mo AI receptionist pays for itself 45x over.

Cleaning company with 4 crews

Recurring weekly + biweekly clients, $180 avg, 7 missed calls/week.

$85K+/year in missed revenue because cleaning has long LTV (60% repeat rate, 8x multiplier). One booked repeat client pays for AI for the year.

Plumbing shop, 3 techs

Emergency + scheduled work, $385 avg, calls at all hours.

Most missed calls happen after-hours and on weekends, exactly when emergency tickets are highest-value. 24/7 coverage is where the ROI is.

Frequently asked questions

Are these numbers realistic?

Yes. For a typical local service business doing $350 average tickets, missing 8 calls a week is around $5,800/month in lost revenue when you include the repeat customer LTV. Most owners are shocked the first time they see the math.

How do I actually stop losing calls?

Three options: (1) hire a virtual receptionist ($300-500/month per line), (2) use an AI receptionist that answers 24/7 ($0.25/minute, no contract), or (3) forward unanswered calls to your cell phone (works during business hours only). Smarfle includes the AI option built-in.

What if I miss a call but the customer leaves a voicemail?

Roughly 30-40% of voicemails turn into callbacks within 4 hours. The rest go to your competitor. Voicemail is better than nothing but is not a substitute for a live answer.

Why include repeat customer LTV?

A new pest control customer who chooses you for the first treatment will likely choose you for the next 3-5 treatments. Calculating only the first job's revenue understates the real cost of a missed call by 3-5x.
