Enter your trade, your missed-call volume, and your average job value below to see your estimated weekly and monthly revenue lost.

Why Missed Calls Cost More Than You Think

Here's the uncomfortable math: 78% of callers won't leave a voicemail when a call goes unanswered. They just hang up and call the next business on the list — often a competitor who happened to pick up first. Depending on the trade, a single missed call can represent $200 to $500 in lost revenue, and average job values vary widely by trade (a routine plumbing call looks very different from a full HVAC system replacement).

Calculating missed call ROI starts with a simple truth: you already paid for that lead. Whether it came from your local SEO rankings, Google Ads, or word of mouth, the marketing spend is sunk the moment the phone starts ringing. An unanswered call doesn't just cost you one job — it's revenue lost to missed calls that you already paid to generate, handed to whoever answers instead.

What Is a Missed-Call Text-Back System?

A missed-call text-back system automatically sends a text message to a caller the moment their call goes unanswered — so instead of silence, they get an immediate response letting them know they've been heard and someone will follow up shortly. It's a simple mechanic that recovers leads who would otherwise hang up and call the next business on the list.

Homefield SEO's AI Voice Agent includes missed-call text-back automation built in: if a call somehow slips through, the agent texts the caller back automatically so the lead doesn't go cold — on top of answering the vast majority of calls itself, 24/7.

Frequently Asked Questions

Multiply your missed calls per week by your average job value to get your weekly revenue lost, then multiply that by roughly 4.33 to estimate a monthly figure — that's exactly what the calculator above does automatically. The harder part is being honest about your real average job value and how many calls you're actually missing, which is usually more than owners think.
It's not a separate tool — it's shorthand some people use for a calculator like this one, which estimates the revenue impact of missed calls that a text-back system (like the one built into our AI Voice Agent) would otherwise recover. This calculator focuses on the revenue side; the text-back automation itself is what actually recovers those leads.
It depends entirely on your call volume and average job value, which is why we built a calculator instead of quoting one number. As a rough industry reference, a single missed call is commonly estimated at $200–500 in lost revenue for a home service business — multiply that by however many calls you're missing a week to see your real exposure.
It works for any home service trade. Select your trade from the dropdown and it pre-fills an industry-illustrative average job value — plumbing, HVAC, electrical, and roofing & exterior are built in, plus a general option for anything else. You can always override the number with your own real average job value.
