How the math works

Calls per week times percent missed gives missed calls per week. We multiply by 4.33 weeks to get a month, times your close rate to get lost deals, times your average customer value to get lost revenue. Every number above is yours, so the result is an honest estimate for your business, not an industry average.

This is an estimate based on the numbers you enter. A missed call is not always a lost customer, but every missed call is a chance you did not get to win.

Missed call text back sends an automatic text the second you miss a call, so the lead talks to you instead of the next result on Google.

Why missed calls quietly drain local businesses

A ringing phone is a buying signal. Someone wants what you sell, right now. When that call goes to voicemail, most people do not leave a message. They tap back to the search results and call the next business.

The loss is invisible because it never shows up as a complaint or a bad review. It is just revenue that never arrived. The calculator above makes that hidden number visible so you can decide if it is worth fixing.

The fix: missed call text back

Missed call text back watches your business line. The moment a call goes unanswered, it fires an automatic text to the caller, something like "Sorry we missed you, how can we help?" The caller replies by text, and the conversation keeps going.

This turns a dead end into a live lead. GoHighLevel includes missed call text back, along with the booking and follow-up that turn the text into a customer. Start the 30-day free trial and stop losing the calls you already paid to get.

Frequently asked questions

How does the missed call calculator work?

You enter four numbers: calls per week, the percent that go unanswered, your average customer value, and your close rate on answered calls. The tool multiplies them out to estimate the revenue you lose to missed calls each month and year. All the math runs live in your browser.

What percent of calls do businesses miss?

It varies a lot by business and time of day. The tool starts at 25 percent as a common example, but you should change it to match your own experience. After-hours calls, lunch rushes, and busy job sites push the number higher.

Is a missed call really a lost customer?

Not always, but a missed call is a chance you did not get to win. Many callers do not leave a voicemail. They simply call the next business in the search results. The calculator estimates the value of those lost chances using your own close rate.

How do I stop losing money to missed calls?

Missed call text back sends an automatic text the second you miss a call. The caller gets a friendly message, replies by text, and the conversation continues instead of ending. GoHighLevel includes this, and you can try it on the 30-day free trial.
