TL;DR: A missed call costs a service business the job that call would have become, and you can put a number on it with four figures from your own business: new customer contacts per month, the share that goes unanswered or gets a reply the next day, how often you close the ones you do answer, and your average ticket. Multiply them and you have what is at stake every month. This article runs that math on a made-up example, shows where missed contacts tend to pile up, and explains what an AI receptionist can and cannot do about it. If you searched for an AI receptionist Des Moines businesses can try before they buy, you are probably already feeling the leak. No industry averages and no invented percentages here: your numbers, or nothing.
What a missed call really costs
A missed call is not just a call nobody picked up. It is a job that never got quoted. The person who rang and reached nobody, or sent a message and heard back the next day, did not stop needing the work. They kept looking, and the business that answered first is the one they are likely to talk to next.
The cost is easy to ignore because nothing shows up on a statement when a job never happens. There is no invoice for the repair that went to someone else. Unless you count it, the loss stays invisible, and a loss you cannot see never gets fixed.
The formula: four numbers from your own business
You do not need a study or an industry average. You need four numbers that only you have:
- New contacts per month. Calls and messages from new customers. Leave out existing customers checking in.
- The share that goes unanswered. The percentage that gets no answer, or gets a reply the next day. Use your best honest guess, or the real number if you track it.
- Your close rate. Of the contacts you do answer, the percentage that end up buying.
- Your average ticket. What one job is worth to you, in dollars.
Multiply them: contacts per month x share unanswered x close rate x average ticket. The result is what is at stake each month if none of those contacts is recovered. If you think in weeks, count a normal week and multiply by four for a rough monthly figure.
Notice what this is not. It is not money you definitely lost, because nobody can know what would have happened. It is what the arithmetic says is on the table, using only numbers you chose.
A worked example, with made-up numbers
These figures are an example, not an average and not a claim about any real business. Swap in your own.
| Step | Example | Result |
|---|---|---|
| New contacts per month | 40 | 40 |
| Unanswered or answered next day | 25% | 10 contacts |
| Close rate on the ones you answer | 30% | 3 jobs |
| Average ticket | $400 | 3 x $400 = $1,200 a month |
| Over a year (12 months, no slow season) | $14,400 |
Now the part you control. Not everyone who did not hear back right away is still waiting by the time you reach them, even if the reply is instant. Our calculator starts the recoverable share at 50% on purpose, and you can move it up or down. At 50%, the example above gives about $600 a month and $7,200 a year. Keep the two figures separate in your head: $1,200 is what is at stake, $600 is what it is reasonable to expect back.
You can also break the number down without adding to it. If 6 of those 10 unanswered contacts arrived outside business hours, then 6 x 30% x $400 = $720 of the $1,200 is an after-hours problem. It is part of the same total, not extra money. Our free missed leads calculator does all of this with your numbers. It runs in your browser, sends nothing and saves nothing.
What the math leaves out
- It cannot see the customer's next move. A contact you missed might have gone to a competitor, come back later, or never bought. The calculation only does arithmetic on what you typed. Treat it as the start of a conversation, not a measurement.
- The recoverable share is your assumption. The more confident you are that people wait, the higher you set it. If you are unsure, leave it conservative.
- Seasons. The yearly figure assumes twelve ordinary months. If your business has a slow season, the number is optimistic for those months.
- Repeat customers. A recovered customer who comes back is worth more than the first job. That extra value is real, but it belongs in its own line, added on top of the estimate and not mixed into it.
Where missed contacts tend to pile up
Most owners can name the pattern once they look for it. These are the usual places the leak happens:
- After hours. The enquiry that arrives at 8pm on a Saturday gets answered Monday morning, and by then the customer may already have called someone else.
- The wrong language. A customer writes in Spanish, nobody on the team can answer that day, and the message quietly dies in the inbox.
- Whoever is free answers. Every customer hears a different version of your prices and your process.
- Ads that lead to a form nobody follows up the same day. You pay to bring the person in, then lose them at the door.
- The staffing math does not work. Hiring someone for evenings and weekends can cost more than the extra jobs would bring in.
If two or three of these sound familiar, the share of unanswered contacts in your formula is probably higher than you first guessed.
AI receptionist Des Moines: what ours does and does not do
Sinsajo Creators builds an AI receptionist Des Moines businesses can set up on their own website. It answers the chat on your site and your web enquiries at any hour, in English or Spanish, whichever the customer writes in. It asks the questions you would ask: what they need, when, where and the budget range. Then it offers your real open slots and books the appointment into your calendar. Every conversation is saved with the lead in the CRM, so you see what was said before you pick up the phone.
It also knows when to step aside. When a question needs a person, it says so and hands the conversation over instead of inventing an answer. An agent that bluffs about a price or a policy costs you more than a message left waiting.
What it is not: it is not a chatbot with canned answers, and in most cases it does not replace the people you already have. It covers the hours nobody is there and the first round of questions, so your team spends its time on the conversations that need a person. Which channels it covers is decided in the free consultation. The usual starting point is the chat on your website, because that is where most enquiries arrive.
We built it for ourselves before we sold it. Hanna, the agent on this site, answers our chat, qualifies our leads and books our calls, in English and in Spanish. You can open the chat and try to break it before you talk to anyone. If you want the full picture of the service, read about our AI receptionist Des Moines setup, including the questions people ask us most.
How it gets set up, and what it costs
- Free consultation. We go through the questions your customers actually ask, and the ones you need answered before an appointment is worth your time.
- We teach it your business. Your services, your rules, your tone, in both languages if you serve both markets.
- You test it first. You talk to it and try to trip it up, and we adjust until it sounds like you and not like a robot.
- It goes live, connected to your calendar. We keep tuning it with the real conversations it has.
The price depends on how many channels it covers and how deeply it has to know your business. We quote after a free consultation, and you see the number before any work starts.
Questions about missed calls and AI receptionists
Is the cost of a missed call the same as money I lost?
No. The formula shows what is at stake if none of the missed contacts is recovered. Some would have gone elsewhere or never bought anyway. That is why the recoverable share is a separate line that you set yourself.
Do I need to track every missed call to use the formula?
No. A best honest guess for the share that goes unanswered is enough to start. If you want a sharper number, count unanswered calls and messages for two normal weeks and use that.
Will an AI receptionist replace my front desk?
Usually not. It handles the hours nobody is there and the first questions, so the people you already have can focus on the conversations that need them.
Will it make things up about my business?
It answers from what you teach it. When it does not know something, it says so and offers to hand you the conversation. We tune that boundary on purpose, because an invented price does more damage than a message left waiting.
