What are missed calls costing you?
An unanswered phone call is not a lost call — it is a lost customer, and only the share you would have closed actually costs you money. The arithmetic is: calls per month, times the proportion you miss, times the rate you close the ones you do answer, times what a customer is worth. A business taking 100 calls a week, missing a fifth of them, closing a third and worth $500 a customer is losing roughly $14,400 a month. Automatic text-back — an SMS sent the moment a call goes unanswered — is the usual fix, and it costs a subscription plus about $0.01 per message once carrier fees are counted. The calculator below runs your own numbers and tells you whether the recovery would exceed the software cost, or whether you would be better off answering the phone.
Your result
The arithmetic, written out
No black box. Four numbers and two multiplications:
- Calls a month = calls a week × 4.33
- Missed calls = that × your miss rate
- Lost customers = missed calls × the rate you close answered calls. This is the step most versions of this calculator skip, and skipping it inflates the number badly — a missed call from someone who was never going to buy costs you nothing.
- Lost revenue = lost customers × customer value
Recovery is then a fifth number you supply: what share of those you think a text would win back. There is no defensible published figure for this, so the calculator refuses to pick one for you.
Why calls go unanswered
In the businesses where this matters most — trades, clinics, salons, anything where the person who answers the phone is also doing the work — the pattern is consistent. Calls arrive while someone is on a roof, with a patient, or already on another line. Nobody is being careless. The phone is simply not the thing they are paid to hold.
Which is why "hire a receptionist" and "just answer it" are weaker answers than they sound. The call arrives at the exact moment attention is elsewhere.
What text-back actually does
The mechanism is unglamorous. A call comes in and goes unanswered. A workflow fires and sends an SMS from the same number: an apology and an offer to help. The caller replies by text, which they can do from the top of a ladder or a waiting room, and the conversation continues there.
The value is not the message. It is that the caller stops dialling the next business on their list. You have converted a lost call into a slow conversation rather than a fast one.
It is a small automation, not a product category. Several platforms include it, and the honest framing is that you are buying the platform, not the feature.
What it costs to run
Two layers. The subscription, and the messages.
On GoHighLevel the entry plan is $97 a month. The SMS itself is $0.00747 per segment, plus a carrier surcharge of roughly $0.0042 that most pricing pages leave out — so call it about a cent a message in practice.
At a few hundred missed calls a month the messaging is a rounding error and the subscription is the real decision. That is worth knowing before anyone sells you on per-message pricing as though it were the main cost.
When this is not worth automating
If the calculator shows recovered revenue below the subscription, do not buy software. Either your volume is too low, or your customer value is too low, or the honest fix is that someone should answer the phone during business hours.
The same applies if you only miss calls out of hours and your customers are happy to leave a voicemail. Automation earns its place when the volume genuinely exceeds what a person can catch — not as a way to avoid picking up.
One legal note worth taking seriously: automated messaging in the US falls under TCPA. Replying to someone who just called you is a different situation from texting a purchased list, and the second one gets people sued.
Common questions
What is missed-call text-back?
An automation that sends an SMS the moment a call goes unanswered — usually something like “Sorry we missed you, how can we help?” The caller replies by text and the conversation continues there instead of them phoning the next business on the list. It is a small piece of automation, not a product category, and several platforms include it.
How much does missed-call text-back cost to run?
Two costs. The platform subscription, which starts at $97 a month on GoHighLevel's entry plan, and the SMS itself at $0.00747 a segment plus carrier surcharges of roughly $0.0042 more. At a few hundred missed calls a month the messaging cost is a few dollars; the subscription is the real line item.
Is the recovery rate in this calculator a real statistic?
No, and that matters. It is an input with a starting value, not a measured figure. We have not run a controlled study and neither has anyone else publishing numbers on this. Treat any site quoting a precise recovery rate as an unsourced marketing claim until they show you the method.
Do I need software, or should I just answer the phone?
If the calculator shows recovered revenue below the cost of the subscription, answer the phone. Automation is worth buying when the volume is high enough that a human genuinely cannot catch every call — not as a substitute for someone picking up during business hours.
Will texting people back annoy them?
It can, if the message reads like a robot or arrives hours late. It works when it is immediate, plainly written, and a real person takes over the conversation. Automated follow-up also has to respect consent rules — in the US that means TCPA, and replying to an inbound call is a different situation from cold-texting a list.
If the numbers say yes
The platform is the cost, not the feature. Before committing, work out what it actually comes to at your volume — the subscription is only part of the bill, and metered usage is where the surprises live.
