    How the calculation works

    The calculator multiplies three things you know about your own business: how many calls you miss in a typical week, what share of those callers would normally become customers, and what a customer is worth to you. It then converts the weekly figure to a monthly and yearly one (52 weeks a year, divided by 12 for months).

    Worked example: a business that misses 10 calls a week, would normally book 25% of callers, and earns $300 per customer has about $3,250 a month, or $39,000 a year, at risk from calls nobody answers.

    The result is a size-of-the-problem estimate. Not every missed caller is lost for good, and some would never have booked. But most callers who reach voicemail don't leave a message; they call the next business on the list. If your numbers are honest, the figure is a fair picture of what slow or missed responses cost you.

    How to stop losing revenue to missed calls

    • Text back every missed call automatically. An SMS within seconds (“Sorry we missed you, how can we help?”) keeps the conversation with you instead of a competitor.
    • Offer a booking link in that first message. Many callers would rather pick a time than wait for a call back.
    • Put every call, text and message in one inbox. So whoever is free can reply, and nothing depends on one person's phone.
    • Follow up more than once. If they don't reply, a second and third message at sensible intervals recovers more enquiries.
    • Measure it. Track missed calls, replies and bookings so you can see the number in this calculator shrink.

    FAQ

    Missed-call questions

    How do I work out the cost of missed calls?

    Multiply the missed calls you get each week by the share that would have become customers, then by the average value of a customer. Multiply by 52 and divide by 12 for a monthly figure.

    Why do missed calls cost so much?

    Most callers who reach voicemail don't leave a message. They try the next business on the list, so the enquiry, and the revenue, goes to whoever answers first.

    How does missed-call text-back work?

    When a call goes unanswered, the system automatically sends the caller a text within seconds, such as “Sorry we missed you, how can we help?”. The conversation continues by SMS and lands in your inbox, so the lead stays with you.
