Missed Call Calculator: what are missed calls really costing your UK business?
Quick answer: the cost of missed calls = calls per week × missed-call rate × close rate × average customer value × 52. A UK business with 30 calls a week, 20% missed, a 40% close rate and a £250 job loses up to £31,200 a year. Use the missed call calculator below with your own numbers.

Your numbers
Pick your trade for starter numbers, then replace them with your own. Estimates only.
Not sure? Count one week
Check your phone log or call app. Your own count beats any national statistic.
Starter numbers are examples, not UK benchmarks. This tool assumes a missed caller is lost, so the headline is a ceiling. Below it we show the cost if half of them ring back.

How to calculate the cost of missed calls
This missed call calculator uses four numbers you already know, or can count in a week. Nothing is guessed for you.
Calls per week × missed % × close rate × customer value × 52 weeks = yearly cost
Example: 30 calls a week with 20% missed is 6 missed calls. A 40% close rate means about 2.4 customers lost each week. At £250 each that is £600 a week, or £31,200 a year. If half of those callers ring back, the loss is still around £15,600.
What is a good missed call rate for a UK business?
There is no official UK benchmark for missed call rate. A widely used rule of thumb from UK marketing sources is that anything above roughly 15% during opening hours should be fixed before you spend more on marketing. Treat it as a guide and measure your own week.
| Missed in opening hours | What it usually means |
|---|---|
| Under 10% | Healthy. Keep checking your log weekly. |
| 10% to 15% | Watch it. Lunch hours and busy mornings are the usual leaks. |
| Above 15% | Fix this first. New marketing will leak money until calls are answered. |
3 ways to win back missed calls
Cover the busy hours
Check when calls go unanswered. Lunch hours and first thing in the morning are common. Even one person covering the phone then can close the gap.
Set up missed call text back
When you miss a call, send an automatic text such as “Sorry we missed you, how can we help?” with a booking link. Missed call text back keeps the enquiry alive while you are busy.
Review the call log weekly
Spend ten minutes every Monday on last week’s missed calls. Call back within two hours. What gets counted gets fixed.
The 7-day missed call test
Want a number you can trust? Do this before you change anything.
- Export or note every inbound call for 7 days. Your phone provider, call app or handset log all work.
- Mark each call as answered or missed. Only count calls during opening hours.
- Divide missed calls by total calls to get your missed call percentage.
- Type it into the calculator above and write down the result.
- Apply the fixes, repeat the test next week and compare.
Why answering local business phone calls matters more now
Many local customers now find a business through Google Maps, your Google Business Profile or an AI answer from ChatGPT, Gemini or Perplexity, then call straight away. Getting found is only half the job. If nobody answers, the customer rings the next result. That is why local SEO and call handling work best together, and why I also help UK businesses show up in AI search and answer engines.
Missed call calculator FAQs
How do I calculate the cost of missed calls?
Multiply the number of calls you get per week by your missed-call percentage, then by your close rate, then by the average value of a customer, then by 52. This missed call calculator does it for you and shows the loss per week, per month and per year.
How much do missed calls cost a small business in the UK?
It depends on how many calls you get, how many you miss, your close rate and your average customer value. A UK business with 30 calls a week, 20% missed, a 40% close rate and a £250 job loses up to £31,200 a year. Enter your own numbers in the calculator for your figure.
What is a normal missed call rate for a local business?
There is no official UK figure. A common rule of thumb is that more than about 15% of calls missed during opening hours is worth fixing before you spend more on marketing. Count your own week to find your real number.
Is it true that 62% of calls to small businesses go unanswered?
That figure is repeated often online, but it traces back to a 2016 study of just 85 businesses, so I do not use it. This calculator uses your own missed-call count instead, which is more accurate for your business.
Will missed callers ring back?
Some will, but many ring the next business instead and few leave a voicemail. Because it varies, the calculator shows the full cost as a ceiling and also shows what you lose if half of them ring back.
How can I stop losing customers to missed calls?
Start with three steps: cover the busiest hours, set up an automatic missed call text back, and review your call log every week. Call back missed numbers within two hours where you can.
Do I need to sign up or pay to use the calculator?
No. It is free, needs no email address, and your numbers stay in your browser. If you want help turning the result into more calls, you can request a free audit.
Why I built this missed call calculator
I’m Nurul Nahid, an SEO and AI search consultant helping UK local businesses get more calls and bookings from Google Maps, Google search and AI answers like ChatGPT, Gemini and Perplexity.
When I work with UK business owners, I keep seeing the same thing. The phone rings, calls come in from Google, and the business feels busy. But nobody has counted how many of those calls go unanswered, so nobody knows what the missed calls cost. The loss is invisible, so it never gets fixed.
So I built this free missed call calculator to turn that invisible loss into one number you can act on. Use your own calls, your own close rate and your own customer value, and see the cost of missed calls in pounds. If the number is bigger than you expected, fix it first, before you spend more on SEO or ads.
I have 7+ years of experience in local SEO, Google Business Profile optimisation, e-commerce SEO and AI search (GEO and AEO). See my case studies, or read about my SEO work for Harlow businesses.
Found a big number? Let's fix the leak.
I will look at your Google profile, your website and how customers reach you, then show you where calls are being lost. It is free and in plain English.
