No email needed

Your calls

Calls you get in a week

Count calls to your main number. Your phone provider call log gives the real figure.

Share of calls you miss Assumption

Calls nobody picks up, including calls while you are on a job, at lunch or after hours. Replace this with a figure from your call log.

Share of missed callers who never ring back Assumption

The callers who try someone else instead. Voicemail left, then no reply, counts here.

Your jobs

Share of enquiries that become a paid job Assumption

Look at the last 20 enquiries you answered and count how many turned into work.

Average value of a job

Revenue before your own costs.

Profit margin on a job (optional)

Leave blank to see revenue only. Add it to see profit as well.

If an AI receptionist answered those calls

Share of missed calls it answers properly Assumption

Answers, captures the details and books or passes on the job. Test any receptionist on real calls before you rely on this figure.

Monthly cost of the AI receptionist Assumption

An example figure only. Replace it with a real quote from any provider, including us.

Business name for your script (optional)

When you press the button your answers go to our server, which checks the sums and saves a private link to your report. You do not need to give an email address.

How we work this out

Missed calls a month = calls a week × 4.33 × share missed. The 4.33 is 52 weeks divided by 12 months.

Lost jobs a month = missed calls × share who never ring back × share of enquiries that become a job.

Monthly loss = lost jobs × average job value. The yearly loss is that figure × 12.

Recovered a month = monthly loss × share an AI receptionist answers properly. The cautious case halves that share.

Cost cover = monthly cost ÷ recovered revenue. That is the part of a month of recovered work needed to pay for the receptionist. Times 30.4 days it gives a number of days.

The result is revenue, not profit, unless you add a margin. Every percentage above is an assumption until you replace it with your own data.

Example: 60 calls a week, 25% missed, 50% never ring back, 30% become a job and £250 a job gives about £2,436 a month in lost work.

How does the calculator work?

You answer five questions, and it multiplies them through. Nothing is sent anywhere until you ask for the report.

1
How many calls do you get in a week?
2
What share do you miss, as a percentage?
3
Of the callers you miss, what share never ring back?
4
Of the enquiries you do answer, what share turn into paid jobs?
5
What is a typical job worth, in pounds?

Then it shows your monthly loss, and what it would take for an AI receptionist to pay for itself.

What are the assumptions behind the number?

The method is simple and we show it under every result:

Missed calls a month = calls a week × 4.33 × share missed.

Monthly loss = missed calls a month × share who never ring back × share who become jobs × average job value.

We use 4.33 because that is the average number of weeks in a month. The result is an estimate from your own numbers. It is only as good as they are.

Here is an example with made up inputs. A firm takes 60 calls a week and misses 25%. Half of those callers never ring back, and 30% of enquiries become jobs worth £250 each. The loss is about £2,436 a month. These figures are an illustration, not a typical result.

Payback uses the monthly cost you enter for an AI receptionist, divided by the revenue it could win back. We assume it answers the calls you miss. If you only miss calls at certain times, use a lower share.

What do I get to keep?

You get a saved report with your inputs, your result and the method. You also get a short missed call script your team can use today. You can read it on screen, or ask for it by email.

Common questions

How accurate is it?

It is as accurate as your inputs. If you are unsure of a number, try a low and a high guess and compare.

Do I need to give my email?

No. You see the result straight away. Email is optional and only needed if you want the report sent to you.

What counts as a missed call?

Any call that goes to voicemail, rings out, or gets an engaged tone. Count calls you could not take, even if the caller left a message.

What does an AI receptionist do about it?

It answers when you cannot, takes the details, books into your diary and passes urgent calls on. Read about the AI Receptionist.

Does it work for my sector?

It suits any business that wins work by phone, such as trades, estate agents and dental practices.
