What slow and missed replies cost your business each year
A free calculator. Put in five numbers from your own business and see the clients and revenue lost to calls no one returns and forms no one answers in time. No email. The math is shown in full.
Estimated loss each year
Estimated revenue lost per year: $45,000. Estimated clients lost per year: 18.
Here's the math
- 40 inquiries a month × 12
- 480 a year
- × 25% with no reply or a slow reply
- 120 inquiries
- × 50% you'd win back with a fast reply
- 60 inquiries
- × 30% close rate
- 18 clients
- × $2,500 average value
- $45,000 a year

How to estimate each number honestly
The result is only as good as what goes in. Use counts where you have them and careful guesses where you don't.
- New inquiries per month
- Count every new customer who reached out in a normal month: calls, website forms, texts, emails and social messages. Check your call log, your inbox and your form entries. Leave out existing customers, sales pitches and spam.
- Average value of a won job or client
- Use what a new customer spends on the first job. If most customers come back, you can use what they spend in a year instead. Just say which one you used when you quote the result.
- Close rate
- Of the inquiries you do answer, how many hire you? If 10 people ask for a quote and 3 say yes, your close rate is 30%. Use your last three months if you track it.
- No reply or a slow reply
- This is the hardest one to know, and that is the point. Count missed calls with no callback, forms answered the next day, and messages on accounts no one checks. If you cannot tell, send an inquiry to your own business after hours and time the reply.
- How many you'd win back
- Not every missed customer was going to hire anyone. Some were only comparing prices. Pick a share you could defend to a skeptic. If you are unsure, start low. A careful guess makes the result easier to trust.
How the number is worked out
Clients lost per year = inquiries per month × 12 × share with no reply or a slow reply × share you'd win back with a fast reply × close rate.
Revenue lost per year = clients lost per year × average value of a won job or client.
With the example numbers: 40 × 12 × 25% × 50% × 30% = 18 clients, and 18 × $2,500 = $45,000 a year. Nothing else is added, and no outside figures are used.
What to do with the number
- 1Compare the yearly figure with what you spend to get inquiries. If you lose more than you spend on ads, the leak comes before the ads.
- 2Find where it happens. Calls after hours, a form that lands in an inbox no one watches, and texts that wait until Monday are the usual places to look.
- 3Fix one thing first. A callback rule, an instant text reply, or one named person who owns new inquiries.
- 4Run the numbers again in a month with what you measured.

Common questions
Enter your monthly inquiries, the share that get no reply or a slow one, how many of those you'd win back, your close rate and your average job value. The calculator multiplies them and shows the yearly figure, with each step written out.
It is as accurate as the numbers you enter. It does plain multiplication, shown under the result, and it cannot see your phone or inbox. To know the real figures, you have to test your own replies.
Any reply that arrives after the customer has moved on. For some businesses that is minutes. For others it is a day. If you are not sure, contact your own business the way a customer would and time it.
No. The calculator runs in your browser. Nothing you enter is sent or saved.
