How the calculator works

The maths is simple, and you can see every step under the result:

  1. Slow-answered leads = new leads per month × the share not answered within 5 minutes.
  2. Customers you’d normally win from those = slow-answered leads × your usual close rate.
  3. Revenue at risk = those customers × your average customer value.

It’s an estimate, not a promise. It assumes that leads who wait too long are lost to a faster competitor, which won’t be true for every single lead. To be cautious, use your normal close rate rather than an optimistic one, and use the value of a first sale rather than lifetime value.

Where to find your numbers

  • Leads per month: count form submissions, ad leads and calls from new numbers in your phone system or CRM.
  • Not answered within 5 minutes: check your missed-call report and the timestamps on form replies for one normal week. Many owners are surprised by this number.
  • Average customer value: your average first invoice, or average yearly revenue per customer if most customers come back.
  • Close rate: of the leads you actually speak to, how many become customers.

Frequently asked questions

It’s a practical line. People who reach out usually contact more than one business, and by the time several minutes have passed, many have already had a reply from someone else. If your business replies faster on average, move the slider down.

No. The calculation runs in your browser. Nothing you type is stored or sent.

Reply to every new lead within a minute or two, text back missed calls, and follow up with people who go quiet. That’s exactly what the AI Lead Response & Booking System does automatically.
