Frequently asked questions

How is the estimate calculated?

We multiply your missed calls per week by about 4.33 weeks per month to get monthly missed calls, then apply the close rate you enter to estimate how many would have become paying customers, then multiply by your average customer value. It's meant as a directional estimate, not an exact figure.

Where does the 20% default close rate come from?

It's a starting point you can adjust, not a claim about your specific business. Some industries convert missed-call leads at a much higher or lower rate — use whatever number reflects your real experience, or your CRM data if you track it.

Does this include calls handled by voicemail?

Only if you count a voicemail as a "miss." Many callers hang up rather than leave a message and call a competitor instead, so if that matches your experience, count those as missed calls too.
