What counts as a lead here?

A lead can be a call, form, message, quote request, or any other real inbound sales chance.

Why use three close rates?

Fast replies usually convert best, slow replies usually convert worse, and missed leads usually convert worst.

Can this work for service businesses?

Yes. It is especially useful for service businesses that depend on inbound demand.

What this means

Fast response looks weak

Your fast-response rate is below the range we use for general small business

With only 42.9% of leads getting a fast reply, you are likely losing about 16.6 sales a month compared with handling every lead quickly.

At an average value of $280, that is about $4,636 in monthly revenue leakage.

Calculator guide

How to use this missed call calculator

This calculator estimates how many sales and how much revenue can disappear when warm leads get a fast reply, a slow reply, or no reply at all.

Why missed leads hurt so much

Warm leads do not stay warm for long. If your response is slow, the customer often books somewhere else.

That means the business can feel quiet even while demand is already there.

How to read the result

If the lost revenue is high, the issue may be response speed, coverage gaps, or weak follow-up rules.

This is often easier to fix than trying to buy more leads.
