How Many Leads Do You Actually Need?

We see owners spend months trying to get “more leads” without ever saying how many more. More than what? By when? If nobody has named the number, then nobody can tell whether the marketing is working, whether it is too little, or whether it is already more than the business can handle.

So let’s do what I do with a napkin. We start at the end, with the customers you want, and walk backward until we arrive at a lead number you can actually plan around.

Start with customers, not leads

A lead is someone who raised a hand. A customer is someone who paid. Those are two different things, and the gap between them is your close rate, which is simply the share of leads that end up buying.

Before you can work backward you need three answers. How many new customers do you want each month? What share of your leads become customers today? And how many of those leads are the wrong fit and never had a chance? If you have no history yet, that last question is why you keep a record from the very first inquiry. I go into that in Why You Need a CRM Before You Spend on Ads, because you cannot know your close rate if you never wrote down who called.

The formula is one line: leads needed = customers wanted ÷ close rate.

A worked example, labelled as an example

Say an HVAC company wants 6 new customers a month. Say, from the last few months of records, about 1 in 5 leads becomes a paying customer, a 20% close rate. These are made-up numbers for illustration. Yours will be different.

Six customers divided by 0.20 is 30 leads a month. The number is 30, not “as many as possible.”

Now look at where the leads are lost, because the close rate is really a chain. Say half of the 30 leads (15) turn into a quote or estimate, and 40% of those quotes (6) turn into a job. Fifteen times 0.40 is 6, so the chain agrees with the 20% figure. The useful part is that you can now see two levers. You can find more leads, or you can improve one link in the chain, like answering faster or following up on quotes that went quiet.

There are two ways to get there. Getting 30 leads by spending more is one way to reach the goal. Getting 6 customers from 24 leads by closing better is another, and it usually costs less. Which one is your business short of: leads, or follow-up?

Add a cushion, then check it against reality

There is a trap in the other direction too. Owners who see “30 leads” sometimes buy 30 leads from anywhere, and then wonder why the close rate falls. A lead from a friend’s recommendation and a lead from a broad ad are not the same animal. If your close rate is 20% on referrals and you add a channel that closes at 10%, the blend will drop, and your lead number has to rise to match. That is arithmetic, and it is better to see it coming.

Months are uneven. Some weeks the phone is quiet for reasons that have nothing to do with you. So plan for a little more than the bare number. In the example, you might aim for 33 or 35 leads to protect the 6 customers, and treat 30 as the floor rather than the target.

Then run the other check, the one owners skip. Can you serve 6 new customers a month? If the crew is already full, 30 leads a month may be a problem rather than a plan. I take that up later in this track, in Marketing When You Are Already Full. And once the marketing is running, How to Track Results shows how to see whether you are actually getting the 30.

This week

Write down how many new customers you want per month, one number. Count last month’s inquiries and how many became customers, and divide to get your close rate, even if it is rough. Then divide customers wanted by your close rate, write down the lead number, and add a small cushion, noting the floor beside it.

With records in hand this takes about an hour. If you have never tracked inquiries, expect a week or two of collecting before the close rate means anything. It costs nothing; a notebook or a spreadsheet is enough.
