TL;DR: Key Takeaway
Most business owners can't answer this question, which means they can't tell good marketing from bad. Here's how to calculate your real cost per lead, what a 'good' number looks like, and why it's the only metric that matters.
Ask a business owner what a customer is worth to them, and most can answer within a few seconds. Ask what it costs them to get one, and the room goes quiet. Marketing is one of the few expenses businesses run for years without knowing the unit cost.
That gap is why bad marketing survives. If you don't know what a lead costs, you can't tell whether $2,000 a month is a bargain or a waste. And you can't compare channels, agencies, or campaigns against each other. Cost per lead is the number that makes every other marketing decision possible.
Cost per lead is what you spent divided by how many leads it produced. Simple in theory. The complexity is in what counts as 'spent' and what counts as a 'lead.'
Be strict. A lead is a real inquiry from someone who could plausibly become a customer: a phone call, a form submission, a booking request, a DM asking about pricing. Likes, follows, and website visits are not leads. Spam form fills are not leads.
Example
$1,500 ad spend + $800 management fee + $200 amortized content = $2,500. It produced 25 real inquiries. Cost per lead: $100.
Cost per lead is the diagnostic. Cost per customer is the verdict. If 25 leads at $100 each produce five customers, your cost per customer is $500. Whether that's good depends entirely on what a customer is worth.
Cost per lead varies wildly across industries because job values vary wildly. A number that would bankrupt a pizza shop is a bargain for a roofer. Rough ranges we see for Connecticut local businesses on well-run Meta campaigns:
These are ranges, not targets. Your number depends on your area, your creative, your offer, and how fast you follow up. The trend over time matters more than any single month.
