Every agency will quote you a cost per lead in the first sales call. Almost none of them will show you where the number came from. I got tired of that gap between what people claim and what they can actually prove, so I ran the experiment on my own company first, with my own money, before I ever asked a client to trust a number I hadn't paid for myself.
Magnet Pro is my software company. It does Instagram growth automation, and across the life of the business it has processed more than $238,000 through its payment systems. Today it runs at a $148,000-a-year clip, and I touch it for about three hours a week. Most of that revenue comes from an organic engine, Reddit and SEO working together, running at $0 in core ad spend. That part compounds on its own. It does not need me watching it, and from 2024 to 2025 it grew 6.7x without me adding hours to the week.
The part that actually costs money
The organic engine is the floor. It's real, it's free to run, and it will carry a business a long way. But when I want to grow faster than "compounding on its own" allows, there's a paid layer on top of it, and paid acquisition is exactly where most agencies start rounding up, hedging, or quietly changing the subject. Ask three agencies what a qualified visit costs and you'll get three different vague answers, none of them backed by a real ad account they're willing to open in front of you.
So I decided to find the real number myself. Not model it in a spreadsheet. Not project it off somebody else's case study. Spend actual dollars, on my own product, and read the actual dashboard afterward, whatever it said.
$31,000, out of my own account
I put $31,000 of my own money into it. That wasn't a client's marketing budget I was managing on someone else's behalf. It was money that came out of my own account, spent to answer one question honestly: what does a qualified visit from a business owner actually cost, if nobody's rounding the number in their own favor.
The number that came out the other side was $5.05 a visit, pulled straight from the Meta Marketing API. Not estimated. Not "should land somewhere around." $5.05, for traffic that is specifically business owners, not general impressions dressed up as qualified leads to make a slide deck look better.
Why I paid for this instead of guessing
Guessing is cheap right up until somebody scales it. A firm that has never spent its own money finding a real cost-per-visit number is quietly asking you to be the one who finds out, on your budget, on your calendar, with your business as the test case. I didn't want to sell that version of the relationship. I wanted to be able to say, on the Zoom call, "here is what this actually costs," instead of "here is what it should cost if everything goes the way our deck says it will."
That's the difference between a projection and a receipt. A projection is a story about what a dollar might do. A receipt is what a dollar actually did, verified by the platform that took the money, not by the person hoping you don't ask to see the account.
What $5.05 actually bought
From 2024 to 2025, Magnet Pro grew 6.7x, with peak months running past $17,000. None of that happened because I got lucky with one clever ad. It happened because I had a real number to make decisions against instead of a feeling. When you know a visit costs $5.05, you know exactly how many visits a given budget buys, and you can size a test properly instead of flinching after three days of spend because the number "felt high."
That's the whole value of the $31,000. It wasn't really about Magnet Pro's growth curve, even though that curve is real and it's mine. It was about buying the ability to plan against a verified number instead of an optimistic one.
What this means if you run a business, not a marketing account
If nobody has ever shown you the actual dashboard behind your own numbers, ask for it. If a firm can't tell you what a qualified visit costs, verified, from a real ad account they'll open in front of you, they don't have the number either. They have a story about the number, and stories are free to tell and expensive to believe.
The whole reason I'm publishing this is so you can compare my $5.05, verified, against whatever number the next agency quotes you, unverified. You shouldn't have to take either one of our word for it. You should be able to ask for the receipt.
I still run Magnet Pro mostly hands-off, at that same low weekly time commitment, with the organic engine still carrying most of the weight at $0 core ad spend. The $31,000 I spent finding the paid number was never really about Magnet Pro at all. It was about being able to walk a client through the real math instead of a deck. That's the entire method, compressed into one number: $5.05.
