Quick question for you.

If I asked you to map out the exact path every dollar takes in your business, from the moment you invest it into acquiring customers and paying overhead, all the way through to actual profit, could you do it?

Not a vague description, but the actual journey. Every step, every place money leaks, every place it multiplies efficiently. The exact sequence that turns revenue into cash you can keep.

Most founders can’t answer that. And yet they’re running businesses, making scaling decisions, hiring agencies, testing channels, all of it, without being able to see the full picture.

That’s not a knock on you or them. It’s just the reality I see after being behind the scenes of dozens of seven and eight-figure physical product businesses over the last 20 years.

That’s why I want to walk you through the five levers that make up what I call a profit model. When you understand these, the whole game changes. Not because you have better marketing, but because you finally understand what you’re working with.

What a Profit Model Actually Is

If you strip business down to its core essence, it’s essentially this: how much do you invest, how long does it take to break even on that investment, and how much do you make after that?

The faster that cycle happens and the more you make on the back end of it, the more profitable and scalable your business becomes. Simple concept, yet most people never sit down and measure it.

That said, a profit model is everything that happens in between the dollar going out and the customer being fully maximized. All the steps. All the levers. All the places where you’re either building profit or draining it.

There are five core components to it. And the reason I’m specific about five is because every single thing you can do in your business, and there are a thousand things, ultimately moves through one of these five levers. When you understand that, prioritization gets a lot easier.

Lever 1: Contribution Margin

Contribution margin (CM) is simply how much you keep from each sale after all your variable costs. Not gross margin. Not what Shopify shows you. The real number, after cost of goods sold (COGS), shipping, fulfillment, returns, payment processing, and anything else that scales up or down with your unit volume.

The reason I emphasize this is because most founders think they know this number and don’t. I had an eight-figure client tell me their flagship program had a 40% contribution margin. So I dug in and added up everything, such as payment processing, refunds, chargebacks, sales commissions, platform fees, event costs, coaches, and everything that went into fulfilling that product.

The real number wasn’t 40%. Or 30%. Or even 20%…

It was 14%.

That program was their golden goose. Everything in the business was designed to push people into it. And when we ran the actual math, they were barely keeping anything.

This is not unusual. It’s the most common thing I find.

Here’s why it matters so much beyond the obvious: for most of the calculations I run, a 10% improvement in contribution margin, say, going from 50% to 55%, typically produces somewhere in the range of a 40 to 60% increase in net profit. That ratio is what makes this lever so powerful. Small improvements here create massive downstream impact on everything else.

And it’s also why discounting is so dangerous. If your contribution margin is 50% and you run a 25% off promotion, you’ve just cut your profit per unit in half. You’d need two to four times the volume just to break even on that promo. Yet unfortunately, most people don’t do that math before they run the sale.

Lever 2: Acquisition Economics

This is the lever most people are most familiar with because marketing is sexy. I was a direct response copywriter for the first decade of my career. I love this stuff. It’s fun. I get it.

But it’s just ONE out of FIVE levers. And it’s already the most competed-over, most optimized lever in most businesses. Which means the returns from improvement here are often lower than people expect.

There are two sides to acquisition economics. The first is conversion efficiency, how well you’re turning prospects into customers. The second is economic efficiency, specifically how much contribution margin you’re generating per order.

The real number you need to know here is your Allowable Customer Acquisition Cost (ACAC). Not your target customer acquisition cost (CAC). Not some industry benchmark. The actual maximum you can spend to acquire a customer while remaining profitable, calculated from your real contribution margin, your lifetime value, and your overhead per customer.

Most founders are either overspending because they’re not factoring in true variable costs, or underspending because their ACAC ceiling is actually higher than they think and they’re leaving volume on the table. Both are expensive mistakes, and you can’t know which one you’re making without the math.

Lever 3: Lifetime Value

Most people know what lifetime value (LTV) is. And most people are calculating it completely wrong.

The common approach is to take total revenue and divide by total customers. Simple, and also almost useless for making real decisions.

What you need is LTV by timeframe and by cohort. What did customers who first purchased in January 2024 generate by April? By July? By January 2025? And how does that differ by traffic channel?

That distinction matters a ton for acquisition decisions. If your Facebook customers have a 12-month LTV of $280 but your Google customers have a 12-month LTV of $490, you can afford to pay a hell of a lot more to acquire from Google. But that’s a decision you can only make with the right data.

Once again, you have to adjust LTV for contribution margin. Raw revenue LTV tells you how much customers spend. Contribution margin-adjusted LTV tells you how much of that you keep. Those are very different numbers, and you need the second one to make real decisions.

I generally like to look at a one-year LTV as the primary benchmark for most businesses. Everything after that is a bonus.

Lever 4: Operational Efficiency

This one is massively overlooked. Probably the most overlooked of the five.

The core metric here is your overhead-to-revenue ratio. How much output are you generating per dollar of fixed cost? If you have $1M in revenue and $100K in fixed overhead, you’re at a 10:1 ratio. If you have $1M in revenue and $300K in overhead, you’re at 3:1. That’s a $200K difference in profit from the same revenue.

What kills a lot of growing brands is that revenue and expenses scale in lockstep. It’s very common to see overhead go up just as quickly, or almost as quickly, as revenue. That leaves you in a situation where revenue is increasing, but profit is either flattening or barely creeping up.

Not a good situation.

But there’s a second side to this that matters just as much, even if you can’t put a number on it right away. The stress side. I’ve worked with so many founders who are completely buried in their day-to-day. Constant fires, constant questions from the team, can’t take a vacation without their stomach dropping. That’s an operational efficiency problem too. And luckily, it’s very fixable!

Here’s a test I use…

Could you step away from the business for a full week right now without it falling apart?

If the answer is no, that’s the problem telling you exactly where to look.

The answer here is very simple: Get the right people, in the right seats, working on the right priorities, efficiently.

Do that and you’ll watch your profit AND happiness levels skyrocket.

Lever 5: Capital Return Velocity

Capital Return Velocity (CRV) is how long it takes for cash you invest into the business, inventory, overhead, acquisition, to come back as usable, deployable profit.

It’s a metric that almost nobody tracks, and it’s probably the single biggest cause of cash crises in physical product businesses.

I created this term because there was no existing accounting concept that captured the full picture. For example, cash conversion cycle only gives you inventory-specific timelines. Payback period only tells you how long it takes to cover your acquisition costs.

But neither of them connect inventory timing, acquisition cost, contribution margin, and overhead into one number that tells you how fast your capital cycles.

Capital return velocity does.

This metric is typically painful when people calculate it for the first time, because most people think they’re breaking even within 30-60 days, yet in reality it’s closer to 6+ months.

Think about what it means to make every growth decision assuming a 30-day payback when your real payback is 6+ months. Every channel test, every inventory buy, every scaling push, all of it built on math that’s not even remotely accurate. That’s the kind of thing that creates a cash crisis right when the business looks like it’s growing.

The good news is there are a lot of things you can do to improve CRV. Better payment terms with suppliers. Faster inventory turns. Tighter contribution margins. A stronger post-purchase sequence that pulls forward LTV. And many others.

Even better is that fact that improving any of the other four levers automatically improves this one too, because you’re getting more cash back per customer, faster.

Why Five Levers Instead of Just Marketing

Here’s the math I think about a lot.

If you focus entirely on acquisition economics and improve it 10%, you can generally expect somewhere in the range of a 30 to 50% improvement in profit. That’s great. Anyone would take that.

But if you improve all five levers by that same 10%, the result is typically four to six times better than focusing on acquisition alone.

That’s why I teach this framework. Not because marketing doesn’t matter (it absolutely does, and I love it), but because the founders who win long-term are the ones treating their business as one connected system instead of just a marketing operation.

Where to Start

If you’re running a physical product brand and this framework is new to you, start by getting your real numbers. Not estimates. The actual numbers with everything accounted for.

Get your real contribution margin first. Then look at your capital return velocity. How long does it actually take your business to break even on a customer acquisition, after everything? Those two numbers alone will show you where your biggest constraint is faster than anything else I know.

Once you know the constraint, you know the priority. And once you know the priority, everything else gets a lot simpler.
