Most founders I meet can quote their contribution margin to the decimal. Ask them how much revenue it takes to cover a month of overhead and you get a pause. Contribution margin tells you the product works. It tells you nothing about whether the business does, and those are two different questions that founders collapse into one all the time.
I sat down with Abby June Richards, a fractional CFO who builds these numbers for growth-stage consumer brands, to talk about the metric almost nobody gets right: the actual revenue and unit volume a brand needs to break even.
She told me about a founder who brought her a new SKU, proud of it, because the per-unit margin beat everything else in the line. However, the product was also small with maybe a dollar of profit a unit. The brand’s overhead ran around $20k/mo, so breaking even on that one SKU meant selling 20k units every month just to stand in place. Then they did the part that grounds the analysis. They divided that by the stores the brand planned to be in, then by the weeks in a month, and landed on a velocity per store per week. Abby's phrasing - “the constraints become visible”. You stop asking whether the margin is good and start asking whether the volume is even possible.
Break-even tells you whether the business makes sense
Healthy unit economics are worth having, but they can hide a structure that doesn't add up. Abby has a client, a legacy business, carrying very high overhead. Even with very high margins, the unit volume they needed to clear that overhead was enormous. The break-even math was what surfaced it. Either the structure makes sense at the revenue you actually have, or it doesn't, and the only way you find out is by putting the fixed costs and the margin in the same equation and seeing how many units fall out.
This is also why Abby keeps overhead as lean as she can at every stage. She frames her job as working backward from how much money the brand will make and how much overhead that can support. Founders tend to run it forward, especially early: what do I need to get this off the ground, what does it cost me every month. Both are reasonable, but the forward version can commit you to carrying weight the revenue can't hold yet.
The payoff she pointed to is that once you break even, you get to be what she calls profitability optional. You can still choose to pour money into a launch or a new channel, but you no longer have to raise to survive, and you become eligible for kinds of debt that were closed to you while you were burning cash. It’s rare to get there until you break even, so the number isn't academic. It's the line between raising because you want to and raising because you're out of runway.
The many fixed costs you forget to budget for
The formula itself is plain.
Break-Even Net Revenue = Monthly Fixed Cost / Contribution Margin Percentage. Then, you can divide by net AOV in DTC or your case price net of trade spend to determine the volume. The arithmetic isn't the hard part. Getting the fixed-cost bucket honest is.
Rent is the one Abby flags first, and her advice is blunt: wait to have rent as long as you can. She's had founders walk in convinced they needed to drop their office, and she agreed on the spot, because the office was holding back profitability and the brand had no team and no real reason to sit anywhere. They'd signed the lease because having a business felt like it was supposed to come with an office. Her rule for that whole category is to question everything, since plenty of what founders assume they're supposed to do, other founders simply aren't doing.
A few line items tend to be missing entirely. Founder salary belongs in the long-term projections even during the stretch when there's no profit to actually pay it, because a plan that only works while you work for free isn't really a plan. Marketing is the other blind spot. You can sell a product into an account, but something has to pull it back off the shelf, and that sell-through money rarely makes it into the early model. Payroll is the one founders talk themselves out of the longest. You can run lean for a while, but four chains and a national footprint don't staff themselves with one exhausted person.
Then there's the category Abby calls fixed but not actually fixed. Insurance is her example. It sits in the fixed bucket, and it also grows right alongside the business, so the number you penciled in a year ago is wrong now. The discipline is sizing those as you scale instead of treating one old figure as permanent.

Overhead climbs, and it doesn't climb back down
The uncomfortable property of fixed costs is that they're sticky in one direction. Hiring brings payroll, and payroll brings benefits and the tax burden that rides on every head. A software rollout costs more than the quote suggested. Move into a warehouse and you inherit storage and minimums. All of it climbs as you grow, and almost none of it climbs back down on its own.
So Abby watches fixed costs as a percentage of revenue over time, not as fixed dollar amounts. If revenue slips, that ratio is the early warning, and it forces a question most brands never plan for: when things get lean, what comes out? Very few founders have a plan to weather a down stretch, which is strange, because it's one of the more important plans to have.
She'll push on the sacred stuff when she has to. A brand that runs its own warehouse and its own fulfillment is proud of that, and reasonably so, but Abby's question is whether that setup was built for the company you are today or the one you were hoping to be. If you won't be that larger company three months from now, moving to a more variable structure, a 3PL for the moment, takes the burden off the books until the volume earns it back.
One number across every channel will mislead you
A single blended break-even assumes your channel mix stays put. It won't. The moment you expect DTC to grow faster than wholesale, or a new retail account to shift the balance, the blended number drifts away from reality, and Abby's move is to re-run it at the mix you actually expect. The direction of the surprise can cut in your favor, too. If you're heading toward a DTC-heavy mix where the margins are richer, the revenue you need to break even might be lower than the blended figure implied.
Run it monthly, through more than one lens
Abby runs break-even monthly, because it's built off the financials and that's the finance rhythm. Her team shows it as a simple stacked bar: overhead on one side bucketed by type, contribution profit on the other bucketed by channel. If the bars match, you broke even. If contribution profit is taller, you made money that month, and if it's shorter, you didn't. One glance tells you where the money came from and where it went.
She doesn't stop at a single company-wide number either. There's break-even revenue for the business, break-even CAC in DTC, break-even CAC on Amazon, each one a different lens on the same path to profitability. Looking through several at once is how you keep the whole thing pointed in the right direction instead of trusting one figure to carry more than it can.
The best founders I know don't treat break-even as a line they cross once. They re-run it on any SKU, in any channel, whenever something big changes, and that habit is what catches the impossible math while it's still cheap to fix. Run the number before you fall in love with the margin. The volume tells you the truth the margin was hiding.
