The DTC Profitability Calculator builds your full profit and loss from revenue down to EBITDA, then benchmarks every layer against real DTC data so you can see exactly where the money goes.
- Healthy is 10 percent EBITDA or better. The DTC median sits near 5 percent: roughly 4 percent for seven-figure brands and 7 percent for eight-figure brands.
- Negative EBITDA means you are paying to trade. The calculator finds the leaking layer before you scale spend on top of it.
- Gross margin is not profit. Fulfilment, returns, marketing, and overhead each take a bite, and most brands cannot say which bite is the problem.
- Sixty seconds, no signup, and no spreadsheet upload to see your number.
Gross margin is not profit, and the gap between them is where most DTC brands quietly lose. The DTC Profitability Calculator builds your full P&L from revenue down to EBITDA, layer by layer, then benchmarks the result against real DTC data. Healthy is 10 percent EBITDA or better. The median is closer to 5 percent. If you are below it, the tool shows you which layer is doing the damage. It takes about sixty seconds and asks for nothing to show your number.
I built it because the most dangerous number in DTC is a healthy gross margin attached to a sick business. A founder sees 65 percent at the top and assumes the brand is fine, while fulfilment, returns, ad spend, and overhead are quietly turning that 65 into a negative bottom line. You cannot fix a leak you cannot locate, and a single blended margin number hides which pipe is leaking.
A good gross margin
can still lose money.
Run the brands I have run and you learn this the hard way. At WIN Brands Group we operated a portfolio, and the brands that looked healthiest on a gross-margin line were not always the ones that printed cash. Profit lives at the bottom of a stack of subtractions, and any one of them, handled badly, can swallow the whole margin. The fix is never "improve profitability" in the abstract. It is "fulfilment is eating eight points more than it should," which is a specific, solvable problem.
So I built the calculator to do the one thing a dashboard rarely does: stack the layers in order and show you the number at each line, against what good looks like. Not to flatter you with a single figure, but to point at the layer that is costing you the most.
Revenue down
to what is left.
The calculator walks the same path your money does. Start with revenue. Take out cost of goods for gross profit. Then take out the variable costs of actually delivering and selling: fulfilment and shipping, the cost of returns, payment fees, and the marketing it took to win the order. Then take out fixed overhead. What survives is EBITDA, the cash the operation really produces.
| Layer | What it takes out, and where it hides |
|---|---|
Cost of goods | Landed product cost. Gives gross margin, the number most brands stop at. |
Fulfilment + shipping | Pick, pack, freight, and the subsidy on free shipping. Climbs quietly with AOV and weight. |
Returns | Reverse logistics and lost resale value. Rarely a line on the P&L, which is the problem. |
Marketing | Blended acquisition. The layer most likely to turn a healthy margin negative. |
Overhead | Team, software, rent, the fixed base. It looks small until growth stalls. |
You enter what you know; it benchmarks the rest. The returns layer in particular is one almost nobody tracks honestly, which is why it has its own returns cost calculator.
Where your EBITDA
should land.
These are the bands the calculator grades you against. They are deliberately honest, because DTC profitability is thinner than the case studies suggest.
| Your EBITDA | What it means |
|---|---|
10% and above | Healthy, top half of DTC. Mid-teens and up is top-tier and gives you room to invest from profit, not debt. |
Around 5% | The DTC median: roughly 4 percent for seven-figure brands, 7 percent for eight-figure brands. Survivable, but one bad ad quarter from trouble. |
Negative | You are burning cash to trade. Find the leaking layer and fix it before you scale spend, or you just scale the loss. |
Notice the gap between the median and the case studies. Most of the brands you read about are quoting gross margin or a single great month, not a real twelve-month EBITDA. The public filings tell the same story: across the FY2025 10-Ks of 19 public DTC brands, the median operating margin was just 4.1 percent (Eightx, Public DTC Margin Leaderboard, SEC data, 2026). Benchmarking against the honest band keeps you from chasing a number almost nobody actually hits.
External data lands in the same place: DTC net margins realistically run between 3 and 10 percent once acquisition and overhead are in (Luca, Ecommerce Profit Margins, 2026). A brand quoting 20 percent is either pre-marketing-spend or rounding up.
The leak is almost
always one layer.
When a brand is unprofitable at a healthy gross margin, the culprit is usually a single layer that has crept out of line. Fulfilment that grew with AOV and never got renegotiated. A return rate nobody costed. A blended CAC that drifted past what the margin can carry. Overhead that scaled ahead of revenue. The calculator's job is to make that one layer obvious by showing each against its benchmark.
Once you know which layer it is, the fix has an address. A marketing leak sends you to max allowable CAC to reset your spending ceiling. A returns leak sends you to the returns calculator. A thin-revenue-per-visitor problem sends you to the conversion revenue leak calculator. Profit is a system, and you fix it one binding constraint at a time.
What it will not
do for you.
It is a model, not your accountant. It works off the inputs you give it, so garbage in is garbage out, and it will not reconcile to the penny against your books. It also takes a snapshot, while profitability is seasonal: a brand that lives or dies on Q4 needs to run it across the year, not on one good month.
What it does well is force the full stack into view and tell you which layer to interrogate. That is the hard part. The rest is operating discipline, and that is the work I actually do with brands.
Where it sits in
the toolkit.
The profitability calculator is the wide-angle view; the rest of the suite zooms into each layer. For the conceptual stack underneath it, read contribution margin for DTC and the profitability teardown. For the layers themselves: max allowable CAC for the marketing line, the returns calculator for the returns line, and the inventory cash-flow calculator for the cash the P&L does not show.
If you are not sure which layer to start with, run the growth scorecard first. It will tell you whether profitability is even your binding constraint right now, or whether something upstream of it is.
Common
questions
answered.
What's a good EBITDA margin for a DTC brand?
Ten percent or better is healthy and puts you in the top half of DTC. Mid-teens and up is top-tier. The median is closer to 5 percent, roughly 4 percent for seven-figure brands and 7 percent for eight-figure brands, which is survivable but fragile. Negative EBITDA means the model leaks somewhere between revenue and the bottom line.
What's the difference between gross margin and contribution margin?
Gross margin is price minus landed cost of goods. Contribution margin keeps subtracting the variable costs of the sale: fulfilment, payment fees, returns, and the marketing to acquire the order. Gross margin tells you the product works; contribution margin tells you the business does. The full stack is in contribution margin for DTC.
Why is my brand unprofitable at a good gross margin?
Because gross margin is the top of a long subtraction. A 65 percent gross margin can become negative EBITDA once fulfilment, returns, a high blended CAC, and fixed overhead come out. The calculator exists to show which of those four layers is doing the damage, since the fix is different for each one.
Is growth that loses money okay for a DTC brand?
Briefly and deliberately, yes. Permanently and by accident, no. Buying a cohort below contribution margin can be a sound land-and-retain bet if the repeat math is real. The danger is brands that lose money on every order and plan to make it up on volume, which only makes the losses bigger.
How do I calculate EBITDA for an ecommerce brand?
Start with revenue, subtract cost of goods for gross profit, then subtract fulfilment, returns, marketing, and operating overhead, before interest, tax, depreciation, and amortization. What is left is EBITDA, the cash the operation actually throws off. The calculator runs that stack for you in about a minute.
A brand that knows its real EBITDA and which layer is leaking can fix the leak. A brand that only knows its gross margin keeps scaling a problem it cannot see. Spend the sixty seconds: build your P&L and find the layer.
Scaling a consumer brand?
I work with a deliberately small number of DTC operators. I have run brands at this scale myself, from $5M past $100M. If you are in that range, the form takes two minutes.
