Every product delivers 2 013 kr of contribution. Once acquisition cost is measured and sits comfortably below that, each sale funds the next one. The only decision left is how much of the profit we put back in.
3 295 kr incl. VAT, leaving 2 013 kr of contribution after COGS, logistics, shipping and fees.
Around 118 tkr a month. Roughly 100 products clears it, including marketing.
Keep it as profit, or spend it acquiring customers at a known cost. That choice is the flywheel.
Each krona reinvested buys contribution at a known cost. It runs until the factory or the ad auction stops it, and then the profit stays in the company.
Reinvesting more means spending more on marketing and ending up with more revenue and more cumulative profit, not less. Every line runs to the same ceiling, so the difference is how soon it arrives. Worth knowing: spending all the way to that ceiling maximises volume rather than margin, which is why the EBIT view is the honest one to look at.
How this is calculated. Revenue is 2 636 kr per product excluding VAT, of which 2 013 kr is contribution after COGS, logistics, shipping and fees. EBIT is contribution less 118 tkr of monthly running cost and less the marketing spend. Volume each month is the organic baseline plus whatever the budget buys at the paid CAC that applies at that volume. Month zero spends the paid volume times the paid CAC; every month after that we add the chosen share of EBIT to the next month's budget. Blended CAC is then simply the spend divided by every customer. Two things stop the wheel: capacity, and the point where one more paid customer would cost more than a product contributes. Illustrative arithmetic to show the shape of the mechanic, not a forecast.
Working capital. Growing means buying stock before we sell it. That is a real cash need, and it is not in here. EBIT is not cash.
Fixed cost stays at 118 tkr. Running at the ceiling would cost more than running at 200 a month. Optimistic, not careful.
Contribution stays at 2 013 kr. COGS should fall with volume, so this one works the other way.
No lag. A krona spent on ads becomes a customer and cash in the same month. In reality both take time.
No returns. There will be some.
No ramp friction. Trebling ad spend in one month is assumed to work as well as spending it steadily. Our budget ramps deliberately slower than this.
The flat line is deliberate. At nothing reinvested, growth is organic only. That is an assumption we chose, not a claim that nothing would happen.
