Seven inputs you already know or can guess. The five numbers that run a product brand come out... before your dashboard exists.
Contribution margin is price minus the cost to make and deliver one order. It tells you whether one sale is worth making.
Net margin is what is left after ads and fixed costs, as a share of revenue. It tells you whether the business is worth running.
Cash on hand and the cash gap are not calculated here. Cash on hand comes straight off your bank balance. The cash gap is the days between paying for a production run and getting that money back in sales, and it lives in your dashboard.
LTV to CAC takes what a customer is worth over their life (contribution margin times orders per customer) and divides it by what you paid to win them (ad spend divided by new customers). Above 3 means growth is paying for itself. Below 2 means you are buying customers at a loss.
What this does not include: taxes, returns, and the cost of your own time. Those show up in the books, not in a napkin tool.
