The Margin Napkin.

Four numbers decide whether this is a business or an expensive hobby. This is where you find out which one you have... before you spend a dollar.

You are allowed to guess. If you haven't sourced anything yet, every number in here is a placeholder. That is the entire point. Get a rough answer now, then come back and replace the guesses with real quotes once you have them.

Your numbers

Look at what similar products sell for and pick one. You can move it later.
Just the product itself, straight from the factory. No shipping, no fees. If you have no idea, start at about a quarter of your price.
Where is it made?
Adds an estimate for freight and import duty on top of your unit cost.
What it costs you to get one unit to a doorstep. Set it to zero if the customer pays shipping.
The slice that quietly disappears to promo codes, refunds and damaged units.

The number that really matters

That is the absolute most you could spend to win one customer and still break even. Every ad, every discount, every free sample comes out of it. If it's small, you cannot buy growth... you have to earn it.

What the estimates are doing

Freight and duty are estimated as a percentage of your unit cost, because that is how they actually scale... a heavier, pricier product costs more to move and gets taxed harder. Overseas assumes 18%, nearshore 9%, domestic 3%. Real freight depends on weight, volume, season and your product's tariff code, so treat this as a placeholder until a freight forwarder gives you a real number.

Payment fees are estimated at 2.9% of the sale plus 30 cents, the standard published card rate most new brands land on.

Discounts and returns come off the top of your price, because a promo code and a refund both cost you revenue you already counted.

What this does not include: your ads, your software, your packaging design, your sample rounds, your time. Those all come out of what's left. That is why what's left has to be big.

The bands. Under 40% is thin... you will struggle to buy a customer profitably. 40 to 59% is workable but disciplined. 60% and up is where paid acquisition starts to make sense. These are rules of thumb for physical consumer products, not laws.

This is one lesson inside the Launch Accelerator.We take these four numbers and build your real cost sheet, your price, and your launch budget... line by line, with the sourcing to back them up.
