What you keep after every cost of the order — product, shipping, fees, ads, returns and overhead. Margin is that profit as a share of revenue.
Net profit = Revenue − Total costs Margin = Net profit ÷ Revenue
Example: $100 − $68 = $32 profit → 32% margin
Margin compares profit to the selling price. Markup compares the price to what the product cost you. They are not the same number.
Markup = (Price − Product cost) ÷ Product cost
Example: $100 price, $30 product → 233.3% markup
The most you can spend to win one order before it stops making money. Spend less and the order is profitable; spend more and it isn't.
Max CAC = Revenue − All non-ad costs
Example: $100 − $48 = $52 per order
The return on ad spend your campaigns need just to break even. Ads reporting a lower ROAS are costing you money.
Break-even ROAS = Revenue ÷ Max CAC
Example: $100 ÷ $52 → 1.93x (rounded up to be safe)
The price that gives you a chosen margin. Percentage fees grow with the price, so the calculator solves for it exactly instead of guessing.
Lowest price where Margin ≥ Target
Example: 30% target → $96.78 per unit
Add an average returns allowance, the duties you pay, and your fixed monthly costs spread per order to see profit after everything.
Overhead per order = Monthly fixed costs ÷ Orders
Example: $3,000 ÷ 1,000 orders = $3 per order
It depends heavily on your category, price point and business model, so there is no single right number. Set the target margin slider to your own goal and the calculator shows the price and ad budget that reach it.
Margin is profit divided by the selling price; markup is the price increase over product cost, divided by that cost. A product that costs $50 and sells for $100 has a 100% markup but a 50% gross margin.
Break-even ROAS is the return on ad spend at which an order makes exactly zero profit. If your ads platform reports a ROAS below it, each order from those ads is losing money — even when revenue looks healthy.
Because platform and payment fees (and a percentage returns allowance) grow as the price grows. The calculator searches for the exact lowest price that still hits your margin after those fees, and rounds up so you never land just below it.
Per order. You pay to acquire the customer once, however many units they buy — so the calculator multiplies product price and cost by quantity, but not ads, shipping or packaging.
No. The calculation runs entirely in your browser; your prices and costs are never sent to ASSOSIATIX or anyone else, and no account is needed.
