Product profit calculator: what does one order really leave you?

1. Price paid = selling price × (1 − discount). Your price = price paid ÷ (1 + GST). Orders that stay sold, as a % = that share × 100.
2. Blended RTO = COD share × RTO on COD orders + (1 − COD share) × RTO on prepaid orders. (An old share link with one RTO % uses it for both, so it gives the same answer as before.)
3. Orders that stay sold = (1 − blended RTO %) × (1 − returns %). The rest bring no revenue.
4. Revenue per order placed = orders that stay sold × your price.
5. Product cost counts only units that stay sold; returned units go back on the shelf, except the share you cannot resell.
6. Packaging and forward shipping are paid on every order dispatched, including the ones that come back.
7. RTO and returns add return shipping, plus product cost for units you cannot resell.
8. COD charge = COD share × COD orders delivered (1 − RTO on COD orders) × COD charge; gateway fee = prepaid share × price paid × gateway %. Marketplace commission = share that stays sold × price paid × commission % (a % of what the customer pays, on orders that stay sold).
9. Profit per order = revenue − product − packaging − shipping − returns − payment charges − commission − ads − other. Profit before ads = that + ad cost. Per order that stays sold = profit ÷ that share (no answer when none stay sold). Net margin = profit ÷ revenue × 100 (no answer without revenue).
10. What RTO and returns cost per order placed = (1 − share that stays sold) × (packaging + forward shipping + return shipping + product cost × % you cannot resell).
11. Break-even ROAS = price paid ÷ profit per order before ads (not reachable when that is 0 or less). Break-even price = the selling price at which profit per order is 0 (not reachable when profit does not rise with the price).
12. Profit a month = orders a month × profit per order − fixed costs; a year = × 12. Orders to cover fixed costs = fixed costs ÷ profit per order (0 with no fixed costs; never when each order loses money).
13. The month: ad spend = orders × ad cost per order; stock to buy = orders × product cost (returned units go back on the shelf, so the stock cost in profit is lower); order value = orders × price paid; revenue = orders × revenue per order; packaging and shipping = orders × (packaging + shipping + return shipping on what comes back); fees = orders × (payment charges + commission); GST = orders × share that stays sold × (price paid − your price); lost to RTO = orders × what RTO costs per order; all costs = orders × costs per order + fixed. Your ROAS = price paid ÷ ad cost per order (with no ad spend there is none).
14. Cash to run a month = ads + stock + packaging + shipping for every order, plus fixed costs: money that goes out before customers pay (COD money usually arrives days after delivery).

Green, amber and red compare each result with the break-even your own numbers imply, never with an outside benchmark. Every starting number is an editable example, not an industry average.
