The interactive tool above is designed around one order. Enter selling price, supplier product cost, supplier shipping, payment or marketplace fees, advertising cost per sale, refund allowance and other variable costs. The sticky summary keeps the most important outputs visible while you change inputs: net profit per order, margin, break-even ad cost and break-even ROAS. This is useful when comparing suppliers or ad campaigns because a cheaper item is not necessarily a better item once shipping, payment fees and acquisition cost are included.
For example, if $20 remains after every non-ad cost on a $50 order, advertising can consume up to $20 before the modeled order reaches zero profit. Break-even ROAS would be 50 ÷ 20 = 2.5×. A campaign producing 2.5× ROAS would be near break-even under those assumptions; a higher ROAS provides more modeled contribution profit.
Assume a $50 selling price, $16 supplier cost, $5 supplier shipping, $10 ad cost per sale, a 3% refund reserve and $1 of other variable cost. If payment processing is modeled at 2.9% + $0.30, the payment charge is $1.75. Total modeled cost is $35.25 and estimated net profit is $14.75, giving a 29.5% margin. Before advertising, the order has $24.75 available, so its break-even ROAS is about 2.02×. If supplier shipping rises from $5 to $9 with every other assumption unchanged, profit falls to $10.75 and break-even ROAS rises. That sensitivity is why supplier comparisons should use delivered cost, not catalog price alone.
| Cost category | How to model it | Common mistake |
|---|---|---|
| Supplier product | Actual unit price paid | Ignoring variant or quantity pricing |
| Supplier shipping | Per-order fulfillment/delivery cost | Treating “free shipping” as zero cost to you |
| Payment / marketplace fee | Percentage plus fixed fee when applicable | Using a rate from a different country or plan |
| Refund reserve | Planning percentage of revenue | Assuming every refund has the same net cost |
| Advertising | Cost per acquired order | Using CPC without accounting for conversion rate |
Include product cost, supplier shipping, payment or marketplace fees, advertising cost per sale, returns/refunds and other variable costs tied to the order.
It is revenue divided by the maximum ad spend the order can support before modeled profit reaches zero. It changes whenever price or costs change.
Use the amount you expect to pay to fulfill the order, including supplier shipping and order-level charges.
No. Actual results can differ because of conversion rates, ad volatility, refunds, taxes, currency movements, chargebacks and supplier performance.
See the calculation methodology for rounding, assumptions and scope.
A lower product quote can be cancelled out by higher shipping, extra software or more refunds. Compare delivered cost and expected losses on the same selling price and advertising assumptions.
| Illustrative quote | Product | Shipping | Refund reserve | Profit on a $40 sale |
|---|---|---|---|---|
| Supplier A | $12 | $4.50 | 3% of sales | $11.84 |
| Supplier B | $10 | $7 | 3% of sales | $11.34 |
| Supplier C | $11 | $4 | 6% of sales | $12.14 |
Each scenario also includes $8 advertising, $1 other cost and 2.9% + $0.30 in payment fees. Supplier C is not a verified vendor or a recommendation: it is an invented example showing why the full cost stack matters. Software subscriptions and taxes are excluded and must be added separately.
Our contextual cards flag high product or shipping cost. They are prompts to compare workflows, not evidence that a partner is cheaper for your product. AutoDS is shown as a sourcing/workflow option for high product cost; Zendrop is shown for high shipping or fulfillment cost. The threshold does not measure product quality or guarantee savings.
Use the landed cost calculator for shipment-level duties and freight. Use Monthly Profit to include fixed overhead and Product Pricing to work backward from a target margin.
Illustrative arithmetic checked 4 September 2026. Partner prices, availability and eligibility must be confirmed on the partner website.
A $12 supplier item with $8 delivery costs more to deliver than a $14 item with $5 delivery. The worked $40 sale includes processing, expected losses and operating costs as well as the supplier total.
It leaves $14.04 before advertising. To retain $4 profit, acquisition must stay at or below $10.04 in that scenario. These are hypothetical figures, not supplier quotes or promised returns.
