How to calculate dropshipping profit per order after ads and fees
Start with the customer-paid selling price, remove included sales tax, then subtract supplier cost, shipping, fulfillment, expected returns, payment fees, marketplace fees, creator commission, and other variable costs. The amount remaining before advertising is the break-even CPA. Subtract the actual CPA to find first-order profit.
This workflow keeps percentage fees and fixed fees separate because both matter at lower selling prices. It also keeps CPA as a direct input, which makes it useful for testing a product or offer before committing to a larger media budget.
Profit per order = net sales − non-ad variable costs − CPADropshipping product testing example before scaling
Suppose an offer sells for $60 before sales tax. Supplier cost is $18, shipping is $6, payment and platform fees total $5, and the expected return allowance is $3. Non-ad variable cost is $32, leaving a $28 break-even CPA.
At a $22 actual CPA, first-order profit is $6 per order, actual ROAS is 2.73x, and break-even ROAS is 2.14x. At 400 monthly paid orders, the same assumptions imply $2,400 contribution after ads before fixed overhead. The projection is arithmetic, not a forecast of demand, conversion rate, refunds, or auction cost.
Shopify, TikTok Shop, and Amazon dropshipping fee scenarios
The store presets populate editable example assumptions for common payment, marketplace, commission, and fulfillment patterns. They are starting points, not published or guaranteed fee schedules. Actual rates vary by plan, region, category, processor, promotion, and seller agreement.
After selecting a preset, replace every fee with the value from your own statements. A creator-led TikTok Shop offer may carry both marketplace and creator commission, while an Amazon offer can have a larger platform percentage and fulfillment charge. A direct Shopify store may shift more of the cost into payment processing and paid acquisition.
First-order dropshipping profit vs customer lifetime value
First-order profit is the contribution from the acquired order after its direct costs and CPA. Customer lifetime value adds expected contribution from future orders and must account for repeat rate, timing, retention cost, refunds, and the risk that a new customer never purchases again.
Use first-order economics as the default guardrail for a new product. Accept a lower first-order result only when cohort data supports the repeat contribution and the business can fund the payback period. A projected lifetime value is not a reason to ignore a pre-ad loss or an unvalidated acquisition funnel.
How CPA and break-even ROAS decide if a dropshipping product can scale
Break-even CPA is the most advertising cost one order can absorb before first-order contribution reaches zero. Break-even ROAS divides reported order revenue by that CPA. Actual CPA below the ceiling and actual ROAS above the floor indicate positive first-order contribution under the entered assumptions.
Monthly projections multiply the same per-order model by expected order volume. They do not forecast auction prices, conversion rate, refunds, inventory availability, chargebacks, or fixed overhead, so test conservative and optimistic input sets before scaling.
Dropshipping product profit calculator FAQ for paid advertising
What costs should a dropshipping profit calculator include?
Include supplier cost, outbound shipping, fulfillment or agent fees, payment processing, marketplace fees, creator or affiliate commission, expected refunds, chargebacks when material, and advertising CPA. Allocate fixed overhead separately if each paid order must help cover it.
Is ROAS or CPA better for dropshipping product testing?
Use both. CPA gives a direct per-order acquisition cost, while ROAS makes campaigns with different selling prices easier to compare. Both must use the same order value and attribution scope.
Are the Shopify, TikTok Shop, and Amazon preset fees current?
No. They are editable planning examples that demonstrate different fee structures. Replace them with the rates from your current platform, category, country, processor, and seller agreement.
