Margin after product, shipping & ad costs. The Dropshipping Profit Calculator takes selling price, supplier product price, supplier shipping, ad cost per order, payment and platform fees and returns profit per order plus net margin, break-even roas. Results update as you type, and the formula is shown under the result so you can repeat it in your own spreadsheet.
Online and retail margins are decided by the costs that are easy to forget: fees, shipping, returns, storage and advertising. Fill in every line, even with an estimate, before deciding what to sell and at what price. Use the worked example below to check the maths against your own figures.
How the Dropshipping Profit Calculator works
Dropshipping margins are decided by ad efficiency. The break-even ROAS tells you the minimum return your ads must achieve before any profit appears.
Worked example
With the example values (selling price of $40, supplier product price of $15, supplier shipping of $6, ad cost per order of $10, payment and platform fees of 3%), the profit per order is $7.80; net margin 19.50%, break-even roas 2.25x. Change any figure above and the result updates immediately; use Copy results to paste the summary into a note or email.

Frequently Asked Questions
How is profit per order calculated?
profit = price − product − shipping − ads − fees; break-even ROAS = price ÷ (price − product − shipping − fees).
Which figures do I need?
Selling price, supplier product price, supplier shipping, ad cost per order, payment and platform fees. Take them from the same period and the same set of accounts or reports so the ratio is consistent, and check the example values as a guide to the units expected.
Which fees should I include?
Every fee your platform or provider charges on a sale: commissions, payment processing, fulfilment, storage, advertising and the expected cost of returns. Fee schedules change, so check the current rate card.
