What kills dropshipping margins
The hidden killer is ad cost per order — your CPA. Product and shipping are predictable; acquisition cost isn't, and it's usually the biggest line. This calculator forces it into the math so your "profit" is real.

Frequently asked questions
How do you calculate dropshipping profit?
Profit per order = selling price − (product cost + shipping + ad cost per order + payment fees). Multiply by monthly orders for net profit. The ad cost per order (your CPA) is the line that sinks most dropshipping stores — it's easy to forget and often larger than the product cost itself.
What is a good dropshipping margin?
After ad spend, many sustainable dropshipping stores aim for 15-25% net margin. Gross margin (before ads) usually needs to be 60-70%+ to leave room for paid acquisition, because customer acquisition through ads is the dominant cost. Thin margins leave no buffer for refunds, returns or rising ad costs.
Why is my dropshipping store not profitable?
Almost always the ad cost per order (CPA) is too high relative to margin. Either the product's perceived value is too low to support a higher price, the creative isn't converting, or the audience is too expensive. Fixing creative and raising perceived value usually moves the needle more than cutting product cost.
How do I find profitable products?
Look for products competitors are scaling ad spend behind — sustained spend is a strong signal of profitability. WhatWins' Shop Tracker surfaces competitor stores, their ads and estimated spend, so you can spot winners before committing budget.
