DropshippingProfit Checker.
Enter product cost, sale price, shipping, and fees. Get your profit per sale, margin, break-even ROAS, and a straight answer on whether the product can work on Google Ads.
Written by Christopher Krassnig, Founder & CEO of ZenoX Media. Built from the margin maths we run on 200+ ecom accounts.
The short answer
To check if a dropshipping product can work on Google Ads, take your sale price and subtract the product cost, the shipping you cover, and your payment fees. What is left is your profit per sale, and it is the most you can pay to win one order. Divide the sale price by that profit and you get your break-even ROAS. ZenoX runs this check on 200+ ecom accounts: the lower the break-even ROAS, the more room the product has on paid traffic.
The Math This Tool Runs
- Profit per sale =
- sale price - product cost - shipping you cover - payment fees
- Margin =
- profit per sale / sale price
- Break-even ROAS =
- sale price / profit per sale, which is the same as 1 / margin
- Max cost per sale =
- profit per sale. Pay more than this and the order loses money.
Worked example: a product you sell for 40, costing 12, with 5 shipping and 1.50 in fees. Profit per sale is 21.50, so the margin is 53.75% and the break-even ROAS is 1.86x. You can pay up to 21.50 to win one order. If the same product only made 8 profit, break-even would jump to 5.00x, and cold Google Ads traffic rarely clears that.

Why the margin decides everything
Most Dropshipping Products Fail on the Maths, Not the Ads
Your profit per sale is the most you can spend on ads to win one order and still break even. That single number sets your break-even ROAS, and your break-even ROAS decides whether Google Ads can ever make the product work.
A thin-margin product needs a very high ROAS just to break even, before you make a cent. Cold Google Ads traffic rarely clears that bar. A healthy-margin product gives you room to buy traffic and still profit.
So check the maths before you spend. If the break-even ROAS is too high, the fix is the margin - price, product cost, or recovered shipping - not another round of ad tweaks.
Common questions
Dropshipping Margins, Answered
- How do I know if a dropshipping product is profitable on Google Ads?
- Work out your profit per sale first: sale price minus product cost, minus shipping you cover, minus payment fees. That profit is the most you can spend on ads to acquire one sale and still break even. Turn it into a break-even ROAS by dividing the sale price by the profit per sale. A low break-even ROAS means the product has room to work on Google Ads. A high one - usually from a thin margin - means cold traffic will struggle to make it profitable. This free checker does the math for you.
- What is a good break-even ROAS for dropshipping?
- Lower is better, because a lower break-even ROAS means you have more margin to spend on ads. The bands this tool uses are our own rule of thumb from running ecom accounts, not a published benchmark: under about 2.5 usually leaves healthy room to run Google Ads profitably, roughly 2.5 to 5 is workable but tight, and above 5 means your margin is thin and cold Google Ads traffic will find it hard to clear that bar. If your break-even ROAS is high, fix the margin - price, product cost, or shipping - before you scale spend.
- Does this dropshipping profit checker store my numbers?
- No. Everything runs in your browser. Nothing you type is stored, sent, or logged anywhere. There is no login and no email required.
