Why we built these
Dropshipping rewards operators, not gamblers, and the difference is usually math done before the money goes out. These free tools turn the numbers that decide whether a store profits — margins, ad efficiency, marketplace fees — into instant answers. No email wall on the calculators, no guesswork.
Frequently asked questions
Are Doba's dropshipping tools free?
Yes. Every calculator on this page is 100% free with no sign-up — enter your numbers and get instant results. The Business Name & Logo Generator is free too, and asks you to sign in to a free Doba account before it generates. Doba also offers a broader set of platform features for product sourcing, research, and order automation as part of a paid subscription, but the tools here are always free to use.
What free dropshipping tools does Doba offer?
Doba offers four free dropshipping tools: the Dropshipping Profit Calculator for net profit and margins, the Break-even ROAS Calculator for ad efficiency, the eBay Fees & Profit Calculator for marketplace fees, and the Business Name & Logo Generator for naming and branding your store. Every tool is free and delivers instant results; the three calculators need no account, while the name and logo generator asks you to sign in to a free Doba account. Doba also publishes a free blog with dropshipping guides, supplier insights, and product-research tips, and more tools are on the way.
What tools do you need to start dropshipping?
At the planning stage you mainly need three things: a way to check whether a product still makes money after every cost, a way to know what return your ads have to clear before a sale is profitable, and a supplier you can rely on. The calculators here cover the first two — the Dropshipping Profit Calculator for unit economics, the Break-even ROAS Calculator for ad efficiency. If you sell on eBay, the eBay Fees & Profit Calculator handles that platform’s cut. For a brand-new store, naming comes before all of it, which is what the Business Name & Logo Generator is for.
Which dropshipping calculator should I use?
Start with the Dropshipping Profit Calculator if you are sizing up a product — it shows what is left after product cost, shipping, fees, and ads. Move to the Break-even ROAS Calculator once you are spending on ads and need the return that makes an order profitable. Use the eBay Fees & Profit Calculator when you sell on eBay, because the final value fee is charged on the total the buyer pays including shipping, which is the part sellers most often miss.
Are free dropshipping calculators accurate?
The math is exact — these are standard accounting formulas, not estimates. What decides whether the answer matches your reality is the numbers you put in, so use your real product cost, real shipping cost, and real ad spend rather than round figures. Where a calculator depends on an outside platform’s fee schedule, as the eBay one does, the rates ship as prefilled defaults that carry a visible date and stay editable, so you can replace them with the rates on your own account.
Do these tools store the numbers I enter?
No. The three calculators run entirely in your browser — nothing you type is sent to Doba, nothing is saved, and there is no email wall before you see results. The Business Name & Logo Generator works differently: it sends your product description to generate names, and asks you to sign in with a free Doba account first.
The numbers work better when you source on Doba
Source from 1M+ US-warehoused products with real markup headroom, fast 2–7 day domestic shipping, and no transaction fees — the foundation behind every number these tools calculate.
