Doba just launched four free dropshipping tools: a Dropshipping Profit Calculator, a Break-even ROAS Calculator, an eBay Fees & Profit Calculator, and a Business Name & Logo Generator. All four deliver instant results, and the three calculators need no account at all; only the name and logo generator asks for a free sign-in. Here's what each one does, who it's for, and where to find it.
What Free Tools Does Doba Offer for Dropshippers?
Doba offers four free tools: a Dropshipping Profit Calculator, a Break-even ROAS Calculator, an eBay Fees & Profit Calculator, and a Business Name & Logo Generator, all with instant results and no sign-up required except for the name generator. Every one of them runs off the numbers you plug in, whether that's a product's cost and price, an ad budget, an eBay listing, or a description of what you're selling.
Dropshipping Profit Calculator
Before spending anything on a product, the Dropshipping Profit Calculator answers the question that actually matters: what's left after product cost, shipping, platform fees, and ad spend all come out. Run through a real example, a ceramic tumbler priced at $35 with a $9.50 cost, and the numbers land at $9.40 in net profit on a 26.9% margin, a very different picture than the $25.50 a naive sell-price-minus-cost estimate would suggest. That gap between the rough number and the real one is exactly what this tool is built to catch before it costs anyone money.
Who is this tool for? Anyone weighing whether a specific product is worth listing, especially before committing to a price point or turning on ads. The full field-by-field walkthrough, including how to read break-even price, is in How to Use Doba's Free Dropshipping Profit Calculator.
Break-even ROAS Calculator
Once a product's margins look solid, the next question is what return an ad campaign has to hit before it stops losing money. That's what the Break-even ROAS Calculator is for: enter cost, price, shipping, and fees, and it returns break-even ROAS, break-even ACoS, and the maximum you can spend per order and still come out ahead. In one worked example, a $32 water bottle with $17.40 of contribution margin needs a 1.84x ROAS just to break even, and about 2.91x to hit a 20% profit target.
This one's built for anyone already running or about to run paid ads, since a "good ROAS" only means something measured against a product's own numbers, not a benchmark borrowed from somebody else's store. The full explanation of break-even ROAS versus target ROAS is in What is ROAS & How to Use Our Free Break-Even ROAS Calculator.
eBay Fees & Profit Calculator
eBay sellers face a fee structure most profit math doesn't account for correctly: the final value fee is charged on the full amount a buyer pays, shipping included, not just the item price. The eBay Fees & Profit Calculator builds that in directly, returning the final value fee, any promoted listings cost, and the resulting net profit, margin, and ROI. A worked example with a $24.99 listing and free shipping comes out to $11.49 in net profit on a 46% margin, once the $3.80 in eBay fees is subtracted.
It's meant for anyone pricing or evaluating a listing specifically on eBay, where that shipping detail is the part most sellers miss doing it by hand. The full walkthrough is in the User Guide for Doba's Free eBay Fees & Profit Calculator.
Business Name & Logo Generator
Naming a store is usually the first real decision a new seller makes, and it's also where most free generators stop short. The Business Name & Logo Generator takes a product description and returns a dozen name ideas along with matching logo variants, then goes a step further by linking out to the actual checks worth running before committing to one, including a direct link to the USPTO's federal trademark database. In one example, a store selling durable dog products generated names like Ironhound and Noble Beast, with the federal trademark search confirming no existing registration on the name chosen.
This one is for anyone setting up a brand-new store who needs a workable name and a rough logo fast, without the budget or timeline for a full branding engagement yet. It's also the only one of the four that requires signing in with a free Doba account before it generates results. The full walkthrough, including all four checks worth running on a name, is in Build Your Brand with Doba's Free Business Name & Logo Generator.
Why These Tools Exist
Dropshipping rewards the sellers who do the math before spending money, not after. Margins, ad efficiency, and marketplace fees are the numbers that actually decide whether a store turns a profit, and these tools turn each of them into an instant answer instead of a spreadsheet built from scratch.
No Data Stored
The three calculators run entirely in the browser. Nothing typed into them is sent to Doba, nothing is saved, and there's no email wall standing between entering numbers and seeing results. The Business Name & Logo Generator works differently, since it sends a product description to generate names and requires signing in with a free Doba account first.
Where to Start
If you're sizing up a product, start with the Dropshipping Profit Calculator; it shows what's left after product cost, shipping, fees, and ads. Once ad spend is actually on the table, move to the Break-even ROAS Calculator to find the return an order needs to stay profitable. Selling on eBay adds its own fee structure, which is what the eBay Fees & Profit Calculator is for. And for a brand-new store, naming comes before any of it, which is where the Business Name & Logo Generator fits in.
Doba's Free Dropshipping Calculators vs. Paid Dropshipping Platform Features
These four tools are free without exception and always will be. They handle the math side of getting a product or a store off the ground: profit, ad return, fees, and a name to launch with. Doba's paid platform features sit on a different layer entirely, covering sourcing from 1M+ products, order automation, listing tools, and account management across the marketplaces a store actually sells on. The calculators answer whether a specific number works; the paid platform is what runs the store once it does.
Try Them
All four tools are live now, free, and ready to use on your own numbers.
