Free Tools For Fashion Brands
The calculators and templates we use with our own clients, free. No login, no email — your numbers stay in your browser.
Which tool should a fashion brand start with?
Start with the ROAS calculator. It tells you the break-even ROAS your margins, shipping, payment fees and return rate allow — the number every ad decision depends on. Once you know it, you can judge any campaign, any platform and any discount against it.

Why An Ad Agency Gives Away Calculators
Because most bad ad decisions start with the wrong number. A brand that knows its break-even ROAS stops scaling campaigns that lose money and stops killing ones that work. Every tool here connects to how we run accounts — the MoonDesk Scaling Method: know who buys, know the numbers, test, read and iterate.
Are the MoonDesk tools really free?
Yes. Every calculator works without a login or an email address. Some future tools will offer to email you a fuller version, but the result always shows first.
Do you store the numbers I enter?
No. The calculators run in your browser and don’t send your numbers to us. If you copy a share link, the numbers are in that link, so only share it with people you’d show them to.
Can I put a MoonDesk calculator on my own site?
Yes. Each calculator page has an embed code with a credit link back to the tool.
Who builds these tools?
The MoonDesk Media team — the same people who plan, create and manage Meta, TikTok, Pinterest, Google and Amazon ads for fashion brands. The formulas are shown on every tool page so you can check the math.
