Marketing & Business
Margins, ROAS, break-even and campaign tools.
Marketing and business tools handle the everyday math and setup behind running a product or a campaign. This category covers the numbers that decide whether something is worth doing: profit margin, markup, break-even, ROAS, CPM, CAC, CPA, and conversion rate, along with a UTM link builder, a landing-page ROI estimate, and a subject-line check. Founders, marketers, and small-business owners reach for these when pricing a product, planning ad spend, or working out whether a campaign paid off.

Frequently asked questions
- Are these marketing calculators free, and is there a sign-up?
- All of the marketing and business tools here are free, with no account or sign-up needed. There are no usage limits, so you can run the same margin or ROAS calculation as many times as you like while you test different numbers. Nothing is held back behind a paywall.
- Do I need to install any software?
- No. These marketing tools run in a normal web browser on desktop or mobile, with nothing to download or install. Most of them run entirely in the browser, so you type your figures in and the result updates on the page.
- Is it safe to enter my numbers, like costs and ad spend?
- These calculators run in your browser, so you type your figures in and the result is worked out on the page. You do not need an account, and you are not asked for anything beyond the numbers a given calculation needs. There is no personalized financial advice here, just the arithmetic you would otherwise do by hand.
- Which calculator should I use for which job?
- To price a product, start with the Markup Calculator and Profit Margin Calculator, then use the Break-even Calculator to see how many sales cover your costs. For advertising, the ROAS, CPM, CAC, and CPA calculators measure what your spend returns, while the Conversion Rate Calculator and Landing Page ROI look at how well traffic turns into sales. The UTM Builder tags your links so you can tell where that traffic came from, and the Subject Line Tester checks an email subject before you send it.
