About ListCraft HQ

ListCraft HQ is a free suite of calculators and resources for marketers, ecommerce sellers, and freelancers. We build small, fast, single-purpose tools for the numbers people in marketing and online retail actually work with every day — things like return on ad spend, customer acquisition cost, and marketing ROI.

Every tool follows the same principles: it opens instantly, works without a signup, explains the underlying formula in plain language, and includes real-world benchmarks so the result actually means something.

Who it's for

Performance marketers, Shopify and Amazon sellers, agency teams, and independent operators who need a quick, trustworthy answer without digging through a spreadsheet or handing over their email address.
