What you can use today
HomeCostAI helps US homeowners turn measurements into material estimates. Our free calculators cover projects such as painting, flooring, tile, drywall, concrete, fencing, curtains, and garden beds. Each tool explains the inputs it needs and shows the assumptions behind its result. Our project guides help you measure and plan before you calculate.
Start with the calculator directory, choose the task you are planning, and check the result against product labels and your actual site conditions.
How to use an estimate
A calculator applies the measurements and options you enter to a stated formula. It can help you prepare a shopping list, compare package coverage, or spot a missing measurement. Real projects can differ because of layout, surface condition, installation method, waste, and product specifications. Review the tool's guidance and confirm quantities with the supplier or qualified professional when the decision matters.
What is coming next
Cost Estimators and the Quote Checker are in development. Their pages describe the planned workflows and offer a waitlist for launch updates. They do not currently generate a whole-project cost range or review a contractor quote.
Transparency and feedback
We aim to make useful assumptions visible rather than present a single number as a guaranteed outcome. For information on saved inputs and waitlist data, read our Privacy Policy. To report an unclear calculation or suggest a guide, visit our Contact page.
