Calculators

Real Numbers for Your Next Project

You don't need to guess. These are the same calculators I use myself — plug in your own project's numbers and get a real answer, not a rough guess.

🛠️ DIY vs. Hire Calculator — See exactly what you'd save doing it yourself, including what your own time is actually worth.

🎨 Paint Calculator — Get an accurate gallon count and cost for your whole project, room by room — including doors, windows, and trim most calculators skip.

🪵 Flooring Calculator — Figure out boxes, underlayment, and total cost before you're standing in the store aisle guessing.

All free, no login required. Want the full project guide to go with the math? Check out the Guides or join Toolkit for the complete library.
