About DIYSum

DIYSum helps homeowners and DIYers plan what to buy before heading to the store. Our promise is simple: Know what to buy before you buy it.

Measure. Calculate. Build.

Start with measurements, choose your material assumptions, then get a purchase quantity and optional cost estimate. Calculations run in your browser without an account.

What DIYSum covers

DIYSum includes calculators for concrete, paint, flooring, tile, drywall, mulch, gravel, fences, paver patios, square footage, board feet and cubic yards. Major project calculators separate measured quantities, allowances and purchase rounding so you can see how the result was reached.

Transparent assumptions

Local prices are yours to enter. Product coverage, bag yields, package sizes and supplier increments are editable where relevant. DIYSum is designed for planning, not as a substitute for product instructions, building codes or professional advice.

How the site is supported

DIYSum is currently free to use. The site may use advertising or affiliate links in the future to help support operating costs. Any such additions will be identified where appropriate and reflected in the Privacy Policy.
