Professional interior painting runs $2 to $6 per square foot of wall space, flooring installs for $3 to $24 per square foot depending on material, and sod costs $0.30 to $0.80 per square foot in materials, based on HomeImprovCalc's own 2026 cost model.

HomeImprovCalc's calculators and cost guides use consistent 2026 material and labor assumptions across every project type on this site, and this page collects them into one reference. Professional interior painting runs $2 to $6 per square foot of wall space, so a standard 12x12 bedroom costs $350 to $700 installed versus $100 to $150 in DIY materials. Flooring spans the widest range: laminate installs for $3 to $10 per square foot while solid hardwood runs $9 to $24. Carpet installs for roughly $3 to $9 per square foot, sod costs $0.30 to $0.80 per square foot in materials before installation, and gravel runs $25 to $60 per delivered ton. These are HomeImprovCalc's own published figures, not a third-party industry average, and they update whenever the underlying calculators or cost guides change. Use the table below for a quick lookup, or the calculators linked throughout this site for a number sized to your project.

Ranges reflect the material and installation variation this site's calculators and cost guides already account for: prep condition, regional labor rates, and product grade. Figures are national planning ranges, not a quote. Get local quotes before committing to a contractor.
Every figure in the table above is HomeImprovCalc's own published cost assumption, pulled directly from the calculators and cost guides already live on this site rather than an outside industry survey. The painting row comes from How Much Does It Cost to Paint a Room? (published 2026-06-17). The six flooring rows come from the material-by-material table on How Much Does Flooring Installation Cost? (published 2026-06-17). Sod materials and labor figures come from the FAQ data built into the Sod Calculator. Gravel pricing and the worked example come from the Gravel Calculator. Carpet's installed range in the table above uses the $3 to $9 per square foot figure published on the flooring cost guide; the Carpet Calculator's own FAQ cites a narrower $25 to $40 per square yard installed (about $2.78 to $4.44 per square foot), which sits inside the lower half of that range. Both figures are HomeImprovCalc's own numbers; we show the wider guide figure here for consistency with the other flooring rows and note the difference rather than picking one silently.
This page was published 2026-07-02 and reflects HomeImprovCalc's cost model as of that date. It is not based on a government dataset, a paid industry report, or a scraped competitor average. When Chris or the editorial team update a calculator's assumptions or a cost guide's figures, this page is the one that needs a matching update, since it is the single place all of them are collected.

Every figure on this page comes from HomeImprovCalc's own calculators and cost guides, not a third-party industry survey. Painting and flooring ranges are drawn from this site's dedicated cost guides; sod, gravel and carpet ranges come from the cost data built into each calculator's FAQ section.
This page reflects HomeImprovCalc's 2026 cost model as of July 2026 and is refreshed whenever the underlying calculators or cost guides change.
The table shows materials-only and fully-installed (materials plus labor) figures separately for each project, so you can see the labor share for that category.
