Editorial interest 84/100 Selection signal · not a rating of the site

A set of DIY calculators estimates materials, costs, waste, store-sized quantities, and—in the deck calculator—a framing layout.

Landing page captured for the 2026-09-18 issue.

For: DIY homeowners planning material purchases
Worth noticing: Results use real store sizes, visible waste allowances, local price adjustments, and cited construction sources.

Field notes

The site organizes its estimates around purchasable units rather than abstract volume: bags, boxes, sheets, boards, and gallons. It exposes waste allowances and allows price changes for local conditions, while its source notes identify manufacturer data sheets, retail listings, cost guides, and building references. The homepage reports 63 tracked prices and 119 cited retailers, makers, and codes, with prices marked as collected September 17, 2026.
