As answered by people managing CalcRafter and Diffee.
CalcRafter's answer
US homeowners budgeting a project, DIYers working out what to order, and contractors or estimators checking a takeoff or a quote.
CalcRafter's answer
Next.js, React and TypeScript, deployed as a static site. Price data comes from the U.S. Bureau of Labor Statistics producer price index series.
CalcRafter's answer
Every calculator shows the formula it uses and lists its sources, so you can check the number by hand. The concrete and crushed stone prices aren't fixed guesses. They update monthly from U.S. Bureau of Labor Statistics producer price indexes, and the price history can be downloaded as CSV.
CalcRafter's answer
General calculator sites cover thousands of topics. CalcRafter covers only construction, so each page goes further: material quantity and typical installed cost together, worked examples for common sizes, and notes on waste, compaction and order sizes. It's free, with no signup and no ads.
CalcRafter's answer
Most construction calculators give you a number without showing where it came from, and their prices are often years out of date. CalcRafter started in 2026 to fix both: show the math on every page, and tie prices to official monthly data.
