Siding Cost Calculator: Estimate Your Project in 2026

Use this free calculator to get a quick, private ballpark for a new siding project in 2026. Enter your wall area — either in square feet or in squares (one square equals 100 square feet of wall) — choose your material, set how many stories your home has, and tell us whether the old siding needs to be removed and hauled away. The tool returns a low-to-high installed cost range using typical 2026 price bands. Everything runs in your browser; nothing is sent anywhere and no personal information is collected. Treat the result as a planning estimate, not a quote. Wall area is length around the house times wall height (subtracting large openings), so measure before you rely on any figure. When you are ready to buy, get at least three quotes from licensed local siding contractors.
