Estimate siding material and labor cost from your squares and your own supplier's price per square.
$5250.00
Siding material cost varies enormously by material type (vinyl, fiber cement, wood, metal all cost very differently) and by region, so this calculator never assumes a price -- it works out your squares from your wall area and openings, then multiplies by your own supplied price per square.
Enter your wall area, openings to subtract, the price per square your supplier or contractor has quoted, and an optional labor cost if that's billed separately.
Squares = (Net Area × 1.1) ÷ 100 (10% waste, rounded up)
Material Cost = Squares × Price per Square
Total = Material Cost + Labor Cost
This is a materials estimate based on the numbers you enter, not a full siding project quote -- removal of old siding, house wrap, trim, and disposal are common additional costs a full siding job may include, none of which are assumed here.
Say your net wall area is 1,800 square feet after subtracting openings. With the built-in 10 percent waste, that is 1,980 square feet, so the calculator rounds to 20 squares. If a supplier quoted 350 per square (a made-up figure for illustration), material cost would be 7,000. Adding a labor bid of 3,000 gives a total of 10,000. The point is not those numbers, but that changing any one input moves the result in a predictable way, so you can compare quotes quickly.
Real projects frequently include demolition of old siding, disposal, sheathing repairs, house wrap, flashing, trim, permits, and painting for materials that need it. None of those are added here. If you want a more complete budget, list them separately and add your own supplier quotes for each. It is also wise to keep a contingency, since hidden damage under old siding is a well-known source of surprises.
This version applies a 10 percent waste allowance behind the scenes. If your house has many corners or a complicated design, your true needs may be higher, and if it has simple, mostly flat walls, they may be slightly lower. To test a different waste percentage, use the Siding Calculator to find your squares first, then multiply by your price and add labor manually.
Treat the total as a planning figure to sanity-check bids, not as a contractor quote. Bids that are far above or below your estimate are worth asking questions about, since the difference often comes from scope rather than the material price itself.
When you gather quotes, note the date, the product line, the color, and whether the quote assumes any removal work. Prices for building materials can change over a season, so a quote from months ago may no longer apply. Re-running the calculator with a fresh price takes only a few seconds and keeps your budget current.
Vinyl, fiber cement, wood, and metal siding all have very different material costs and installation labor requirements -- there's no single "siding price" that applies across material types.
No -- add tear-off and disposal cost to the labor/other-costs field if you want it reflected in your total estimate.
Because labor, if entered, is added on top of the material cost. Leave labor at zero to see the material figure alone.
Per square, which is 100 square feet. If your quote is per square foot, multiply it by 100 first.
No. Add any applicable tax yourself or ask your supplier for a tax-inclusive quote.
