Siding Cost Calculator
Estimate your total siding cost from the number of squares you are ordering and the installed price per square from your own quote. No price list is stored — the total is built only from the figures you enter.
Calculator
13.5 squares at your $450/square installed is about $6,075 (your rate — no price list is stored).
Once you know how many squares of siding a house needs, the cost is a single multiplication against the price your contractor or supplier actually quotes. This tool holds no price list of its own — material and labor prices change constantly by region, product and season, and any stored number would be wrong the day after it was entered. Instead, you type the installed price per square from your real quote, and the total follows.
Working from squares keeps every quote comparable. Whether a bid arrives as a lump sum or a per-square rate, converting to price-per-square lets you line contractors up side by side and see what you are really paying for the wall.
Formula
The estimate is one product:
total = squares × price per square
- squares — the amount you are ordering, waste included (from the squares calculator).
- price per square — your quoted installed rate: material plus labor for 100 sq ft of finished wall.
To convert a per-square-foot quote, multiply by 100: $4.50/sq ft is $450/square.
Worked example
Ordering 13.5 squares at a quoted installed price of $450 per square:
- Total: 13.5 × $450 = $6,075.
Change the price to match your own quote and the total updates — the figure is built entirely from your inputs, so it stays correct no matter how prices move.
Reading a siding quote
What an installed square price includes. A per-square installed rate usually bundles the field siding, basic trim and accessories, fasteners and the labor to hang it. What it may not include varies a lot: tear-off of the old siding, house wrap, insulation board, repairs to damaged sheathing, and specialty trim. Read each quote to see what is in the square price and what is a line item on top.
Compare apples to apples. Ask every bidder for a price per square, or convert their lump sum by dividing by your square count. A low headline number can hide excluded work; a higher one may already include tear-off and wrap. Per-square math makes the difference visible.
Why no built-in prices. This site chases no price list on purpose. Costs depend on your product, region, crew and the season, so the only accurate number is the one on your quote. Feeding your own rate in keeps the estimate honest and permanently up to date. Treat the result as a planning estimate, not a bid.
Frequently asked questions
How much does siding cost per square?
This tool does not store a price, because siding cost swings widely by product, region, crew and season — any stored figure would quickly be out of date. Enter the installed price per square from your own written quote and the tool does the rest.
How do I convert dollars per square foot to dollars per square?
Multiply by 100, since a square is 100 sq ft. A quote of $4.50 per square foot is $450 per square. Converting to a per-square rate lets you compare bids on the same basis.
What does an installed price per square include?
Typically the field siding, basic trim and accessories, fasteners and the labor to install them. It often excludes tear-off of the old siding, house wrap, insulation board and sheathing repairs — check each quote for what is bundled and what is extra.
How much does it cost to side a house?
Multiply the squares you are ordering by your quoted installed price per square. For example, 13.5 squares at $450 per square is about $6,075. Use your own rate so the estimate reflects your product and market.
Why does not the tool show a price?
By design. Real material and labor prices change constantly, so a built-in price list would be wrong almost immediately and would need endless updating. Working from the number on your quote keeps the estimate accurate and maintenance-free.
