Vinyl Siding Cost per Square Foot Calculator
Cut through the averages and get your vinyl cost per square foot — material, labor and removal combined — based on your own measurements and rates.
Walls (feet)
Gables / triangles optional
Windows & doors to subtract
Tip: measure each wall's width × height at its widest points. A per-wall audit table appears below so you can check every number.

Why per-square-foot numbers vary so much
Search around and you'll see vinyl quoted anywhere from budget to premium per square foot. The spread is real: it reflects product grade, labor market, and how much trim and prep a house needs. A published average is a starting point, not your price. This page turns your actual area and rates into a per-square-foot figure you can defend.
Because siding is ordered by the square, the tool also reports cost per square (100 sq ft) — the unit contractors think in — so you can line up bids without doing mental math on the driveway.
A quick walk-through
Think of it as describing your house to the tool. First tell it what you're installing and in which units — that's the material dropdown and the feet/meters toggle. Then describe the walls: one row each for the front, back and sides, with the width, height and how many are the same.
Now the details that trip most people up. Any triangular gable goes in with its base and its height to the peak. Every window and door goes in as a size and a count so it's subtracted rather than covered. Last, choose how much waste to carry — 10% is the everyday figure — and, if you'd like a budget, add your labor and removal rates. Calculate, and read squares, panels, boxes, trim and cost in one place.
How reliable is this estimate?
Reliable enough to plan and shop with, and honest about its limits. The core arithmetic — area, openings, squares, waste — is exactly what an estimator or a building-supply desk uses, so the quantities are sound when your measurements are. The coverage and price defaults come from typical manufacturer specs and widely reported installed costs, not a single source, which is why we show ranges rather than false precision. Your final order should still be confirmed against a field measure and a real quote.
A few things worth confirming first
You've got a number — now protect it. These are the checks that keep a vinyl siding per square foot order from coming up short or over-buying.
- Confirm coverage: the default coverage is a planning figure. Check the exact coverage printed on your product's box or spec sheet and adjust it if it differs, since even a small change moves the piece count on a big wall.
- Match the waste to your walls: keep 10% for a simple rectangular house, and raise it toward 15% for gables, dormers, bay windows and lots of angled cuts, because those details generate short offcuts you can't reuse.
- Account for accessories: starter strip, trim, inside and outside corners, flashing and fasteners are all part of a complete order, not an afterthought — the takeoff above estimates each so your material list is whole.
- Keep a spare: hold back a piece or a full box for future repairs, since profiles and colors get discontinued over time and an exact match years later is hard to find.
- Time your order: have material delivered close to the start date, stored flat and dry, so it isn't sitting exposed or getting damaged before the crew arrives.
Re-run the numbers above after any change and lean on the per-wall audit to verify each surface one at a time, so what you order matches what the wall actually needs rather than a rough guess. That small habit is the difference between one clean delivery and a mid-project trip back to the supplier.
