Siding answer guide

How much does vinyl siding cost?

Estimate vinyl siding cost from net wall area, waste, siding squares, material, trim, housewrap, labor, and contractor total.

Reviewed - May 27, 2026

Short answer

Vinyl siding cost starts with net wall area, adds waste for the order quantity, then combines siding material, trim and housewrap allowances, and installation labor.

For a 160 linear ft perimeter with 9 ft walls, 180 sq ft of openings, and 10% waste, the calculator estimates 13.9 squares, a DIY material total of $3,717-$11,088, and a contractor total of $6,741-$18,018.

Keep the generated siding square count separate from the installed price: 13.9 squares is the field siding quantity, while the contractor range includes vinyl material, trim and wrap allowances, and labor but not removal or hidden repair.

Use the vinyl siding cost calculator

Vinyl siding cost method

Measure gross wall area from perimeter x wall height, wall-by-wall elevations, or a known net siding area.
Subtract window and door openings unless the known area already excludes them.
Add waste to the net wall area, then divide by 100 sq ft per siding square for the order quantity.
Estimate DIY material total from vinyl siding order area plus trim, housewrap, starter, corners, and fastener allowances.
Add vinyl siding labor based on net wall area to estimate a contractor total, then adjust for removal, repairs, access, and trim detail.
Keep siding panels, trim and wrap allowances, labor, old siding removal, disposal, and sheathing repair as separate lines when comparing installed prices.

Quick examples

120 linear ft vinyl siding

$4,387–$11,726

8 ft walls, 140 sq ft openings, 10% waste

160 linear ft vinyl siding

$6,741–$18,018

9 ft walls, 180 sq ft openings, 10% waste

1,500 sq ft known area

$8,025–$21,450

Known net siding area, 10% waste

1,260 sq ft higher-waste vinyl

$6,867–$18,396

Known net siding area, 15% waste

Walls plus two gables

$6,784–$18,133

40x28 ft shell, two 8 ft gables, 180 sq ft openings

These generated examples use the current U.S. default vinyl siding assumptions: 100 sq ft per siding square, trim and housewrap allowance, and vinyl labor range. Use the higher-waste example to compare cut-up elevations before treating a single installed square-foot price as final.

This example is generated from the same calculator logic used on the Siding calculator page.

Cost scope

DIY material total covers siding, housewrap, trim, starter, corner, and fastener allowances, not labor.
Contractor total adds directional vinyl siding labor, but removal, disposal, sheathing repair, permits, and complex flashing may need separate quote lines.

Area and waste

Use net wall area after openings for labor and trim planning, then use waste-adjusted order area for siding material.
Increase waste for many corners, short wall runs, gables, dormers, repairs, and product lengths that create extra offcuts.

Material grade and package coverage

Vinyl panel thickness, profile, color, insulation backing, wind rating, and warranty can move the material range even when square count stays the same.
Use the calculator square count for field siding, then check cartons, accessory pieces, starter strips, corners, and trim lengths before buying.

Quote comparison

Compare bids by measured net area, square count, panel grade, insulation backing, trim package, housewrap, flashing details, removal scope, and warranty.
A lower price can be incomplete if it excludes old siding removal, rotten sheathing repair, tall access, shutters, light blocks, vents, or permit fees.

Common mistakes

Pricing only vinyl panels and forgetting trim, housewrap, starter strips, corners, flashing, caulk, and fasteners.
Using floor area or house footprint as the siding area.
Comparing a DIY material range with a contractor installed quote.
Forgetting removal, disposal, sheathing repair, water-resistive barrier details, and tall access.
Using one square-foot price without checking what is included in the vinyl siding quote.
Assuming an installed per-square-foot quote includes old siding removal, wall repair, exterior insulation, or trim replacement.
Comparing quotes by total price without checking whether each bidder measured the same net wall area and waste scope.

FAQ

How do I estimate vinyl siding cost?

Measure net wall area, add waste for the siding order quantity, calculate vinyl material plus trim and housewrap allowances, then add labor for an installed contractor total.

How much does vinyl siding cost for 1,260 sq ft of net wall area?

With 10% waste under the current default assumptions, the generated example estimates 13.9 siding squares, $3,717-$11,088 for DIY materials, and $6,741-$18,018 for a contractor total.

Is vinyl siding priced by square foot or by square?

Both units are common. A siding square is 100 sq ft, while the calculator applies per-square-foot material and labor assumptions before showing the siding quantity in squares.

Does vinyl siding cost include removing old siding?

No. The calculator's contractor total is a planning range for new siding materials and labor. Existing siding removal, disposal, sheathing repair, and hidden damage should be quoted separately.

What does the generated contractor total include?

It includes vinyl siding material, trim and housewrap allowance, and siding labor from current calculator assumptions. It does not automatically include removal, disposal, sheathing repair, exterior insulation, permits, or specialty trim.

How does extra waste change vinyl siding cost?

For 1,260 sq ft of known net wall area, raising waste to 15% generates 14.5 siding squares and a contractor planning range of $6,867-$18,396 under current U.S. default assumptions.

Why do vinyl siding quotes vary?

Quotes vary because panel grade, wall shape, trim package, housewrap, flashing, story height, access, removal scope, sheathing condition, warranty, and local labor rates all change the job.
