Aluminum Siding Cost Calculator
An aluminum siding quote is really eight smaller prices wearing a trench coat: panels, waste, removal, trim, labour, fasteners and underlayment, permits, and the complexity of your house. This aluminum siding cost calculator prices each one openly. Enter your home’s length, width, wall height and stories, subtract windows and doors, then pick a grade and panel thickness. The tool prices removal by the type of siding coming off, weights labour hours by how complex the home is, and checks your finished price per square foot against the typical installed range.
The calculator is pre-filled with a worked example you can audit line by line: a single-storey 36 by 28 ft home with 8 ft walls and 180 sq ft of windows and doors, economy grade at the common 0.024 in thickness, basic trim, no removal, a 10% waste allowance, labour at $40 an hour and a $100 permit. It returns a total of $8,897.20, or $10.54 per square foot over 844 sq ft of net wall. Every line of that breakdown is printed below, and the full cost-breakdown table further down shows where each dollar goes.

Quick Answer
Worked example: the full cost breakdown
The calculator above is pre-filled with this exact job, and every figure in the table is what it returns when you press Calculate. Start with geometry: perimeter = 2 × (36 + 28) = 128 ft. Gross wall area = 128 × 8 × 1 storey = 1,024 sq ft. Subtract 180 sq ft of windows and doors and the net siding area is 844 sq ft. Economy grade at 0.024 in prices at $4.25 per square foot in the tool's rate matrix, so materials = 844 × $4.25 = $3,587.00.
| Cost line | How it is figured | Amount |
|---|---|---|
| Materials | 844 sq ft × $4.25 (economy, 0.024 in) | $3,587.00 |
| Waste / overage | 10% of materials | $358.70 |
| Old siding removal | None selected | $0.00 |
| Trim and accessories | 128 ft perimeter × $8 (basic) | $1,024.00 |
| Labour | (844 × 0.08 + 128 × 0.15) × 1.0 = 86.7 hrs × $40 | $3,468.80 |
| Fasteners, underlayment, extras | 10% of materials | $358.70 |
| Permits | Flat entry | $100.00 |
| Total | Sum of the lines above | $8,897.20 ($10.54/sq ft) |
Read the shape of that split, not just the total. Materials and labour together are about 79% of the job, and they scale with wall area. Trim scales with perimeter, which is why a small home with lots of corners can price higher per square foot than a big plain box: this example's $10.54 per square foot sits just over the benchmark ceiling mostly because 128 ft of trim is spread across only 844 sq ft of wall. Double the house and the same trim logic dilutes fast.
How the math works, line by line
The tool builds the job in the same order a contractor scopes it: measure, price panels, add the work around the panels. Each line below is a formula the calculator actually runs, with the rate tables it uses printed in full so you can audit any quote against them.
| Grade | 0.019 in | 0.024 in | 0.032 in | 0.040 in |
|---|---|---|---|---|
| Economy | $3.50 | $4.25 | $5.00 | $5.75 |
| Standard | $4.50 | $5.25 | $6.00 | $6.75 |
| Premium | $6.00 | $6.75 | $7.50 | $8.25 |
| Architectural | $7.50 | $8.25 | $9.00 | $9.75 |
Removal rates by old material: vinyl $1.50, aluminum $1.75, wood $2.25, brick $3.50, stucco $4.00 per square foot. Trim tiers per foot of perimeter: basic $8, standard $12, premium $18, custom $25. Complexity multipliers on labour hours: simple 1.0, moderate 1.3, complex 1.6, very complex 2.0. When a contractor's quote lands far from this tool's output, these tables tell you which assumption differs: ask which line moved, and by how much.
Gauge and grade: what the numbers buy you
Thickness is the decision with the longest shadow. The 0.019 in panel is thin enough to dent from a ladder foot or a hard hailstone, and a dent in aluminum is permanent: unlike vinyl, it does not flex back. The 0.024 in panel is the common residential compromise, stiff enough for normal life at a mid price. At 0.032 and 0.040 in you are buying dent resistance and a flatter, less wavy wall, which matters most on wide sun-facing elevations where thin panels oil-can in the heat.
Reasons to go thicker or insulated
- Hail-prone regions and walls facing driveways, courts and play areas.
- Wide flat elevations where thin panels ripple visibly in sunlight.
- Insulated backing stiffens light panels and quiets rain noise noticeably.
Reasons to stay at 0.024 in standard
- Sheltered walls and rental properties where upfront cost rules.
- Homes likely to be repainted: aluminum takes paint well, so colour changes do not need new panels.
- Budgets where the money does more good in trim and proper flashing.
Grade is mostly finish and warranty: higher tiers buy better paint systems, deeper embossing and longer colour warranties rather than different metal. If you are pricing the other big metal exterior job at the same time, the metal roofing cost per square foot calculator uses the same per-square-foot method, and it pairs naturally with a siding quote from the same contractor.
Reading your per-square-foot result honestly
The verdict badge compares your finished figure with the typical installed range this tool uses, $5.50 to $10.50 per square foot. Published ranges disagree more than most homeowners expect. The RemodelingExpense aluminum siding calculator puts installed aluminum at $8 to $15 per square foot, Homewyse's unit-cost method averages $8.87 to $14.78, and national-average tables run as low as $4.55 to $8.12. The spread is mostly labour geography and what each source counts as included.
Use the badge as a question generator, not a grade. Below the range usually means something real is missing: labour at zero, removal skipped, or trim forgotten. Above the range is common and often legitimate for premium or architectural panels, stucco removal, or a complex two-storey home, and the line items show you exactly which driver did it. What should worry you is a contractor quote that is above the range with no line able to explain why. Homeowners repainting sound aluminum instead of replacing it can price that smaller job with the paint cost per square foot calculator, and the same measure-then-multiply discipline prices interior work through the drywall cost per square foot calculator.
What competing calculators miss
The rival tools fall into two camps: range calculators that want your ZIP code and email, and flat-rate calculators that multiply one area by two rates. Both leave the actual job unpriced.
Winning move 1: grade and thickness as a real matrix. No competitor in the top results prices panels from grade and thickness together, yet that choice alone swings materials from $3.50 to $9.75 per square foot in this tool's matrix, a $5,277 difference on the worked example's 844 sq ft. A calculator that asks for "material quality: low, medium, high" is hiding the single biggest lever in the job.
Winning move 2: removal priced by what is coming off. Tearing off stucco costs over twice tearing off vinyl in labour and disposal, and most rival tools either ignore removal or fold it into a flat fee. Here it is its own rate table, and it adds its own labour hours (0.03 per square foot) on top of the per-foot price.
Winning move 3: labour built from hours and complexity. Flat labour per square foot cannot tell a plain ranch from a cut-up two-storey with dormers. This tool builds hours from wall area, trim length and a complexity multiplier, so the labour line moves for the reasons a real crew's bid moves. The benchmark verdict then tells you whether the assembled job still sits inside the typical range.
Frequently asked questions
In this calculator's benchmark, a typical installed job lands between $5.50 and $10.50 per square foot, and the worked example on this page prices out at $10.54 per square foot for an economy grade job with basic trim. Published guides disagree: some put aluminum as low as $4.55 to $8.12 per square foot installed, while contractor-cost sites put it at $8 to $15. Your grade, thickness, removal work and local labour rate decide where you land, which is why this tool prices line items instead of quoting one range.
0.024 inch is the standard residential choice and the default in this calculator. Go to 0.032 or 0.040 inch in hail-prone areas or anywhere ladders, balls and garden tools regularly hit the walls, because thicker panels resist dents far better. The 0.019 inch stock is budget material: it is the cheapest per square foot and the easiest to dent, and most homeowners who choose it for a whole house regret it at the first hailstorm.
Ten percent is the standard allowance for a simple rectangular home, and it is the default in this calculator. Gables, dormers, bay windows and diagonal cuts push the real figure toward 15%. The waste line here is priced on materials only, which matches how contractors order: you buy extra panels, you do not pay extra installation hours for the offcuts.
Not always. Aluminum can sometimes be installed over flat, sound existing siding, and skipping removal saves $1.50 to $4.00 per square foot in this calculator's rates. Removal is the safer default when the old siding is warped, rotted or hiding wall damage, because new panels telegraph every bump underneath them. Stucco and brick removal cost the most because of weight and disposal.
Insulation backing adds $1.25 per square foot in this calculator. It stiffens the panels, which cuts denting and oil-canning, and it adds a modest thermal layer. The honest payback is mostly comfort and rigidity rather than energy savings alone. On a thin 0.019 or 0.024 inch panel it also buys back some of the dent resistance you gave up by choosing a lighter gauge.
In the worked example, labour is $3,468.80 of the $8,897.20 total, about 39%. Siding is hand work: measuring, cutting, levelling and fastening every course, plus trim around every opening. This calculator builds labour from hours (0.08 hours per square foot of wall, plus trim time per foot of perimeter, weighted by home complexity) instead of a flat per-foot guess, so a complex two-storey home prices very differently from a simple ranch.
Aluminum usually costs more than vinyl per square foot installed, and it can be repainted when the colour tires, which vinyl generally cannot. Vinyl wins on upfront price and dent forgiveness, since it flexes instead of creasing. Aluminum wins on heat resistance and longevity in hot climates. Price both with the same wall measurements before deciding; the gap is often smaller than people expect once trim and removal are counted.
A confident DIYer can side a simple single-storey wall, and this calculator lets you test that honestly: set the labour rate to zero and the total drops to materials, waste, trim and permits only. What DIY does not remove is the waste risk. A mis-cut panel order at 10% allowance leaves no slack, and most first-timers should budget 15% and a weekend more than planned.
