Ordering too little siding stalls your project; ordering too much wastes thousands — our free siding calculator nails both the material quantity and the installed price. Enter your wall area (or just your home’s length, width, and height), pick vinyl, fiber cement, wood, or engineered wood, and get squares needed plus a realistic cost range instantly.
Every other siding calculator stops at “how many squares to buy” and leaves you guessing on price. Ours goes further: it applies current installed per-square-foot rates for all four major siding types, adds a 10% waste allowance, and breaks your estimate into materials and labor — the way contractors actually bid. Illinois homeowners, note the local labor and removal notes below.

How It Works
This siding calculator does what the big-box store tools won’t — it prices the job, not just the boxes:
- Enter your wall area two ways. Know your net wall square footage? Type it in. Don’t? Enter your home’s length, width, and total wall height — we compute the gross wall area, deduct 15% for windows and doors, and add a 10% waste factor automatically.
- Pick your siding. Vinyl is the budget king; fiber cement costs more but shrugs off Midwest weather; wood is beautiful but hungry for maintenance; engineered wood splits the difference.
- Get squares + cost instantly. See exactly how many squares to order (waste included) alongside an itemized materials-and-labor range.
What Affects Your Siding Cost
Two identical floor plans can price very differently. Run the siding calculator above with different materials to feel each factor:
- Siding material. The dominant lever — vinyl ($4–$10/sq ft installed) versus fiber cement ($8–$15) can double the project on the same walls.
- Wall area and house shape. More corners, gables, and bump-outs mean more cutting, more waste, and slower installation.
- Stories. Second-story walls need scaffolding or pump jacks, adding setup time and labor premiums of 15–25%.
- Old siding removal. Tearing off existing siding and disposing of it typically adds $1–$3 per square foot.
- Trim, soffit, and fascia. New corner boards, window wraps, soffit, and fascia are often quoted separately — ask what’s included.
- Insulation and housewrap. Adding insulated backing or premium weather barriers during residing boosts energy performance for a few dollars more per square foot.
- Color and profile. Dark or custom colors, wider exposures, and specialty profiles (board-and-batten, shake) cost more than standard white lap.
- Local labor rates. Experienced siding crews in Chicagoland and Lake County price above national averages — our calculator uses installed Midwest rates.
Siding Cost Comparison by Material
| Siding Type | Installed Cost per Sq Ft | Lifespan | Best For |
|---|---|---|---|
| Vinyl | $4–$10 | 20–40 years | Budget-friendly, low maintenance |
| Engineered wood | $6–$12 | 30–50 years | Wood look, better durability |
| Wood | $7–$14 | 20–40 years | Natural beauty, historic homes |
| Fiber cement | $8–$15 | 50+ years | Maximum durability, fire resistance |

Siding Calculator FAQs
What homeowners ask before residing:
Measure each exterior wall (length × height) and add them together, include gable triangles, subtract large windows and doors, then add 10% for waste. Divide the total by 100 to get “squares” — the unit siding is sold in. Our calculator above does all of this automatically.
Expect $12,000–$25,000 installed, with most homeowners paying around $17,200 for mid-range siding. Note that siding is priced by wall area — a 2,000 sq ft home typically has 1,500–2,500 sq ft of walls — at roughly $6–$15 per square foot installed depending on material.
Plan on 1,400–1,800 sq ft of siding material (14–18 squares including waste). Wall area runs larger than floor area because of wall height — a 1,200 sq ft ranch with 9-foot walls has roughly 1,500+ sq ft of walls before openings.
Vinyl is significantly cheaper — $4–$10 per square foot installed versus $7–$14 for wood. Vinyl also needs almost no maintenance, while wood requires regular painting or staining to reach its full lifespan, making vinyl cheaper over time as well.
Standard vinyl lap siding in a stock color is the cheapest professional option. You can trim costs further by residing in the off-season, keeping existing trim and soffit if sound, and getting multiple quotes — but avoid the cheapest bid if it skimps on housewrap and flashing.
A professional crew typically finishes in 1–2 weeks, including old siding removal and trim work. Simple ranch homes go faster; two-story homes with lots of corners take longer. DIY installations often stretch to several weekends.
