How to use it
- Measure your exterior wall surface area in square feet and subtract major openings.
- Enter your expected cost per square foot, or keep the default $7.50 benchmark.
- Review your Estimated Total Cost instantly to establish your project budget.
Exterior renovations fail when material and labor costs catch homeowners off guard. The LP SmartSide Cost Calculator gives you an immediate, realistic estimate of your total project investment before you sign a contract. By multiplying your exterior wall square footage by your expected cost per square foot, you establish a firm baseline budget. If you do not have local labor quotes yet, the default rate of $7.50 per square foot provides a reliable midpoint within the standard $5 to $10 per square foot installed industry range. Knowing your estimated total cost puts you in control. You can compare contractor bids against real numbers, avoid overpaying for materials, and decide whether premium finishes or trims fit your budget. Use this baseline figure to secure financing, negotiate with builders, and ensure your home exterior upgrade finishes on budget without financial surprises.
Pro tips
- Add a 10% to 15% waste allowance to your square footage to cover cuts, angles, and gable ends.
- Round your measured square footage up to full board lengths to ensure you do not run short mid-project.
- Order all siding materials in a single batch to avoid subtle batch-to-batch color or texture variations.
- Remember to account for trim, soffit, and fascia separately if you plan to use specialized accent profiles.

Case study
Marcus needed new siding for his 2,000-square-foot home. Unsure if LP SmartSide fit his $16,000 budget, he used this calculator at the $7.50 midpoint rate, establishing a $15,000 baseline. Armed with that figure, he vetted three contractor quotes, eliminated an overpriced $22,000 bid, and signed a local installer for $15,200—keeping his project completely on budget.
