Does it include underlayment?

No. Calculate underlayment separately because roll coverage and overlap requirements differ.

Can I deduct fixed furniture?

Make exclusions deliberately in your final measured takeoff if they are material to the project.

Laminate flooring calculator

Laminate floor coverage and whole-carton quantity with stated waste.

Calculator result and formula

Laminate cartons to order: 14 cartons

Formula: L × W × (1 + waste) ÷ stated coverage

Formula ID: FLOOR-LAMINATE-001 · Version 1.0.0 · Published · Last reviewed Aug 26, 2026.

Inputs

Floor length: Finished laminate floor length Default: 18.
Floor width: Finished laminate floor width Default: 14.
Carton coverage: Coverage stated on the selected carton Default: 20.
Waste factor: Allowance for cuts, pattern and spare stock Default: 10.

How this calculator works

This calculator converts measured floor area and an explicit waste allowance into whole laminate-carton quantity using selected-carton coverage.

Measure finished length and width.
Enter the carton coverage shown on the actual selected product.
Use a visible allowance for cuts, pattern, room geometry and spare stock.

Worked example: Example: an 18 ft × 14 ft floor is 252 ft². With 10% waste and 20 ft² cartons, it rounds to 14 cartons.

Assumptions and limitations

Coverage should use the selected manufacturer's product label or quoted net coverage.
Waste is added before whole-unit purchase rounding.
Complex layouts, seams or patterns can require a higher documented allowance.

Common mistakes to avoid

Confirm the measurement basis and units before using the result.
Keep waste or allowance visible and adjust it for the actual job conditions.
Confirm supplier packaging, delivery increments, specifications, and final site requirements before ordering.

Calculator disclaimer

This planning calculator does not determine structural design, code compliance, installation requirements, or guaranteed pricing. Confirm final requirements with the appropriate responsible professional, authority, manufacturer, and supplier.
