Underlayment Calculation Formula

Total Area = Length × Width

Underlayment Needed = Total Area × (1 + Waste Factor/100)

Total Cost = Underlayment Needed × Price Per Sq Ft

Measure your room’s length and width in feet. Multiply to get total area. Add waste factor (typically 10-15%). Multiply by underlayment price to get total cost.
