Methodology
Transparent calculation
BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.
Net area = perimeter × wall height + gable area − openings. Order area applies waste, cartons round up, and total cost adds siding, accessory allowance and entered labor.
FAQ
Siding Cost Calculator questions
Should all window area be deducted?+
Large openings are normally deducted, while small openings may be left in the waste allowance.
What does the trim allowance cover?+
It is a budgeting percentage for corners, starter pieces, channels and related accessories, not a detailed takeoff.
Does the estimate include removing old siding?+
No. Demolition and disposal should be added separately.
