Why This Calculation Matters

The Deck Cost Estimator helps you price and order materials correctly the first time. Short-ordering means extra trips, delays, and rushed decisions; over-ordering means wasted money and disposal hassle. A precise takeoff, plus a standard 10% waste factor, is the sweet spot.

Ordering & Waste Factor
