DeckCalc

Deck Cost Calculator

Pick the pricing basis that matches what you know — a board count, a price per square foot, or a full line-item budget.

Pick one pricing basis — the site never mixes a board-count price with a per-square-foot price in the same total.

How it works

The three modes are kept deliberately separate. If your board quantity already includes a waste allowance — like the recommended quantity from the Board Calculator — the “by board count” mode multiplies it by your price with no further waste adjustment, so waste is never counted twice. The per-square-foot mode applies waste once to the material cost, and never to labor. The detailed mode simply totals whatever line items you enter.
