Concrete & Masonry calculators

Volume, slab, footing and masonry material calculators.

• Concrete Slab Cost and Volume CalculatorEnter any slab length, width, and thickness to calculate exact cubic yards, a separate allowance, the rounded ready-mix order, and an optional cost from the current supplier price you enter. The 12 × 12 ft example is editable.
• Concrete Volume CalculatorEnter the dimensions of your pour — rectangular or cylindrical — in feet and inches to get the cubic yards of ready-mix to order, with wastage and an optional cost estimate.
• Ready-Mix Concrete Cost Calculator — Complete Quote TotalTurn a current ready-mix concrete supplier quote into an itemised USD supply total while keeping physical volume, billed volume, fees and sales tax separate.
• Concrete Bag Calculator — 40, 50, 60 & 80 lbEnter a known concrete volume or rectangular pad dimensions, then compare up to three exact products using the mixed yield printed on each bag—not bag weight alone.
• Deck Mud Calculator — Square Feet, Thickness & BagsEnter known mortar-bed square footage directly or calculate it from length × width, then add compacted thickness, exact product yield, and allowance to get volume and whole deck-mud bags.
• Post Hole Concrete Calculator — Bags per Fence PostEnter each round hole's diameter and concrete fill depth, subtract the actual post displacement, then convert the project volume into whole bags using the yield printed on your product.
• Retaining Wall Block Calculator with Cap BlocksEnter the approved wall-face run and block-field height plus the exact installed wall-block and cap dimensions to produce separate course and cap takeoffs.
