Natural Stone & Countertop Calculators

Free, practical tools for planning a stone project — size a countertop and count slabs, estimate tile and sealer, weigh a slab before it moves, total your edgework, and budget the whole job before you call a fabricator.

Countertop Square Footage & Slab Yield

Total your countertop sections in inches, add a waste allowance, and see the square footage plus how many slabs the job needs.

Stone Tile Coverage Calculator

Turn an area and a tile size into an exact tile count and the number of boxes to buy, with waste built in for cuts and breakage.

Stone Sealer Coverage Calculator

Work out how many units of impregnating sealer to buy from your area, the product's coverage rate, and the number of coats.

Stone Slab Weight Calculator

Estimate what a granite, marble, quartzite, or quartz slab weighs — per slab and total — from its area, thickness, and density.

Edge & Backsplash Linear Footage

Add up finished edge and backsplash run — perimeter minus cutouts plus backsplash — and price the edgework by the foot.

Stone Countertop Cost Estimator

Add material, edgework, cutouts, and installation for a stone countertop, and see the total with a realistic low-to-high range.
