Countertop Cost Calculator
Build an installed countertop budget by measured area, material, market, demolition, and sink work.
Estimated countertop project cost
$3,300–$7,900
Planning range only. Local bids vary with labor availability, site conditions, access, product selection, and hidden repairs.
How the Estimate Works
The calculator multiplies measured countertop area by an installed range for the selected material. Optional demolition and sink work are added explicitly, then labor-sensitive costs are adjusted for the selected market. The range is intentionally wide enough to reflect fabrication, slab, edge, seam, and access differences.
Frequently Asked Questions
How do I measure countertop square footage?
Measure the length and depth of each rectangular countertop section in inches, multiply them, add all sections, and divide by 144. Measure islands separately and confirm the fabricator’s rules for overhangs and backsplashes.
Does the estimate include installation?
Yes. The material rates are installed planning ranges. Optional removal and sink cutout or fitting costs are added separately so the scope remains visible.
Why can two countertops of the same size cost differently?
Slab grade, pattern, thickness, edge profile, seams, cutouts, access, demolition, backsplash work, and local fabrication capacity can create large differences even when square footage matches.
Should I buy a slab from this estimate?
No. Use it to set an initial budget, then ask a fabricator to template the space and provide an itemized quote before ordering material.
