Black Granite Countertops Cost Guide 2026

Homeowners typically pay for black granite countertops based on material grade, edge profiles, and installation specifics. The price range reflects slab quality, thickness, and local labor rates. Budget estimates focus on the cost of material, fabrication, and professional installation.

Item	Low	Average	High	Notes
Material (slab)	$8 – $20	$15 – $40	$40 – $100	Black granite varies by origin and grade
Fabrication & edging	$15 – $40	$25 – $60	$60 – $120	Includes cutting, polishing, edge work
Seaming & fabrication waste	$0 – $6	$3 – $12	$10 – $25	Depends on layout
Installation & labor	$25 – $40	$40 – $75	$80 – $120	Per hour or per project
Templates & drawings	$0 – $2	$1 – $5	$5 – $10	May be included in install fee
Sealer & maintenance supplies	$0 – $3	$3 – $8	$10 – $20	Periodically required

Overview Of Costs

The total project cost for black granite countertops typically ranges from a low of about $2,500 to a high near $13,000, depending on total slab area, edge choices, and complexity. Common per square foot costs run roughly from $40 to $90 for installed countertops, with higher-end edges and premium slabs pushing toward the upper end. Assumptions include standard kitchen layout, standard 3 cm or 2 cm slabs, and installation by a licensed crew. Assumptions: region, slab grade, and install crew skills.

Cost Breakdown

What Drives Price

Key price influences include slab thickness, grade, color uniformity, and edge design. Thickness commonly appears as 2 cm or 3 cm, with 3 cm delivering a heavier look and greater edge variety. Regional costs also shift material availability and labor rates. Another driver is seam count; kitchens with long runs may require extra seams and waste management. These factors combine to create substantial variation across installations in the same metro area.

Ways To Save

Smart planning and upfront measurements reduce waste and additional trips for templating. Choosing a standard edge and avoiding premium inlays or rare color variations can markedly cut costs. Scheduling installation during off-peak seasons may yield favorable labor rates. If possible, selecting prefinished edges at purchase reduces on-site finishing time. Finally, consolidating multiple countertop surfaces into a single templated layout minimizes waste and labor hours.

Regional Price Differences

Prices shift across markets. In the Northeast, higher labor costs can lift installed ranges by about 5 to 12 percent relative to the national baseline. The Southwest often sees lower delivery fees and slab availability that can trim totals by 3 to 8 percent. Rural areas may experience longer lead times and shipping surcharges that offset some savings. Understanding local market variation helps set realistic expectations for total project cost.

Labor & Installation Time

Labor time depends on kitchen size, layout complexity, and edge profile. A straightforward 20 square foot run with a standard edge may take 1.5 to 2 days from templating to final sealing. Larger or irregular layouts can extend to 3 or more days. Efficient templating minimizes rework and keeps costs predictable.

Extra Costs & Hidden Fees

Hidden items often include templating fees, cutouts for sinks and faucets, and waste disposal charges. Some installers charge for haul-away of old countertops or for additional sealers if the job requires long-term protection. Ask upfront for a full line-item quote to avoid surprises.
