Quartz Countertop Cost Per Sq Ft Calculator
Enter your countertop area and instantly estimate quartz countertop supply and installation cost.
Quartz countertops are the most popular choice in US kitchen remodels — they offer the look of natural stone without the sealing and maintenance requirements. But quartz quotes range from $50 to $150+ per sq ft, and understanding what drives that difference helps you get the right product at the right price. Use this calculator to estimate your project cost before visiting showrooms or requesting fabricator quotes.

How much do quartz countertops cost per square foot?
Entry-level quartz countertops cost $50–$80 per sq ft installed, including fabrication and installation. Mid-range quartz runs $80–$120 per sq ft installed — the most popular price point for kitchen remodels. Premium and designer quartz (Calacatta marble looks, exotic patterns) costs $120–$175+ per sq ft installed. Edges, cutouts for sinks and cooktops, and backsplash panels all add to the total. Demolition and removal of existing countertops adds $5–$15 per linear foot.

What affects interior work cost per square foot?
Quartz brand & tier
Entry-level quartz (Silestone, MSI) starts at $50–$75/sq ft installed. Mid-range quartz (Cambria, Caesarstone) runs $75–$120/sq ft. Premium designer series with marble-look veining or exotic patterns (Calacatta Gold, Dekton) costs $120–$175+/sq ft installed.
Edge profiles
Standard eased and bevelled edges are typically included in the base price. Waterfall edges, ogee, or mitered edges add $15–$40 per linear foot. A 40 sq ft kitchen with 20 linear feet of premium edge profile adds $300–$800 to the total cost.
Cutouts & sink type
Each sink or cooktop cutout typically adds $100–$200. Undermount sinks require precise cutting and polishing of the exposed edge. Farmhouse/apron-front sinks require a custom front cutout — adding $200–$400 to the fabrication cost.
Countertop thickness
Standard 3/4 inch (2 cm) quartz is cheaper per sq ft. Premium 1.25 inch (3 cm) slabs cost $10–$20/sq ft more and are the standard for most modern kitchen installations. Mitered edges to create the appearance of 3 cm thickness add cost to 2 cm installations.
Old countertop removal
Removing existing laminate countertops is straightforward at $5–$10/linear foot. Tile or granite removal is harder at $10–$15/linear foot. Always confirm demo and disposal are included in the fabricator's quote — some quote supply and install only.
Fabricator & market
Local stone fabricators typically charge less than big-box store programmes. Urban markets run 20–40% above national average pricing. Getting 2–3 quotes from local fabricators who source from the same wholesale slabs is the best way to ensure competitive pricing.
Frequently asked questions
How much do quartz countertops cost per square foot?
Quartz countertops cost $55–$130 per sq ft installed including fabrication and installation. Entry-level quartz runs $50–$80/sq ft. Mid-range quartz costs $80–$120/sq ft. Premium and designer quartz reaches $120–$175+/sq ft. For a 40 sq ft kitchen, expect $2,200–$5,200 for a mid-range installation.
Is quartz better than granite for countertops?
Quartz is non-porous and never needs sealing — granite requires sealing every 1–3 years. Quartz is more consistent in pattern and colour since it is engineered. Granite has natural variation that many homeowners prefer. Both are similar in durability and price. Quartz is the more practical choice; granite has more natural character.
How do you measure countertop square footage?
Measure the length × depth (typically 25 inches for standard counters) of each counter section. Add the sections together and divide by 144 to get square feet. A kitchen with 8 ft + 6 ft of counter at 25 inches deep has (96 + 72) × 25 / 144 = 29.2 sq ft. Always add 10% for waste in the quote.
How long do quartz countertops last?
Quartz countertops are extremely durable and can last the lifetime of the home — typically 20–50+ years. They resist scratches, stains, and heat better than most natural stone. Avoid cutting directly on quartz and placing hot pans without trivets — these habits preserve the surface for decades.
Can quartz countertops be repaired if chipped?
Minor chips can be repaired with colour-matched quartz epoxy filler — a DIY repair costing $20–$50 in materials. Larger chips or cracks require professional fabricator repair at $150–$400. Deep cracks or damage near sink cutouts may require section replacement. Quartz is more chip-resistant than granite but not indestructible.
