Countertop Cost Calculator
Estimate material + install cost by countertop type and square footage.
Typical kitchen counters run 25–40 sq ft. Measure length × depth of each run and add them up.
How to use this calculator
Pick your countertop material, enter the total countertop area in square feet, and choose an edge style. To measure, multiply the length of each countertop run by its depth and add the runs together. A standard base cabinet is about 25.5 inches deep, so a 12-foot run is roughly 25 square feet. Include an island if you have one, and don't subtract the sink or cooktop opening, since the cutout is part of the fabrication.
How this is calculated
The calculator multiplies your countertop area by a per-square-foot rate range for the selected material, which already includes fabrication and standard installation. Premium edge profiles (waterfall, ogee, bullnose) are priced per linear foot of edge, commonly $12–$35 or more, and add roughly $100–$700 to a typical kitchen, so the calculator applies a 10% adjustment to the total.
Example
A 30 square foot kitchen in quartz with a standard edge comes to $1,500–$6,000. Switching to a premium edge raises that to $1,650–$6,600. The same kitchen in laminate would be $750–$1,950, and in marble $1,950–$10,500.
Typical cost ranges
Laminate remains the budget option at roughly $25–65 per sq ft installed. Quartz and granite, the two most common upgrade choices, generally run $40–200 per sq ft depending on slab quality, brand, and edge detail. Natural marble ($65–350) and quartzite ($70–200) sit at the top of the range due to material cost and more careful fabrication, and rare slabs such as Calacatta marble or exotic granite can cost more still.
What can change the price
Seams, cutouts for sinks and cooktops, and unusual slab colors or veining can push costs toward the top of the range. Getting quotes from 2–3 local fabricators after running this estimate is the best way to pin down a firmer number. Ask each one whether the quote includes templating, delivery, cutouts, and removal of your old counters, so you can compare like with like.
