Countertop Cost Calculator
Estimate installed countertop cost — quartz, granite, or laminate — from counter length and depth and your material and labor rates per square foot.
How this calculator works
This estimates installed countertop cost from the counter’s surface area. It multiplies the counter length by its depth to get the area, then applies a material rate per square foot and a labor rate per square foot to that area separately before adding them together.
Formula: Total cost = counter area (length × depth) × material rate per sq ft + counter area × labor rate per sq ft.
Worked example
A 10 ft run at 2 ft standard depth (20 sq ft), $55/sq ft material (mid-range quartz), $25/sq ft labor:
- Counter area: 10 × 2 = 20 sq ft
- Material cost: 20 × $55 = $1,100
- Labor cost: 20 × $25 = $500
- Total estimated cost: $1,600
Notes
Quartz and granite run at similar mid-to-high price points per square foot, while laminate is far cheaper and a common budget choice. Edge profile upgrades and cutouts for sinks and cooktops add to the material rate beyond the flat per-square-foot number used here, so a finished quote from a fabricator may come in higher than this baseline estimate.
How to use
Measure your counter run’s length and depth in feet, then enter a material rate and labor rate per square foot based on your chosen material and a local contractor or fabricator quote. The calculator multiplies the area by each rate and adds them together for a total.
Estimates only. Actual cost depends on your region, material choice, and site conditions — get a contractor quote before budgeting.
Frequently asked questions
What depth should I use for a standard countertop?
Most kitchen countertops use a 25 to 26 inch depth, but a common simplified default is 2 feet (24 inches). Measure your actual counter depth if it differs, since a deeper counter or an island with overhang increases the square footage and total cost.
How does quartz compare to granite and laminate in cost?
Quartz and granite run at similar mid-to-high price points per square foot, since both are premium stone or engineered-stone materials. Laminate is far cheaper, making it a common budget alternative when the look of stone isn't a priority.
Does this estimate include a sink cutout or edge profile?
No. This calculator uses a flat material rate per square foot for the counter area only. Cutouts for sinks and cooktops, and upgraded edge profiles like bullnose or ogee, typically add to the material rate beyond the flat per-square-foot number shown here.
How do I measure counter length for an L-shaped kitchen?
Measure each straight run separately in feet, multiply each by the standard depth to get its area, then add the areas together before entering the combined square footage — or run the calculator once per run and add the totals.
