Countertop Calculator
Calculate the materials and costs for your countertop project. Enter your countertop dimensions, select material type, edge profile, and cutout options to get accurate estimates for granite, quartz, marble, and other countertop materials.
Main Area = Length × Width
Island Area = Island Length × Island Width
Total Area = Main Area + Island Area
Linear Feet = Perimeter (all edges)
Material Cost = Area × Price per sq ft
Edge Cost = Linear Feet × Edge profile price
Total Cost = Material + Edge + Cutouts + Installation
Example:
Main Counter: 10 ft × 2 ft = 20 sq ft
Island: 5 ft × 3 ft = 15 sq ft
Material: Quartz ($75/sq ft)
Edge: Bullnose ($8/ft)
Cutouts: 1 sink ($100)
Total Area = 20 + 15 = 35 sq ft
Perimeter = 34 linear feet
Material = 35 × $75 = $2,625
Edge = 34 × $8 = $272
Installation = 35 × $35 = $1,225
Total = $4,222
