Multiply the total run length (in feet) by the counter depth (typically 25 inches for standard or 26-27 for overhang). Add 10% for waste from seams, irregular cuts, and template adjustments.
Laminate costs $20-$40/sq ft installed, butcher block $40-$65, granite $50-$100, quartz $65-$120, and marble $80-$150+ installed. These include material, templating, fabrication, and installation.
| Material | Cost/sqft | Maintenance | Durability |
|---|---|---|---|
| Laminate | $20-$40 | Low | Fair |
| Butcher Block | $40-$65 | High | Good |
| Granite | $50-$100 | Medium | Excellent |
| Quartz | $65-$120 | Low | Excellent |
| Marble | $80-$150 | High | Good |
Standard kitchen countertop depth is 25-25.5 inches from the wall to the front edge. This accommodates standard 24-inch deep base cabinets with a 1-1.5 inch front overhang.
Standard eased or beveled edges are included in most quotes. Premium profiles like ogee, bullnose, or waterfall edges add $10-$30 per linear foot. A typical kitchen has 10-15 linear feet of finished edge.
