2026 countertop cost calculator.
Enter your kitchen square footage, material, tier, and edge profile. We'll estimate installed cost based on a rolling survey of eighteen stone fabricators across the Southeast. Walk into the showroom with a number in your head — and recognize a quote that's way out of line before you sign.

How this calculator works
The price ranges come from a rolling quarterly survey of eighteen stone fabricators across Tennessee, Georgia, North Carolina, and Texas. We update the underlying numbers monthly. Reynaldo's shop, Sky Stone Granite in Murfreesboro, is one of the eighteen data points — he doesn't see the numbers from the other seventeen until we publish, which is the polite way of saying we don't let one fabricator's pricing skew the average.
The output is an estimate, not a quote. Real quotes price your specific slab, your specific cabinet layout, and the actual drive distance from the fab shop. Use this number to walk into the showroom prepared — not to negotiate against. If the showroom comes in 30% above this estimate, ask why. If they come in 30% below, ask what's missing from the quote.
What's in the number — and what isn't
Real quotes break into more line items than most homeowners expect. Here's exactly what our estimate covers.
-
✓Included in the estimate
Slab cost, fabrication labor, basic installation, edge profile (variable by selection), sink and cooktop cutouts as line items, and optional demo + haul-away if toggled on.
-
✕Not included — add to your budget
Plumbing reconnect ($150–$400 if you don't DIY), tile or full-slab backsplash (varies dramatically by selection), cabinet modifications, sales tax, and the first-year sealer on porous stones ($150–$300 when itemized — some shops include it).
How to turn this number into a real quote
Three steps between this calculator and an install date you trust.
-
1Verify your square footage
Use our square-footage calculator to confirm the number you entered. Most homeowners overestimate by 10–20% because they forget to subtract sinks and cooktops, or they underestimate by missing islands. The right square footage changes the estimate noticeably.
-
2Get three independent quotes
At minimum one independent fab shop, not three estimates from the same chain. Bring this number with you. The fabricator who comes in closest to the estimate without quietly cutting a line item is almost always the right pick.
-
3Walk the slab yard before signing
Even if you've picked the material and tier, the specific slab matters. Two "Calacatta-look" quartz slabs from the same brand can look noticeably different. The slab yard is the only place to confirm before you sign.
