How This Calculator Works
It takes your driveway's length × width × depth, converts that to cubic yards, and multiplies by the weight of crushed gravel (about 1.4 tons per cubic yard) to tell you roughly how many tons to order. Then it multiplies by your local price per ton for a material-cost ballpark. For a new driveway, 4 inches of gravel is a common starting depth; a refresh over an existing base can be less.
Important: this is a material-only estimate and a planning tool — not a quote. Delivery, base prep, grading, crowning, and compaction are priced separately, and every driveway is quoted as a whole after an on-site look, with a minimum job price. Prices per ton vary by supplier and location, which is why that field is yours to set.
Gravel Alone Won't Make a Driveway Last
The tonnage is the easy part. Whether a driveway holds up comes down to shape and drainage — a proper crown so water sheds to the sides, a solid base, and real compaction. Dump gravel into a rut without fixing the shape and it washes right back out. (Here's the full breakdown: why gravel driveways fail and how to fix them for good.)
