Gravel driveway cost per square foot
Reviewed 2026-07-04 · Prices are ranges; your local quarry sets the real number
Plan on $1 to $3 per square foot DIY (materials delivered) and $2 to $5 per square foot installed, for a proper 4 to 6 inch build. Depth drives cost more than stone choice: at 6 inches you're buying about 0.028 tons per square foot. Stone is cheap; trucking is what you're really paying for.
Cost by build depth
| Build | Depth | Tons / 100 sq ft | DIY $/sq ft | Installed $/sq ft |
|---|---|---|---|---|
| Top-up of existing drive | 2″ | 0.9 | $0.25–0.55 | $0.75–1.50 |
| Light-duty, firm soil | 4″ | 1.8 | $0.50–1.10 | $1.50–3.00 |
| Standard 2-layer | 6″ | 2.8 | $0.80–1.70 | $2.00–4.00 |
| Heavy / soft soil, 3-layer | 8″ | 3.7 | $1.10–2.30 | $3.00–5.00 |
Tonnage & cost calculator
Call your nearest quarry. This number varies more than any other.
Tons = cu yd × 1.4 (crushed stone). Get delivery quotes for the full tonnage; two smaller loads often cost more than one big one.
The layer system (why cheap driveways fail)
A driveway that holds up is three sizes of stone doing three jobs. Base layer: large #3 stone (2 to 4 inch) that locks into the subsoil. Middle: crusher run or #57 that fills the gaps. Top: crushed stone with fines that compacts into a hard surface. Each layer gets compacted before the next. Dump one load of pretty stone on dirt and the soil eats it in two winters. That's not a myth; it's why "adding gravel every year" is a thing people complain about.
Frequently asked
How much does a 12x50 gravel driveway cost?
That is 600 square feet. DIY with a proper 6 inch two-layer build: roughly 17 tons of stone, which lands between $700 and $1,700 delivered depending on your local rock prices and delivery distance. Installed by a contractor with grading: typically $1,500 to $3,000.
How many tons of gravel do I need per square foot?
At 4 inches deep, about 0.018 tons (36 lb) per square foot. At 6 inches, about 0.028 tons. The math: depth in feet times area gives cubic feet, divide by 27 for cubic yards, multiply by 1.4 tons per yard for crushed stone.
What is the cheapest gravel for a driveway?
Locally quarried crusher run (also called crush and run or ABC) is usually cheapest per ton and packs hard, which is why it is the standard base and often the whole driveway in rural builds. Decorative stone like pea gravel costs more and migrates underfoot.
Do I really need multiple layers?
For a driveway that lasts, yes. Big stone (#3) at the bottom locks into the soil, crusher run or #57 in the middle, and crushed stone with fines on top packs into a surface. Skipping layers is why gravel driveways develop ruts and swallow stone every year.
Why do gravel prices vary so much by location?
Stone is heavy and cheap, so trucking dominates the price. The same ton that costs $18 at a quarry can cost $45 delivered 30 miles away. Always price from the two or three nearest quarries, not national averages.
