How the gravel calculation works
Cubic feet = length × width × depth in feet
A 50 × 10 ft driveway at 4 in deep is 50 × 10 × 0.333 = 166.7 cu ft.
Divide by 27 for cubic yards, then add compaction
166.7 ÷ 27 = 6.17 yd³. With 10% extra for compaction it is 6.79 yd³.
Multiply yards by the weight to get tons
Gravel typically weighs about 1.4 tons per yard, so 6.79 yd³ is about 9.51 tons. Ask your supplier for their figure.
Add labor and your markup
Spreading and grading hours × your hourly cost, plus markup on the total cost, gives the price to quote.
Worked example. A 50 × 10 ft driveway topped with 4 in of gravel and 10% for compaction needs 6.79 yd³, about 9.51 tons at 1.4 tons per yard. At $45 a ton the gravel costs $427.78. With 6 labor hours at $55 ($330) and a 25% markup ($189.44), the job price is $947.22.
Gravel FAQ
How much gravel do I need for a driveway?
Multiply length × width × depth in feet and divide by 27 for cubic yards. A 50 × 10 ft driveway at 4 in needs about 6.2 yd³, or 6.8 yd³ with 10% for compaction.
How many tons of gravel do I need for a 100 ft driveway?
For a 100 × 12 ft driveway with a 4 in top layer: 400 cu ft ÷ 27 = 14.81 yd³, or 16.30 yd³ with 10% for compaction. At 1.4 tons per yard that is about 22.8 tons. A 6–8 in base layer for a new driveway needs 1.5 to 2 times as much again.
How many tons are in a yard of gravel?
Typically 1.3–1.5 tons, depending on the stone and moisture. This calculator uses 1.4 as a starting point; your supplier can give the exact figure.
How much does a yard of pea gravel cover?
One cubic yard covers about 162 sq ft at 2 in deep, 108 sq ft at 3 in and 81 sq ft at 4 in.
How deep should a gravel driveway be?
A new driveway usually has 4–8 in of larger base stone with 2–4 in of smaller top gravel. Resurfacing an existing driveway often needs only 2–3 in.
How do I price a gravel job?
Add the gravel cost, delivery, crew and machine hours at your full hourly cost, then add your markup. A 25% markup on cost is a 20% margin on the price.
