Permeability ratings, water flow calculations, and French drain specifications for proper drainage design.
Adjustable 10-25% compaction settings based on usage, traffic, and material type for accurate quantities.
Automatic conversion to tons, pounds, and kilograms for delivery planning and vehicle capacity.
Detailed pricing for materials, delivery, landscape fabric, and equipment rental with budget recommendations.
Specialized modes for driveways, pathways, French drains, concrete base, playgrounds, and erosion control.
Gravel volume calculation involves three key measurements: area, depth, and compaction factor. The basic formula is:
Cubic Yards = (Area in sq ft × Depth in inches) ÷ 324
Example: For a 12 ft × 50 ft driveway with 4 inches of gravel:
(600 × 4) ÷ 324 = 7.4 cubic yards
Add 15% compaction: 7.4 × 1.15 = 8.5 cubic yards (round to 9 yards for ordering)
Pro Tip: Deeper layers provide better stability, drainage, and longevity but increase material costs.
Why Compaction Matters:
Gravel compacts 10-20% after installation due to vibration, traffic, and gravity. This settling reduces the effective depth and coverage area. Always order extra material to account for compaction.
Compaction Factors by Application:
Gravel is sold by weight (tons) or volume (cubic yards). Conversion depends on material density:
Example: 10 cubic yards of crushed stone = 10 × 1.4 = 14 tons
| Gravel Type | Size | Weight/CY | Best For | Pros | Cons |
|---|---|---|---|---|---|
| Crushed Stone | ¾ inch | 1.4 tons | Driveways, base layers | Excellent compaction, drainage, stability | Sharp edges, dusty |
| Pea Gravel | ¼-½ inch | 1.3 tons | Pathways, landscaping | Smooth, decorative, comfortable to walk on | Shifts easily, poor for driveways |
| River Rock | 1-3 inches | 1.2 tons | Decorative landscaping, drainage | Attractive, smooth, natural look | Expensive, poor compaction |
| Limestone | ½-1 inch | 1.35 tons | Driveways, pathways | Affordable, good compaction, bright color | Dusty, alkaline (affects plants) |
| Granite | ¾-1 inch | 1.4 tons | High-end landscaping, driveways | Very durable, attractive, various colors | Expensive, heavy |
| Marble Chips | ½-¾ inch | 1.35 tons | Decorative beds, pathways | Elegant, bright white, reflects light | Very expensive, stains easily |
| Lava Rock | ½-2 inches | 0.8 tons | Landscaping, fire pits | Lightweight, porous, unique color | Expensive, sharp, absorbs heat |
| Decomposed Granite | ¼ inch | 1.3 tons | Pathways, patios | Natural look, compacts well, permeable | Erodes over time, needs edging |

Pea Gravel: ₹1,000-1,500 per ton, ₹2,500-3,000 per cubic yard
River Rock: ₹1,200-1,800 per ton, ₹3,000-3,500 per cubic yard
Limestone: ₹700-1,000 per ton, ₹1,800-2,200 per cubic yard
Granite: ₹1,500-2,000 per ton, ₹3,500-4,000 per cubic yard
Marble Chips: ₹2,000-3,000 per ton, ₹4,500-5,500 per cubic yard
Delivery Charges: ₹2,000-4,000 (varies by distance and quantity)
Landscape Fabric: ₹50-100 per square meter
Edging Materials: ₹200-500 per linear meter
Labor (DIY vs Pro): ₹100-200 per sq ft installed
Equipment Rental: Plate compactor ₹1,500-2,500/day
Excavation: ₹50-100 per cubic yard if needed
Budget Example: 12 ft × 50 ft Driveway (600 sq ft)
To calculate gravel needed: 1) Measure area length and width, 2) Calculate area (length × width), 3) Choose desired depth (2-4 inches typical for driveways), 4) Convert to cubic yards (area × depth ÷ 324), 5) Add 10-15% compaction factor. Our calculator does this automatically for any shape and gravel type.
For a standard 12 ft × 50 ft driveway at 4 inches depth, you need approximately 7.5 cubic yards of gravel. Formula: (12 × 50 × 4) ÷ 324 = 7.4 cubic yards. Add 15% for compaction = 8.5 cubic yards. Our calculator provides exact quantities with compaction factors included.
Conversion depends on gravel type: Crushed stone 1.4 tons/cubic yard, Pea gravel 1.3 tons/cubic yard, River rock 1.2 tons/cubic yard, Limestone 1.35 tons/cubic yard. For 10 cubic yards of crushed stone: 10 × 1.4 = 14 tons. Our calculator shows both cubic yards and tons automatically.
