Gravel Calculator

To estimate gravel, enter the finished area and compacted depth, choose a maintainable type/density preset, then edit waste, compaction, supplier minimum, and delivery. The tool returns cubic yards, tons, material cost, delivered total, and a matching shopping list.

Plan quantity and delivered cost with editable US defaults. This is an estimate, not a supplier quote.

Price basis: June 2026

1. Material and dimensions
2. Ordering assumptions

Formula: compacted yd³ × (1 + waste) × (1 + compaction) × density = tons to order. A supplier minimum affects cost, not the physical quantity needed.

Assumptions

  • 1.4 tons/yd³ density
  • 5% waste allowance
  • 10% compaction allowance
  • $30 per ton
  • $125 delivery
  • 5-ton supplier minimum
  • 0.5 ft³ bags at $5.5 each for comparison
  • US national planning defaults researched June 2026. Edit density and prices to match your supplier; tax is excluded.

Estimate only — confirm availability, load minimums, tax, quantities, and price with your supplier before buying.

How to calculate gravel

The formula: tons = area × depth ÷ 324 × (1 + waste) × (1 + compaction) × density; billable tons = max(order tons, supplier minimum)

  1. Measure length and width in feet and the finished, compacted depth in inches.
  2. Choose a gravel type. Its density preset converts volume to weight, and both density and price stay editable.
  3. Add separate waste and compaction allowances. They increase the loose amount ordered without changing the finished dimensions.
  4. Enter your supplier's price, delivery fee, and minimum load; the minimum affects billable cost, not the physical quantity needed.
  5. Copy or print the shopping list, then confirm density, load minimum, tax, and availability with the supplier.

Prices shown are national averages (as of 2026-06) and vary by region, brand, and supplier. They are estimates, not quotes.

Gravel weight, coverage & conversions

Gravel is sold by the ton but measured by volume, so the conversion is where people get stuck. Typical gravel weighs about 1.4 tons (≈2,800 lbs) per cubic yard. To convert cubic yards to tons, multiply by 1.4; to convert tons to cubic yards, divide by 1.4 (1 ton ≈ 0.71 cubic yards). The tables below cover weight, how much area a ton or yard covers at common depths, and the weight and price of each gravel type.

Cubic yards → tons (≈1.4 tons/yd³)

Cubic yardsWeight (tons)Weight (lbs)
1 yd³1.4 tons2,800 lbs
2 yd³2.8 tons5,600 lbs
3 yd³4.2 tons8,400 lbs
5 yd³7.0 tons14,000 lbs
10 yd³14 tons28,000 lbs

Tons to cubic yards: divide tons by 1.4 (1 ton ≈ 0.71 yd³). Dense crushed run runs closer to 1.5 tons/yd³.

Coverage — area per ton and per cubic yard

Depth1 ton covers1 cubic yard covers
2 in~115 sq ft~160 sq ft
3 in~80 sq ft~108 sq ft
4 in~60 sq ft~81 sq ft
6 in~40 sq ft~54 sq ft

Loose gravel before compaction, based on ~1.4 tons per cubic yard. Driveways are usually 4 in, often in two layers.

Gravel type — weight & bulk price (before delivery)

TypeWeight / yd³Price / ton
Pea gravel~1.4 tons$30 – $55
Crushed stone #57 (3/4 in)~1.4 tons$20 – $40
Crushed run / road base~1.5 tons$15 – $30
Crushed limestone~1.4 tons$20 – $40
River rock (decorative)~1.4 tons$45 – $130

Bulk per-yard price is roughly 1.4× the per-ton price. Delivery is a flat fee, so the per-ton cost drops on larger loads. Prices are 2026 national averages — estimates, not quotes.

How much does gravel cost?

Gravel costs roughly $25–$65 per ton, or about $15–$45 per cubic yard, for common landscape and driveway stone before delivery. Delivered, expect $40–$90 per ton including a flat delivery fee. For a 20×10 driveway at 3 inches deep (about 2.6 tons), that is roughly $150–$400 delivered. Spreading and grading by a pro adds labor on top.

What drives the cost

DIY vs. hiring a pro

Gravel is one of the most DIY-friendly materials — order a delivery, then rake and spread it yourself. The cost is the stone and delivery, not labor, so spreading it yourself saves the most on small jobs. For a long driveway or one needing grading and compaction, a contractor with a skid steer is faster and flatter; get a couple of quotes.

Installed and labor figures are national-average ranges, not quotes — get a few local estimates for your project.

Gravel FAQ

How many tons of gravel do I need for a driveway?+

A 20 ft × 10 ft area at 3 inches compacted depth is about 1.85 cubic yards before allowances, or roughly 2.6 tons at 1.4 tons/yd³. Waste and compaction allowances increase the order quantity; a supplier minimum can increase the billable quantity again.

How deep should gravel be?+

2–3 inches for walkways and beds, and 4 inches (often in two layers) for a gravel driveway.

How much does a yard of gravel weigh?+

About 1.4 tons — roughly 2,800 lbs — for typical dry gravel. Dense crushed run or wet gravel weighs a bit more, around 1.5 tons (3,000 lbs) per cubic yard.

How do I convert cubic yards of gravel to tons?+

Multiply cubic yards by 1.4. So 3 cubic yards is about 4.2 tons. To go the other way, divide tons by 1.4 — 1 ton is roughly 0.71 cubic yards.

How much area does a ton of gravel cover?+

About 100–115 sq ft at 2 inches deep, ~80 sq ft at 3 inches, and ~60 sq ft at 4 inches. A full cubic yard covers about 108 sq ft at 3 inches deep.

How much does a ton of gravel cost?+

Bulk gravel runs about $20–$55 per ton for common crushed stone and pea gravel before delivery. Crushed run / road base is cheapest ($15–$30 per ton); decorative river rock is the most ($45–$130). Delivery adds a flat fee, so the per-ton price drops on larger loads.

How much does gravel cost for a driveway?+

A 20×10 driveway at 3 inches deep needs about 2.6 tons. At $40–$90 per ton delivered, that is roughly $150–$400 in gravel, before any grading labor.

Is it cheaper to buy gravel by the ton or yard?+

Bulk by the ton or cubic yard is far cheaper than bagged gravel for any real area. Bags only make sense for small touch-ups.
