Driveway Cost Estimator
Choose a driveway material, enter the driveway size and your local prices, and this estimator works out how much material to order, what it costs, and the total including any labour and site preparation you add. Run it once per material to compare options side by side.
Enter your measurements
Enter your measurements and press Calculate to see quantities, a material breakdown and an optional cost estimate.
How the calculation works
- Concrete: Volume = Area × Thickness × (1 + Waste %); Cost = Volume × Price per yd³
- Asphalt or gravel: Weight = Volume × Density; Cost = Weight × Price per ton
- Pavers: Cost = Area × (1 + Waste %) × Price per ft²
- Total = Material + (Area × Labour price) + Other costs
Each material is priced the way suppliers usually sell it: concrete by volume, asphalt and gravel by weight, and pavers by area.
Asphalt and gravel densities are editable starting values. Use your supplier's figure when you have it.
Assumptions used
- Thickness is the finished depth of the surface layer. A compacted gravel base is usually needed underneath and is not included unless you add it as another cost.
- Labour, removal of an old driveway, permits and drainage vary widely and are included only if you enter them.
Example calculation
A 50 × 12 ft gravel driveway, 4 in deep, 5% waste, gravel at 1.4 tons/yd³ and $40 per ton.
- 1Area: 50 × 12 = 600 ft²
- 2Volume: 600 × (4 ÷ 12) × 1.05 = 210 ft³ = 7.78 yd³
- 3Weight: 7.78 × 1.4 = 10.89 tons
- 4Cost: 10.89 × $40 = $435.56, or $0.73 per ft²
Result: About 10.9 tons of gravel costing roughly $436 before delivery and labour.
How to measure your project
- Measure the full length from the garage or parking pad to the street, plus any turning or parking areas.
- Measure width at several points. Driveways often flare at the street.
- For curved driveways, measure along the centre line for length and use the average width.
Frequently asked questions
Which driveway material is cheapest?
Gravel usually has the lowest upfront cost, followed by asphalt, then concrete and pavers. Long-term maintenance, climate and local prices change the picture, so run the estimator with quotes for each material you are considering.
How thick should a driveway be?
Common ranges are 4–6 in (10–15 cm) of concrete, 2–3 in (5–8 cm) of compacted asphalt over a base, and 4–8 in (10–20 cm) of gravel. Heavier vehicles and soft soils need more. Follow local practice and your contractor's advice.
Does the estimate include the base layer?
No. Most driveways need compacted crushed stone underneath. Size it with the driveway gravel calculator or paver base calculator, then add its cost under other costs.
