Material & Cost Breakdown
| Metric | Value | Notes |
|---|---|---|
| Square footage | 720 sq ft | 24 ft × 30 ft |
| Thickness | 5 in | Standard for vehicle traffic |
| Concrete volume | 11.11 yd³ | Before waste |
| Order volume (10% waste) | 12.22 yd³ | Ready-mix ordering target |
| 80 lb bags needed | 550 bags | Including waste |
| 60 lb bags needed | 734 bags | Including waste |
| Ready-mix material cost | $1,589 – $2,017 | ~$130–$165 per yard delivered |
| Installed cost (broom) | $4,320 – $10,800 | $6–$15 per sq ft |
* Installed cost assumes a standard broom finish, easy site access, and a prepared sub-base. Decorative finishes, tear-out, poor soil, or pump-truck access will move the price higher.
24x30 Driveway Cost by Thickness
Thickness is the single biggest lever on how much concrete a 24x30 driveway needs. A 4-inch pour suits patios and light foot traffic; step up to 5–6 inches for driveways, garages, shops, and anything carrying vehicles or heavy equipment. Each extra inch adds concrete volume and a little labor.
| Thickness | Concrete (10% waste) | Installed cost | Typical use |
|---|---|---|---|
| 4 in | 9.78 yd³ | $4,320 – $10,800 | Patios, walkways, light foot traffic |
| 5 in (standard) | 12.22 yd³ | $4,320 – $10,800 | Driveways, standard garages |
| 6 in | 14.67 yd³ | $4,752 – $11,232 | Shops, RV pads, heavy equipment |
How We Calculated It
- Area: 24 ft × 30 ft = 720 sq ft
- Volume: 720 sq ft × (5 in ÷ 12) = 300.0 cu ft ÷ 27 = 11.11 yd³
- With 10% waste: 11.11 × 1.10 = 12.22 yd³
- Bags (80 lb): 12.22 × 27 ÷ 0.60 cu ft/bag ≈ 550 bags
FAQs
How much does a 24x30 concrete driveway cost?
A 24x30 (720 sq ft) concrete driveway costs roughly $4,320 to $10,800 installed with a broom finish in 2026. Decorative finishes, tear-out, and site prep can raise the price.
How many cubic yards for a 24x30 driveway?
At 5 inches thick, a 24x30 driveway needs about 11.11 cubic yards before waste and 12.22 yards after a 10% ordering allowance.
How many 80 lb bags for a 24x30 driveway?
You would need about 550 bags of 80 lb concrete (including 10% waste). Above roughly one cubic yard, ready-mix is usually cheaper and easier than bags.
How much does a 24x30 driveway cost at 6 inches thick?
A 6-inch 24x30 driveway needs about 14.67 cubic yards of concrete and typically runs $4,752 to $11,232 installed. The thicker pour adds concrete volume, so it costs more than the standard 5-inch slab but resists cracking under vehicles and heavy loads.
Planning Your 24x30 Pour
When preparing to pour a 24 ft × 30 ft concrete driveway, proper planning is essential to keep your project on budget. The dimensions directly determine the total square footage, which in turn dictates the amount of labor, forming materials, and finishing time required.
The thickness is equally important. While 5 inches is standard for this type of driveway, increasing the thickness by just one inch will significantly increase the total cubic yards of concrete needed. Always ensure your sub-base is properly compacted and leveled; an uneven base can lead to thick spots that consume more concrete than your initial estimate predicted. Lastly, ordering with a 10% waste margin is a standard industry practice to account for minor spills, uneven ground, and the small amount of concrete left inside the delivery truck.
