Readymix Calculator
Readymix Calculator
When starting a concrete project — whether it’s a driveway, foundation, patio, or floor slab — the biggest challenge is knowing how much ready-mix concrete to order. Ordering too little causes delays and inconsistencies, while ordering too much leads to waste and unnecessary cost.
The Readymix Calculator eliminates this guesswork by instantly calculating the exact volume of ready-mix concrete required for your project. All you need are your project dimensions — length, width, and depth — and the calculator will tell you how much ready-mix concrete to order in cubic meters, cubic feet, or cubic yards.
This calculator is perfect for builders, contractors, DIYers, and homeowners who want accurate, fast, and reliable results.
How to Use the Readymix Calculator
Follow these simple steps to calculate your concrete volume instantly:
- Choose the Shape of Your Project
Select whether your concrete area is rectangular, cylindrical, or custom-shaped. - Enter Project Dimensions
- For rectangular areas, input length, width, and depth.
- For cylindrical areas (like columns), input diameter and height.
You can use either feet/inches or meters/centimeters.
- Select Measurement Unit
Choose to view your results in cubic yards, cubic meters, or cubic feet — depending on your location or supplier. - Click “Calculate”
Instantly see:- Total concrete volume needed.
- Ready-mix load size recommendation (in cubic yards or cubic meters).
- Number of truckloads required for large pours.
- Adjust for Waste (Optional)
Add 5–10% extra volume to account for spillage, leveling, and surface variation.
Example Calculation
Let’s say you’re pouring a garage floor measuring 22 feet long, 18 feet wide, and 4 inches thick.
- Convert 4 inches to feet → 4 ÷ 12 = 0.333 ft
- Multiply: 22 × 18 × 0.333 = 131.9 cubic feet
- Convert cubic feet to cubic yards → 131.9 ÷ 27 = 4.89 cubic yards
✅ You’ll need approximately 5 cubic yards of ready-mix concrete for your garage floor.
Most ready-mix trucks carry between 8–10 cubic yards, so one truck will easily handle this pour.

Understanding Readymix Concrete
Ready-mix concrete is a pre-measured, pre-mixed product that’s delivered straight from a batching plant in a concrete truck. It ensures consistent quality, saves mixing time, and allows for large pours with minimal labor.
Readymix concrete is commonly used for:
- Driveways and Walkways
- Patios and Deck Bases
- Foundations and Slabs
- Footings and Columns
- Commercial Flooring Projects
Using the Readymix Calculator ensures you order the correct quantity — saving both time and money while maintaining quality and uniformity in your project.
Tips for Accurate Concrete Calculation
- Always measure the area in one unit system (either all metric or all imperial).
- Add 5–10% extra for leveling, uneven ground, or waste.
- Use a depth gauge or string line for accurate measurements.
- Double-check truck capacity before ordering large amounts.
- Order slightly more if you’re pouring in hot or dry weather (due to evaporation).
Recommended Concrete Depths by Project Type
| Project Type | Recommended Depth |
|---|---|
| Sidewalk or Path | 4 inches (10 cm) |
| Patio or Driveway | 4–6 inches (10–15 cm) |
| Garage Floor | 4–5 inches (10–13 cm) |
| Foundation Footing | 8–12 inches (20–30 cm) |
| Concrete Slab | 4 inches (10 cm) minimum |
Use these standard depths when inputting your dimensions into the calculator for more accurate estimates.
Advantages of Using Ready-Mix Concrete
- ✅ Consistent Quality: Mixed in controlled environments.
- 🕒 Time-Saving: No need for on-site mixing.
- 💪 High Strength: Ideal for both residential and commercial applications.
- 🚚 Delivered Fresh: Straight from the batching plant to your site.
- ♻️ Less Waste: You only order what you actually need.
By combining accuracy with convenience, ready-mix concrete has become the go-to choice for most modern construction projects.
