Whether you're building a driveway, patio base, or road foundation, estimating the right amount of aggregate and total cost is essential. The Aggregate Cost Calculator helps you quickly determine the Volume of aggregate needed and the Total Estimated Cost based on your project’s dimensions and the price per ton.

Calculate aggregate cost step by step

Step 1: Calculate Volume in Cubic Feet

To calculate the volume of aggregate required, multiply the area (length × width) by the depth (converted to feet):

Formula:

Volume (ft³)=Length (ft)×Width (ft)×(Height (in)12)\text{Volume (ft³)} = \text{Length (ft)} \times \text{Width (ft)} \times \left( \frac{\text{Height (in)}}{12} \right)Volume (ft³)=Length (ft)×Width (ft)×(12Height (in)​)

Step 2: Convert Cubic Feet to Cubic Yards

Since aggregates are commonly sold in cubic yards:

Volume (yd³)=Volume (ft³)27\text{Volume (yd³)} = \frac{\text{Volume (ft³)}}{27}Volume (yd³)=27Volume (ft³)​

Step 3: Estimate the Cost

To calculate the total cost, you need to estimate the weight based on the volume and average density. A common assumption is that 1 cubic yard of aggregate weighs around 1.4 tons.

Total Cost=Volume (yd³)×1.4×Price per ton \text{Total Cost} = \text{Volume (yd³)} \times 1.4 \times \text{Price per ton}Total Cost=Volume (yd³)×1.4×Price per ton

Example Calculation

Let’s say you have a space that is:

  • Length = 20 ft
  • Width = 10 ft
  • Height = 6 inches
  • Price per ton = $50

Step 1: Volume in Cubic Feet

Volume (ft³)=20×10×(612)=100\text{Volume (ft³)} = 20 \times 10 \times \left( \frac{6}{12} \right) = 100Volume (ft³)=20×10×(126​)=100

Step 2: Convert to Cubic Yards

Volume (yd³)=10027≈3.70\text{Volume (yd³)} = \frac{100}{27} \approx 3.70Volume (yd³)=27100​≈3.70

Step 3: Estimate Total Cost

Total Cost=3.70×1.4×50=259\text{Total Cost} = 3.70 \times 1.4 \times 50 = 259Total Cost=3.70×1.4×50=259

Final Result

  • Volume Needed: 3.70 yd³
  • Estimated Cost: $259
