How to estimate the cost of concrete
The cost of concrete is the amount you order times the price. Calculate cubic yards for your area, add 5 to 10 percent for waste, then multiply by the delivered price per cubic yard. If your supplier sells concrete by the ton, multiply the tons by the price per ton instead. One cubic yard of concrete weighs about 2.02 US tons as a planning value.
Worked example
A 20 by 10 foot area at 4 inches deep needs 2.47 cubic yards, or 2.72 cubic yards with 10 percent extra. At the sample price of $150 per yard, the material is $407.41. Add delivery and tax for your total.
Concrete cost at different prices
The table shows the material cost of the example order at several prices per cubic yard. Find the price closest to your quote.
| Price per cubic yard | Material cost | Per US ton |
|---|---|---|
| $90 | $244.44 | $44.44 |
| $120 | $325.93 | $59.26 |
| $150 | $407.41 | $74.07 |
| $190 | $516.05 | $93.83 |
| $225 | $611.11 | $111.11 |
| $300 | $814.81 | $148.15 |
Ways to lower the cost of concrete
- Get delivered quotes from at least two suppliers.
- Order one larger load instead of several small ones to avoid repeated delivery fees.
- Measure carefully so you order the right amount with a small allowance.
- Ask whether there is a price break at a larger quantity.
These figures are planning estimates. Real material varies in moisture, size, and compaction, so confirm weights and order quantities with your supplier.
Frequently asked questions
How much does a yard of concrete cost?
It depends on your area and supplier. Ask for a delivered price, then use the estimator.
How do I convert a price per ton to a price per yard for concrete?
Multiply the price per ton by 2.02, the tons in one cubic yard.
Is delivery included?
Not unless your supplier says so. Add it in the delivery field.
How much concrete do I need?
Use the calculator above. A 20 by 10 foot area at 4 inches needs about 2.47 cubic yards.
