The calculator above will estimate amount of concrete needed to pour solid concrete stairs in Cubic Feet, Cubic Yards and 80 lb. bags, as well as cost of concrete mix, using latest prices from big home improvement stores, such as Home Depot, Lowe’s, etc.

NOTE: It is important to keep in mind, that when providing number of STEPS, do not count final step or “platform”. Otherwise you will get incorrect calculation. See included diagram. Using the diagram as example, you would need to enter “step count” of 3.

Lastly, we recommend that you get 5-10% more concrete mix, that is estimated, as our calculator provides EXACT measurements, and does not account for waste!

Average cost of concrete

Across the US, homeowners report that ready – mix concrete costs about $98-99 per cubic yard.
The average cost of a concrete slab (6 inches thick) is $5.00-5.50 per square foot, including materials and labor. However, the price can go up to $9-10 per square foot depending on numerous factors and enhancement costs.

Thus, your cost to pave a 2-car driveway of 16 feet wide, and 40 feet long (640 sq.ft.) will be about $3,200 – 3,520.

Keep in mind that you total project cost can increase depending on the following:

– local concrete prices
– type of concrete and finish you want
– edge thickness: thicker edges cost $1-2 per square foot extra
– cost of reinforcement. Fibermash is standard. Installing wiremash adds $0.35 per sq.ft. to total cost
– adding a vapor barrier: $0.5-0.6 per square foot
– 2″ styrofoam under the slab (this is required by building code in some states): $2 per square foot extra
– grading
– preparing the sub-base
– removing shrubs, stones, trees, etc: add $0.5-1.55 per square foot
– optional radiant flooring installation: $6-8 per square foot extra

Pricing for popular stamped concrete projects: patio, driveway, pool deck

Cost of Stamped Concrete Patio

Many homeowners that want a concrete driveway, walkway, patio or pool deck, choose to go for stamped concrete, which looks much better than the plain grey color mixture.

Costs for stamped concrete vary greatly; starting at around $8 per square foot, all the way up to $20+ per square foot. Most homeowners pay a mid-range price of $10-12 per square foot.

Thus, to pave a 640 sq.ft. driveway with stamped concrete will cost $5,120 – $7,680. An average size 15×20 stamped concrete patio (300 sq.ft.) costs $2,400-3,600. A typical size pool deck of 800 sq.ft. will cost $8,500 – 12,000. Because there is constant exposure to water, your concrete deck will need to be sealed multiple times with special moisture-resistant sealant. A walkway of (100 sq.ft.) made with decorative concrete will run $1,000-2,500.

Your final price will depend on the colors, patterns, and overall complexity of design you want to have.

Plain one stamp pattern with one color: $8.5-13 per square foot.

Contrasting patterns, borders, texture, 2-3 colors: $13 – 18 per square foot.

Multiple patterns, hand-stained colors, advanced stenciling, borders, special designs. This type of decorative concrete realistically replicates the look of stone: – $20 per square foot and up.

Why use decorative concrete pavement?

By using stamps, its possible to recreate the look of such premium materials as brick, ashler stone, paving stone, slate, cobblestone, limestone, weathered wood etc. at only a fraction of the cost ( up to 50% less).

To compare, brick pavement costs $15-20 per square foot. Pavement made of cobble stone, slate, or marble costs $17-28 per square foot.

Another huge benefit is that concrete pavement requires minimal maintenance compared to other materials.

To achieve a custom look, contractors use various types of colors such as stains and powered pigments, and combine them with an array of patterns and textures. Only your imagination is the limit to the type of design that can be achieved with concrete. Many homeowners add unique stencils such as leaves, trees, flowers, animals, symbols, etc. If you are not sure what you would like, a professional concrete installer will have a portfolio of at least 40-50 patterns and 50-60 colors to choose from.

One way to save money on this project is to use plain concrete for the large portion of the driveway, patio or deck, and use stamped concrete for accents and borders.

If you already have a concrete driveway and or another area, its possible to enhance the way it looks by adding a decorative concrete overlay on top. The average cost of this overlay starts at $3-5 per square foot, but can go up to as much as $12-15 per square foot depending on the complexity of colors and patterns you want.

Keep in mind that applying a decorative concrete overlay is only recommended if your existing concrete pavement is in good condition, without major cracks and dents.

    Your concrete calculator is slightly off. 8 foot by 10 foot by 4 inches should be exactly 1 yard. Your calc has it at .98765 yards. This will cause customers to under order especially on large projects where they will need 8 or more yards.

      Tony, you are wrong. Cubic yard is 27 cubic feet. Per your example, 8′ x10 ‘ x 4″ = 80’ / 3 = 26.6666667 cubic feet.

      Divide 26.6666667 by 27, you get 0.987654322 cubic yard… which is exactly the number you get from calculator.

      Sure you should round that up, and probably get some extra to account for waste, etc… but as far as MATH is concerned, our calculator is correct!
