Stamped Concrete Cost Calculator
A stamped concrete cost calculator adds concrete by the yard to labor per sq ft: a 12 × 12 ft patio at 4 in with $12 labor comes to $1,994.67.
Stamped concrete cost calculator formula
A stamped concrete cost calculator adds two parts. The formula is total cost = (cubic yards of concrete × price per yard) + (area in square feet × labor rate).
The cubic yards come from length × width × (depth in inches ÷ 12) ÷ 27. The default price is $150 per cubic yard of concrete, and the default labor is $12 per square foot for the forming, pouring, coloring, stamping and sealing. Both are placeholders to replace with local quotes.
Unlike some of the calculators on this site, this one does not add a waste percentage. Add your own allowance to the concrete price or the depth if you want one.
Worked examples
Example 1 is the default patio, 12 ft × 12 ft and 4 inches thick.
- Area: 12 × 12 = 144 sq ft
- Concrete: 144 × (4 ÷ 12) ÷ 27 = 1.78 cubic yards
- Concrete cost: 1.7778 × $150 = $266.67
- Labor: 144 × $12 = $1,728.00
- Total: $1,994.67
Example 2 is a larger patio, 20 ft × 15 ft at 4 inches, with concrete at $160 per yard and labor at $14.
- Area: 20 × 15 = 300 sq ft
- Concrete: 300 × (4 ÷ 12) ÷ 27 = 3.70 cubic yards
- Concrete cost: 3.7037 × $160 = $592.59
- Labor: 300 × $14 = $4,200.00
- Total: $4,792.59
In both jobs, labor is most of the bill. Concrete is about 13 percent of the first total and 12 percent of the second.
Where the money goes
| Cost item | Where to enter it |
|---|---|
| Ready-mix concrete | Price per cubic yard |
| Delivery or short-load fees | Add to the price per yard |
| Forming, pouring and finishing | Labor rate |
| Integral color or color hardener | Labor rate or concrete price |
| Release agent | Labor rate |
| Stamping mats and tools | Labor rate |
| Sealer | Labor rate |
| Base preparation | Usually separate |
| Reinforcement | Often separate |
Ask your contractor what their square-foot price includes. Stamped concrete is a per-square-foot trade, so a number that covers the base and the reinforcement makes comparisons easy.
Thickness and joints
Patios are commonly poured 4 inches thick, and areas for vehicles are thicker. Your local code, the soil and the base set the real requirement, so check them before you pick a depth. Stamped surfaces still need control joints to guide cracking, and a good installer will lay them out so they follow the pattern. Some cracking is normal in concrete, and control joints let you choose where it happens.
Use the concrete patio calculator when you want to order the concrete itself.
How to measure
- Measure the length and width of the area to be poured, including steps and landings.
- For curved edges, divide the area into shapes and add them together.
- Measure the slab thickness at the form. A depth of 4 inches means 4 inches after the base is compacted.
- Take notes about access. A pump truck or wheelbarrow work changes the labor.
Common mistakes
- Comparing a stamped quote with a plain broom-finish quote without checking what each covers.
- Leaving out the base and the reinforcement. They are not in the calculator.
- Ordering the exact volume. Real pours use more concrete than a measured slab, because of uneven subgrade and spillage. Your supplier can advise on a margin.
- Ignoring weather. Heat and wind shorten the working time for stamping.
- Skipping sealer or using the wrong one. Follow the stamp-color and sealer manufacturers’ instructions.

Frequently asked questions
Why does stamped concrete cost so much more than a plain patio?
The concrete itself costs the same. The extra is labor and materials for the decorative work: color, release agent, stamping mats, a crew fast enough to stamp before the surface sets, and sealer. In this calculator that is the labor rate per square foot, set at $12 by default.
Is the color and sealer cost included in the labor rate?
The calculator has two lines only: concrete by the cubic yard and labor by the square foot. Put color, release agent and sealer into whichever you prefer. Many contractors fold them into a per-square-foot price, so ask a contractor for a number that covers them.
How often does stamped concrete need resealing?
Sealer wears with traffic and weather. Many sealer makers suggest resealing every few years, but it depends on the product and the use. Follow the instructions on the sealer you use, and ask your installer what they put down.
What patterns are available and does the pattern change the price?
Common patterns imitate brick, slate, flagstone, cobblestone and wood plank. Simple repeating patterns take less time than ones with many colors and borders, so the labor rate can differ. Ask for prices on the exact pattern, since the calculator uses one flat rate.
How does this compare to the plain Concrete Patio Cost Calculator?
The math is the same: concrete volume times a price, plus labor. Stamping raises the labor rate. Run both with their own rates and compare the totals. A plain broom-finished patio can use a much lower labor rate than the stamped one in this calculator.
