Patio Cost Calculator
Use this free patio cost calculator to estimate what a new patio will cost before you order materials or call a contractor. Enter the length and width, pick a material, choose a finish and edging, and say whether you will hire the work out or do it yourself. The calculator works out the area, adds a waste allowance for cuts, and gives you a total cost with a per-square-foot breakdown.
10% is standard for pavers and brick, to cover cuts, breakage, and pattern matching. Use 5% for a plain rectangle of stamped concrete.
| Amount | Value |
|---|---|
| Patio area | 192 sq ft |
| Perimeter (edging length) | 56 ft |
| Material cost | $1,728 |
| Waste allowance (10%) | $173 |
| Finish (sealed) | $288 |
| Labor | $1,536 |
| Edging | $448 |
| Total cost | $4,173 |
| Cost per square foot | $21.73 |
How it works
A patio price is built from five pieces, and this calculator adds them in order so you can see where the money goes. First comes the area: length times width in feet gives square feet, so a 12 by 16 foot patio is 192 square feet. Everything else is priced per square foot or per linear foot, so the area is the number that drives the whole estimate.
Second is the material. The calculator uses typical material-only prices: gravel at $3 per square foot, stamped concrete at $8, concrete pavers at $9, brick at $11, and natural stone at $16. These are material prices, not installed prices, which is why the labor choice is separate. A waste allowance, 10 percent by default, is added on top of the material cost to cover pavers cut to fit the edges, pieces that break, and pattern matching. On a plain rectangular patio you can drop this to 5 percent; on a curved patio or a herringbone pattern, keep it at 10 to 15 percent.
Material cost = area × material price × (1 + waste %)
Finish cost = area × finish price
Labor cost = area × labor rate ($8 professional, $0 do it yourself)
Edging cost = perimeter × $8 per linear ft
Total cost = material + finish + labor + edging
Third is the finish. A standard unsealed patio adds nothing. Sealing adds $1.50 per square foot and is the usual choice for pavers, brick, and stamped concrete: it deepens the color, resists stains, and slows weeds between the joints. A premium textured finish, such as a tumbled or antiqued paver, adds $3 per square foot. Fourth is labor: professional installation at $8 per square foot, or zero if you do the work yourself. That labor figure covers excavation, the compacted base, laying, and cleanup, but not demolition of an old patio or hauling soil away.
Fifth is edging, priced at $8 per linear foot around the full perimeter, which is twice the length plus twice the width. Edging is not decoration: it is the restraint that stops pavers and brick from creeping outward under foot traffic. A gravel patio needs edging too, or the gravel wanders onto the lawn within a season. Divide the total by the area to get the cost per square foot, the figure most useful for comparing quotes from different contractors.
Remember that this is a planning estimate. Prices vary with your region, the season, and access to the site: a patio behind a house with no side access costs more to build than one beside a driveway, because every wheelbarrow of base material has to travel further. Get two or three written quotes and compare them against this estimate line by line.
Worked example
You want a 12 foot by 16 foot patio of concrete pavers, sealed, with edging, built by a professional.
Step 1: Find the area — 12 × 16 = 192 square feet.
Step 2: Find the perimeter — 2 × (12 + 16) = 56 linear feet of edging.
Step 3: Material cost — 192 × $9.00 = $1,728, plus 10% waste, $172.80, giving $1,900.80.
Step 4: Finish — 192 × $1.50 = $288 for sealing.
Step 5: Labor — 192 × $8.00 = $1,536 for professional installation.
Step 6: Edging — 56 × $8.00 = $448.
Step 7: Add it up — $1,900.80 + $288 + $1,536 + $448 = $4,172.80, or $4,173 rounded.
The result is a total cost of $4,173, which is $21.73 per square foot for a 192 square foot patio. The same patio built yourself would cost $2,637, because the $1,536 of labor drops out.
FAQ
How much does a patio cost per square foot?
A professionally installed patio usually costs about $14 to $36 per square foot, depending on the material. Gravel is the cheapest at roughly $6 to $10 per square foot installed, stamped concrete runs about $16 to $20, concrete pavers about $17 to $25, brick about $19 to $28, and natural stone about $24 to $36. Doing the work yourself removes the labor charge, which is roughly $8 per square foot, but you still pay for materials, base gravel, sand, and edging.
What is the cheapest patio material?
Gravel is the cheapest patio material by a wide margin, at about $3 per square foot for materials alone. It is easy to install yourself, drains well, and suits a casual seating area. Its drawbacks are that chairs wobble on it, it migrates onto the lawn, and it needs topping up every year or two. Concrete pavers are the best value for a patio you will use every day, because they look good, can be lifted and reset if one settles, and last for decades.
How do I measure my patio area?
Measure the length and width of the patio in feet with a tape measure, then multiply them to get square feet. A patio that is 12 feet long and 16 feet wide is 192 square feet. For a curved or irregular patio, measure it as a series of rectangles, work out each rectangle separately, and add them together. Always add about 10 percent extra material for cuts, breakage, and pattern matching, which this calculator does for you.
Is sealing a patio worth the extra cost?
Sealing is worth it for pavers, brick, and stamped concrete in most cases. A sealer, at about $1.50 per square foot, deepens the color, keeps stains from soaking in, and slows weed growth between pavers. It needs reapplying every two to three years. Skip the sealer on a gravel patio, where it serves no purpose, and on a patio that will be covered by a roof, where rain and sun cause less wear.
Should I build my patio myself or hire a professional?
A small, flat gravel or paver patio is a realistic weekend project if you are comfortable digging, leveling, and compacting a base. You save roughly $8 per square foot in labor. Hire a professional for patios over about 300 square feet, for any site that slopes, for natural stone, which is heavy and hard to cut, and for stamped concrete, which needs skill and timing. A badly laid base is the most common cause of a patio that sinks or tilts, and fixing it costs more than hiring help in the first place.
