Concrete Patio Cost Calculator

A concrete patio typically runs $6 to $20 per square foot installed, so a standard 300 sq ft broom-finish patio is about $2,400–$3,600, while a stamped or decorative patio of the same size can reach $4,500–$6,000. A basic 4-inch broom finish is at the low end ($6–$10/sq ft); colored, exposed aggregate, and stamped finishes run $11–$20. The drivers are the area, the finish (the biggest factor), the slab thickness, whether an old patio must be removed, and site prep like grading and a gravel base. Small patios carry a minimum charge because the fixed cost of forming and finishing doesn't shrink much. Enter your area, finish, thickness, and removal in the calculator to anchor the estimate.

A standard broom finish is the cheapest and most popular. After the concrete is poured and smoothed, a broom is dragged across the surface to create a fine texture that gives slip resistance — important for an outdoor surface that gets wet. It's economical (~$6–$10/sq ft installed), durable, and low-maintenance. Colored or stained concrete adds visual appeal for a bit more (~$11), exposed aggregate exposes decorative stone (~$13), and stamped concrete, which mimics stone, brick, or pavers, is the most expensive decorative option (~$16+). If budget is the priority, a broom finish — optionally with a single integral color for a low-cost upgrade — gives the best value, and you can still seal it for a richer look. The calculator prices all four finishes so you can compare.

Generally yes — a poured concrete patio usually installs cheaper than a paver patio of the same size. Plain or broom-finish concrete is the most economical option, while pavers cost more for the materials and the labor-intensive work of laying each unit on a prepared base. The gap narrows with decorative concrete, though: a stamped concrete patio can approach paver pricing. The trade-offs matter beyond price. Concrete is faster to install and low-maintenance but can crack over time and is hard to repair invisibly. Pavers cost more but individual units lift out and replace, and they flex with ground movement without cracking. Concrete suits budget-focused, low-maintenance projects; pavers suit those wanting a premium, easily-repairable look. The calculator estimates the concrete option, including stamped finishes if you want the paver look in concrete.

A standard concrete patio is poured 4 inches thick over a compacted gravel base, which handles foot traffic, furniture, and typical use. Upgrade to 5–6 inches with rebar or wire-mesh reinforcement where the patio will carry heavier loads — a hot tub (water alone is thousands of pounds), an outdoor kitchen, a fire feature, or any vehicle traffic. Thicker, reinforced slabs resist cracking and add longevity but cost more (the calculator adds about $1/sq ft for 5 inches and $2 for 6). Just as important as thickness, though, are a well-compacted base and properly placed control joints — those prevent cracks as much as the slab depth does. For a standard patio, 4 inches is the norm; upgrade the thickness only under the areas that will bear heavy features.

Some hairline cracking over time is normal — concrete shrinks as it cures and moves with temperature changes. The keys to keeping cracks minimal and cosmetic rather than structural are a well-compacted gravel base, proper slab thickness, adequate reinforcement (wire mesh or rebar), and correctly placed control joints. Control joints are the grooves cut or tooled into the slab that create planned weak lines, so the inevitable shrinkage cracking happens neatly along them instead of randomly across the surface. Good drainage and grading away from the house help, as does sealing. You can't guarantee a forever crack-free patio, but a quality install — solid base prep, the right joints, and reinforcement — keeps cracking to thin, controlled lines rather than the wide, wandering cracks of a poorly built slab. The calculator includes base-prep and rebar add-ons for exactly this.

Sealing isn't strictly required, but it's recommended — especially for colored, stamped, and exposed-aggregate patios. A quality sealer protects against stains (food, grease, leaves), moisture penetration, freeze-thaw scaling in cold climates, and UV fading of colored finishes, and it makes the patio easier to clean. Decorative finishes benefit most because the sealer enhances and preserves their color and pattern (stamped concrete looks noticeably richer sealed). Plain broom-finish patios can be left unsealed but still last longer with periodic sealing. Most sealers need reapplying every 2–3 years. It's a low-cost, worthwhile step that extends the patio's life and appearance, which is why the calculator offers it as an add-on. In freeze-thaw and salt regions especially, sealing is cheap insurance against surface scaling.

Most residential concrete patios are completed in 1 to 3 days of active work. The crew excavates and grades the area, sets the gravel base and forms, places any reinforcement, then pours and finishes the concrete — usually a one- to two-day sequence. Decorative finishes like stamping or exposed aggregate add finishing time, and later, sealing. After the pour, the concrete cures: it's typically safe to walk on after 24–48 hours, but keep furniture and heavy items off it for about a week, and full strength comes at around 28 days. Removing an old patio first adds time. Cold weather slows curing and may require covering the slab. Plan the project around the cure window — putting furniture or a hot tub on a green slab too soon risks cracking. The calculator estimates cost; your contractor will give a schedule.

Sometimes, but it's often not ideal. Pouring a new overlay or slab over an existing patio can work if the old surface is structurally sound, stable, and properly prepped, and if the added height won't cause drainage or door-clearance problems. But any cracks or movement in the old patio tend to telegraph up through the new concrete, and bonding requires careful surface preparation. In most cases — especially if the existing patio is cracked, heaving, or uneven — removing the old surface and pouring on a fresh, properly compacted base gives a far more durable, longer-lasting result. Overlaying a failing patio usually just delays and hides the underlying problem. That's why the calculator includes an option to remove the existing patio first (+$3/sq ft for demolition and disposal); for a sound slab you might overlay, but for a damaged one, tear-out is the better investment.

For the right project, yes. Stamped concrete presses patterns into the wet slab to mimic stone, brick, slate, or wood, with color hardener and release agents for realistic tone — giving a high-end, custom look at less than the cost of real stone or pavers, and at the highest concrete rate (~$16+/sq ft). It's worth it when curb appeal and a premium appearance matter, when you want the paver/stone look without paver maintenance (no joints to weed or re-sand), and when the patio is a focal point. The trade-offs: it costs roughly double a broom finish, needs resealing every 2–3 years to keep its color and pattern, can be slippery when wet (an anti-slip additive helps), and shows surface wear over many years. For a budget or utility patio, broom finish is the smart spend; for a showcase outdoor living space, stamped often justifies the premium. The calculator prices both so you can weigh it.

Concrete is low-maintenance, but a little care keeps it looking good and lasting for decades. Sweep and rinse it regularly, and clean stains (oil, grease, leaf tannin, rust) promptly before they set. Reseal every 2–3 years — essential for decorative finishes, beneficial for plain ones — to resist stains, moisture, and freeze-thaw scaling. In cold climates, avoid rock salt and chloride de-icers, which accelerate surface flaking; use sand for traction instead. Keep water draining away from the slab (clear gutters and grade), since pooling and freeze-thaw drive most concrete damage, and caulk any control-joint or hairline cracks with a flexible sealant before water gets in. Trim back roots and plantings that could heave the edge. Done consistently, this routine keeps a concrete patio crack-controlled and attractive for its full 25–30+ year life. The calculator includes a sealer add-on as part of that protection.
