Concrete Driveway Cost Calculator

Why use a driveway cost calculator

You may have been in this exact spot: your driveway is cracked, sinking, or just plain ugly, so you start calling contractors. The first quote comes in at $3,500. The second, for what sounds like the same job, comes in at $7,000. Somewhere in there is also the question you haven’t even answered yet — concrete or asphalt? — and every contractor seems to push whichever one they happen to install.

None of that pricing is random. Driveway cost moves in predictable steps based on size, material, thickness, and finish. Once you know those levers, you can tell within a few minutes whether a quote is reasonable — and whether concrete or asphalt actually makes more sense for your budget and timeline.

How much does a concrete driveway cost?

Every driveway estimate comes down to the same three steps.

All of that math is exactly what the calculator above runs automatically — switch to the Driveway tab, enter your size, and you’ll see concrete and asphalt costs side by side.

A worked example

Let’s say you’re planning a 20×20 ft driveway (400 sq ft), 4 inches thick, with a plain concrete finish.

That gap — roughly $1,200 to $1,600 upfront — is the number most homeowners fixate on. But it’s only half the story, which is exactly why the next section matters.

Asphalt vs. concrete: which is cheaper long-term?

What if you just look at the sticker price? Asphalt wins, no contest — it’s routinely 40–50% cheaper to install. What if you look at cost per year of service instead? The gap narrows dramatically, and depending on your climate and how long you plan to stay in the house, concrete can come out ahead.

Asphalt needs sealcoating every 2–3 years and typically gets resurfaced every 10–15 years — costs that add up over a 15–20 year lifespan. Concrete needs far less: occasional degreasing and resealing every 5–10 years, but it lasts 30–40 years before major work is needed. So if you’re planning to stay put for two decades or more, concrete’s higher entry price gets spread across a lot more years.

What about a concrete sidewalk?

First, measure length and width just like a driveway — most residential sidewalks are 4 feet wide. Then apply the same per-square-foot logic: a standard broom-finish sidewalk runs $6–12 per square foot installed, or roughly $24–48 per linear foot at that standard width. A typical 50-foot sidewalk (200 sq ft) lands at $1,200–$2,400.

What if you’re replacing an old, cracked sidewalk instead of pouring new? Add $2–6 per square foot for removal and haul-away on top of the new-installation cost. And what if only part of it is damaged? Partial replacement of just the bad sections can cut the total cost by 40–60% compared to redoing the whole walkway.

Switch to the Sidewalk tab in the calculator above to run your own length and width and get an instant cost range, including the per-linear-foot breakdown.

Common mistakes to avoid

• ✕Comparing asphalt and concrete on price alone. A cheaper asphalt quote can cost more over 20 years once resealing and resurfacing are factored in.
• ✕Skipping the permit check. Driveways almost always need a permit since they connect to the public right-of-way — patios usually don’t.
• ✕Ignoring thickness for heavier vehicles. A standard 4-inch slab is fine for cars, but trucks, RVs, and heavy equipment need 5–6 inches to avoid cracking.
• ✕Forgetting demolition costs on a replacement. Removing an old driveway or sidewalk adds a real line item that some quotes leave out until later.
