Concrete Slab Cost Calculator
Estimate the Cost of a Concrete Patio, Slab, Walkway or Concrete Pad.
Whether you want to install a new concrete slab, a concrete sidewalk, or a concrete patio, the calculator on this page will help you estimate the total project cost. While it’s going to cost between $4 to $8 per square foot to have new concrete installed. If you already have an existing pad, sidewalk or patio in place that needs replacement, expect to pay an extra $2.50 – $5.00 per square foot for demolition and disposal.

How to Use the Concrete Pad Cost Estimator
Before using the cost calculator above, you’ll need to know the estimated square feet of your concrete surface. If you’re unsure, you can measure it manually or do it from your device using Google Earth. If you do already know the square feet of your new concrete pad, skip down to the calculator section below.
-
- Go to Google Earth.
- Click the Search Icon in the left menu and search for your home address.
- Click the ruler icon in the left menu, and drop anchor points around the general perimeter of your concrete pad, patio or sidewalk area. If trees obscure your view, use your best judgment, based on your knowledge of your home and the space you want the concrete poured.
- On the right side, view the square feet of the area. (Note: The tiny arrow next to the measured size drops down to change the type of measurement if not already showing square feet.)
- Round the measurement to the nearest 10, then add 5% to the total when using the concrete pad cost estimator below. This is is to account for waste. For example, in the picture below it shows 1,280 square feet, so there is no need to round it to the nearest 10. Next, I’ll add 64 square feet (5%) to account for the waste, flared edges, transitions, etc. The correct number of square feet needed in the cost estimator is 1,344 sq ft.
Next – Use the following instructions to complete the concrete pad cost calculator.
- Step 1: Enter your 5-digit zip code and state.
This step allows us to factor in the general cost of living in your area. - Step 2: Input the square feet of your new concrete slab, and choose whether this is for a new slab, or replacing an existing concrete slab.
- Step 3 – Tell us whether you need a standard slab (4″), or heavy duty (6″) for strength. If you are adding an RV slab for example, heavy duty or a 6″ slab would be the better choice.
- Step 4 – Choose the type of finish: Smooth or Stamped.
- Step 5 – Check off all of the added costs that may apply. (conduit for wiring/sprinklers, flared edges, etc)
- Final Step: Review the calculated cost estimates and choose whether or not to send this information to local, professional concrete contractor to receive free cost quotes.
