Rebar Cost Estimation Calculator

What is rebar cost estimation calculator?

Rebar Cost Estimation Calculator helps determine how many rebars you need to create support in a concrete slab and how much it will cost.

How do I calculate how much rebar I need?

To determine the total linear rebar footage required, multiply the number of rebars you calculated for each side by the length measurement. Add those numbers together for the total number of linear feet of rebar you’ll need.

Step One: Figure Out the Grid Spacing

Rebar is often installed in a grid pattern, and to estimate the amount needed it will be important to first identify the size and spacing that is appropriate for your project. For a patio, it is common to use a #3 bar spaced every 18″-24″ while for a driveway #4 bar is often used with a 12″-18″ spacing.

Different projects require different size rebar and will require the rebar to be spaced differently. Most projects require rebar to be laid in a grid pattern with bars running in opposite directions and overlapping.

The use of steel or fiber mesh can be used as an alternate form of reinforcement in some circumstances and is often used for thinner slab pours. 

Step Two: Estimate the Rebar Grid Clearance

Once you have identified the specs for your rebar, you’ll need to identify how much clearance or space is needed between the rebar grid and the edge of the slab. This is needed to determine both the lengths of the rebar and how many rows and columns are needed.

Subtract the clearance from the length and width to find the dimensions of the grid. For example, if the slab is 10′ x 10′ and the clearance is 3″, the size of the rebar grid will be 9′ 6″ x 9′ 6″.

Step Three: Estimate the Rows and Columns

Find the number of bars needed for each direction by dividing the width of the grid by the desired spacing. For example, if the width is 9′ 6″ and the spacing is 18″, the number of columns would be 8.

9′ 6″ = 114″
114″ / 18″ = 6.3
round 6.3 up to 7 to get complete coverage
add 1 additional bar for the last edge

The length of the bars will be the opposite dimension of the grid. Repeat this process to find the number of rows for the opposite direction.

What size rebar do I need for a 6-inch slab? | Rebar Cost Estimation Calculator

For example, a slab that is 6 inches thick might have a rebar marked as size 6 or 3/4-inch. Slabs for septic tanks may require the use of both welded wire fabric and rebar. In such applications, using size 3 and 4 rebars is common.

How is rebar purchased?

The most common purchase method of rebar is buying in the ton. The most common rebar sizes, #3, #4, and #5 come in bundles of 266, 149.7, and 95.9 20-foot sticks per ton. Also, fluctuations in the steel market impact the price of a ton of rebar daily.

How much rebar is in a footing?

Determine the amount of rebar needed for the footings. Generally, one stick of rebar per 8 inches of footing width will suffice. If your footings are 16 inches wide, you will need to add two sticks of rebar along the width of the footing; however, if your footings are 24 inches wide, you will need three sticks.

Preliminary Estimate:

Preliminary Estimate is an initial estimate, it is impossible to see all the details of the project and potential problems, the brain simplifies everything and does not allow to assess the real scale.

Quantity Estimate:

Quantity Estimate includes a list of quantities for all materials needed to complete a project. Its purpose is to give the client a complete list of the required amounts for the project and the cost for each quantity. The processes of identifying, defining, combining, coordinating, controlling and completing the various processes and activities associated with the project.

Bid Estimate:

A bid estimate is an estimate that is submitted to the owner by the contractor.

There are three types of cost estimates which are listed below:

  • Control Estimates
  • Design
  • Bid

To make an accurate estimate, the project team will likely use at least some of the following tools and inputs:

  • An estimation software
  • Stick estimating
  • Market trends
  • Labor costs
  • A historical cost database and unit prices


  • Preparation of Budget Documentation.
  • Independent Examination of Estimate Documentation.
