Rebar is short for reinforcement steel or reinforcing steel, and it’s a heavy-duty steel bar used in reinforced concrete and brick structures. The purpose of rebar is to strengthen and stabilize the concrete when it’s under pressure or tension. While concrete is fairly strong under compression, it has weak tensile strength — which is why many people add rebar to strengthen a structure and keep it supported. This guide has some helpful information if you’re wondering about the rebar cost per foot. You’ll also discover the different factors that can help you answer the question, “how much does rebar cost?”
This material typically costs between $0.70 and $0.80 per linear foot, not including the cost of labor to install it. Remember that steel prices can fluctuate wildly depending on current market conditions, so your total rebar cost may vary depending on the current pricing. It’s best to check with your local supplier to determine how much you’ll pay when you’re ready to start your project.
The national average price to install rebar ranges from approximately $400 to $800. This statistic depends on the type of rebar you purchase and the quality of the steel, as well as current market prices and demand for installation. The most common rebar size for residential projects is rebar #4 (priced at about $0.30 to $2.00 per linear foot). Another common rebar type is #5 rebar, which costs more at $0.45 to $2.55 per linear foot. These strong steel bars are placed inside concrete to give a building more stability and strength. Many concrete contractors will include the cost to add rebar in their total estimate for your project cost.
Let’s examine other factors that determine how much rebar will cost for your project.
|What you can expect|
|Range per square foot:||$1.03||$1.21|
|Range for this type of project:||$516||$605|
Rebar Reinforcement Cost
Cost of grade-40, steel #4 reinforcing bar fastened on 1.5' grid spacing. Rate is inclusive of local delivery, as well as standard excess for perfect installation and occasional repairs.
Rebar Reinforcement Labor, Basic
Labor cost, under typical conditions, for complete installation. Rebar will be placed, secured, and connections tied. Rebar grid will be elevated with dobies. Fee is inclusive of all aspects of the project, such as thorough planning, acquisition of equipment and material, preparation and protection of project site, and meticulous cleanup.
Rebar Reinforcement Job Supplies
Requisite supplies for the job, including reinforcing materials and additives, isolation materials, and agents for cleaning and chemical release.

To decide on your total rebar cost, the amount you’ll usually pay is based on the length and diameter — which can range from $0.18 to as high as $6.20 per linear foot. For most residential applications, your contractor will use #3, #4, or #5 rebar in grades 40 or 60. The grade refers to the strength of the rebar or how many pounds per square inch it can handle. Most rebar manufacturers measure the grade based on the KSI or the kilopound per square inch.
This critical part of the construction is designed to support structures and weight. The grade ratings look at both the yield and tensile of the rebar. The yield strength is measured when the rebar starts to change shape, while the tensile strength is determined when the rebar breaks or fails
Let’s take a closer look at the various options and prices available for most residential projects.
Rebar #3 is the smallest size available and is just 3/8 inches in diameter. This rebar costs between $0.18 to $1.25 per linear foot — common in lighter, non-load-bearing applications like a walkway, patio, or driveway. This rebar is also called grade 40 and 60 size #3.
This rebar is ½-inch in diameter and is commonly used for foundation floors, walls, and larger driveways. Rebar #4 comes in grades 40 and 60 and costs between $0.30 and $2.00 per linear foot.
Rebar #5 is also available in grades 40 or 60 — usually the largest size compatible with residential construction. This rebar is 5/8 inches in diameter and works well with foundation beams, footings, and standard foundations. It costs between $0.45 and $2.55 per linear foot.
Rebar #6 and anything larger than this size isn’t ideal for residential construction. This option is a much heavier gauge steel bar most often used for industrial and commercial purposes. You can find #6 through #8 rebar used in heavy-duty applications such as retaining walls, high-rise buildings, and parking garages.
Steel is the most common material used to make rebar, but rebar can also be made from other types of metal. The type of rebar you’ll need when inputting information into a rebar calculator could depend on the installation location and application, so it’s best to consult a professional contractor to determine which one will be required.
Your contractor may need to use rebar stirrups — parts that hold the sections of the rebar together. Each rebar stirrup may cost $5 to $20 or higher, depending on the size. These stirrups are either square or rectangular and are between 6 to 36 inches or larger — depending on the application.
When purchased in bulk, rebar is typically priced by ton. Plan to spend from $850 to $2,500 per ton of bulk rebar. Importantly, you likely won’t need to buy this material in bulk for most standard residential applications. Typically, only large wholesalers or contractors purchase rebar this way.
Depending on where you live, you could pay more for rebar. For example, if you live in a rural area where less stock is available or demand is high, your price per linear foot will likely be higher.
The cost of rebar also depends on the current steel market rate. The price of steel per pound fluctuates depending on market conditions. The price will also go up if there are any supply chain issues at the time of your order.
Based on the grades mentioned above, your rebar cost will also vary depending on which option you need. Generally, the higher the rebar grade, it will cost more than lower grade options. The price will also depend on the size, which includes both the rebar's length and diameter.
Installing rebar requires skill and a thorough understanding of concrete and the specialty tools required to cut, bend, and tie the rebar. You’ll also need to be able to read and understand engineering or architectural construction plans. If not installed correctly, rebar can be a safety risk that may cause the concrete to sag, crack, or even collapse over time. While you may want to try installing rebar yourself to save some money, this home project is best left for professionals to handle. Look for a local concrete installation company or a concrete floor installer to ensure the rebar job is done right.
