The **Rebar Cost** calculator computes the total cost (**TC**) of rebar based on the length being purchased(**TL**), length of the individual pieces being bought (**uL**) and unit price (**uC**) of one piece of rebar.

**INSTRUCTIONS:** Choose units and enter the following:

- (
**TL**) Total Length of Rebar being purchased - (
**PO**) Percent Overage to account for waste - (
**uL**) Length of pieces of rebar (stick) being purchased (e.g. 20 ft, 40 ft or 60 ft) - (
**uC**) Cost of one piece (stick) of rebar. (Default is current price of 20 ft size 4 stick)

**Cost of Rebar (TC):** The calculator returns the following:

- total cost of the rebar in U.S. Dollars
- number of rebar sticks, and
- total length accounting for overage in feet.

Values with units can be automatically converted to compatible units (e.g. dollars to pesos) via the pull-down menu.

The following are price estimates of rebar products based on the current market price of steel and a reasonable markup from raw steel to retail rebar product.

You have computed that you need 840 feet of 1/2" (size #4) grade 60 rebar using the Rebar Calc at vCalc. You've shopped around and found that you can buy rebar for $7.6 USD per 20 foot piece at a rebar factory store. You can now use this calculator to compute total cost of rebar.

You enter:

**TL**= 840 feet**uL**= 20 feet. This is the length of the individual pieces of rebar you can buy.**uC**= $7.6 USD. This is a unit cost of $7.6 USD for #4 20' grade 60 pieces.

**Cost of Rebar (TC)** is returned at current market price for that length in U.S. dollars.

Rebar is short for reinforcing bar. Rebar is a roughly circular steel bar with ribs used to provide added tensile strength to concrete structures. Rebar is put in place before concrete is poured. When the concrete has hardened, the concrete around the rebar ribs keep the rebar in place. Rebar and concrete expand similarly with temperature variations. This all has the net result of substantially added tensile strength when rebar is part of the concrete form. Carbon steel is the most commonly used material for rebar, which may also be coated with zinc or epoxy resin.

Rebar is laid out in grids, crisscrossed patterns of rebar, tied at the intersections where runs of rebar touch. The grids have spacing between the rebar rows, and they are placed within the concrete form by a specified inset from the edge of the concrete. Multiple parallel grids, at uniform space intervals, are referred to as rebar mats.

- Rebar - reinforcing steel bar.
- Stick - one length of rebar. In the U.S., the most common lengths of rebar sticks are 20', 40' and 60'.
- Lapping - when two sticks of rebar are overlapped and bound together.
- Lapping Factor - the multiple of a rebar diameter used to specify appropriate rebar lapping length.
- Mat - a crisscross grid of rebar sticks. There may be more than one mat with space in between mats.
- Size - the indicator of the diameter of rebar sticks. Note: guage is not a correct term for rebar.

In the United States, rebar sizes are in increments of 1/8^{th} inches in diameter. Therefore, size 4 is 4/8^{th} of an inch, which is 1/2", and size 8 is a full inch in diameter. Based on this and the density of steel used in rebar, the Rebar Size Table contains reasonably accurate specifications of rebar linear weight and lateral (face) area based on rebar size.

The most common lengths of pre-cut rebar in the United States are 20`, 40' and 60'. These are known as rebar sticks. When the dimensions of a slab, wall or other form exceed the length of a single stick of rebar, it is required to overlap and tie rebar pieces to create the added length. This process is called lapping, and the length of the overlapping rebar is the rebar lapping length. The length of the lap is specified by a "Lapping Factor (LF)" which is often 40 or 60 times the diameter of the rebar. Engineering specifications of a lapping factor should always be applied.

#3 - 3/8" | $5.69 USD | $10.52 USD |

#4 - 1/2" | $7.6 USD | $18.95 USD |

#5 - 5/8" | $13.85 USD | $29 USD |

#6 - 3/4" | $21.44 USD | $42.2 USD |

#8 - 1" | $39.4 USD | $72.44 USD |

The above price estimates are derived from the current market price of steel and an observed markup from raw steel to rebar products.

A class of rebar tools, both powered and manual, have been developed to aid construction workers in working with rebar. These include the following:

- Rebar Cutters are used to cleanly and safely cut sections of rebar.
- Rebar Benders are used to bend rebar sticks precisely to fit into concrete forms.
- Rebar Tiers are used to tie rebar grid intersections and for rebar lapping.
