How Much Does Rebar Cost?
#4 rebar — the most common size for residential slabs and footings — averages about $12 for a 20-foot stick in 2026, or roughly $0.60 per linear foot. Heavier sizes cost more. The table and calculator below help you estimate bars and tie wire for any project.

| Material | National | Northeast | South | Midwest | West |
|---|---|---|---|---|---|
| #4 rebar, 20 ft / stick | $12.00 | $13.80 | $11.04 | $11.64 | $13.44 |
| Tie wire roll / roll | $13.00 | $14.95 | $11.96 | $12.61 | $14.56 |
What affects the price
- Bar size — #3 (⅜″) is cheapest; #5 (⅝″) and #6 (¾″) cost more per stick.
- Length — 20-foot sticks are standard; cutting fees apply if custom lengths are needed.
- Tie wire and bar chairs add a small amount to total material cost.
- Rebar prices track steel commodity prices and can fluctuate significantly.

How this is calculated
- Bars width-way = floor(20 ft × 12 ÷ 12 in) + 1 = 21
- Bars length-way = floor(20 ft × 12 ÷ 12 in) + 1 = 21
- Total rebar = 21 × 20 ft + 21 × 20 ft = 840 ft
- Add 10% overlap & waste → 924 ft
- Sticks = ceil(924 ft ÷ 20 ft) = 47
- Tie points = 21 × 21 = 441
A grid needs one extra bar in each direction (the "bars + 1" rule) so both edges are covered.
Sticks include your overlap & waste allowance; lap splices typically overlap 40× the bar diameter.

Frequently asked questions
How much does rebar cost per linear foot? ⌄
#4 rebar (the most common size) averages about $0.60 per linear foot in 2026, based on a $12 price for a 20-foot stick at national home centers. Heavier #5 and #6 bar run proportionally more.
How much rebar do I need for a concrete slab? ⌄
A standard 10-inch rebar grid needs roughly 2.4 sticks per square foot of slab. Use our rebar calculator: enter slab dimensions and spacing, and it returns bars needed, total linear feet, and cost.
Can rebar be bent on-site? ⌄
Yes. A rebar bender (available at most tool rental shops) bends standard sizes cleanly. Home-center rebar comes in 20-foot lengths; most suppliers will cut to length for a small fee.
What size rebar for a concrete driveway? ⌄
Most residential driveways use #4 bar (½″) at a 12-inch grid. Heavier vehicles or soft subgrade may call for #5. Check your local code — some areas specify a minimum bar size.
