Rebar Cost Calculator

Estimate what rebar costs by the linear foot, from a dated national price band for black or galvanized bar, with a same-size per-pound and per-ton conversion for four common sizes.

Quantity

Using the sibling calculator’s standard 10×10 ft slab example — 140 ft of in-place rebar. Switch to “Enter my own” for a different quantity.

Reading this estimate

  • The width of the range is the honest partthe plain-carbon band alone spans $0.40 to $1.50 a foot because three dated sources disagree on scope and ceiling. A single confident number would hide that disagreement, not resolve it.
  • Per-pound and per-ton are same-size figures onlyavailable only for #3, #4, #6 and #8 — the sizes with their own priced foot-length. Dividing a generic multi-size band by one size’s weight was tried and rejected: it manufactures a spread wider than any real quote.
  • Galvanized has no per-pound price, on purposeits per-foot band is stated as the same regardless of bar size, but weight is not — there is no single weight to divide by without picking one arbitrarily, so the figure is left blank rather than guessed.
  • A blank price is a genuine gap, not a free itemepoxy-coated rebar, installation labour, and welded wire mesh per square foot all show no dollar figure because no dated source met this page’s standard — not because they cost nothing.
  • Every band shows its date and its confidencea band within 90 days of going stale is flagged in the build, and one past 365 days old fails it outright. The weakest band on this page should never read as solid as the strongest — check the date before treating a price as current.
  • This is a planning range, not a quoteit prices the bar only — cutting, bending, tying, and delivery are separate. For a number you can act on, take your exact quantity and bar size to a supplier for a current, delivered price.

Methodology

This page multiplies a linear-foot quantity by a dated price-per-foot range, low and high computed and shown separately. A same-size price divided by that same size’s own weight is the only route to a per-pound or per-ton figure — a generic multi-size band divided by one size’s weight was tried, found to manufacture a false spread, and is named below as the rejected route rather than quietly avoided. Every band carries a source, a date, and a confidence rating.

How rebar is priced: by the foot, and only by the foot

The main cost line is quantity in linear feet × a dated $-per-foot band for the chosen coating (black or galvanized). It does not vary by bar size — the sourced bands themselves are stated as applying "regardless of size" or across "common residential sizes" as a range, not a per-size figure. A separate, same-size point price (below) is what makes a per-pound or per-ton conversion possible for four specific sizes.

Quantity comes from the sibling calculator’s own in-place length — the standard 10×10 ft slab example carries over as 140 ft by default, or enter your own linear footage. This page does not re-derive how that length was computed; see /rebar-calculator for the grid and lap-splice formulas.

lowCost  = quantity_ft × band.low[coating]
highCost = quantity_ft × band.high[coating]

  140 ft, black: 140 × $0.40 = $56.00 — 140 × $1.50 = $210.00

Where the per-foot band comes from

Plain carbon-steel rebar in common residential sizes runs $0.40–$1.50 per linear foot (constructestimates.com, updated July 2026). That page’s own description gives $0.18–$9.00/ft across every size, grade and coating, and its body gives $0.18–$6.80/ft for carbon steel across every size and grade; an earlier guide (wellcoindustries.com, January 2026) gives $0.40–$1.25/ft for basic untreated steel — reported as a genuine disagreement about scope and ceiling, not merged into one number.

Galvanized rebar is shown as $1.20–$2.50/ft, low confidence. The $1.20 low end is what every source found states. The $2.50 high end comes from a single source (oneanddoneprep.com, June 2026); the more widely repeated figure puts the top at $1.60 (wellcoindustries.com, January 2026; constructestimates.com, July 2026). That $1.20–$1.60 figure recurs identically across several publishers, back to a cost-guide table dated May 2025 — one figure repeated, not several confirmations, and a newer publication date on it is not newer data — so this page shows the wider range and says why. Stainless runs up to $9.00/ft (wellcoindustries.com, January 2026), a ceiling rather than a low–high range, so it is not priced; the same $9.00 ceiling appears on constructestimates.com (across every size, grade and coating) and in the May 2025 table, so that is one ceiling repeated, not three confirmations. No current, dated per-foot price was confirmed for epoxy-coated rebar — see "What this page will not price" below.

The same-size-only per-pound rule — and the route we rejected

Converting a per-foot price to a per-pound price needs a price and a weight that share the SAME bar size. A dated per-size stick survey (vcalc.com, January 2026) prices #3, #4, #6 and #8 individually — dividing each size’s own price by that same size’s own weight gives $0.739–$0.757/lb, a tight 2.4% spread that falls inside two independently-quoted per-pound figures found elsewhere. This is the only route this page uses, and the only sizes it is offered for.

Those four prices are the weakest numbers on this page. The survey dates from 12 January 2026 and no newer dated source for individual bar sizes was found when this page was prepared (September 2026); the survey describes its own figures as estimates from a markup on the steel price. A guide dated a fortnight later (bhumicalculator.com, January 2026) puts the low end of every size 6% to 60% above them, and the US producer price index for concrete reinforcing bars rose 16.3% between January and August 2026 (BLS series WPU1074051, 331.421 to 385.370, the latest month preliminary). None of that is applied as an adjustment — it is context. Read the per-pound and per-ton figures as a January 2026 reading that is more likely to understate today’s price than to overstate it.

The route we tried first and rejected: dividing the generic $0.40–$1.50/ft band — which spans several bar sizes by the source’s own description — by one size’s weight (#4’s 0.668 lb/ft) gave $0.599–$2.246/lb, a 275% spread wider than any directly-quoted figure. The arithmetic was not wrong; the pairing was — that band’s width comes from spanning multiple bar sizes, not from market variance at one size, and dividing it by a single size’s weight conflates the two. This page never computes a per-pound or per-ton figure this way.

Galvanized has no per-pound figure at all, for the same reason from the other direction: its $/ft band is one range for every size, but weight is not — there is no single weight to divide by, and picking one size’s weight arbitrarily changes the answer (across three sizes, the same band’s low end alone moves from $0.45 to $1.80 per pound). Left uncomputed rather than guessing.

REJECTED:  genericBand.low_or_high ÷ weightPerFoot[oneSize]     (mixes two bar sizes’ worth of variance)
CORRECT:   sameSizeStickPrice[size] ÷ weightPerFoot[SAME size]   (#3, #4, #6, #8 only)

  #4: $9.99 ÷ 20 ft = $0.4995/ft ÷ 0.668 lb/ft = $0.747754/lb
  (short ton = × 2,000 lb; metric tonne = × 2,204.62 lb, both named explicitly, never a bare "ton")

Confidence, and how old these prices are

Every band on this page carries a source, a publish date, and a confidence rating, shown beside the price. The plain-carbon band is low confidence — dated sources disagree on scope and ceiling. The galvanized band is low confidence — one source sets its ceiling. The by-size stick survey is low confidence too: a single survey (a second page from the same publisher repeats the same figures, which is a duplicate, not a confirmation) that describes its own figures as estimates and has not been refreshed since January 2026.

The prices are re-checked on a fixed cadence: the build fails once a band passes 365 days old and warns during the 90 days before that. The by-size survey, dated 12 January 2026, is the oldest number on this page and the first due for a refresh — named here rather than left to read as current.

None of this is a live price, an API feed, or a crowd-sourced figure — every number is a dated range from a named source. Follow a retailer link for today’s exact price.

What this page will not price, and why that is the honest answer

Epoxy-coated rebar has no per-foot price on this page. The one figure found is a per-box price — $300–$400 per 50-lb box (constructestimates.com, July 2026) — for a bar of unstated size, which cannot be turned into a per-foot band; it also works out to $6–$8 per pound, against the $0.65–$1.00 per pound the other page carrying it (floridalumber.com, October 2023) gives for rebar in general, so it is not treated as a usable price. No dated per-foot price was found, so none is shown.

A per-pound or per-ton figure for galvanized rebar, or for any bar size outside #3/#4/#6/#8, is not computed — see "The same-size-only per-pound rule" above for why. The development length (ld) a lap splice needs is not this page’s concern at all; that is the sibling calculator’s lap-splice mode, and it is not computed there either (no sourced formula fits the inputs either page collects).

Installation and labour cost has no dated standalone source — this cost is typically bundled into a contractor’s overall bid rather than quoted as its own line, and this page states that convention instead of inventing a $/hour figure.

Welded wire mesh is not priced per square foot on this page — no dated source was confirmed for a rebar-specific mesh band. This page links to /concrete-cost-calculator’s existing $0.15–$0.30/sqft mesh band rather than restating or contradicting it; that band is not superseded here.

FAQ

How much does rebar cost per foot?
Plain carbon-steel rebar in common residential sizes runs $0.40 to $1.50 per linear foot (constructestimates.com, July 2026). That page describes its full range across every size, grade and coating as $0.18 to $9.00/ft (and gives $0.18 to $6.80/ft for carbon steel), and an earlier guide (wellcoindustries.com, January 2026) gives $0.40 to $1.25/ft for basic untreated steel — the sources genuinely disagree on scope and ceiling, reported rather than merged.
How much does rebar cost per pound?
For #3, #4, #6 and #8 — the only sizes with a same-size priced foot-length — dividing that size’s own price by its own weight gives $0.739 to $0.757 per pound (vcalc.com, January 2026). This is never computed by dividing a generic multi-size price band by one size’s weight — that route was tried, found to manufacture a false, much wider spread, and was rejected.
How much does rebar cost per ton?
From the same-size per-pound figure ($0.739–$0.757/lb), a short ton (2,000 lb) runs about $1,478–$1,513 and a metric tonne (2,204.62 lb) about $1,630–$1,668, for #3/#4/#6/#8 rebar. A separate commodity index (~$450–457 per metric ton, dailymetalprice.com) is a wholesale mill price, not a retail one — the two are not comparable figures.
How much does rebar cost at Home Depot?
Home Depot and Lowe’s sell rebar by the piece — commonly 10- or 20-ft lengths — at their own posted, store-specific prices, which this page does not reproduce or guarantee current. Use this page’s dated per-foot range to sanity-check a quoted price, then follow the retailer link for today’s exact number.
Where can I buy rebar?
Home Depot and Lowe’s carry rebar in most stores, typically cut to common stock lengths. Building-material and steel-supply yards often sell it by the piece or by the ton at lower per-foot prices for larger orders, and will cut to custom lengths. This page prices the material only — check locally for delivery and cutting options.
How much does galvanized rebar cost?
Galvanized rebar is shown as $1.20 to $2.50 per linear foot (low confidence) — a corrosion-resistant premium over plain steel for exposed, marine, or de-icing-salt environments. Every source found gives $1.20 as the low end; the $2.50 top is one source (oneanddoneprep.com, June 2026), while the more widely repeated $1.60 top recurs identically across publishers back to a May 2025 table, so it is one figure repeated rather than several confirmations. No per-pound or per-ton figure is given for galvanized: its price is one range for every bar size, but weight is not, so there is no single weight to divide by.
How much does epoxy-coated rebar cost?
No per-foot price is shown for epoxy-coated rebar. The one figure found is a per-box price — $300 to $400 per 50-lb box (constructestimates.com, July 2026) — for a bar of unstated size, which cannot be converted to a per-foot price; it also works out to $6 to $8 per pound, against $0.65 to $1.00 per pound for rebar in general on the other page that carries it (floridalumber.com, October 2023), so it is not treated as a usable price. This page will not show an epoxy price until a dated per-foot source is found.
How much does welded wire mesh cost, compared to rebar?
This page does not price welded wire mesh directly — mesh is sold by the sheet or roll, not by a bar-equivalent linear foot, and no dated rebar-specific mesh source was confirmed this run. See /concrete-cost-calculator’s existing $0.15–$0.30 per square foot mesh band for a sourced figure.
