Concrete Bag Cost Calculator

How Much Does an 80 lb Bag of Concrete Cost?

An 80 lb bag of Quikrete Concrete Mix (SKU 110180) runs $6.47 at Home Depot as a single bag, dropping to $6.15 per bag once an order reaches the retailer's own 42-bag pallet-quantity break. Both figures come from the same fetched product listing — not a rounded estimate — and this calculator pre-fills that price automatically while still letting you overwrite it with your own local price.

This is the single verified retail price behind every figure on this page. Everything else — the per-yard cost, the pallet savings, the ready-mix comparison — is arithmetic built on top of it, and it is always shown next to the date it was collected so you can judge how current it still is.

What the Concrete Bag Cost Calculator Does

Concrete Bag Price by Size — 40, 50, 60, 80 lb

Only the 80 lb bag has an independently verified retail price in this survey right now. The table below shows it alongside a clearly-labeled estimate for 40, 50, and 60 lb bags — the verified $6.47/bag figure expressed as a per-pound rate (about $0.08/lb) and scaled to each bag's weight. That estimate assumes the same brand prices every bag size at the same rate per pound, which packaging and handling costs may not actually hold true at the low end — treat the unverified rows as a planning number, not a quote.

The cost-per-cubic-yard column lands within a cent or two of $291.15 for every size, because a smaller bag costs proportionally less and covers proportionally less volume — under this per-pound assumption, switching bag size does not meaningfully change your total material cost. What it changes is handling: an 80 lb bag is heavier per lift but means fewer bags to carry, tear open, and mix for the same job.

Home Depot vs. Lowe's vs. Menards — 80 lb Bag Pricing

Retailer pricing is collected and verified one listing at a time, and right now only one of the three major home-improvement retailers has a collected, dated source behind its price. The table below shows exactly what has been verified — nothing more.

Lowe's and Menards pricing is not yet verified. No listing has been fetched for either retailer, so — per this site's anti-fabrication rule — no price is published for them here rather than guessing at a plausible-sounding number. If you commonly search for “80 lb bag of concrete at Lowe's” or a Menards price, that is exactly the gap this table is tracking; both rows will be filled in once a dated, sourced listing is collected, and the visible verification date above will move with them.

Bulk & Pallet Pricing

Buying a full 42-bag pallet of 80 lb concrete at the single-bag price would cost $271.74 (42 × $6.47). At the bulk rate it costs $258.30 instead (42 × $6.15) — a savings of $13.44 for ordering the same bags as a pallet instead of one at a time. That is Home Depot's own published pallet break, not a third-party discount code or a negotiated rate.

If you already know you are ordering by the pallet — or need to work out how many pallets a larger job requires, including weight and delivery logistics — calculate pallet quantity discounts plus loose-bag remainders and total delivered weight for all four bag sizes.

Cost Per Cubic Yard: Bagged 80 lb Concrete

It takes 45 bags of 80 lb concrete mix to make one cubic yard (27 ÷ 0.60 cu ft per bag). At the verified single-bag price, that's 45 × $6.47 = $291.15 — meaningfully more than most delivered ready-mix material pricing per yard, which is exactly why bags stop making economic sense somewhere around the one-yard mark. Buying enough bags at once to trigger bulk pricing brings it down to 45 × $6.15 = $276.75, a savings of $14.40 per yard — still bagged concrete, just bought smarter.

Bags vs. Ready-Mix: When Should You Stop Buying Bags?

Start with material cost alone, because that is where the two options are furthest apart. One cubic yard of bagged 80 lb concrete costs $291.15 at the verified single-bag price. Across the 19 metros in this site's own ready-mix price survey, 3,000 PSI ready-mix averages $147.10 per cubic yard — from $128.00 in Tampa FL to $177.00 in Boston MA. Bagged concrete is not slightly more expensive per yard; it is close to double. It is more expensive than ready-mix in every single metro in the survey, including the priciest one. Buying at pallet pricing narrows the gap to $276.75/yd and does not close it.

So why does anyone buy bags?

Because you cannot buy a third of a yard of ready-mix at the per-yard rate. Suppliers price small loads with a surcharge, a floor, or both, and the survey captured those terms verbatim from the primary suppliers' own published rate sheets:

Those charges do not scale with volume. They land in full on a quarter-yard pour, and they are the entire reason bags stay competitive at the bottom of the range — not the material price, which favours the truck everywhere.

Three bands, not one crossover point

Under about half a cubic yard (23 bags), bags win — and it is not close. Bagged material runs $148.81 against roughly $73.55 of ready-mix material, but a short-load fee on that delivery can exceed the entire bagged material cost on its own. Above about one cubic yard (45 bags), ready-mix wins on material cost even after a short-load fee, and the margin widens with every additional yard. Between those two figures sits a genuine judgment call — and price is not what decides it.

What actually decides the middle band: your time

Labour is the column most bag-price comparisons leave out entirely, and in the 0.5–1.0 yard band it is decisive. Assume 3–5 minutes per bag to haul it, open it, measure water, mix to a consistent slump, and place it — a working assumption, not a surveyed figure, and one you should replace with your own if you have mixed before. At that rate 45 bags is 2.25–3.75 hours of mixing alone, before forming, finishing, or cleanup, and assuming you do not slow down as the day goes on. Realistically it is most of a working day for one person, and the pour has to stay continuous enough to avoid cold joints while you do it. A ready-mix truck discharges the same yard in well under an hour. Value your own time at even $25.00 an hour and roughly $56.25–$93.75 of labour attaches to that 45-bag pour — enough to erase most of what is left of the comparison in the middle band. If you are paying a crew rather than donating your own Saturday, it erases it outright.

What this crossover does not know

Be careful what you carry onto the job site from any crossover figure, including this one. It does not know your supplier's minimum delivery charge, which the rate sheets above show can run into the hundreds on a small COD order — a user who trusts a crossover point that ignores a short-load fee will simply be wrong on the ground. It does not know whether a truck can physically reach your pour, or whether you would end up barrowing it a hundred feet regardless. It does not know whether you already own a mixer, which removes a rental line from the bagged column entirely, or whether you are pouring in stages where bags are more practical at any price. And ready-mix arrives with a fixed placing window, while bags let you work at whatever pace you can sustain. Get a real quote for your actual volume, your actual PSI, and your actual site access before treating any of this as settled.

Hidden Costs Beyond the Bag Price

The bag price is only the material line item. A few commonly overlooked costs regularly turn a “cheap” bagged-concrete job into one that costs about the same as calling a ready-mix truck once everything is added up:

• Delivery or pickup. Bags bought online or in bulk often carry a flat delivery or curbside-pallet fee separate from the per-bag price — factor it in before comparing against a ready-mix quote that already includes delivery.
• Mixer rental. Hand-mixing more than a few bags in a wheelbarrow is slow and physically demanding; a towable or walk-behind mixer typically rents by the day and adds a real cost most bag-price comparisons ignore entirely.
• Tools and consumables. Mixing hoes, wheelbarrows, finishing trowels, edgers, and plastic sheeting for curing are one-time or per-job costs that a ready-mix truck quote doesn't need at all, since the concrete arrives ready to place.
• Labor time. The most commonly underestimated cost of all. Mixing dozens of bags by hand — measuring water, mixing to a consistent slump, and placing before each batch sets up — consumes most of a day for a project a ready-mix truck would place in an hour. See the bags-vs-ready-mix section above for how that trade-off plays out at different project sizes.
