Concrete Patio Cost: Bags vs. Truck vs. Contractor
It's not really a three-way choice. Bags vs. truck is a material decision — the crossover sits at about one cubic yard, and volume answers it almost by itself. DIY vs. contractor is a separate labor decision, and for a patio that's really a finishing-skill question. The two combine into three practical routes, and the one most comparisons skip — truck delivery with DIY placement — is often the best value on the table.
Decision one — bags or truck? This is a volume question. The crossover sits at about one cubic yard, and published sources broadly agree. Below it, bags. Above it, ready-mix. Nearly mechanical.
Decision two — DIY or hire it? This is about finishing, not mixing strength. A patio is a visible surface with a short finishing window — a skill question, not a strength question.
You can mix them. Truck delivery with DIY placement is a legitimate, common route most comparisons skip entirely — you buy the cheap material and keep the labor. The only combination that doesn't happen in practice is a contractor working from bags.
The three routes, at a glance
| Route | Material cost per cy | What you supply |
|---|---|---|
| Bags + DIY | $150–$500, depending on bag price | Everything — mixing, placing, finishing |
| Truck + DIY | $125–$195 plus fees | Placing and finishing — the truck does the mixing |
| Contractor | Included in the installed price | A check |
Route 1: Bags
| 80 lb bag yield | 0.60 cubic feet — 45 bags per cubic yard |
| 60 lb bag yield | 0.45 cubic feet — 60 bags per cubic yard |
| 80 lb bag price | Commonly cited from $4.50 to $9.00 — sources disagree sharply, see below |
| Cost per cubic yard, published range | $150–$500 depending on bag price and size |
| Mixer rental | $45–$90 per day across sources |
| Mixer capacity | Commonly covers up to about 1 cubic yard comfortably in a single day |
| Bagged mix strength | Commonly 4,000–5,000 psi at 28 days — higher than the 3,000 psi residential minimum |
| Water per 80 lb bag | About 3.8 quarts, commonly published |
| Bag disposal | Many municipalities charge for it |
Across published 2026 sources, an 80 lb bag is quoted anywhere from $4.50–$6.00, to a specific retail listing around $5.98, to $7–$9 "at major retailers" — nearly a 2x spread, and it flows straight through to cost per cubic yard: at $5 a bag you're paying about $225/cy; at $8 a bag, about $360/cy. One source notes plainly that local big-box pricing can vary by $0.50–$1.50 per bag on its own. The only bag price that actually matters is the one on your shelf — check it, multiply by 45, and compare against a ready-mix quote. Every published figure here is a placeholder for that number.
The hidden costs of bags
| Mixer rental | $45–$90/day. Commonly described as effectively required above roughly 15 bags for a consistent mix. |
| Hand-mixing waste | Mixing by hand rather than mechanically commonly costs roughly 11% more material, from uneven water addition and mixing losses. |
| Partial bags | The last bag on a job is almost always a partial. Budget 1–2 extra bags per 10 ordered on small pours. |
| Bag disposal | Charged by many municipalities. |
| Transport | 45 bags is 3,600 lb — exceeds most half-ton pickup payloads. Plan multiple trips. |
| Your time | See below — this is the big one, and it never appears in a price comparison. |
Route 2: Ready-mix truck
| Delivered price | Commonly cited $125–$195 per cubic yard |
| Most homeowners pay | $130–$150 per yard for standard 3,000–4,000 psi |
| Short-load fee | $50–$150, for orders under the supplier minimum |
| Typical minimum | 3–5 cubic yards |
| Full truck | 8–10 cubic yards |
| The clock | Commonly cited as needing to be used within 90 minutes before it hardens |
| Waiting time | Billed if your forms and crew aren't ready |
| Consistency | Professionally batched for uniform strength |
| What you still need | Wheelbarrows, floats, and helpers |
When bags arrive, you work at your own pace. When a truck arrives, you have about ninety minutes, and the driver bills for waiting. For a 4-yard patio, that means placing, screeding, and beginning to finish 400 square feet in the time it takes to watch a movie — with concrete stiffening the whole while. Have your forms and crew ready before the truck arrives to avoid waiting-time charges. This is why truck-plus-DIY works well up to a point and then stops working: the material got cheaper, but the clock got harder.
Route 3: Contractor
| Installed, plain patio | Commonly cited $6–$12 per square foot, national average around $8 |
| Most projects land | $8–$10 per sq ft |
| Broader published patio range | $5–$18 per sq ft |
| Labor share | 45–55% of the installed price |
| What's included | Materials, labor, finishing, and basic site prep on level, accessible ground |
| Stamped or decorative | $15–$30 per sq ft |
| Stained (as an add-on) | $3–$11 per sq ft |
Bids for identical scopes commonly vary by around 40% by region — see the slab cost guide for the full regional breakdown.
The labor nobody prices
| Volume | Bags (80 lb) | Reported labor |
|---|---|---|
| 0.5 cy | ~23 | Comfortable half day |
| 1.0 cy | ~45 | Commonly cited as 3–4 hours mixing and placing with one helper |
| 1.2 cy — a 10×10 patio | ~62 | "A solid day of hard work" |
| 1.5 cy | ~68 | 5–8 hours reported for 56–74 bags |
| Per cubic yard, general | — | Commonly cited as 4–8 hours of hard physical work |
Bag counts above are this site's own computed figures at 10% waste. One published source describes a cubic yard as "27 bags," which appears to confuse 27 cubic feet with bag count — the correct figure is 45 bags of 80 lb per cubic yard, confirmed by this site's own formula.
A 10×10 patio is a modest project — about 1.36 cubic yards, roughly 62 bags of 80 lb mix, described by one source as "manageable for a reasonably fit person with help, but it's a solid day of hard work." The same source adds: "if you have truck access, ready-mix delivers all that concrete in minutes." That contrast is the honest comparison — not $200 against $400, but a day of your life against fifteen minutes of unloading. For a 10×10 patio, a truck with a short-load fee is often cheaper than bags and saves the day. The bag route wins on convenience only when the volume is genuinely small.
Use the calculator below to size your own patio — pre-filled at this exact 10×10 example:
A 10×10 ft slab poured 4 in thick needs about 62 80-lb bags of concrete, or 1.36 cubic yards of ready-mix — that's roughly 5,000 lb of concrete.
Six patios, three ways
Volumes and bag counts below are computed from this site's own formula at 4 inches thick with 10% waste — the same math behind the slab calculator. Dollar figures use commonly cited per-unit prices; check your own local rates.
8×10 ft — 80 sq ft
| Route | Cost | Notes |
|---|---|---|
| Volume | 1.09 cy with waste | ~49 bags of 80 lb |
| Bags | $220–$440 material, plus $45–$90 mixer | Right at the crossover — 3–4 hours with a helper |
| Truck + DIY | $136–$212 concrete + $50–$150 short load = $186–$362 | Cheaper than bags at most bag prices |
| Contractor | $480–$960 at $6–$12/sq ft | $640 at the $8 average |
10×10 ft — 100 sq ft

| Contractor | $800–$1,800 (published figure) | $800 at the $8 average |
12×12 ft — 144 sq ft
| Route | Cost | Notes |
|---|---|---|
| Volume | 1.96 cy with waste | ~89 bags of 80 lb |
| Bags | $400–$800 material, plus mixer | Approaching impractical by hand |
| Truck + DIY | $245–$382 concrete + short load = $295–$532 | Clearly the better material route |
| Contractor | $864–$1,728 | $1,152 at the $8 average |
12×16 ft — 192 sq ft
| Route | Cost | Notes |
|---|---|---|
| Volume | 2.61 cy with waste | ~118 bags — not a sensible bag job |
| Bags | $530–$1,060 material | Roughly 10–20 hours of mixing — don't |
| Truck + DIY | $326–$508 concrete + short load = $376–$658 | Still under the 3–5 yd minimum |
| Contractor | $1,152–$2,304 | $1,536 at the $8 average |
16×20 ft — 320 sq ft
| Route | Cost | Notes |
|---|---|---|
| Volume | 4.35 cy with waste | ~196 bags — not viable |
| Bags | Not applicable | — |
| Truck + DIY | $543–$847 concrete, likely no short-load fee | Placing 320 sq ft in 90 minutes is a real crew job |
| Contractor | $1,920–$3,840 | $2,560 at the $8 average |
20×20 ft — 400 sq ft
| Route | Cost | Notes |
|---|---|---|
| Volume | 5.43 cy with waste | ~245 bags — not viable |
| Bags | Not applicable | A cited comparison: roughly $700–$1,000 delivered versus $1,400–$2,000 in bagged materials alone |
| Truck + DIY | $679–$1,059 concrete, full minimum met | Genuinely demanding — about 4 hours of professional crew time to do right |
| Contractor | $2,400–$4,800 (published range) | $3,200 at the $8 average — materials $1,200–$2,800, labor $1,200–$2,400 |
At 80 sq ft, bags are competitive. At 144 sq ft, they commonly cost more than the truck route and take a day. At 400 sq ft, published figures put bagged materials at $1,400–$2,000 against $700–$1,000 delivered — roughly twice the price for vastly more work. One source states the rule for that size flatly: at this scale, bagging becomes physically impractical and the cost premium is significant. The underlying reason: bagged concrete commonly costs $150–$500 per cubic yard against $125–$195 for ready-mix. You pay more per yard for the privilege of mixing it yourself. Bags win only when the volume is too small for a truck to be worth calling.
What makes a patio different from a shed pad
Nobody inspects a shed floor. Everyone looks at a patio, every day, for twenty years. The finishing window is short and it doesn't wait for you to learn — screeding, floating, edging, jointing, and brooming all happen in sequence on setting concrete, and a poor finish can't be repaired, only ground down or covered. So the honest DIY question for a patio isn't "can I mix concrete." It's "have I finished a slab this size before." If the answer is no, and the patio is visible from the kitchen window, the contractor premium is buying a specific skill, not just labor.
The freeze-thaw problem with bags
Bagged mix is strong — standard products are commonly rated 4,000–5,000 psi, which exceeds the 3,000 psi residential minimum. But strength isn't what survives freeze-thaw cycling; air entrainment is, and it's introduced during batching. You can't reliably get it from a bag.
A ready-mix plant will add air entrainment on request. An 80 lb bag won't. For an outdoor patio in a cold climate, that may matter more than the price difference — ask your ready-mix supplier for air entrainment and treat it as a specification, not an upsell. See the mix ratios guide for more on what air entrainment does and why it can't be added after the fact.
The water sensitivity problem
| Water per 80 lb bag | About 3.8 quarts, commonly published |
| The penalty | Commonly cited: just 1 extra quart can cut strength by up to 40% |
| More broadly | Overly wet concrete can lose 50% or more of its strength |
| The mixing rule | Mix on the dry side — you can add water but can't remove it. Start with 75–80% of the recommended water, mix thoroughly, then add the rest gradually until it reaches a thick, workable consistency. |
| Why bags are worse here | You're making dozens of separate batches — every one is a chance to over-water, and a properly stiff mix is genuinely hard to work by hand |
| Ready-mix advantage | One batch, professionally proportioned, consistent across the whole slab |
Bagged DIY carries a real risk of weak spots if improperly mixed, while ready-mix is professionally batched for uniform strength. On a patio, inconsistent batches show up as color variation across the finished surface — permanently. A mechanical mixer helps: it produces a more consistent water-cement ratio than hand mixing, which is a second reason the mixer rental isn't optional much above about 15 bags.
The decision, by volume
| Volume | Material route | Labor route |
|---|---|---|
| Under 0.5 cy | Bags — below any minimum; a short-load fee would dominate | DIY, comfortable |
| 0.5–1.0 cy | The crossover — compare your actual shelf price against a delivered quote | DIY with a mixer and a helper |
| 1.0–2.0 cy | Truck — bags cost more and take a day | DIY possible; the 90-minute clock is manageable |
| 2.0–4.0 cy | Truck | DIY is demanding — get help or hire it |
| Over 4 cy | Truck, always | Hire it, unless you've poured slabs before |
By everything else
| If... | Then |
|---|---|
| The patio is visible from the house | Weight the contractor option heavily — finish quality is permanent |
| You're in a freeze-thaw climate | Ready-mix with air entrainment specified, not bags |
| The truck can't reach the site | Bags, or a pump — and a pump is its own contractor with its own minimum |
| You want a decorative finish | Contractor — stamping is a timed operation on setting concrete |
| You've poured slabs before | Truck + DIY is the value route, and it's a real saving |
| You've never finished concrete | A patio is a poor place to learn |
| You have no helper | Reconsider anything over about 1 cy — the clock doesn't care |
| Budget is the binding constraint | Truck + DIY — you save the labor half, 45–55% of the installed price |
The saving, quantified honestly
A 12×16 patio (192 sq ft, 2.61 cy):
| Contractor, at the $8/sq ft average | $1,536 |
| Truck + DIY: | |
| Concrete, 2.61 cy at $150 | $392 |
| Short-load fee | $100 |
| Gravel base | $150 |
| Forms, mesh, sealer | $200 |
| Tool rental | $150 |
| Total | $992 |
Saving: about $544 — and a weekend, and the finish risk.
The DIY saving is capped by the labor share. Labor is 45–55% of installed cost, so on a $1,536 patio the labor component is roughly $700–$850. You can't save all of it, because you still buy gravel, forms, mesh, and tool rental that a contractor would have bundled. The realistic saving on a mid-size patio is a few hundred dollars against a weekend of hard work and a permanent finish you've never attempted. That's a legitimate trade for some people and a bad one for others — the point is making the trade visible, not pushing either way.
Mistakes worth avoiding
- Comparing bag price to truck price per bag — compare per cubic yard. Bags run $150–$500/cy against $125–$195 delivered.
- Using a published bag price instead of your own shelf price — sources vary from $4.50 to $9.00 per 80 lb bag.
- Forgetting the mixer rental — $45–$90/day, effectively required above about 15 bags.
- Hand-mixing to save the rental — costs about 11% more material and produces a less consistent water-cement ratio.
- Not budgeting partial bags — the last bag is almost always a partial. Add 1–2 per 10.
- Over-watering to make mixing easier — one extra quart in an 80 lb bag can cut strength by up to 40%.
- Assuming bags are fine for a cold-climate patio — you can't reliably get air entrainment from a bag.
- Ordering a truck without the forms ready — waiting time is billed, and the 90-minute clock is running.
- Attempting a large patio solo with a truck — 400 sq ft is about 4 hours of professional crew time.
- Learning to finish concrete on a visible patio — a poor finish can't be repaired, only ground or covered.
- Hauling 45+ bags in one pickup trip — 3,600 lb exceeds most half-ton payloads.
- Forgetting bag disposal — many municipalities charge for it.

Common questions
Is it cheaper to use concrete bags or a ready-mix truck for a patio?
Depends entirely on volume. Below about 1 cubic yard, bags usually win on cost and convenience — you're under every ready-mix minimum. Above about 1 to 1.5 cubic yards, a truck is almost always cheaper per yard, because bagged concrete commonly runs $150 to $500 per cubic yard against $125 to $195 delivered.
Can I order ready-mix and place it myself instead of hiring a contractor?
Yes — this is a real, common route most comparisons skip. You buy the cheap material and keep the labor saving, which is roughly 45 to 55% of an installed price. The catch is the 90-minute working window once the truck arrives, which makes this route demanding above a few cubic yards without help.
How many bags of concrete does a 10x10 patio need?
About 62 bags of 80 lb mix for a standard 4-inch-thick patio, including a 10% waste allowance — roughly 1.36 cubic yards total. Commonly described as a solid day of hard work for one person with a helper.
Why can't I use bagged concrete for a patio in a cold climate?
You can, but it's a real trade-off. Bagged mix is strong — often rated 4,000 to 5,000 psi — but strength isn't what survives freeze-thaw cycling; air entrainment is, and it's introduced during batching. A bag can't reliably deliver it. A ready-mix plant can add air entrainment on request for an outdoor patio in a freeze-thaw climate.
What's the biggest mistake people make comparing bags to ready-mix?
Comparing the price of one bag to the price of one cubic yard instead of converting both to the same unit. Bagged concrete commonly runs $150 to $500 per cubic yard depending on bag price, against $125 to $195 delivered — always compare per cubic yard, using your own local shelf price.
