Ready-Mix vs Bags Break-Even Chart
Compare ready-mix vs concrete bags with break-even examples for 0.25-3 cubic yards, minimum loads, short-load fees, labor pressure, and access.
Use this ready-mix vs bags break-even chart when you need a quick planning answer before buying concrete. The exact break-even point depends on your bag price, bag yield, ready-mix price per cubic yard, minimum billable yards, short-load fees, delivery, access, equipment, and how many bags your crew can realistically mix and place before the concrete starts setting.
Quick answer: bags often make sense for repairs, post holes, and very small slabs under about 0.5 cubic yard. From about 1 cubic yard upward, compare ready-mix even if the delivered quote looks expensive. Once the job reaches dozens of 80 lb bags, labor, timing, consistency, and finish risk can matter more than the material-only price.
This page is a planning chart, not a supplier quote. Confirm local prices, delivery minimums, truck access, and contractor scope before ordering.
After the chart shows a close call, open the Ready-Mix vs Bags Cost Comparison to review delivered totals, bag labor, short-load fees, access, and quote scope before choosing bags or scheduling a truck.
Citation-ready break-even chart
The live data asset below expands this article with downloadable CSV/JSON rows for three scenarios: a standard 3 yd minimum, a small-load or volumetric supplier, and a high fixed-fee access case. The static table remains here for readers who need the quick 3 yd minimum example in plain text.
These examples use common planning assumptions:
- 80 lb bag yield: 0.60 cubic feet.
- 80 lb bag price: $5.50.
- Bag equipment or pickup allowance: $50.
- Ready-mix price: $165 per cubic yard.
- Ready-mix minimum billable load: 3 cubic yards.
- Ready-mix fixed fee allowance: $150.
| Planning volume | 80 lb bags before waste | Bagged material + $50 allowance | Ready-mix with 3 yd minimum + $150 fee | Planning read |
|---|---|---|---|---|
| 0.25 yd3 | 12 bags | about $116 | about $645 | Bags usually win unless access or labor is unusual. |
| 0.50 yd3 | 23 bags | about $177 | about $645 | Bags are still plausible, but mixing effort is real. |
| 1.00 yd3 | 45 bags | about $298 | about $645 | Compare ready-mix; labor and timing may dominate. |
| 1.50 yd3 | 68 bags | about $424 | about $645 | Ready-mix often becomes worth pricing seriously. |
| 2.00 yd3 | 90 bags | about $545 | about $645 | Material gap is small; effort and finish risk are high. |
| 3.00 yd3 | 135 bags | about $793 | about $645 | Ready-mix usually wins on price and practicality. |
Use this chart as a first pass. If your supplier has a lower minimum, a volumetric truck, or a short-load option, ready-mix can become competitive earlier. If truck access is poor or the supplier fee is high, bags can stay competitive longer.
Break-even formula
Use the same planning volume on both sides.
For bags:
bag count = ceiling(cubic yards x 27 / bag yield in ft3)
bagged total = bag count x bag price + pickup/equipment allowance
For ready-mix:
billable yards = max(cubic yards, supplier minimum billable yards)
ready-mix total = billable yards x price per yard + fixed delivery/short-load/access fees
Then compare the totals with the practical jobsite questions:
- Can the crew mix and place that many bags fast enough?
- Will the slab, footing, or pad suffer if placement is slow?
- Can the truck chute reach the forms?
- Will you need a pump, buggy, wheelbarrow route, or extra helper?
- Does the ready-mix quote include delivery, fuel, tax, environmental fees, short-load charges, and wait time?
Volumetric or low-minimum delivery example
Some suppliers price small loads differently. If a volumetric or small-load supplier charges $185 per cubic yard plus a $95 delivery fee, and your bagged option uses the same $5.50 80 lb bag with a $50 pickup/equipment allowance, the material-only break-even can move closer to 0.75 cubic yard.
| Planning volume | Bagged estimate | Small-load ready-mix estimate | Planning read |
|---|---|---|---|
| 0.50 yd3 | about $177 | about $188 | Very close; access and timing decide. |
| 0.75 yd3 | about $237 | about $234 | True break-even range in this scenario. |
| 1.00 yd3 | about $298 | about $280 | Ready-mix starts to win before labor. |
| 1.50 yd3 | about $424 | about $373 | Ready-mix usually wins unless access is bad. |
This is why one national break-even number is misleading. The supplier minimum and fixed fees matter as much as the per-yard price.
When bags are usually the better buying path
Bags are usually easier to justify when:
- the job is under 0.5 cubic yard;
- the work is a repair, post hole, fence line, small pad, or remote corner;
- truck access is poor;
- you can stage bags close to the forms;
- finish quality is not threatened by slower mixing;
- the ready-mix supplier has a high minimum or short-load fee.
Common bag-friendly jobs include fence posts, mailboxes, small step repairs, small generator pads, and isolated patches.
When ready-mix deserves a quote
Ready-mix deserves a serious quote when:
- the job approaches 1 cubic yard or more;
- the pour needs consistent concrete and fast placement;
- the surface will be visible, finished, broomed, or floated;
- the bag count is high enough to slow the crew;
- the slab needs a continuous placement window;
- you can place from the truck chute or with a short wheelbarrow route.
Common ready-mix comparison jobs include patios, sidewalks, garage slabs, shed bases, driveway pads, and larger footings.
What to ask before ordering ready-mix
| Quote question | Why it changes the break-even |
|---|---|
| What is the minimum billable yardage? | A 1 yd3 job billed as 3 yd3 may lose on price but still win on labor. |
| Is there a short-load fee? | This fixed fee can dominate small jobs. |
| Is delivery included? | Delivery, fuel, and environmental fees change the delivered total. |
| How long can the truck wait? | Wait-time charges matter if forms, crew, or access are not ready. |
| Can the chute reach? | Pump, buggy, or wheelbarrow labor may erase the ready-mix advantage. |
| What PSI and mix design is quoted? | Compare the same concrete, not just the cheapest yard price. |
What to check before buying bags
| Bag question | Why it matters |
|---|---|
| What is the actual mixed yield? | Bag labels and mixes vary; bag count depends on yield. |
| How many bags can you move? | 80 lb bags are heavy before mixing and heavier in total pallet quantities. |
| How fast can you mix? | Slow placement can hurt finish quality on slabs. |
| Do you need a mixer rental? | Equipment cost shifts the break-even point. |
| Is water access ready? | Staging and mixing logistics affect pour timing. |
| Do you need help finishing? | Material math does not include finishing labor. |

FAQ
What is the ready-mix vs bags break-even point?
There is no universal break-even point. With a high ready-mix minimum, bags may look cheaper until around 2 cubic yards. With a volumetric or low-minimum supplier, ready-mix may compete near 0.75 to 1 cubic yard.
How many 80 lb bags equal one cubic yard?
One 80 lb bag commonly yields about 0.60 cubic feet, so one cubic yard takes about 45 bags before waste. With 10% waste, plan about 50 bags.
Are bags cheaper than ready-mix?
Bags can be cheaper for very small jobs, but they become labor-heavy quickly. Ready-mix can cost more on the invoice and still be the better choice when the job needs fast placement or consistent concrete.
Should I include labor in the break-even?
Yes. Material-only math is useful, but it is incomplete. Mixing dozens of bags can add time, fatigue, equipment rental, and finish risk.
Why does the ready-mix minimum matter so much?
Many suppliers bill a minimum load. If your job needs 1 cubic yard but the supplier bills 3 cubic yards, your delivered total may be based on the minimum, not the actual volume.
Is this a quote?
No. This is a planning chart. Confirm local bag prices, supplier yard prices, delivery fees, access, and contractor scope before ordering concrete.
