Concrete Bag Yield Chart: 40, 60, 80 lb Bags
Use this concrete bag yield chart for 40, 60, and 80 lb bags, cubic feet, cubic yards, sq ft coverage, pallet yield, and quote checks.
A concrete bag yield chart shows how many cubic feet one bag makes after mixing. Yield is the number behind bag counts, square-foot coverage, pallet coverage, and ready-mix comparisons.
Use the Concrete Bag Calculator for exact bag counts, the Concrete Quote Reviewer for bid comparison, and the Concrete Proposal Kit for client-ready material line items. If the question is whether the calculated yield matches a ready-mix ticket, bag order, or placed volume, use the Concrete Yield Calculator Guide before calling the order short.
This page gives a compact yield-first chart, then connects bag yield to buying decisions: pallet weight, pickup loads, waste, ready-mix breakpoints, and quote checks when the bag count gets too high.
Quick answer
Common planning yields are:
| Bag size | Common yield | Cubic yards per bag | Bags for 1 yd3 before waste |
|---|---|---|---|
| 40 lb | about 0.30 ft3 | 0.011 yd3 | about 90 |
| 60 lb | about 0.45 ft3 | 0.017 yd3 | about 60 |
| 80 lb | about 0.60 ft3 | 0.022 yd3 | about 45 |
Always confirm the yield printed on the exact bag you plan to buy. Specialty mixes can vary.
Yield formula
cubic yards per bag = bag yield cubic feet / 27
bags needed = project cubic feet / bag yield cubic feet
Then add waste and round up to whole bags.
Coverage by thickness
| Bag size | 3 in thick | 4 in thick | 5 in thick | 6 in thick |
|---|---|---|---|---|
| 40 lb | about 1.2 sq ft | about 0.9 sq ft | about 0.7 sq ft | about 0.6 sq ft |
| 60 lb | about 1.8 sq ft | about 1.35 sq ft | about 1.1 sq ft | about 0.9 sq ft |
| 80 lb | about 2.4 sq ft | about 1.8 sq ft | about 1.4 sq ft | about 1.2 sq ft |

Pallet yield check
| Planning pallet | Dry mix weight | Approx. yield |
|---|---|---|
| 80 x 40 lb bags | about 3,200 lb | about 0.89 yd3 |
| 56 x 60 lb bags | about 3,360 lb | about 0.93 yd3 |
| 42 x 80 lb bags | about 3,360 lb | about 0.93 yd3 |

Buying workflow from the chart
Use the chart in this order when you are standing in a store aisle or checking a delivery cart.
| Step | What to do | Why it matters |
|---|---|---|
| 1 | Calculate project cubic feet. | Bag labels are usually in cubic feet. |
| 2 | Pick the exact bag size and product. | Yield can differ by mix type. |
| 3 | Divide volume by bag yield. | This gives the base bag count. |
| 4 | Add waste and round up. | Partial bags do not exist on pour day. |
| 5 | Check pallet and payload weight. | A full pallet can exceed vehicle limits. |
| 6 | Compare ready-mix if count is high. | Labor and finish timing may dominate price. |
The chart is especially useful when a calculator gives yards but the store sells bags. Convert yards to cubic feet first, then divide by the yield printed on the bag.
cubic feet = cubic yards x 27
bags = cubic feet / bag yield cubic feet
Store-run and pallet checks
A bag count can be mathematically correct and still be a poor buying plan. Ask whether the store has enough matching bags from the same product line, whether damaged bags are excluded, whether a pallet deposit or delivery fee applies, and whether your vehicle can carry the load safely. Keep bags dry before use; wet or hardened bags can change yield and workability.
For pallet-scale orders, compare the delivered bag price with ready-mix. A pallet may look convenient, but 42 common 80 lb bags are still less than one cubic yard before waste. Larger slabs may require multiple pallets, a mixer, extra helpers, and a longer placement window.
Quote and dispute use
Yield charts also help when a pour feels short. Before assuming the supplier, store, or crew made an error, compare the measured forms, actual thickness, waste, spillage, subgrade variation, and product yield. A small thickness change across a slab can use several extra bags. For ready-mix disputes, use a ticket and yield checklist rather than a bag chart alone.
Final order check
After the chart gives a bag count, verify the actual product label, store stock, vehicle payload, delivery option, weather protection, and return policy for unused bags. Keep bags from different products separate; do not assume a specialty mix yields the same as a standard mix.
If the order approaches pallet scale, run a second comparison against ready-mix. The cost of a pallet delivery, mixer rental, extra helpers, and slow placement can erase the apparent savings from bagged concrete. If the project must be finished continuously, the bag count is a workflow question as much as a math question.
Remeasure before buying
Use the chart after forms are set, not only from the sketch. Measure inside form dimensions, check thickness at several points, and note any thickened edges, step-downs, post holes, ramps, or low spots. Then rerun the count with the actual product yield and waste factor.
If the updated count changes by a half pallet or more, revisit delivery, mixer size, helper count, and ready-mix pricing before the store order is placed. A small number on a bag chart can become a heavy material-handling problem once pallets, weather protection, water, staging, cleanup, and finish timing are included.
FAQ
What is concrete bag yield?
Concrete bag yield is the mixed volume one bag produces, usually shown in cubic feet. It is used to calculate bag counts and coverage.
How many cubic feet are in an 80 lb bag?
A common planning yield is about 0.60 ft3, but confirm the exact product label.
How many cubic feet are in a 60 lb bag?
A common planning yield is about 0.45 ft3. Some specialty mixes may differ.
How many cubic feet are in a 40 lb bag?
A common planning yield is about 0.30 ft3. Always check the bag label before buying.
Is one pallet equal to one cubic yard?
Usually not exactly. A common 42-bag pallet of 80 lb bags is about 0.93 yd3 before waste.
