Quick Answer
Bag yield used: 0.45 ft³ per bag. Bag yield guide
Project Notes
Check the bag yield on the label and plan for how many store trips the total weight may require, especially if you are buying in smaller batches.
Ordering too many batches can lead to excess material that may not be usable.
Focus on steady placement to maintain an even finish and avoid weak spots in the concrete.
Practical Notes
With 20 cubic feet of concrete, you can create durable patios or walkways. This volume is ideal for small slab pours, making it perfect for DIY projects around your yard.
Transporting 45 bags totals approximately 2,700 pounds, so plan for multiple trips. Consider staging the bags close to your work area for easier handling during your project.
While bagged concrete is manageable for small projects, if your needs exceed this volume frequently, ready-mix might offer a more efficient solution.
How to Use This Estimate
Confirm volume
Start with 20 cubic feet and verify whether your total is in cubic feet or cubic yards.
Check bag yield
This page assumes 0.45 ft³ per 60 lb bag.
Add waste
Use the 5% or 10% buffer if you expect spillage, uneven forms, or small measurement errors.
Planning Notes
When bagged concrete makes sense: smaller pours, simple DIY jobs, and areas where a ready-mix truck is inconvenient.
When to compare ready-mix: once bag counts become very high, delivery may save labor and time. See our concrete cost per yard guide.

Frequently Asked Questions
How do I determine the yield of each bag?
Check the label on the bag for the specific yield information, as it can vary by brand and product.
Should I round up my order to account for waste?
It’s wise to round up your order slightly to cover any potential waste or errors in mixing.
When is using bagged concrete a good choice?
Bagged concrete is practical for small projects like patios, walkways, and shed slabs where ready-mix may not be necessary.
Are there situations where ready-mix might be better?
Ready-mix concrete could be more suitable for larger pours or projects requiring specific formulations.
