How Many 60 lb Bags of Concrete Are in a Yard?
Answer first: 60 bags of 60 lb concrete = 1 cubic yard (27 ft³). Each bag yields 0.45 ft³. At $5–6/bag, bags cost $300–360/yd³ vs $120–165 for ready-mix delivered.
How Many 60 lb Bags in a Yard? Quick Answer
| Bags needed | Mix size | Cubic feet | Note |
|---|---|---|---|
| 60 bags | 60 lb | 27 ft³ = 1 yd³ | No waste added |
| 66 bags | 60 lb | 29.7 ft³ | With 10% waste |
| 72 bags | 60 lb | 32.4 ft³ | With 20% waste |
60 bags of 60 lb concrete = exactly 1 cubic yard. Each 60 lb bag yields 0.45 ft³, and 1 yd³ = 27 ft³. At $5–$6 per bag, that's $300–$360 per yard in bags vs $120–$165 for ready-mix delivered.
One cubic yard of concrete takes about 60 bags of 60 lb concrete mix when each bag yields 0.45 cubic feet. If you add a 10% waste factor, plan for about 66 bags.
Use the Concrete Bag Calculator if you want to change the yield, waste factor, bag price, or project dimensions. This guide is the quick 60 lb bag answer for one cubic yard.

Quick answer
Common planning estimate:
| Concrete volume | 60 lb bag yield | Bags before waste | Bags with 10% waste |
|---|---|---|---|
| 1 cubic yard | 0.45 ft3 | 60 bags | 66 bags |
Always check the yield printed on the actual bag you plan to buy. Fast-setting mixes, high-strength mixes, and specialty products can vary.
Formula
One cubic yard equals 27 cubic feet.
60 lb bags per yard = 27 cubic feet / 0.45 cubic feet per bag
60 lb bags per yard = 60 bags
If you include waste:
bags to buy = round up(60 x (1 + waste percentage))
With 10% waste:
60 x 1.10 = 66
buy 66 bags
Waste factor examples
| Waste factor | Calculation | Bags to buy |
|---|---|---|
| 0% | 60 x 1.00 | 60 bags |
| 5% | 60 x 1.05 = 63 | 63 bags |
| 10% | 60 x 1.10 = 66 | 66 bags |
| 15% | 60 x 1.15 = 69 | 69 bags |
For simple forms, 5% to 10% waste is a practical planning range. Use more if the base is uneven, the forms vary in depth, or the pour shape is irregular.
How much does one yard weigh in bags?
One cubic yard using 60 bags of 60 lb mix is:
60 x 60 lb = 3,600 lb of dry mix
With 10% waste, 66 bags is:
66 x 60 lb = 3,960 lb of dry mix
That weight is before water and does not include moving, opening, mixing, and placing each bag. At one cubic yard, compare bagged concrete with ready-mix delivery using the Ready-Mix vs Bags Calculator.
Cost example
If one 60 lb bag costs $4.50:
60 bags x $4.50 = $270.00 before waste
66 bags x $4.50 = $297.00 with 10% waste
That is material cost only. It does not include tax, tools, mixer rental, base material, reinforcement, delivery fees, labor, or cleanup.
For a fuller cost check, use the Concrete Cost Calculator after you know your bag count.
60 lb bags vs 80 lb bags
60 lb bags are easier to lift than 80 lb bags, but they create a higher bag count for the same volume. For one cubic yard before waste:
| Bag size | Common yield | Bags for 1 yd3 |
|---|---|---|
| 60 lb | 0.45 ft3 | 60 bags |
| 80 lb | 0.60 ft3 | 45 bags |
If both sizes are available, compare price per cubic foot and total handling effort. For many small jobs, 60 lb bags are a comfortable middle ground. For larger jobs, the lower count from 80 lb bags or a ready-mix delivery may be worth comparing.
FAQ
How many 60 lb bags are in one cubic yard of concrete?
Using a common 0.45 cubic foot yield, one cubic yard takes about 60 bags of 60 lb concrete mix before waste.
How many 60 lb bags should I buy for one yard with waste?
With a 10% waste factor, buy about 66 bags of 60 lb concrete mix for one cubic yard.
How many cubic feet are in a 60 lb bag of concrete?
A 60 lb bag commonly yields about 0.45 cubic feet of mixed concrete. Check the product bag because yield can vary by mix.
Is one yard of concrete too much to mix from 60 lb bags?
It can be done, but one yard can mean 60 to 66 bags. Compare ready-mix delivery before committing, especially if the pour needs to be placed quickly.
When Should You Use 60 lb Bags?
60 lb bags are the middle-ground option — lighter than 80 lb bags but more efficient than 40 lb bags:
- Post holes and footings under 0.5 yd³ — fence posts, deck footings, mailbox bases where you need a manageable bag weight
- Aging or solo DIYers — the 15 lb weight difference from an 80 lb bag matters over dozens of bags on a hot day
- Small slabs and pads under 1 yd³ — sheds, AC pads, steps, and small walkways where ready-mix has a minimum-load fee
- Tight spaces — when a concrete truck cannot access the pour site and you are hand-mixing
For projects over 1 cubic yard (60+ bags of 60 lb), compare the total bag cost to a ready-mix quote. At $5/bag × 60 bags = $300 in bags alone — ready-mix at $145–$170/yd³ is typically competitive once you factor in mixer rental and labor time.
