How Many 80 lb Bags of Concrete Are in a Yard?
Part of Concrete & Masonry
Quick answer
It takes 45 × 80 lb bags to make one cubic yard of concrete. Each 80 lb bag yields about 0.6 ft³, and a cubic yard is 27 ft³, so 27 ÷ 0.6 = 45 bags.
Pre-mixed concrete bags list a yield — the volume of wet concrete one bag makes. Divide a cubic yard (27 ft³) by that yield to get the bags per yard.
Bags per cubic yard by size
| Bag size | Yield per bag | Bags per yard | Total made |
|---|---|---|---|
| 40 lb | 0.30 ft³ | 90 bags | 27 ft³ (1 yd³) |
| 60 lb | 0.45 ft³ | 60 bags | 27 ft³ (1 yd³) |
| 80 lb | 0.60 ft³ | 45 bags | 27 ft³ (1 yd³) |
Mixing 45 bags by hand is a serious amount of work. Once you're past about a cubic yard, ordering ready-mix delivered by truck is usually cheaper and far faster.
