60 lb Concrete Calculator
This 60 lb concrete calculator converts your pour's dimensions straight into a bag count: one 60 lb bag yields about 0.45 ft³ of mixed concrete, so the tool divides your volume by that yield and rounds up with waste.
Comment utiliser ce calculateur
- Saisissez vos dimensions — pieds pour les longueurs, pouces pour l'épaisseur.
- Ajustez les options — pourcentage de perte, taille du sac et prix local du béton.
- Lisez vos résultats — le volume, les sacs, le poids et le coût se mettent à jour en direct.
La formule
Bags = volume ÷ 0.45 ft³ per bag, rounded up (+5–10% waste) Exemple résolu : A 10 × 10 ft slab at 4 in = 33.3 ft³ → 33.3 ÷ 0.45 ≈ 74 × 60 lb bags before waste.
The 60 lb bag balances yield and liftability. A concrete calculator 60 lb bags estimate uses 0.45 ft³ per bag — 60 bags per cubic yard, exactly 4 bags per 1.8 ft³ mixer load. It's the most popular size for fence posts and small pads.
Reference numbers for 60 lb bags: 60 bags make one cubic yard, 79 bags make one cubic meter. Keep those in your head at the store and you can sanity-check any estimate.
Bagged concrete makes sense up to roughly one cubic yard. Beyond that, price out ready-mix — mixing 45+ bags by hand is a full day of hard labor and the per-yard cost usually favors the truck.

How much concrete does a 60 lb bag make?
About 0.45 ft³ of mixed concrete, per standard manufacturer yield data.
How many 60 lb bags in a cubic yard?
60 bags per cubic yard (27 ft³ ÷ 0.45 ft³, rounded up).
How many 60 lb bags for a fence post?
A 12 in hole 24 in deep needs ≈ 1.57 ft³ — about 4 bags per post.
Should I add extra bags?
Yes — buy 5–10% more than calculated. Unopened bags return easily; a mid-pour shortage doesn't.
