How Many 60 lb Bags of Concrete in a Cubic Yard?

One 60 lb bag of concrete covers 0.45 cubic feet — so you need exactly 60 bags of 60 lb concrete to make one cubic yard. The calculation is straightforward: 1 cubic yard = 27 cubic feet, and 27 ÷ 0.45 = 60 bags exactly. This is the most commonly asked concrete bag question, and the answer every contractor and DIY homeowner needs before buying concrete for any project.

This concrete bags per yard calculator has three modes: bags per cubic yard (enter CY, get bag count for any bag size), project calculator (enter slab, cylinder, or footing dimensions, get bags needed), and volume per bag (enter bag count, get total cubic feet and cubic yards). All four common bag sizes are covered — 40 lb, 60 lb, 80 lb, and 90 lb — with Quikrete-specific data, a water per bag mixing guide, and a mortar per block reference.

Use the calculator above — select your bag size and get your count instantly.

How Many Cubic Feet in a 60 lb Bag of Concrete?

One 60 lb bag of concrete equals 0.45 cubic feet of mixed concrete. This is equivalent to 0.017 cubic yards per bag. To cover 1 cubic foot of volume you need 2.22 bags of 60 lb concrete. To cover 1 full cubic yard you need exactly 60 bags.

Para los trabajadores hispanohablantes: cuanto cubre una bolsa de concreto de 60 libras — cada bolsa de 60 libras cubre 0.45 pies cúbicos (0.45 cubic feet). Para una yarda cúbica (cubic yard) se necesitan 60 bolsas. Una bolsa de 80 libras cubre 0.60 pies cúbicos — se necesitan 45 bolsas por yarda cúbica.

40 lb Bag of Concrete — Cubic Feet, Quikrete Specs, and Best Uses

A 40 lb bag of concrete yields 0.30 cubic feet of mixed concrete (0.011 cubic yards). It takes 90 bags of 40 lb concrete to fill one cubic yard. The 40 lb bag is the lightest common bag size, making it ideal for solo DIY work where lifting 60 or 80 lb bags is impractical.

Quikrete 40 lb Bags — Product Details

• Quikrete Concrete Mix 40 lb (#1101-40): standard grey concrete mix, 4,000 psi at 28 days
• Quikrete Fast-Setting 40 lb (#1102-40): sets in 20–40 minutes — no mixing required for fence posts
• Quikrete 5000 High Early Strength 40 lb: reaches 2,000 psi in 24 hours
• Available at: Home Depot (~$5–6 per bag), Lowe's, Menards, Walmart, and local hardware stores

The 40 lb bag is the most manageable for solo DIY projects — easy to lift and carry without assistance. It is ideal for small repairs, stepping stones, fence posts in softer soil, small footings, or anywhere you need concrete in tight spaces. For projects requiring more than 20–30 bags, the 80 lb bag is more cost-effective per cubic foot. Most major retailers stock 40 lb bags on the same shelf as 60 lb and 80 lb — compare unit price per cubic foot, not per bag.

How Much Water Per Bag of Concrete — 40, 60 & 80 lb Guide

Getting the water-to-concrete ratio right is critical. Too little water and the mix is dry and crumbly. Too much water and the final concrete is weak. Here are the recommended amounts for each common bag size:

Quikrete 80 lb High Strength Concrete Mix — Specifics

Quikrete 80 lb concrete mix (#1101-80) — also called Quikrete 80 lb High Strength Concrete Mix — is the most popular bagged concrete product in the US. Recommended water: approximately 0.9 quarts (0.85 litres) per bag. Mix time: 3–5 minutes by hand, or 1–2 minutes with a mechanical mixer. Initial set: 2–4 hours. Full cure: 28 days for 4,000 psi.

Quikrete concrete mix 80 lb bag water consistency check: the mix should hold its shape when squeezed in your fist without being soupy, glossy, or leaving excess water on the surface. Adding too much water reduces compressive strength significantly — every extra quart per 80 lb bag reduces strength by approximately 20%. Start with less water than you think you need and add small amounts gradually.

How Many Bags of Mortar Per Block — Concrete Block Mortar Guide

One 60 lb bag of mortar mix covers approximately 12–13 standard 8×8×16 concrete blocks with standard 3/8-inch mortar joints. For 100 standard blocks, you need approximately 8 bags of 60 lb mortar mix (or 6 bags of 80 lb mortar mix).

These estimates are for standard CMU (concrete masonry unit) blocks at 8×8×16 inches with 3/8-inch mortar joints. For different block sizes or joint thicknesses, coverage changes significantly. Always add 5–10% extra mortar bags to account for waste and uneven application.

Bagged Concrete vs Ready-Mix — When to Use Each

Bagged concrete is cost-effective for projects under 1 cubic yard — fence posts, mailbox posts, small footings, concrete repairs, and remote locations where ready-mix trucks cannot access. Ready-mix truck delivery makes more sense for any project over 1–2 cubic yards — driveways, patios, garage slabs, and footings.
