Bags to Cubic Yards Converter
Convert bag count to cubic yards, or cubic yards to bag count, for concrete mix, mulch, topsoil, sand and gravel. The per-bag yield used is always shown.
What this converter does
This tool converts between bag count and cubic yards for common bagged materials, using each product's typical per-bag cubic-foot yield (27 cu ft = 1 cubic yard).
How the math works
- Cubic yards → bags: cubic yards × (27 ÷ yield per bag in cu ft), rounded up.
- Bags → cubic yards: bags ÷ (27 ÷ yield per bag in cu ft).
Why not just use a generic converter?
A generic converter has no idea how much a bag of concrete mix or mulch actually yields — that's a product-specific fact, not a fixed unit ratio. This tool bakes in real published yields for six common bagged products so you get a real bag count or volume, not a guess.
Worked example
1 cubic yard of concrete using 60 lb bags: 27 cu ft ÷ 0.45 cu ft per bag = 60 bags exactly — the commonly cited "60 bags per yard" figure for 60 lb mix.
Frequently asked questions
How many bags of concrete are in a cubic yard?
60 bags of 60 lb mix, or 45 bags of 80 lb mix.
How many bags of mulch make a cubic yard?
About 13.5 bags of standard 2 cu ft bags — round up to 14 when buying.
Is it cheaper to buy soil or mulch in bags or bulk?
Bulk is usually cheaper per unit at larger quantities; bags avoid delivery minimums for small projects.
Why do bag yields differ between brands?
Weight and yield vary by manufacturer and moisture — check your specific bag's printed yield for large orders.
Limitations
Yields are typical published figures, not a live reading from your specific bag. This tool doesn't calculate how much material a project needs from its dimensions — for that, see BuildMaterialPlanner's concrete or mulch calculators.

Already know your project dimensions?
If you're planning a concrete slab or mulch bed rather than converting a bag count you already have, BuildMaterialPlanner's concrete calculator works out bags or ready-mix cubic yards directly from your slab dimensions.
