How It Works
Mulch is bought by the cubic yard, and the right quantity depends on three things: the area you're covering, the depth you want, and the type of mulch itself. Pinning those down keeps a 2026 landscaping budget honest, whether you're hauling home bags or scheduling a bulk delivery.
Volume comes first, in cubic feet, by multiplying Length x Width x Depth. Dividing that figure by 27 turns it into cubic yards. The bag count divides the volume by 2 cubic feet, the standard bag size for shredded mulch (0.074 cubic yards per bag), and the material cost multiplies cubic yards by a bulk price for the mulch type you pick: $30 for hardwood, $35 for pine bark, $40 for cedar and $120 for rubber.
Careful measurement up front beats rounding generously, since padding the area too much leaves you with surplus you didn't need. Depth is where coverage usually falls short: aim for at least 2-3 inches if you want real weed suppression. Finer mulches also settle and compact more than coarse ones, so a small buffer is worth folding in for those.
Example: Mulching a rectangular garden bed
- 1 Input: A garden bed is 20 feet long and 10 feet wide. You want a mulch depth of 3 inches (0.25 feet) using shredded hardwood mulch (2 cubic feet per bag).
- 2 Calculation: Area = 20 ft x 10 ft = 200 sq ft. Volume = 200 sq ft x 0.25 ft = 50 cubic feet. Cubic yards = 50 / 27 = 1.85 cubic yards. Bags needed = 1.85 cubic yards / 0.074 cubic yards/bag = 25 bags.
- 3 Result: You will need approximately 1.85 cubic yards of shredded hardwood mulch, which equates to about 25 standard 2-cubic-foot bags.
- 4 Context: For bulk delivery, you would order 2 cubic yards to ensure full coverage. If buying bags, you'd purchase 25 bags, about $100-$175 at $4-$7 a bag; the calculator's material cost uses bulk prices per cubic yard, which come out lower.
