Direct answer: To calculate mulch, multiply bed square footage by depth in inches, then divide by 324. A 500 square foot bed at 3 inches deep needs about 4.6 cubic yards, so most Michigan homeowners would plan for 5 yards before the crew confirms the final install.
Use the calculator above for the first number, then use photos and measurements to turn that number into a real quote. The calculator cannot see curved beds, old mulch buildup, weeds, edging, or tight access.

Use these ranges for planning, not as a final quote. Mulch Bros installation starts at $130 per yard when delivery and professional installation are included, and the final number depends on bed prep, edging, cleanup, old mulch, access, and total yardage.
| Project type | Typical yardage | Installed planning range | What changes the quote |
|---|---|---|---|
| Small refresh | 2-3 yards | $260-$390 starting install range | Usually front beds, a few tree rings, or a light top-off. |
| Common residential job | 4-6 yards | $520-$780 starting install range | Typical for many Milford, Novi, and Brighton homes with front and side beds. |
| Full-property refresh | 7-10 yards | $910-$1,300 starting install range | Often includes front, sides, backyard beds, and more edging. |
| Large or detailed property | 11+ yards | $1,430+ starting install range | Final price depends heavily on access, prep, old mulch, and detail work. |
Yardage Chart for Michigan Beds
Most residential installs use a 3 inch target depth. A lighter refresh may need less material, while bare beds may need more coverage.
| Depth | Best use | Coverage per cubic yard |
|---|---|---|
| 2 inches | Light refresh over clean existing mulch | 1 yard covers about 162 sq ft |
| 3 inches | Standard Michigan landscape bed install | 1 yard covers about 108 sq ft |
| 4 inches | Bare or thin beds needing stronger coverage | 1 yard covers about 81 sq ft |
What We See Locally
Many established homes have curved beds and mature plants, so 4-8 yards is a common planning range.
Newer subdivisions often have larger front beds with cleaner access, which makes quotes easier to confirm.
Mixed lot sizes mean yardage can swing quickly, especially when backyard beds or tree rings are included.
Lake-area and wooded properties often need more cleanup, edging, and access planning.

Mulch Calculator FAQ
What is the mulch formula?
Square feet x depth in inches / 324 = cubic yards.
Should I round up?
Yes, a slight round-up helps avoid running short and lets the crew finish evenly.
What depth should I enter?
Use 3 inches for a normal Michigan install, 2 inches for a light refresh, and 4 inches for bare beds.
