How many bags of mulch do you need?
Add the area of each bed. Use a rectangle, triangle, circle, or an area you've measured elsewhere. For top-ups, we subtract the current mulch depth from your target depth before calculating volume. Then we add your extra allowance and divide by the bag's labeled volume. Round up once to whole bags.
A quick example
Two beds measure 12 × 6 ft and 8 × 4 ft. Together, that's 104 ft². At 3 in deep, they need 26 ft³ before extra. With 10% extra, that's 28.6 ft³, or about 1.06 yd³. That means 15 bags of 2 ft³ or 10 bags of 3 ft³. A supplier selling in half-yard increments would require 1.5 yd³, unless their minimum is higher.
Already know your volume?
Choose known volume above and enter cubic yards or cubic feet. One cubic yard is 27 ft³. For example, 1.06 yd³ is 28.62 ft³ and requires 15 whole 2 ft³ bags with 0% extra. Do not add another allowance if your volume already includes one.
Compare the full purchase
Enter your local bag price and bulk quote, including delivery and the supplier's minimum and increments. The cheapest option depends on the full quantity you must buy, not just the shelf price per unit. A blank price stays unavailable rather than being treated as $0.
What can change the final amount?
Curved edges are still estimates even when broken into simple shapes. Slopes, settling, bag yield, and supplier measurement can also change what arrives on site. Taxes and other fees are not included unless added to your quote. This is a purchasing estimate, not a guaranteed yield.
