Bulk Mulch Calculator
Plan a delivery by cubic yards, truck loads, staging pile footprint, density weight, settling allowance, and overage for multiple beds or direct square footage.
Choose a starting point, then adjust bed count, load size, rounding, and pile shape for the actual delivery site.
Bulk Mulch Delivery Estimate
Calculated from bed area, depth, settling, overage, and delivery rounding.
These options update after each calculation so you can compare common supplier rounding choices before scheduling a truck.

|---|---|---|---|
| 3 yd³ | About 38 sq ft pad | About 20 ft long | Good for compact driveways |
| 5 yd³ | About 53 sq ft pad | About 34 ft long | Leave room for shovel access |
| 10 yd³ | About 84 sq ft pad | About 68 ft long | Often one large dump pile |
| 20 yd³ | About 134 sq ft pad | About 135 ft long | Split loads if space is tight |
| Order amount | 2 cu ft bags | 3 cu ft bags | At 3 inch depth |
|---|---|---|---|
| 1 yd³ bulk | 14 bags | 9 bags | About 108 sq ft |
| 3 yd³ bulk | 41 bags | 27 bags | About 324 sq ft |
| 5 yd³ bulk | 68 bags | 45 bags | About 540 sq ft |
| 10 yd³ bulk | 135 bags | 90 bags | About 1,080 sq ft |
A calculated 7.2 yd³ need may become 7.5 yd³, 8 yd³, or one 10 yd³ load depending on supplier minimums and truck capacity.
Mulch piles spread wider than they look from the truck. Keep the pile on a firm surface, away from drains, tree trunks, and tight gates.
Ordering mulch by the truck is a process that is significantly different from ordering mulch in bags. When ordering mulch by the truck, the mulch come in a single pile in your yard, and the mulch pile remains in one location in your yard until you move the mulch. The amount of mulch that you order is another consideration in the ordering process.
If you order too little mulch, you may be charged extra delivery fee. However, if you order too much mulch, you may end up with piles of mulch left on your property. The mulch calculator take into account the dimension of your garden beds and the area that they cover, the depth that you would like to have the mulch, and any layer of mulch that already exist in your garden beds.
How to Order Mulch by Truck and Use a Mulch Calculator
The dimensions and the depth are two factors that the calculator takes into consideration because different mulch products settles in different amounts. For instance, hardwood mulch settles more less than leaf mulch and bark nuggets contains more air than shredded cedar mulch. The calculator accounts for these allowances, as is the rounding of the amount of mulch that is calculated.
The mulch supplier typically only delivers in whole load of mulch, so the mulch calculator is able to show how much extra mulch would be delivered as a result of rounding the calculated amount to the nearest whole load of mulch. The size of the truck that will deliver the mulch is another consideration for those who are purchasing mulch by the truck. For residential yards, ten-yard loads of mulch are typically sufficient.
However, mulch suppliers will typically only deliver in whole loads of mulch, and the order round up to the nearest whole load. Thus, the mulch calculator can show the number of loads of mulch that will be delivered in excess of the calculated amount of mulch due to these rounding rules, and the cost of the excess mulch. The mulch calculator can also estimate the space that the mulch pile will take up once it is delivered to your yard.
This consideration is important to make sure that you have flat space within your yard for the mulch pile. The weight of the mulch that will be delivered is another consideration for those who are purchasing mulch. While the volume of the mulch will be the same, the weight of the mulch can change based off the material that you order as well as the amount of water that is contained within the mulch.
If you have a narrow space in your yard, such as a gate, or if your lawn is soft and yields to the weight of the truck, then the weight of the mulch is another consideration to determine where the delivery truck can go. The depth of the mulch that you order is another consideration when you order mulch. Two inches of mulch may be sufficient for walkways in your yard, but may seem thin for some yard application.
Three inches of mulch is typically an even depth that is desired for garden beds to even out mulch thickness, suppress weeds, and yet still allow roots to breathe. Four inches of mulch or more only apply to those who would like to have a thick layer of mulch in their yard, and can be accounted for in the mulch calculator. The depth of the mulch can be adjusted in small increment with the mulch calculator to see how that affects the total amount of mulch needed.
The way in which you stage the mulch pile is another consideration prior to delivery of the mulch. A cone-shape mulch pile will take up less space in your yard than a long mulch windrow. However, a long mulch windrow may be easier to shovel if you have a flat area in your yard.
You must stage the mulch pile on firm ground in your yard, and you must ensure that there is enough space for a loader or a wheelbarrow to move around the pile. The mulch calculator can estimate the footprint of the mulch pile based upon the type of mulch pile you select in the calculator. Many people commonly make mistake when purchasing mulch.
One of the most common is to ignore the existing layer of mulch in the garden beds. Should people ignore the existing layer of mulch in their yard, they end up ordering too much mulch. Another mistake is to ignore the settling of the mulch that will be delivered.
If people ignore the settling of the mulch, they may find themselves without enough mulch to cover the bed once it rains. Finally, many people dont consider the rounding of the amount of mulch that will be delivered. If people do not account for the rounding of the amount of mulch, they may end up with an extra half load of mulch.
The mulch calculator will display both the amount of mulch that is needed versus what will be delivered (due to the various considerations above). The mulch calculator will provide you with a number, but it does not replace your judgment about the depth that you want the mulch to be, the dimensions of your mulch bed, and the type of mulch. However, once you have determined these variable and the volume of mulch that will be delivered by the calculator, you will have to decide on the number of loads, the size of the mulch pile, and the location of the mulch pile.
You, the customer, must manage these.
