Use this truckload estimator to plan dump truck trips for excavated soil, gravel, crushed stone, demolition debris, backfill, and site cleanup materials. It supports metric and US customary inputs, including cubic meters, cubic yards, kilograms, pounds, tonnes, short tons, and bulking factor adjustments for loose material.
Enter the measured bank or project volume, apply the expected bulking factor, then compare the loose material volume against truck bed capacity and payload capacity. If the starting quantity came from a dig, confirm the bank volume first in the excavation calculator before converting it into hauling trips.
The final estimate uses the larger trip count so hauling plans account for both the space available in the dump body and the legal or practical weight limit. For loose-volume staging examples after excavation, compare your scenario with the spoil pile examples guide.
Every truck has two limits: how much it can hold by volume (cubic meters or cubic yards) and how much it can carry by weight (kilograms or pounds). For light materials like dry sand or topsoil, the truck bed fills up before reaching the weight limit — volume governs. For heavy materials like wet clay or rock, the truck reaches its weight limit before the bed is full — weight governs.
Many contractors estimate trips by volume alone, which works for light materials. But for heavy soils, this leads to overloaded trucks, which damages equipment, risks fines, and creates safety hazards. This calculator makes the weight check automatic, and the excavation cost factors guide helps you translate those hauling assumptions into disposal, access, and production impacts.
Suppose an excavation produces 80 yd³ of bank soil. The soil expands by a 1.25 bulking factor after digging, so the loose hauling volume is:
80 yd³ × 1.25 = 100 yd³ loose material
If a tandem dump truck can carry 14 yd³ by volume, the volume check is:
100 yd³ ÷ 14 yd³ per load = 7.14 loads, rounded up to 8 loads
If the loose soil weighs about 2,500 lb/yd³, the total material weight is 250,000 lb. With a 32,000 lb payload limit, the weight check is 7.81 loads, also rounded up to 8 loads. Because partial truck trips still require a full trip, the realistic hauling estimate is 8 dump truck loads.
| Truck type | Typical bed volume | Typical payload | Planning notes |
|---|---|---|---|
| Small dump or landscape truck | 3-6 yd³ | 6,000-12,000 lb | Good for tight access, but payload can govern quickly with wet soil, concrete, or rock. |
| Single axle dump truck | 7-10 yd³ | 18,000-24,000 lb | Common for residential excavation, topsoil, mulch, and smaller gravel deliveries. |
| Tandem axle dump truck | 10-14 yd³ | 25,000-32,000 lb | Often used for excavation hauling; heavy clay or stone may hit payload before the bed is full. |
| Tri-axle dump truck | 16-18 yd³ | 35,000-42,000 lb | Efficient for larger sites where access, turning radius, and local weight limits allow it. |
| Transfer or super dump | 20-25 yd³ | 45,000-53,000 lb | Best for high-volume hauling, subject to route restrictions, staging space, and axle limits. |
Confirm actual bed capacity, legal payload, axle configuration, and route limits with the truck owner or hauling contractor. Dense materials such as wet clay, broken concrete, asphalt, and rock often require extra trips even when the bed appears partly empty.
