The total material volume to haul.

Use the cubic-yard result from a materials calculator like Gravel Driveway, Topsoil, or Concrete.

The hauling capacity of the truck being used.

Confirm the specific truck's rated capacity with your hauler or rental yard — capacities vary by truck configuration, and are quoted in cubic yards in North America and in cubic metres in metric markets.

Truck loads needed

5 x 12 yd³ loads

Medium confidence

Trucks are also limited by legal weight, not just volume — dense materials like gravel or wet soil may reach a truck's weight limit before filling its full volume capacity, requiring more, partial loads.

Then change the inputs to see how far the answer moves.

How this was calculated

Formula source(s)

  • Truck loads needed = total volume / truck bed capacity, rounded up — beds are quoted at 10-14 cubic yards in North America and at 8-12 m³ in metric markets, so the count is worked in whichever measure the hauler quotes rather than converted between them

Confidence note: Trucks are also limited by legal weight, not just volume — dense materials like gravel or wet soil may reach a truck's weight limit before filling its full volume capacity, requiring more, partial loads.

What this calculation does not cover

  • This counts volume only. It does not check payload, axle loading or gross vehicle weight, and a body filled with gravel, sand, wet clay or broken concrete normally reaches its legal weight limit before it is full — so dense material takes more trips than the volume count shows. It is not a legal load check; what the truck may legally carry is the hauler's call.
  • The figure you enter is treated as loose, as-loaded volume. Excavated soil and demolition debris swell once they are dug out, and delivered fill loses volume once it is compacted in place, so a bank (in-ground) or compacted-in-place quantity entered here undercounts loads. Convert to a loose volume before using this.
  • The three bed sizes are generic fleet sizes, not your truck. Rated capacity moves with body length, sideboard height and whether the quoted figure is struck (level) or heaped, and liners, tailgate gear and a worn body all change what actually goes in. Confirm the number with the hauler or rental yard.
  • Nothing here covers getting the truck to the material. Site access and turning room, overhead clearance, tipping space, posted road and bridge weight limits, seasonal load restrictions and permits all change how many trips are actually possible, and none of them are modelled.
  • One material, one truck type, and no cost. Loads that cannot be mixed — segregated waste streams, separate stockpiles — need their own counts, and haulage rates, tipping fees and disposal charges (often billed by weight or per ticket rather than per load) sit outside this calculation.

Most jobs need more than one number. Add the calculators you need next and they open right here, underneath this one — your figures stay on screen and nothing is lost to a page change.

Now that you have the number

These guides cover the work this quantity is for — the first ones run this calculator inside the section that raises the question.

  • A rising river and one working day: setting the line and the height, turning that into a bag count, and turning the bag count into loads of sand.

  • A treed lot bills twice: once for the brush and stumps it makes, and again at the scale house, where soil on a root ball changes the rate you pay.

  • A knotweed dig is measured from inspection pits, not off a drawing — and land, not price, decides between a lined cell, a cap and a licensed gate.

Still deciding? Barrowing vs Machine Haulage — the factors that actually differ, with no invented prices.

How to calculate dump truck load in 3 steps

  1. Total VolumeThe total material volume to haul.
  2. Truck Bed CapacityThe hauling capacity of the truck being used.
  3. Truck loads neededThe tool computes the truck loads needed from those figures and shows the formula, its sources, and a confidence rating alongside it.

Frequently asked questions

Why might a truck not actually carry its full rated volume?
Dense materials (gravel, wet soil, sand) can hit the truck's legal weight limit before filling the bed's volume capacity — for heavy materials, check with your hauler whether volume or weight is the binding constraint for a full load.
Should I order slightly more than the exact volume needed?
Many suppliers deliver full or half loads rather than precise custom volumes — check with your specific supplier on minimum order increments, and consider whether a small overage is worth avoiding an extra delivery trip.
Does this apply to both delivery and haul-away (like excavation spoil)?
Yes — the same load-count math applies whether you're receiving material (like gravel or mulch) or removing it (like excavated soil or debris).
Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction.
