Construction Material Truck Capacity Calculator
Convert a construction material requirement into practical vehicle loads. Compare full loads, the final partial load and unused truck capacity without mixing weight and volume units.
Material and truck inputs
Truck-load requirement
How truck-load quantities are calculated
The same arithmetic works for tonnes, cubic metres, bags or individual pieces as long as the material quantity and truck capacity use exactly the same unit.
Total loads = ceiling(material quantity ÷ effective capacity)
Full loads = floor(material quantity ÷ effective capacity)
Final partial = remainder after full loads
Worked example
A 240-tonne material requirement with 20 tonnes nominal capacity and a 95% loading factor has 19 tonnes effective capacity per load. The estimate is therefore 13 loads.
Why weight and volume must not be mixed
A 20-tonne truck capacity cannot be divided directly into a cubic-metre requirement. Convert the material quantity first or use a truck capacity expressed on the same basis.
Fleet size is different from total loads
Four trucks can perform the total trips in multiple cycles. They do not reduce the total number of material loads required.
Frequently Asked Questions
Can I use bags or pieces?
Yes, provided capacity is expressed in the same unit.
Why use an effective capacity?
To account for practical loading limitations.
Is the last load usually full?
Not necessarily; the remaining quantity becomes the partial load.
Does this calculate haul duration?
No.
