Take the guesswork out of your trucking rates with Dump Truck Math. Our simple, easy-to-use calculators put all of your routine calculations conveniently at your fingertips. Estimators, truck owners, and project foremen alike can benefit from our three basic worksheets: Rate per Ton or Cubic Yard (CY): Convert your hourly rate into a tonnage or CY rate that factors in your tolls and travel time, as well as loading and unloading times. Trucks Needed: You know how long it takes to load each truck and you know how long the round trip will take. How many trucks will you need? Haul Difference: What's the per ton or per CY cost difference between two possible dump or load sites? Let Dump Truck Math help you get the job done on time and under budget.
