Truck & Fleet Tools & Calculators
Free, practical tools for owner-operators and fleets — check towing capacity, decode a tire size, work out MPG and fuel cost, schedule preventive maintenance, ballpark commercial insurance, project depreciation, and price a truck loan.
Towing Capacity Checker
Enter GCWR, curb weight, payload, and occupants to see how much your truck can safely tow, the margin against your trailer, and 10–15% tongue-weight guidance — with a clear pass or fail
Tire Size Calculator
Decode a commercial, P-metric, or LT tire size into overall diameter, section width, sidewall, circumference, and revolutions per mile — and compare two sizes for the speedometer and gearing effect
MPG / Fuel Economy Calculator
Turn distance and fuel used into MPG, L/100km, and km/L for a diesel or gasoline truck, and add a fuel price to see exactly what each mile and kilometre costs
Fuel Cost Calculator
Estimate diesel cost per trip, month, and year from distance, MPG, and price — then switch on fleet mode to multiply the total across every truck you run
Truck Maintenance Scheduler
Generate a preventive-maintenance schedule from your odometer and annual mileage — oil, DPF, brakes, transmission, tires, and the annual DOT inspection — ranked by how soon each is due
Commercial Truck Insurance Estimator
Get a transparent ballpark for annual commercial-truck insurance from value, radius, cargo, experience, and coverage — with a factor breakdown and a low–high range (a planning estimate, not a quote)
Truck Depreciation Calculator
Project how a truck or machine loses value — straight-line or accelerated declining-balance — from price, salvage, and useful life, with a year-by-year book value table
Truck Loan Calculator
Price a truck or equipment loan from price, down payment, trade-in, APR, and term — monthly payment, total interest, total cost, and an amortization snapshot
