Vehicle Expenses Meaning, Cost Per KM & Truck Mileage Guide
Last Updated: October 2026 | Fleet Costing & Transport Accounting
Vehicle expenses (also referred to in business accounting as automobile expenses or vehicle running expenses) encompass every direct cost required to operate, maintain, fuel, and license commercial trucks and fleet vehicles. Tracking expenses on a per-vehicle basis—rather than as a general company lump sum—is the key to identifying loss-making trucks and improving profit margins.
Definition
Vehicle Expenses: Direct operational and capital expenditures attributed to a specific vehicle asset, including diesel fuel, Fastag toll, driver trip batta, tyre wear, preventive maintenance, insurance, permits, and financing depreciation.
Fixed vs Running Vehicle Expenses
To accurately price freight and bid on transport contracts, operators must divide vehicle costs into fixed and variable categories:
| Cost Category | Expense Type | Examples & Line Items | How to Control in TruckBill |
|---|---|---|---|
| Fixed Costs (Standing Charges) | Time-based (Incurred even if truck stands idle) | Truck loan EMI, annual insurance premium, national permit fees, fitness certificate, road tax, GPS subscriptions, driver retainer salary. | Automated document renewal alerts prevent RTO penalties; amortized daily cost allocated to trip profit & loss. |
| Running Costs (Variable Charges) | Distance-based (Incurred only when wheels roll) | Diesel / fuel, DEF (AdBlue), Fastag highway tolls, driver trip batta (food allowance), loading/unloading hamali, greasing, oil top-ups, tyre wear. | Fuel slip verification, digital trip sheets, automated mileage discrepancy alerts. |
| Maintenance & Repairs | Periodic & Breakdown | Engine overhaul, brake shoe replacement, leaf spring repair, clutch plate renewal, spare parts inventory. | Service reminders based on odometer kilometers; workshop job-card tracking. |
How to Calculate Transport Cost Per KM
Knowing your exact cost per kilometer (CPK) ensures you never accept a load below your break-even threshold:
Cost Per KM Formula:
Cost Per KM = (Running Trip Expenses + Allocated Fixed Costs) / Total Kilometers Driven
Worked Example: A 10-wheeler truck completes a 1,200 KM round trip between Jaipur and Kandla Port:
- Diesel: 300 Liters @ ₹90/L = ₹27,000 (Running cost = ₹22.50 / km)
- Fastag Tolls: ₹3,600 (Running cost = ₹3.00 / km)
- Driver Batta & Hamali: ₹2,400 (Running cost = ₹2.00 / km)
- Tyre & Maintenance Reserve: ₹2.50 / km = ₹3,000
- Allocated Daily Fixed Cost (EMI/Insurance/Tax for 3 days): ₹3,600 (Fixed cost = ₹3.00 / km)
- Total Trip Cost: ₹39,600
- Total Cost Per KM: ₹39,600 / 1,200 KM = ₹33.00 per KM
Average Mileage of Trucks in India (Km per Liter)
Fuel represents 55% to 65% of all vehicle operating expenses in India. Monitoring mileage per liter ensures drivers aren't siphoning diesel or running poorly tuned engines:
| Vehicle Category | Typical Payload / GVW | Axles / Wheels | Expected Loaded Mileage | Expected Empty (Return) Mileage |
|---|---|---|---|---|
| Light Commercial (LCV) | 1.5 Ton to 3.5 Ton (Pickup/Boloero) | 4 Wheels | 11.0 – 13.5 Km/L | 13.0 – 15.0 Km/L |
| Intermediate (ICV) | 7.0 Ton to 11.0 Ton | 6 Wheels | 6.5 – 8.0 Km/L | 8.0 – 9.5 Km/L |
| Medium Freight (MCV) | 16.0 Ton (1613 / 1616) | 6 Wheels | 4.5 – 5.5 Km/L | 5.5 – 6.5 Km/L |
| Heavy Goods (HCV) | 25.0 Ton to 28.0 Ton (2518 / 2820) | 10 Wheels | 3.5 – 4.2 Km/L | 4.5 – 5.2 Km/L |
| Multi-Axle Truck (MAV) | 35.0 Ton to 42.0 Ton (3518 / 4220) | 12 / 14 Wheels | 3.0 – 3.8 Km/L | 3.8 – 4.5 Km/L |
| Tractor-Trailer | 46.0 Ton to 55.0 Ton (4923 / 5525) | 18 – 22 Wheels | 2.4 – 3.0 Km/L | 3.2 – 3.8 Km/L |
Diesel Cards & FASTag Management for Fleets
Managing fuel and highway toll expenses through cash leads to pilferage and fake vouchers. Modern Indian transport fleets utilize corporate fuel and toll management platforms:
Diesel Cards for Trucks in India
Programs like HPCL DriveTrack Plus, BPCL SmartFleet, and IOCL XTRAPOWER provide RFID smart cards linked to specific vehicle registration numbers.
- Drivers can only fill diesel for the assigned truck registration.
- Daily transaction logs sync directly into TruckBill to reconcile trip sheets.
- Earn 0.5% - 1.5% cashback loyalty points on high diesel volume.
FASTag Fleet Management System
Automated toll management links vehicle FASTags to a centralized corporate wallet (IDFC, ICICI, SBI, Axis Bank).
- Automatic low-balance alerts prevent trucks getting stuck at highway toll plazas.
- Toll deduction timestamps verify truck transit speeds and actual routes taken.
- No manual cash reimbursement required for toll slips.
