How to use

This tool helps logistics businesses or regular drivers calculate the true running cost of a vehicle per kilometer. First, input your 'Total Fuel Cost' and the 'Total Distance' driven over a specific period. Then, add fixed and variable expenses like 'Maintenance Cost', 'Insurance', and 'Tolls & Parking'. The calculator sums up all these expenses and divides them by the total distance to give you a clear Cost per Km. This metric is crucial for setting delivery pricing, managing fleet budgets, or just understanding your personal commuting expenses.

How it's calculated

Total Annual Cost

annual_depreciation + annual_insurance + annual_maintenance + annual_fuel_cost

Total yearly cost of owning and operating the vehicle

Cost per km

(annual_depreciation + annual_insurance + annual_maintenance + annual_fuel_cost) / annual_km

True cost for every kilometre you drive

Cost per Month

(annual_depreciation + annual_insurance + annual_maintenance + annual_fuel_cost) / 12

Average monthly cost of owning the vehicle

Examples

Mid-range car: 15M dep + 5M ins + 3M maint + 18M fuel, 15,000 km/yr

  • Annual Distance Driven:15,000
  • Annual Fuel Cost:18,000,000
  • Annual Insurance:5,000,000
  • Annual Maintenance:3,000,000
  • Annual Depreciation:15,000,000

Result

  • total_cost:6,500,000
  • Cost per km:3,250₫/km

If you drive 2000 km, spending 4,000,000 VND on fuel, 1,000,000 VND on maintenance, 500,000 VND on insurance, and 1,000,000 VND on tolls, your total cost is 6,500,000 VND. This breaks down to an operational cost of 3,250 VND per km.

Motorbike scenario: 3M dep + 0.5M ins + 1.5M maint + 5M fuel, 10,000 km/yr

  • Annual Distance Driven:10,000
  • Annual Fuel Cost:5,000,000
  • Annual Insurance:500,000
  • Annual Maintenance:1,500,000
  • Annual Depreciation:3,000,000

Result

  • Cost per km:1,000
  • Cost per Month:833,333
  • Total Annual Cost:10,000,000

This motorbike costs 1,000₫ per km to operate — on the lower end for Vietnamese vehicles. At 10,000 km/year, the total cost of 10 million₫ is roughly the annual fuel bill for a car. Tracking this monthly helps justify fuel, maintenance, and insurance expenses for tax purposes.

Frequently Asked Questions

What is the true cost of car ownership in Vietnam?

Beyond the purchase price, owning a car in Vietnam involves annual depreciation (typically 10–20% of value), compulsory and voluntary insurance (3–8 million VND/year), maintenance and registration fees (2–5 million VND/year), and fuel. For a mid-range car driven 15,000 km/year, the true cost is often 2,500–4,000 VND per kilometre.

How much does car depreciation cost per year in Vietnam?

New cars in Vietnam typically depreciate 15–25% in the first year and 10–15% in subsequent years. A 500 million VND car may lose 75–125 million VND in value in year one. Luxury and imported vehicles depreciate faster due to high import taxes making resale values lower.

Is it cheaper to own a car or use ride-hailing in Vietnam?

For most urban residents driving under 10,000 km/year, ride-hailing (Grab, Be) is often cheaper when you factor in the true cost per km of ownership. Car ownership becomes more economical above 15,000–20,000 km/year, especially for families or those with regular intercity travel.

Should I include vehicle depreciation in my calculation?

Yes, for a completely accurate true cost of ownership, vehicle depreciation should be factored into your 'Maintenance/Other' costs. Most fleets amortize this over 5-7 years.
