What is the VinFast Total Cost of Ownership Calculator?
Buying an electric vehicle is more than a sticker price. The VinFast Total Cost of Ownership (TCO) calculator helps you estimate the real lifetime cost of owning a VinFast EV by combining the up-front purchase price with recurring expenses — insurance, maintenance and charging — across the years you plan to keep the car, then subtracting the money you expect to recover when you sell it. The result gives you a far more honest comparison between vehicles than purchase price alone.
How to use it
Enter the purchase price you paid (or expect to pay), the number of years you plan to own the vehicle, and your typical annual insurance, maintenance and charging costs. Finally, estimate the resale value at the end of that period. The calculator multiplies the combined annual costs by the number of years, adds the purchase price, and subtracts the resale value to show your total cost of ownership and the average cost per year.
The formula explained
The core equation is $$\text{TCO} = P + n \times (I + M + C) - R$$ where P is purchase price, n is the years of ownership, I is annual insurance, M is annual maintenance, C is annual charging cost, and R is resale value. The annual running cost \((I + M + C)\) is multiplied by the years owned because these expenses repeat each year.
Worked example
Suppose you buy a VinFast for $42,000 and keep it for 5 years. Annual insurance is $1,500, maintenance is $600 and charging is $700 — that's $2,800 per year, or $14,000 over five years. If you sell it for $18,000, your TCO is $$42{,}000 + 14{,}000 - 18{,}000 = 38{,}000$$ an average of $7,600 per year.
FAQ
Does this include financing interest? No — the model uses the cash purchase price. If you finance, add total interest paid into the purchase price field for a closer estimate.
What charging cost should I use? Estimate your annual mileage, divide by efficiency to get kWh, and multiply by your electricity rate. Home charging is usually far cheaper than public fast chargers.
Why subtract resale value? Because money you recover at sale offsets your ownership cost. A higher resale value lowers your effective TCO.
