Vehicle EconomicsCost of Owning a Car for 3 Years
A fixed, 36-month ownership scenario, the horizon that matches a typical short auto loan term.
Why this comes up
"What does this car cost me over 3 years" is a specific, common question, especially for anyone matching their ownership horizon to a typical 36-month loan term. The open-horizon True Cost of Car Ownership hub answers any horizon; this page is the direct answer to the 3-year question specifically, with its own worked example at that fixed length.
How we calculated this
We sum every material ownership cost, depreciation, financing interest, fuel, insurance, maintenance, repairs, and registration, over exactly 36 months using your own annual figures, then show the total, annual, and monthly equivalents.
Worked example, using this page's own defaults: over 3 years, depreciation costs $6,600, financing interest $2,700, and combined insurance, maintenance, repairs, and registration add roughly $7,440, before fuel. Run the calculator above to see the exact total with your own numbers.
What this means
- If your loan runs longer than 36 months, you will still owe a remaining balance at the end of this window, this engine reports the cost incurred, not an end-of-term payoff.
- Comparing this figure against Cost of Owning a Car for 5 Years shows how per-year cost tends to fall as a longer horizon spreads fixed costs further.
- This is a planning estimate from your own assumptions, not a forecast or guarantee.
Limitations
Depreciation, financing interest, and every operating cost are your own flat annual estimates held constant across the 3 years; real costs vary year to year. See Methodology.
Methodology
This engine reuses Vehicle Economics' ownership total cost model (every ownership cost summed over your horizon) and fuel and charging cost model, with the horizon fixed at 3 years. See Methodology for the full detail.
