The True Monthly Cost of Car Ownership
Many buyers focus only on the monthly loan payment, overlooking insurance, fuel, parking, and maintenance — which often add 50–100% on top. Understanding the full picture before buying helps you choose the right vehicle for your budget.
This calculator uses the standard amortizing (equal monthly payment) formula to compute your loan payment, then sums all operating costs to show your true monthly and annual outlay.
Electric vehicles typically have lower fuel and maintenance costs but may have higher insurance premiums. Run the numbers for both gas and EV options before deciding.
