Car Loan & Opportunity Cost Calculator
Analyze the true cost of a car loan, including interest and lost investment gains.
This calculator helps you understand the total lifetime cost of your auto loan. Beyond the monthly payment, it's crucial to see the total interest you'll pay. A lower interest rate or a shorter loan term can save you thousands.
The most powerful feature here is the "Opportunity Cost" calculation. It shows you how much money you could have had if, instead of making car payments, you had invested that same amount of money into the stock market with a modest annual return. This reveals the true financial impact of taking on a car loan versus investing for your future.
Use the Compare Scenarios button below to model two different loan strategies side-by-side to see how each choice impacts your monthly payment and total cost over time.
