E.g., 15 for 15%. Cars often depreciate ~20% in Year 1, then less.
Understanding Your Results & Key Considerations:
Positive Equity: This is your goal. It means your car is worth more than your outstanding loan balance. The higher the positive equity, the more you can use towards a down payment on your next car.
Negative Equity (Upside Down): This means you owe more than the car is worth. Trading in a car with negative equity often means rolling that debt into your next car loan, which is generally not advisable.
Depreciation: The "Estimated Annual Depreciation" is an average. Actual depreciation varies significantly by car make, model, condition, mileage, and market demand. New cars depreciate fastest in the first 1-3 years. Research your specific car's typical depreciation curve for more accuracy.
Loan Amortization: In the early stages of your loan, a larger portion of your monthly payment goes towards interest. As you pay down the loan, more goes towards the principal.
"Sweet Spot": Many find a good time to trade is when they have decent positive equity, often between years 3-5 for a typical 5-7 year loan, depending on the car and loan terms. This is often before major maintenance might be due or warranties expire.
Warranty Expiration: Trading in before your manufacturer's warranty expires can increase its appeal and value.
Market Conditions: A strong used car market can increase your trade-in value.
Total Cost of Ownership: Consider not just equity, but also upcoming maintenance, insurance costs, and fuel efficiency if you're thinking of switching.
