1. What is the Car Payment With Upside Down Trade?

This calculator determines your new car payment when trading in a vehicle with negative equity (owing more than the trade-in value). It accounts for rolling the negative equity into your new loan.

2. How Does the Calculator Work?

The calculator uses the standard auto loan formula with negative equity:

\[ payment = \frac{(loan\_amount + (outstanding\_loan - trade\_value)) \times r}{1 - (1 + r)^{-n}} \]

Where:

Explanation: The formula calculates the monthly payment for the combined amount of the new loan plus any negative equity from the trade-in.

3. Importance of Negative Equity Calculation

Details: Understanding the impact of negative equity helps buyers make informed decisions about vehicle purchases and avoid overextending financially.

4. Using the Calculator

Tips: Enter all amounts in USD, interest rate as APR (e.g., 5.25), and term in months (typically 24-84). Negative equity is automatically calculated when trade value is less than outstanding loan.

5. Frequently Asked Questions (FAQ)

Q1: What is negative equity?
A: When you owe more on your current loan than the vehicle is worth, the difference is negative equity (or being "upside down").

Q2: How does negative equity affect my new loan?
A: The negative amount gets added to your new loan, increasing both your principal and monthly payment.

Q3: What's a typical auto loan interest rate?
A: Rates vary (3-10% APR) based on credit score, loan term, and market conditions (as of 2023).

Q4: Should I roll negative equity into a new loan?
A: Generally not recommended as it increases debt, but sometimes unavoidable. Consider alternatives like paying the difference.

Q5: How can I avoid negative equity?
A: Make larger down payments, choose shorter loan terms, and avoid long loans on rapidly depreciating vehicles.
