1. What is the Car Loan Settlement Formula?

The car loan settlement formula calculates the remaining balance on a car loan after a certain number of payments have been made. It accounts for the principal amount, interest rate, total loan term, and payments already made.

2. How Does the Calculator Work?

The calculator uses the car loan settlement formula:

\[ Payoff = P \times \frac{(1 + r)^n - (1 + r)^k}{(1 + r)^n - 1} \]

Where:

\( P \) — Principal loan amount (USD)
\( r \) — Monthly interest rate (annual rate ÷ 12)
\( n \) — Total loan term (months)
\( k \) — Number of payments already made (months)
\( Payoff \) — Remaining balance (USD)

Explanation: The formula calculates how much of the principal remains unpaid after k payments, accounting for the interest that would have been paid over the remaining term.

3. Importance of Loan Settlement Calculation

Details: Knowing your payoff amount is crucial when considering early loan repayment, refinancing, or selling your vehicle before the loan term ends.

4. Using the Calculator

Tips: Enter the original loan amount, annual interest rate (typically 5-7%), total loan term in months, and number of payments already made. All values must be valid (principal > 0, rate > 0, term > 0, payments made ≤ term).

5. Frequently Asked Questions (FAQ)

Q1: Why is my payoff amount different from my remaining principal?
A: The payoff includes both remaining principal and any interest that would accrue over the remaining loan term.

Q2: Does making extra payments reduce my payoff amount?
A: Yes, extra payments reduce principal faster, which decreases both remaining principal and future interest.

Q3: How accurate is this calculator?
A: It provides a close estimate, but your lender's exact payoff amount may include small fees or slightly different calculation methods.

Q4: Can I use this for other types of loans?
A: This formula works best for fixed-rate installment loans like auto loans. It may not be accurate for adjustable-rate or interest-only loans.

Q5: Why does the payoff amount change daily?
A: Interest accrues daily on most loans, so the exact payoff amount depends on when you make the payment.
