1. What is the Refinance Car Loan Calculator?

This calculator helps determine monthly payments for refinanced car loans using the standard loan payment formula. It's based on NerdWallet's platform approach where rates vary by credit score.

2. How Does the Calculator Work?

The calculator uses the loan payment formula:

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

Where:

\( P \) — Principal loan amount (USD)
\( r \) — Monthly interest rate (annual rate ÷ 12, in decimal)
\( n \) — Number of monthly payments (term in months)
\( PMT \) — Monthly payment amount (USD)

Explanation: The formula accounts for both principal and interest payments over the loan term.

3. Importance of Loan Payment Calculation

Details: Accurate payment calculation helps borrowers understand affordability, compare loan offers, and plan their budgets when refinancing auto loans.

4. Using the Calculator

Tips: Enter principal amount in USD, annual interest rate in percentage, and loan term in months. All values must be positive numbers.
