1. What is the Bankrate Mortgage Rate Formula?

The Bankrate Mortgage Rate formula calculates the annual interest rate (r) for a loan given the monthly payment (PMT), number of payments (n), principal amount (P), and time in years (t). This helps borrowers understand their effective interest rate.

2. How Does the Calculator Work?

The calculator uses the Bankrate formula:

Where:

• \( r \) — Annual interest rate (decimal)
• \( PMT \) — Monthly payment amount (USD)
• \( n \) — Number of monthly payments (unitless)
• \( P \) — Principal loan amount (USD)
• \( t \) — Time in years (unitless)

Explanation: The formula calculates the effective annual interest rate by comparing total payments to principal over time.

3. Importance of Interest Rate Calculation

Details: Understanding your effective interest rate helps compare loan offers, plan repayments, and make informed borrowing decisions.

4. Using the Calculator

Tips: Enter all values accurately - monthly payment in USD, number of payments as whole months, principal in USD, and time in years.
