The Role of APR and Note Rate

When using a mortgage estimator, it's crucial to understand the difference between the annual percentage rate💡 Definition:The total yearly cost of borrowing money, including interest and fees, expressed as a percentage. (APR) and the note rate. The APR includes both the interest rate and some fees, offering a broader view of loan costs. However, for basic payment calculations, the note rate—what's commonly advertised—is typically used. The formula for calculating your monthly payment is:

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

where (M) is the monthly payment, (P) is the loan amount, (r) is the monthly interest rate (annual rate ÷ 12), and (n) is the number of payments.

Real-World Examples and Scenarios

• Scenario 2: If the interest rate increases to 7.5%, the monthly payment would rise to $2,098.
• Scenario 3: For a 15-year loan at 6.5%, the monthly payment would be about $2,602.

These examples highlight how even a small change in the interest rate can significantly affect your monthly payments and the total interest paid over the life of the loan.
