5. Frequently Asked Questions (FAQ)

Q1: What's the difference between APR and interest rate?
A: APR includes both the interest rate and any additional fees or costs associated with the loan, providing a more comprehensive measure of borrowing costs.

Q2: Can this formula be used for any type of loan?
A: This formula works for fixed-rate amortizing loans, including mortgages, auto loans, and personal loans. It may not apply to interest-only loans or variable-rate loans.

Q3: How does loan term affect monthly payments?
A: Longer loan terms result in lower monthly payments but higher total interest costs over the life of the loan.

Q4: What if I make additional payments?
A: Additional payments reduce the principal balance faster, which can shorten the loan term and reduce total interest paid.

Q5: Are there any fees not included in this calculation?
A: This calculation includes only principal and interest. Additional costs like insurance, taxes, or origination fees may apply to actual loan payments.
