Explanation: The formula accounts for compound interest over the life of the loan, ensuring each payment covers both interest and principal.
Details: Understanding your monthly payment helps with budgeting and comparing loan offers. It also shows the true cost of borrowing through total interest calculations.

Q1: What's the difference between APR and interest rate?
A: APR includes both interest rate and any loan fees, giving a more complete picture of borrowing costs.
Q2: How can I reduce my total interest paid?
A: Make larger payments when possible, choose a shorter loan term, or negotiate a lower interest rate.
Q3: Why does my payment stay the same but principal/interest ratio changes?
A: Early payments are mostly interest; as principal decreases, less interest accrues each month.
Q4: Are there loans with different payment structures?
A: Yes, some loans have interest-only periods or balloon payments, but this calculator assumes standard amortizing loans.
Q5: How accurate is this calculator?
A: It provides precise calculations for fixed-rate loans, but actual payments may vary slightly due to rounding or lender-specific policies.
