Q1: Why does early interest seem higher?

Q2: How can I pay less interest?
A: Make extra principal payments or choose a shorter loan term to reduce total interest paid.
Q3: What's the difference between rate and APR?
A: The rate is the interest charged, while APR includes fees and other loan costs for a true cost comparison.
Q4: Can I see the effect of extra payments?
A: This version shows the standard schedule. For extra payments, use our Advanced Mortgage Calculator.
Q5: Why does my last payment sometimes differ?
A: Final payments may adjust slightly due to rounding in the amortization calculations.
