Frequently Asked Questions

What is an amortization schedule?

An amortization schedule shows how each payment is split between principal and interest over the life of the loan. Early payments go mostly toward interest, while later payments pay down more principal. This calculator can generate a full amortization schedule.

How does the interest rate affect my payment?

Higher interest rates significantly increase both monthly payments and total interest paid. For example, on a $300,000 loan, a 1% rate increase can add $200+ to monthly payments and $70,000+ in total interest over 30 years.

What happens if I make extra payments?

Extra payments reduce your principal balance, which decreases total interest paid and can shorten your loan term. Even small additional payments can save thousands in interest. Specify that extra payments go toward principal.

Fixed vs. variable interest rate - which is better?

Fixed rates stay the same for the entire loan term, providing payment stability. Variable (adjustable) rates can start lower but may increase, raising your payment. Fixed rates are generally better for long-term loans when you want predictable payments.

Can I afford this loan?

Lenders typically recommend that debt payments (including this loan) don't exceed 36-43% of your gross monthly income. Use the debt-to-income ratio as a guideline, but also consider your other financial obligations and emergency savings.
