Results are estimates based on user inputs and do not represent loan terms, APR, or a financing offer. Pre-filled values are illustrative examples, not available or quoted rates. Actual terms depend on credit, property, program, and underwriting. Every result applies to the entered planning scenario, not an observation period or local market statistic. Replace price, tax, insurance and fee allowances with dated, property-specific figures. Missing inputs are not assumed to be zero.

Frequently asked questions

What is an amortization schedule?
A month-by-month table showing exactly how each scheduled payment splits between interest and principal, and what the remaining loan balance is after each payment. Early payments are mostly interest; later payments are mostly principal.
Why is most of my early payment interest?
Interest is charged on the remaining balance. In the first year the balance is near its peak, so most of the payment covers interest. As the balance drops, the interest portion drops and the principal portion grows.
Does adding a little extra principal really matter?
Yes. Because interest compounds on the balance, even a small recurring extra each month can knock years off the loan and tens of thousands of dollars off total interest. Use the Prepayment Calculator to quantify it.
Is the schedule exact?
The math uses the standard amortization formula. Your real statement may differ by a few dollars per month due to rounding, leap-year interest rules, or how your servicer applies partial payments.
