Frequently Asked Questions
What is included in the monthly mortgage payment?
This calculator computes principal and interest only (P&I). Actual payments may also include property taxes, homeowners insurance, and PMI (Private Mortgage Insurance).
How does a lower interest rate affect my payment?
Even a 0.5% rate reduction can save hundreds per month. For a $300K loan, the difference between 6% and 6.5% is about $95/month or $34,200 over 30 years.
Should I choose a 15-year or 30-year term?
A 15-year term has higher monthly payments but significantly less total interest. Choose based on your budget and financial goals.
What is an amortization schedule?
It shows how each payment is split between principal and interest over the life of the loan. Early payments are mostly interest; later payments are mostly principal.
