A visual breakdown shows exactly how much of each payment goes to principal versus interest over the life of the loan.

Frequently Asked Questions

What's included in the monthly payment?
The core payment is principal and interest (P&I), calculated from your loan amount, rate, and term. You can optionally add monthly property tax and insurance estimates to see your total housing cost.
What is PMI and when do I need it?
Private Mortgage Insurance is typically required when your down payment is less than 20% of the home price. This calculator doesn't include PMI, so factor in an extra $50–$200/mo if your down payment is below 20%.
How does the loan term affect my payment?
A 30-year term gives a lower monthly payment but much higher total interest. A 15-year term roughly doubles the monthly payment but can save tens of thousands in interest over the life of the loan.
