Frequently Asked Questions

What is PITI in a mortgage payment?

PITI stands for Principal, Interest, Taxes, and Insurance — the four components of a typical monthly mortgage payment. Lenders use total PITI to qualify you, not just principal and interest.

How accurate is this mortgage calculator?

It uses the standard amortization formula and 2026 PITI assumptions. Actual rates and escrow amounts vary by lender, credit score, and location.

How much can extra payments save me?

Even an extra $100/month on a 30-year loan can shave 4-6 years off your term and save tens of thousands in interest. Use the extra payment field to see your exact savings.

When does refinancing make sense?

Refinancing is typically worth it when you can lower your rate by 0.75%+ and stay in the home long enough to recover closing costs (usually 2-3 years).

What credit score do I need for the best mortgage rate?

A score of 740+ typically qualifies you for the best mortgage rates. Scores between 620-739 still qualify but at higher rates. Each 20-point score improvement can save 0.1-0.3% in rate, which equals thousands over the loan term.

How much should I put down on a house?

20% down avoids PMI (saving $100-$300/month) and gets better rates. But 3-5% down programs exist for first-time buyers. Our calculator shows exactly how PMI changes your payment at different down payment percentages.
