Frequently asked questions

How do I calculate my monthly mortgage payment?

Your monthly payment depends on the loan amount, interest rate, and loan term. Use the formula M = P[r(1+r)^n]/[(1+r)^n-1]. Our calculator also adds property tax, insurance, PMI, and HOA to show your true monthly cost.

What is PMI and when do I need it?

PMI (Private Mortgage Insurance) is required when your down payment is less than 20% of the home price. It typically costs 0.5%–1% of the loan amount annually and can be removed once you reach 20% equity.

What is a good mortgage rate in 2026?

Mortgage rates vary by lender, credit score, and loan type. As of 2026, 30-year fixed rates have ranged between 6%–7.5%. Use our calculator to see how different rates affect your monthly payment.

How much house can I afford?

A common guideline is the 28/36 rule: your mortgage payment should not exceed 28% of your gross monthly income, and total debt payments should not exceed 36%. Lenders also consider your credit score, down payment, and debt-to-income ratio.

What is an amortization schedule?

An amortization schedule shows how each monthly payment is split between principal and interest over the life of the loan. Early payments are mostly interest; later payments shift toward principal.
