About the Mortgage Calculator

This mortgage calculator helps you estimate your total monthly payment including principal, interest, taxes, insurance, PMI, and HOA fees. Understanding the full cost of homeownership is essential for budgeting and choosing the right home loan. It shows a complete amortization schedule, bi-weekly payment comparison, and how extra payments can save thousands in interest and shorten your loan term.

How to Use This Calculator

  1. Enter the home price, down payment (as a percentage or dollar amount), interest rate, and loan term.
  2. Toggle optional costs like property taxes, insurance, PMI, HOA, and other expenses to see the true monthly payment.
  3. Open Advanced Options to add extra payments, annual cost increases, or compare bi-weekly savings.

The Formula

This calculator uses the standard amortization formula for the principal and interest portion, then adds monthly equivalents of taxes, insurance, and other costs.

M = P × [r(1+r)^n] / [(1+r)^n - 1] + (Tax + Ins + PMI + HOA + Other) / 12

Frequently Asked Questions

What factors affect my mortgage payment?

Your monthly mortgage payment is determined by the loan amount, interest rate, loan term, property taxes, homeowners insurance, PMI, and HOA fees. A longer term lowers monthly payments but increases total interest paid.

Should I choose a 15-year or 30-year mortgage?

A 15-year mortgage has higher monthly payments but significantly less total interest. A 30-year mortgage offers lower monthly payments, making homeownership more accessible.

How does my credit score affect my mortgage rate?

Your credit score directly impacts the interest rate you qualify for. Borrowers with scores above 740 typically receive the lowest rates, while lower scores may result in higher rates and additional PMI requirements.

What is PMI and when is it required?

Private Mortgage Insurance (PMI) is required on conventional loans when your down payment is less than 20%. It protects the lender and typically costs 0.3% to 1.5% of the loan amount annually. PMI can be removed once you reach 20% equity.

Can I make extra payments to pay off my mortgage faster?

Yes, making extra principal payments can significantly reduce your loan term and total interest. Even one extra payment per year can shave years off a 30-year mortgage and save thousands in interest.

What is the difference between fixed-rate and adjustable-rate mortgages?

Fixed-rate mortgages lock in your interest rate for the entire loan term, providing predictable payments. Adjustable-rate mortgages (ARMs) start with a lower rate that adjusts periodically based on market conditions.
