Calculate Your Mortgage Loan Today

Understanding your mortgage payments is a crucial step in the home buying process. Our calculator helps you budget effectively, ensuring that your dream home in Tomales is within financial reach. It also aids in long-term financial planning by breaking down the costs associated with your loan.

Components of Your Mortgage Payment

When using our home loan calculator, consider the following components of your monthly payment, often referred to as PITI:

  • Principal (P): The portion of your payment that reduces the original loan amount.
  • Interest (I): The cost of borrowing the principal, based on your interest rate.
  • Taxes (T): Property taxes based on local rates in Tomales and Marin County.
  • Insurance (I): Homeowners insurance and potentially private mortgage insurance (PMI) if your down payment is less than 20%.

Mortgage Payment Formula

Use this formula to calculate your fixed-rate home loan payment (M) each month:
