  • Principal (P): The portion of your payment that goes toward repaying the original loan amount.
  • Interest (I): The cost of borrowing the principal, based on your loan’s interest rate.
  • Taxes (T): Local property taxes, which in Plumas County average around 0.8% of home value annually, according to the California Tax Foundation.
  • Insurance (I): Homeowners insurance and, if applicable, private mortgage insurance (PMI) for loans with less than 20% down payment.

Mortgage Payment Formula

Use this formula to calculate your fixed-rate home loan payment each month (denoted as "M" for mortgage):
