Frequently asked
About this calculator.
How is a monthly mortgage payment calculated?
Monthly principal and interest is calculated using M = P · r(1+r)^n / ((1+r)^n − 1), where P is the loan amount, r is the monthly interest rate, and n is the total number of payments. Your total monthly payment also includes 1/12 of annual property taxes, 1/12 of annual home insurance, monthly HOA dues, and PMI if your down payment is less than 20%.
What is an amortization schedule?
An amortization schedule is a year-by-year (or month-by-month) table showing how each payment is split between principal and interest. Early in the loan, most of each payment goes to interest; toward the end, most goes to principal. The schedule below shows your projected balance at the end of every year, and how much equity you have built.
What is included in PITI?
PITI stands for Principal, Interest, Taxes, and Insurance — the four core components of most monthly mortgage payments. The breakdown panel here separates each one and adds HOA dues and PMI if you have entered them.
Are interest-only loans a good idea?
Interest-only loans keep the monthly payment lower but build no equity during the IO period. They make sense for short-hold scenarios (planning to sell or refinance within 5–10 years) or when you have variable income and want flexibility. They are not appropriate for borrowers who plan to amortize a loan to payoff. We have IO programs available — call (707) 583-3666 to discuss whether one fits.
How accurate is this calculator?
The principal-and-interest math is exact. Property tax and insurance numbers depend on your county, the home, and your insurer — defaults are illustrative. PMI rates vary by credit score and LTV; the input here is yours to set. For a binding rate quote with real PMI pricing, call us — no credit pull needed for the initial scenario.
