How this math works
The tool uses the standard amortization formula lenders use. Your loan amount is the price minus the down payment, and the monthly payment is calculated so the loan reaches exactly zero at the end of the term. The chart shows the balance falling year by year.
Notice how slowly the balance drops in the early years. That is because early payments are mostly interest. It also shows why a 15 year loan, or extra principal payments on a 30 year loan, saves so much interest over time.
Common questions
Does this include taxes and insurance?
No. The payment shown covers principal and interest only. Property taxes, homeowners insurance, and possibly mortgage insurance and HOA dues come on top, often adding several hundred dollars a month.
What is PMI and when do I pay it?
Private mortgage insurance is usually required when your down payment is under 20 percent on a conventional loan. It typically costs 0.5 to 1.5 percent of the loan amount per year until you reach 20 percent equity.
Is a 15 year loan worth it?
A 15 year loan carries a higher monthly payment but a lower rate and dramatically less lifetime interest. Run both terms in the calculator and compare the totals before you decide.
