Does the monthly cost change? In this estimate, the mortgage payment stays level within each five-year term. Renewal payments are based on the regular scheduled amortization, while accelerated weekly and accelerated bi-weekly payments reduce the actual balance faster and shorten the payoff timeline. Months with an extra payment show higher mortgage cash flow. Within each term, mortgage interest generally goes down while principal—the part that pays off your mortgage—goes up. Once the mortgage is paid off, the entered ownership costs remain.

Principal is the part of each payment that reduces what you still owe. Mortgage interest is the cost of borrowing. Municipal taxes are converted from the annual amount to a monthly cost. Renewal payments use the entered rate and regular scheduled amortization. Accelerated payments are applied at the selected weekly or bi-weekly cadence to reduce the actual balance faster. All entered recurring ownership costs accumulate through each year; closing costs are counted once.
