How extra principal changes mortgage payoff
Worked example
With $240,000 left at 5% and 25 years remaining, the estimated principal and interest payment is $1,403.02. Adding $200 per month reduces payoff to 236 months and saves $43,976.93 in interest.
The estimate finds the smallest monthly payment in cents that clears the principal within the remaining term, using monthly interest rounded to cents. It then compares that schedule with the same loan after extra principal payments.
Use this for a fully amortizing fixed-rate mortgage. Your statement may include taxes, insurance, or other charges on top of principal and interest. Check how your servicer applies extra payments and ask for an official payoff quote before closing the loan.
