Our calculator helps you quickly determine if refinancing your mortgage makes financial sense. By entering your current loan details and your potential new loan terms, you can see how much money you could save in interest, how much faster you could pay off your loan by applying extra payments, and what your effective interest rate would be with those extra payments applied. The interactive graph visually compares your current loan payoff timeline against your new loan options, making it easier to make an informed decision about refinancing.
