A reverse mortgage calculatoris an online tool used to determine the payout one can expect to receive from this financial product. In addition to payouts, many calculators will also compute a borrower's expected closing costs, interest rate, and mortgage insurance premiums. These tools are typically used to help borrowers determine whether they would be eligible for a loan, as well as how much they would qualify for should they choose to apply. How to Use a Reverse Mortgage Calculator To use a reverse mortgage calculator, borrowers will input their age, the estimated value of their home, zip code, and the remaining balance of their mortgage loan if applicable. The calculator will use this information to determine whether the borrower would qualify for a loan based on his or her age and amount of equity. Borrowers who would qualify for a reverse mortgage will be shown a few different options. In many cases, consumers will be shown how much they would qualify for through a fixed-rate HECM Standard, an adjustable-rate HECM Standard, and an HECM Saver. Consumers will also be shown how much they can expect to receive if they choose to accept their money in a lump sum, line of credit, or receive monthly payments.
