About Newfi’s IO Mortgage Calculator

Newfi is making it easier for people to see what mortgage payments they might be responsible for if they have a 40-year Interest-Only loan.

A highly respected Independent Mortgage Banker, Newfi uses this proprietary mortgage loan product to help borrowers that are looking to pay only the interest for an initial term of their home loans.

This Interest-Only Mortgage Calculator is made specifically for people borrowing for a home purchase or a home refinance using the innovative 40-year Interest-Only mortgage loan.

This benefits new homeowners who might be getting used to a mortgage payment, or using savings for furnishing the home, or taking care of other costs of the first years of home ownership.

Some borrowers look to the 40-Year IO to compare their current mortgage payment to one where they would just be responsible for the interest.

A “Cash-Out” IO mortgage loan would offer Interest-Only payments. It makes borrowing money even cheaper (think of it like a bank account) and allows you to make the value in your home work for you.

We know that mortgage rates are on the rise after being dropped to historic lows as a means of stimulating the economy during the recent housing crisis due to the pandemic. As rates rise, Newfi offers this product with a 40-year term, and only reliable interest-only payments over a starting period.

Simply enter the start date, loan amount and an interest rate into the calculator, along with the 40-year term and 10-year IO period, and see what estimated payments come up. The numbers are also plotted on an easy-to-reference chart.
