The question behind Refinance Calculator
Borrowers use this guide when a lower rate may or may not justify closing costs and a new term.
Compare current loan and refinance terms, monthly savings, closing costs, and break-even time. One useful application is to estimate refinance break-even months.
Refinance Calculator inputs and assumptions
The Refinance Calculator sample starts with Currency USD, Current loan balance 280000, Current annual interest rate 7 %, Current term remaining 300 months, New annual interest rate 6.25 %, New loan term 30 years. Replace it with values from one Refinance case, then verify Currency and Planned time before sale or next refinance against the source information before calculating.
Resetting to a longer term without checking total interest; check that each value belongs to the same Refinance Calculator period, unit, person, account, or scenario.
