Refinancing a loan means replacing an existing loan with a new loan that has different terms. People refinance mortgages, student loans, auto loans, and personal loans to try to lower interest, reduce monthly payments, shorten the payoff time, or change from a variable rate to a fixed rate. The main goal is not just to get a new payment, but to improve the total financial outcome.
A good refinance decision compares both the short-term cash flow and the long-term cost.
Key Facts
- Refinancing means old loan paid off by new loan.
- Monthly payment depends on principal, interest rate, and loan term.
- Lower monthly payment can increase total interest if the loan term is extended.
- Interest for one month can be estimated as monthly interest = balance x annual rate / 12.
- Break-even time = refinance closing costs / monthly savings.
- Total loan cost = total of all payments + fees.
Vocabulary
- Refinancing
- Refinancing is the process of replacing an existing loan with a new loan, usually with different interest rates, payments, or terms.
- Interest rate
- The interest rate is the percentage charged by the lender for borrowing money.
- Loan term
- The loan term is the length of time over which the borrower agrees to repay the loan.
- Closing costs
- Closing costs are fees paid to complete the new loan, such as application fees, appraisal fees, or lender charges.
- Break-even point
- The break-even point is the time it takes for monthly savings from refinancing to equal the upfront costs.
Common Mistakes to Avoid
- Comparing only the monthly payment is wrong because a lower payment can come from stretching the loan over more years, which may increase total interest.
- Ignoring closing costs is wrong because refinance fees can cancel out the savings from a lower interest rate.
- Assuming a lower interest rate always saves money is wrong because the new loan term, fees, and remaining time on the old loan all affect the total cost.
- Refinancing too often is wrong because repeated fees and new loan terms can reduce or eliminate the financial benefit.
Practice Questions
- 1 A borrower can refinance and lower the monthly payment from 1,080, but closing costs are $2,400. What is the break-even time in months?
- 2 A loan balance is $180,000 with an annual interest rate of 6%. Estimate the interest charged for one month using monthly interest = balance x annual rate / 12.
- 3 A borrower is offered a refinance that lowers the monthly payment but adds 8 years to the repayment term. Explain why this might or might not be a good financial choice.
