Refinancing trade-offs

A lower interest rate cuts the interest part of every payment, but refinancing has closing costs: lender fees, appraisal, title and sometimes points. Until the monthly savings add up to those costs, you are behind.

Resetting to a new 30-year term lowers the payment but stretches the debt out. If you have 25 years left, a new 30-year loan adds 5 years of payments. The true breakeven and lifetime interest figures make that trade-off visible.

Refinance FAQ

How is the refinance breakeven calculated?

Simple breakeven = closing costs / monthly payment savings. With $6,000 of costs and $300 a month saved, it takes 20 months.

Why is there a second, "true" breakeven?

A new loan with a longer term lowers the payment partly by repaying principal more slowly. The true breakeven adds the difference in remaining balances, so it only counts real savings.

Should I roll closing costs into the loan?

Rolling them in avoids paying cash now but increases the balance and the interest you pay. The calculator handles both options.

When is refinancing worth it?

Generally when you will keep the loan well past the breakeven point. If you may sell or refinance again before then, it can cost more than it saves.

Does this include taxes and insurance?

No. It compares principal and interest only, since property tax and insurance do not change with a refinance.
