The following explanation is the basic idea of refinancing a mortgage/home. In other words, when refinancing the mortgage, you stop the current mortgage, get a new mortgage, pay off the remaining balance of the current mortgage using the new loan amount, and then start paying off the new mortgage according to the terms of the new mortgage.

Suppose that you are currently making monthly payments on a $178,920 30-year mortgage at 5.56% interest compounded monthly. For the last 6 years, you have been paying the regular monthly payments. You now have the option to refinance your current mortgage with a new 30year mortgage that has an interest rate of 5.08% compounded monthly. Note that the lender of the new loan has a closing cost fee of $1,650 (for title insurance, home appraisal costs, etc.) for the new (refinanced) mortgage. The lender stipulates that closing cost must be paid in cash and cannot be part of the new loan. You are to determine whether you would save or lose money in interest if you were to refinance your home. Take the closing costs into account when determining if you would save or lose money.
