A few years back, Dave and Jana bought a new home. They borrowed $230,415 at an annual fixed rate of 5.49% (15-year term) with monthly payments of $1,881.46. They just made their 25th payment, and the current balance on the loan is $208,555.87. Interest rates are at an all-time low, and Dave and Jana are thinking of refinancing to a new 15-year fixed loan. Their bank has made the following offer: 15-year term, 3.0%, plus out-of-pocket costs of $2,937. The out-of-pocket costs must be paid in full at the time of refinancing. Build a spreadsheet model to evaluate this offer. The Excel function: =PMT(rate, nper, pv, fv, type) calculates the payment for a loan based on constant payments and a constant interest rate. The arguments of this function are:
For example, for Dave and Jana’s original loan, there will be 180 payments (12*15 = 180), so we would use =PMT(0.0549/12, 180, 230415,0,0) = $1,881.46. Note that because payments are made monthly, the annual interest rate must be expressed as a monthly rate. Also, for payment calculations, we assume that the payment is made at the end of the month. The savings from refinancing occur over time, and therefore need to be discounted back to current dollars. The formula for converting K dollars saved t months from now to current dollars is: where r is the monthly inflation rate. Assume that r = 0.002 and that Dave and Jana make their payment at the end of each month. Use your model to calculate the savings in current dollars associated with the refinanced loan versus staying with the original loan. If required, round your answer to the nearest whole dollar amount. If your answer is negative use “minus sign”. |
As per the new term loan, the monthly Payment would be $1440.25
That would mean a saving of $441.21 per month for the remaining 155 months (180-25). However we have to keep in mind the extra 1440.25 that we have to pay for extra 25 months as the new term is of 15 years.
So the NPV comes out to be 33010.85
But we have to pay upfront cost of 2937. That would still be better than the current Loan Structure
as 33010.85-2937 is still positive Savings
