refinancing. Build a spreadsheet model to evaluate this offer. The Excel function: = PMT (rate, nper, pv,fvs type) calculates the payment for a loan based on constant payments and a constant interest rate. The arguments of this function are: rate = the interest rate for the loan nper = the total number of payments pv= present value (the amount borrowed) fV= future value [the desired cash balance after the last payment (usually 0 )] type = payment type (0= end of period, 1= beginning of the period ) Also, for payment calculations, we assume that the payment is made at the end of the month. (1+r)t1K 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". refinancing. Build a spreadsheet model to evaluate this offer.
