The principal outstanding at the beginning of the loan period is the amount borrowed.
Amount borrowed is calculated using PV function in Excel :
rate = 7.75% / 12 (converting annual rate into monthly rate)
nper = 30 * 12 (30 year loan with 12 monthly payments each year)
pmt = -688.96 (monthly payment. This is entered as a negative number because it is a cash outflow)
PV is calculated to be $96,618.09
The total principal paid off after 13 years (156 months) is calculated using CUMPRINC function in Excel :
rate = 7.75% / 12 (converting annual rate into monthly rate)
nper = 30 * 12 (30 year loan with 12 monthly payments each year)
pv = 96168.09 (amount borrowed)
start period = 1 (we are calculating principal paid off between 1st and 156th month)
end period = 156 (we are calculating principal paid off between 1st and 156th month)
type = 0 (each payment is made at end of month)
CUMPRINC is calculated to be $18,180.40
Balance principal outstanding = $96,618.09 - $18,180.40 = $77,987.69
The loan payoff is $77,987.69
