It will drop the number of payments from 36 to 34.
First what is the loan amount now?
N=36
I= 6.6%/12 = 0.55%
PV= ????
FV= 0
Answer current balance is $20,427.09
What is we pay down by $1,100?
That drops the current balance to $19,327.09
Recalculate to see how many payments it would take to payoff $19,327.09
N= ????
I=6.6%/12 = .55%
PV= -$19,327.09
PMT = $627 PV and PMT must be opposite signs!
FV = 0 Paid off
Calculate
N= 34 a reduction of two payments. The $1,100 will save you 2X $627= $1,254 or net $154 over the life of the loan.
