Hello,

Can someone please help me with this MBS question.

A homeowner has a 30 year 5% fixed rate mortgage, with a current balance of USD 250,000. Mortgage rates have been decreasing. If the existing mortgage is refinanced into a new 30 year 4% fixed rate mortgae, how much will the homeowner save monthly.

I know the formula i.e. r (1+r)^n / (1+r) but I am not getting the answer. I do not have access to your forum, hence couldn't check if anyone else has asked this question.

Hi,
here find first find the monthly payment with old mortgage as: MP1 = (250,000*(5%/12))/(1-1/(1+5%/12)^360)= 1342.054
the monthly payment with new mortgage as: MP2 = (250,000*(4%/12))/(1-1/(1+4%/12)^360)=1193.5382
Thus the monthly savings = MP1-MP2 = 1342.054-1193.5382=$ 148.5158.
thanks
