Interest only payment
I have a spreadsheet that takes everyones current mortgage amounts and
calculates their new payments at my "advertised" rate. What I'd like to do is find a formula to determine how to figure an interest only payment based off of the standard =pmt(rate,nper,pv) formula. Assuming that the loan will be interest only for the first 5 years of the loan. Thanks for any advice! |
I dont know the specifics of what you'd like to offer but...You can use
simple interest (original(or current) amount *interest rate/12) for the interest payment for the first 5 years, and the PMT formula for the payment amounts after 5 years. EX: 300,000 mortgage 360 months 6% =300k*.06/12 = $1,500(initial pmt of interest only for first 60 months) then for remaining 300 months payment amount... =PMT(0.06/12,300,300k) = $1,932.90 this assumes total payoff in 360 months. There is no need to use the payment formula for the first 5 years as you only need the interest due. hth, Dave "origin8r" wrote: I have a spreadsheet that takes everyones current mortgage amounts and calculates their new payments at my "advertised" rate.

... how to figure an interest only payment based
off of the standard =pmt(rate,nper,pv) formula. Hi. In the Pmt formula, as the time period tends towards infinity, the basic monthly payment tends to only interest. Therefore, if you use a time period of say 10000 months, the payment formula will return the interest payment. =PMT(6%/12,10000,300000) Returns: $1,500 The $1,500 interest only calculation may also be calculated by finding the interest portion of the "first" payment. =IPMT(6%/12,1,360,300000) returns: $1,500 HTH :) -- Dana DeLouis Win XP & Office 2003 "origin8r" wrote in message ...
