"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years.

yes Mr ZVITAM is correct use formulas and create function

create function like this
<?php

function interest(\$invest,\$year,\$rate=15,\$n=1){
\$accumulated=0;
if (\$year > 1){
\$accumulated=interest(\$invest,\$year-1,\$rate,\$n);
}
\$accumulated += \$invest;
\$accumulated = \$accumulated * pow(1 + \$rate/(100 * \$n),\$n);
return \$accumulated;
}

?>

Thank you for your reply. I did try to do this in Sheets;but, in this situation I'd need to use "GoalSeek" which is not available.

Sub Calculate()

Sheets("Amort").Range("N22").Offset(rowOffset:=Sheets("Amort").Range("J5").Value, columnOffset:=0).GoalSeek Goal:=0, ChangingCell:=Sheets("Amort").Range("P10")
Sheets("Amort").Range("W22").Offset(rowOffset:=Sheets("Amort").Range("J5").Value, columnOffset:=0).GoalSeek Goal:=0, ChangingCell:=Sheets("Amort").Range("P12")
Sheets("Amort").Range("AY22").Offset(rowOffset:=Sheets("Amort").Range("J5").Value, columnOffset:=0).GoalSeek Goal:=0, ChangingCell:=Sheets("Amort").Range("P14")

End Sub

W22, N22, AY22 are the Loan amount 25,000.
J5 is 240 (20 Years)

My other alternative is to scrape the data from web, see picture attached
