|  |     I presume (which gets me into trouble form time to time) that you are
    looking for the standard Annuity formula; that is, for P=principal,
    n=number of periods, PMT = payment per period, and i = interest rate
    per period:
    
    PMT=P/((1-((1+i)^n))/i)

|  | For a fixed rate mortage,  the interest paid for a given month 
is just the balance x annual interest / 12.
You can verify this requesting this information from your
bank. Some banks print this information on the monthly statement.

| 459.3 | It's already out there | KALI::PLOUFF | Lifestyles of the unrich and anonymous | Mon Apr 26 1993 09:11 | 13 | 
|  |     There are several public domain programs for the IBM PC, UNIX systems,
    and various personal computers which do exactly what the basenoter
    desires.  A little poking around might save considerable time if the
    results are more important than the method.
    
    It's been my experience, though, that calculations done at home never
    match the bank's numbers exactly because of partial month payment at
    the beginning of the loan term, and because the bank probably uses a
    different calculation method than the simple formula for whatever
    (historic?) reason.  However, for results within $10-50 the PD software
    does just fine.

| 459.4 | Thanks! | MRSVAX::TSMITH | That rabbit's dynamite... | Mon Apr 26 1993 10:13 | 5 | 
|  | Thanks to everyone.  That's what I needed to know.  I guess I'll ask the bank
for an amortized schedule so I can see how close mine comes to it.
Cheers,

    ABSTRACTS.LIS in the same location lists ALL the tools available in the
    toolshed and a synopsis of each tool.
