    I don't think there is a simple way to figure out payments on a handheld calculator unless it has that specific function. Here's a link to an amortization chart
    you can print out and take with you. If you search around the net you might find a better one. Hope this helps.

    I think I would just buy a mortgage calculator and then use that in the field. They are not that expensive, certainly much less than a PDA. Unless of course you already have a PDA, then I'd go that route.

    it is hard to do on a cheapo wal-mart calcutlator yes. but if you just by a calculator with a y^x function ( to the power of as you put it) thats all you need. Cost about $15

    Do you have excell or works on your computer?

    They both have a payment function on them.

    The formula looks like this


    Again on a calculator

    Payment = Principle * (1 - ( 1 / (1 + i )^n)) / i

    Where " i " = the monthly interest rate
    and " n " = the number of months for the loan

    You can do this on you computers calculator program also.

    1000= principle
    .05= rate, interest
    6/12 =time , in this case 1/2 year

    I got a free copy of "Financial Eight Rate Mortgage Tables" at my local bank. The books breaks down the percentage rates and princible into monthly payments nessecary to amortize a loan. Beats trying to figure it out on a calculator, faster to. The book I have goes from 7% to 18%, I am sure there are other books that cover more % rates.
