Not quite the same. Amortization of debt is a little different from an annuity. You're decreasing the debt by your payment, minus the interest the bank charges you. As the principal gets smaller, a larger amount of your payment goes to paying the principal. I think you pointed me in the right direction, though. I found a set of formulas in Wikipedia under "Time value of money". I think this is the one I want: <http://en.wikipedia.org/wiki/Time_value_of_money#Example_5:_Calculate_the_v alue_of_a_regular_savings_deposit_in_the_future.> I'll convert that to ActionScript and post it for the archives.
