in reply to Calculate Mortgage Payment

The Mortgage Calculator dies with internal server error if you leave the "Years" field empty. You might want to do some error processing there.

Alternatively, the way I think about paying mortgages I say I want to pay a monthly amount X, for how many years and months will I have to pay it off?
You could offer that as an alternative, too.

Cheers, Sören

    And, just for enjoy, another quests are
    - calculate remaining payments when some payments are fixed (in time and in value, too)
    - calculate interest rate when all but non-equal payments are known, specially, when price is split into more than one payment... a little bit tricky, more than one interest rate can be the solution :)
