Checking the math on a Truth-in-Lending Disclosure
As your question is written now, it looks like you have a typo.  Your stated APR is 5.542% = 0.05542, not 0.005542 as you've written.  I ran the numbers that you gave (accounting for the typo) through the formula at Wikipedia and got $849.2528 / month, which will round to $849.25 for most payments.  That doesn't match the number that you computed or the number on your TIL. (Maybe you also miskeyed the result of your calculation?) I agree that it's unlikely that this is just a calculation error by the mortgage company, although I wouldn't completely rule it out.  Are you paying anything else like a property tax escrow?  I didn't pull a blank TIL form to see what might go into the monthly payment line that you showed, but in many cases you do pay more than just principle and interest each month. (Not sure if that gets reflected at that point on the form though.)
