Escrow: why don't I understand it?

[Nellie Bentz]

Anyone in here care to educate me a little on escrow? My escrow account keeps coming up with what seems like fairly large shortages.I'm not very good with math, and I've tried going over the escrow statement with my mortgage company, and I've walked away even more confused.  To make matters worse, I just refinanced recently and that seems to have caused an even larger shortage than the last time.

If someone could even just point me in the direction of a good resource for trying to understand how escrow works, maybe that will help me figure out if the mortgage company is mishandling my money some how....

Thanks in advance!
