Index Match Match problem

Hi I wonder if and how I can use a Index Match formula instead of this which take quite som time to process:

E11: {=SUM(($B6=INPUT!$G$5:$G$988)*(F$3=MONTH(INPUT!$B$5:$B$988))*(INPUT!$F$5:$F$988))}

Month (1-12) in E3:P3

The formula is from my personal budget (see attached file) where I import banking transaction directly to my Input page.
I just add the account ID in INPUT!G5:G988 to place the transaction in the corresponding account in page 2013.

So how to sum transactions in INPUT!E column which match the same month and ID in the 2013 page.
In addition is it possible to include both the in -and out column in the formula so I don't have to change formula
based on income and expenses. (Sorry for any poor english).
