Thanks. I get 1st quarter Sum using this formula. Now my question is -
1. how to get sum for 2nd 3rd and 4th Quarter?

=SUMPRODUCT(--(INT((MONTH($A$2:$A$13)+2)/3)=2),$B$2:$B$13)

or better, put the quarter number in a cell, say H1, and use

=SUMPRODUCT(--(INT((MONTH($A$2:$A$13)+2)/3)=H1),$B$2:$B$13)

etc.

2. how to get sum for each month?

put the month number in a acell and use

=SUMPRODUCT((--($A$2:$A$13<>""),--(MONTH($A$2:$A$13)=H1),$B$2:$B$13)

etc.

The answer for Question No. 1. is working perfect!
But your formula returns error message for my Question 2. The pop up with
mesage that "the formula you have entered has an error"

One bracket too many

=SUMPRODUCT(--($A$2:$A$13<>""),--(MONTH($A$2:$A$13)=H1),$B$2:$B$13)
