How to calculate advance tax fy 2018-19

Hi,

I am trying to work out my advance tax payment FY18-19 (due on 15 Sep 18). With LTCG on equity wef 1/4/18, it is bit confusing hence seeking advice from experts. My income summary so far is as below:

Salary - Nil (retired)

Interest - 25000/-

STCG debt funds - 25000/-

LTCG debt funds - 1,25,000/-

LTCG equity shares - 3,75,000/-

Deductions : 40,000/-

Total income is 5,50,000/- and after deductions 5,10,000/-. I understand there is basic exempt slab of 2,50,000/- and that LTCG on equity is expempt for 1,00,000/-. LTCG on debt funds is charged flat at 20%. How should I compute my income tax due?
