Help me with how much to contribute to parents, advice needed.

Hi, so I am 25F residing in Bangalore, I am getting 19.75 LPA CTC, where 8.75 Lakhs is just RSU. My inhand salary is 10 LPA, I recently shifted my job previously I was just earning 4 LPA in hand and I used to get 40k per month, out of which 11k I used to give to my parents, from which my dad invested around 5k, 14k rent and rest for my expenses. Now my inhand salary is 75k after PF deduction, how much should I contribute to my parents and how much should I invest on my own. Rent and other house expenses - 14k approx I am thinking of giving my parents around 17 to 18k as they live in a very small town or village, in Tamil Nadu. Now till June I will only have 55k with me as I have to pay back my aunt 95k, so I am thinking to give her 20k till I clear the debt. So during that time I am thinking to give my parents around 12k. I also have told them I can contribute to electricity and wifi charges. Can you please suggest me how much should I give them and how much should I invest? Thanks. I am sorta bad at finance, would really appreciate your help.
