Recently married peeps - How or in what ratio do you divide non-monthly expenses/savings like home EMI/downpayment for future, saving for foreign/domestic trips, starting a family etc?

I earn 1.5 lakhs/month while my wife gets 86k/month (both carry-home). I know every case is unique but just want to know any general rule of thumb that young couples follow. For our monthly expenses (rent and groceries), I pay 2/3rd and my wife contributes 1/3rd of the total. We live in Gurgaon.
