Post tax 7 lac a month. Double income no kids, but not sure what do with all the money.

Me and my wife are 30 years old software engineer with no kids. Draw 7 lac a month please some yearly bonus. We invest 2 lac a month combined into equity market through mutual funds.

Expenses: 1.5 lac a month including everything, lives in Bangalore in good society, owns a car, don't thing much before spending.

Still after everything left with 3 lakhs every month in bank account. Not sure how to use that. We both don't have any fancy "shauk" where we can spend and hence don't have an urge to earn more.

Any suggestions???
