I save a specific amount of money for emergencies, then proceed to save to invest. I set aside maybe ten to twenty percent of what I earn each month. The rest are used for basic living expenses, rent, debt, etc.
I cannot say how much money I set aside every month because my earnings fluctuates. I don't even have "I will set aside x percent of money every month" kind of financial planning. Since my earning is not fixed, I don't have fixed amount or percentage to set aside. However, I make sure every month I save money. On the month when my earnings are high, I will have more money on my saving account and when I earn less, I will have sell money on my saving account.
