no answer for this one.. depend on each individual..

how to define the "safe".. let say u want to have 6 months of savings only consider save.. estimate 30k = 6 months.. 1 month u earned 5k.. let say u spend 60% monthly.. 40% savings then 2k per month.. u need save at least 25 months only got 30k..

unless u going to say ur salary is 10k+ monthly.. but i believe monthly expenses always take about 60% of income..
