How much savings should i have at age 21?

Assuming that you start from scratch and have used every opportunity available to earn money, e.g. part-time work during vacation, you should have around $20k to $30k in your savings.

Thereupon, the next thing is on how well you are using this money to maximise its value. =)

Here is everything about me and what I do best.

Assuming you are still studying, at least enough monies to cover your daily expenses until your school holidays
