There are many ways you manage your money when you earn or make money. But the number one rule is you should not spend all of it. There are many ways you can divide up your money and many rules.

My favourite is 10/10/10/70 – Save 10%, Invest 10%, Donate 10% the remaining 70% should cover all your expenses. (from Richard Kiyosaki)

Another good one I recently came across is:

He said 75/15/10 – 75% Maximum you spend, 15% is the minimum you should invest, 10% is the minimum is what you save.
