Wht is d best way 2 invest money...if d persons salary is 20k....?

1. Make sure you have 6 months of living expenses saved first.
2. Get rid of debt if you have it (credit cards, student loans, etc).
3. Participate in your company's 401(k) service.
4. Invest in your education so your income over time is more than 20k. The extra money will help in your savings and investing goals more than investing right now.

How much do you have in savings? Before starting your "investment" make sure you have 6 months of living expenses stored away. Next question would be, what are you investing for? If it is for retirement, does your company off 401k matching? If so, take advantage of that up to their matching %. Look into opening a ROTH IRA account.

1. Savings Account (www.ingdirect.com 4.5%) 6 months living expense

2. Company 401k matching

3. ROTH IRA until it's maxed out for the year

If you make 20K a year, it all depends on your lifestyle of living, how old you are and how much you can save up. If you can save up around $150 a month, that'll be $1800 that you can use to invest. At your income range (which is close to mine) I would invest in something along the lines of mutual funds or ETF's. I would allocate around 75% of the money into growth-and-income funds of any mutual fund for long term growth, where the other 25% you could put into different ETF's (which can make more money than mutual funds, but more risky). That way it gives you solid support for growth and extra for moving around if needed.
