I would seek independent professional advice.\n\nWith a sum that size they would pay for themselves even if only in terms of money saved on taxes etc, and they will be able to advise on a range of investment opportunities and the risks and benefits of each.

Put $100,000 into a bank.\nPay off all my debt.\nBuy things I need (like new car or a new home)\nBuy some real estate.\nInvest the rest into Traditional IRA (you don't qualify for Roth IRA), mutual funds, stocks and bonds, education plans (if you have kids), and variable annuities.

It will take about $100,000 dollars and up to start. Why not start something cheaper? Start a business on something you know how to dobest.

I would invest in a concession business and I could do it for less than $100,000 including all my equipment so you could keep the other $4.9 million.\n\nI would do it for the freedom it would give me. I love to cook and be around people. My business plan currently under construction would enable me to fulfill my goals of making more money, working less time, and having more fun.

It naturally depends on what your starting capital is - and what your investment horizon is. Thus if you already have $1mn in the bank, and you leave it in a check account which yields 1% p.a., then after one year the bank will add $10,000 to your account :)

See a financial advisor.\n\nIt would be rare to double your money in a year.\n\nMost people would recommend a diverse portfolio.

Put in the percentage that maxes out the company match.  Free money is good.\n\nAfter that, put your money into a Roth IRA (if you qualify for it).  Tax-free growth is good.\n\nIf you max out the Roth IRA, go back to your 401(k) and put money into that.  Tax-deferred growth is good, but not as good as free money and tax-free growth.\n\nWhile you're doing all that, you have to also build an emergency fund of 3-6 months *expenses.*  You don't want an unexpected emergency to undo all that you're striving for.  Also, you need to make sure that you pay off all your short-term high-interest debt.  It makes no sense to gain 10% a year in savings while paying out 18% in interest.  If you have credit card debt, pay it off and stay out of debt.\n\nGood luck!
