If you have the opportunity to invest into your 401k with your career, do so. Max it out. Most employers will match whatever you contribute usually from 3-6%.

Body:

If you don't have a ROTH IRA set up, you should. This will compound over the years to when you reach retirement age, you will have millions in retirement. My job currently is international sales with elderly folk, and 50% of them are living off social security alone. They have miserable lives as a result.

Roth IRA you cap out at $130,000 a year. You won't have to worry about that unless you're one of America's top 10%.

You can invest $5,500 a year into your Roth IRA (I'd recommend going through Merilledge). This is essentially investing into stocks or mutual funds each month. Each trade (or share) that you buy is $7 service fee. You should be investing $105 a week into this. If you start with that by age 25, by the time you hit retirement age at 65, you will have over a million dollars in savings due to compound interest, dividends, and then your original investment. Gentlemen, this is the way to do it to provide for yourself.

The way I have it set up is I have an autotransfer of $105 straight into my investment account the day I get paid. So on my pay day every friday, I don't even see that additional money as it goes into investing.

The second thing I would say is be saving $500 a month, every month, for general life savings. You will want this for emergencies, for downpayments on condo or house, buying a new car, etc. This can be easily set up with an autotransfer as well out of your account into an additional savings account of $125 a week. I recommend doing this on your pay day.

You have an extra $230 a week to do this. If you don't, why not pick up an extra shift at your job? If you make shit money, I would highly recommend getting a job in sales. You can make some serious fuckin' money doing sales.

To recap:

$105 a week to investing in stocks. Make an appointment with a financial advisor through your bank. ($5,500 a year)

$125 a week to general savings / emergency funding. ($6,000 a year)

Easy peezy and you reap the benefits.
