Well your employer has to offer a 401 if yo want to go that way...nice and easy money, comes out of your check before you even "see" it.
But if no 401 then it's time you got some IRA's under your belt...if you got some savings you can put $ 4000. into an IRA..( Traditional ...if you end up "paying" at tax time....ROTH, if you don't get hurt too much at tax time)
So.. you know how to use a computer, you can go to an outfit like Fidelity, or E-trade...and open an account on-line....then do just a little reading about " mutual funds" at yahoo/finance or Kiplinger's website......... first- time around get into something called balanced....may have some " safety" aspects to it...
All this reading and prep stuff only takes a few days out of your life...take the time...you won't regret it in 20 years.
Anything you don't understand or have trouble with, ASK again..there are a few good people answering here ..you'll do fine.
P.S. You can certainly start with less than the $ 4000. ...but I think that's the most you can add for a few years.

That's a very important question. {This answer is just a start to your question. You should learn more about investing to really get a thorough understanding of your retirement options.}

ANSWER: You should probably start by looking at your company 401k retirement plan. The plan is tax-deferred (you don't pay taxes on your investment gains until you pull the money out during retirement) and they may offer a "match" (for example, you put in 3% of your income and your employer "matches" with an ADDITIONAL 3%).

Your 401k will offer various mutual funds to invest in. See if your employer offers advice through an advisor to help you decide which funds to go into. They also may be able to create a simple investment plan for you.

Hope that helps out! And remember: try to save 10% of your income even if you start out with only 2-3% in the beginning.

Honestly, ... try this.

I am an investor with them and have a US$50K portfolio there. I'm getting paid every month on time as promised and guaranteed. The average returns are 20% per MONTH!
You can recover your initial investment amount within 8 months and then it's profits on the run from there.
Read the details...it's easy to understand.
It's not an MLM...nothing to 'market'. You can just be an investor and reap ur returns which are guaranteed as stipulated.
You can visit my financial site provided by them at www.swisscash.net/sgamk1632202
There are alot of negative blogs and people tagging it as a scam.
I know what has happened. There were reports that SC investors scammed others...but I wonder why the corrected newspaper reports are not being circulated. It was never a SC involvement but some clowns scamming others by encouraging them to invest with some Swiss Union Bank. Anyway, hell with others. SO far there has been no complaint from a single SC investor that he/she did not get paid as guaranteed.
By the way, I am in touch with some senior consultants of Swisscash and I must say, they are serious dynamic professionals and I'm confident they will be profitable for at least the next few years.
I started with $1K initially and then after my confidence with them, I have now increased to $50,000.
