There’s a lot of great suggestions here, but I just want to add a different possibility as well. Most investments mentioned here are very safe, but carry small returns, they are essentially savings accounts which can be good or bad.
If you’re tucking some rainy day money away for if your transmission blows up, you have to come up with a deposit on a new place you rent, or things like that those are great because you can get at the money fairly quickly and it doesn’t matter when.
If this is retirement money you’re trying to save, and I don’t vastly underestimate your age, you could probably mix in some of the other options you mention (mutual funds, index funds, stocks) and get a better return averaged out over the next 30+ years before retirement. Just as an example: a great interest bearing investment might get 5% or so, widespread stocks traditionally get something like 12% annually over the long haul, how you mix things up really just depends on your level of comfort with the risks involved.
I only mention that because pretty much any type of investment account will have a petrifying number of choices as to what you can put your money in. It freaks most people out more than any other part, what if they make a mistake? Are they going to lose their money? Can they trust the guy/gal who’s trying to push them one way or another? The important thing is just to get it started, the large majority of investments presented will make money.
I used to try and help people with their retirement accounts (401k’s in my case) by phone for one of the major investment companies. When people were first getting started I’d try to get a feel for 3 things.
1) How long is it really going to be before you need this money? There’s a lot of good reasons to get at your retirement money before retirement and some are protected against extra taxes depending on the type of account and the reason. For example, a lot of folks will take some out to put a down payment on a house or go back to school. Be honest and figure out how long you want to leave it alone.
2) How comfortable with risk are you? Without getting too into a personality test, most people know if risk freaks them out or not. Are you analytical about money or emotional? Are you going to check on your account every week online, or glance at statements with the thought that the money doesn’t exist to you for another 20 years?
3) What else do you have going on investment-wise? You (nikki) kind of already answered this but it’s something I would generally try to establish. If someone was putting all their extra cash into their small business they’re trying to grow they already have some high risk/high return cash out there. Maybe take a safe route with this just in case. The opposite is true if you already have some cash tucked away in savings.
This is getting way too long, so I’ll wrap it up by saying the longer you have, and the higher tolerance for risk you have, the more you should mix higher risk (read stock based) investments in. It just makes mathematical sense
Really though, you’re a smart young lady, read one book and you’ll use the information for the rest of your life and feel much more informed when interacting with whatever company you use.
And you won’t have to listen to long-winded flunky ex-401k reps for information :P
