That much is obvious. Beyond that things get fuzzy. How much will you need? How should it be allocated? What financial vehicles are best? The questions go on and on.
A little information is dangerous
It's easy to drown in the torrent of information and opinions. In fact, it's tempting to just give up and trust in fate. After all, retirement is years away!
But giving up is just about the worst thing you can do, because doing anything -- anything at all! -- to prepare for retirement will pay off. And no matter what the "best" plan is, a simple strategy that moves you toward retirement security beats any strategy that's too complex for you to follow.
Here's the simplest retirement plan I know:
Step 1: Write down your age.
Step 2: Every payday, put whatever you can into the Vanguard Target Retirement Fund that matches your age.
Step 3: When 4% of your account balance equals or exceeds your annual expenses, retire.
If you know how old you are, you've already completed Step 1. See how easy that is?
Sure, this plan ignores IRAs, 401(k)s, 403(b)s, TSPs, employer matches, asset allocation, tax effects, and the time value of money.
Those things matter if you're trying to build the perfect retirement plan. None of them matter, though, if they're so cumbersome you're considering doing nothing at all.
What you get for your money
When you make that one-stop shop the home for your retirement cash, you get a low-cost mutual fund that:
Here's how it works: The target funds invest in other low-cost Vanguard funds, shifting their allocations over time to model appropriate diversification. What start out as fairly aggressive, stock-heavy allocations while you're in your 20s gradually morph into conservative and bond-heavy allocations the closer you get to retirement.
If you buy a target fund, here's what you get in proportions appropriate to your age:

Is that all there is to it?
Making the commitment to invest for your retirement and following through with that commitment are the two most critical parts of any retirement plan. Once you've mastered those hurdles, you can move on to figuring out how to do it more efficiently. Done right, retirement planning can take years of time and thousands of dollars off the amount you need to invest to reach a successful retirement.
