Not taking a matching contribution for your 401k
If the words "401k" and "matching contribution" are foreign to you, let us Rosetta Stone that for you. Many employers offer the ability for their employees to sock away money in a retirement account (called a 401k), and to incentivize them to do so, they offer to match those contributions dollar for dollar up to a certain amount. And yet, people often don't do it. "It's free money!" Roberge says. C'mon, don't say no to free money.
Not putting away any money for retirement
And since Roberge recognizes some employers don't have a 401k option, you can still contribute to an IRA, or Individual Retirement Account. It's best to start contributing to it early, even if it's only a little, to take advantage of the fact that your money has time to grow, and when it does, that larger sum of money can grow. Roberge explains, "If you invest early and often when you're young, it's going to be much easier to satisfy the amount of money you need in your retirement account" when you hit 65 or so. Do your 65-year-old self a favor and start an IRA.
