When it comes to guaranteed returns, there is a list of investments perhaps as numerous as your fingers. The most famous example is the 401(k) with an employer match. In order to charm you into investing some of your money in the company’s 401(k) account, most employers tend to put up a bit of their own money as an incentive. The return is immediate, guaranteed, and something that should be captured. The bottom line is – in almost all instances you should make sacrifices elsewhere in order to receive the full employer match.
