We have a 401k where I work. The company guarantees they'll match 50% up to a 6% investment by the employees. FRom the beginning in 1993 the company graciously matched our 6% contribution 100% . sounds like a great deal but it really isn't for numerous reasons. First, the total dollar I can contribute is limited due to poor participation in the plan. Second, Fidelity manages the fund and the fees are ridiculous. Also, Fidelity has terrible performance on really mediocre funds available in the plan. Frankly, if the company didn't match our funds 100% I wouldn't participate in the plan. It wouldn't pay!!!
