I contribute 3% because that's all my company matches. Anyone putting more than the company match into their 401k is essentially throwing money away. The rest of your retirement savings should be going into an IRA. The fees for a 401k are higher and the choices are usually very limited. They fund choices can even be biased if the company is getting a discount to offer them.
