My job only allows us to contribute 6% in to are 401k and they mach it by 3% is that good.?

I suspect (strongly), that your job lets you contribute 15 - 30% of your salary. Up to a max of $16,500. But only 3% of the first 6% is matched. Is that good(?) - it's not bad, but I don't know as I would characterize it as good. Some are better & some are worse.
