75% of the first 8% of pay (so I contribute 8%, they contribute 6%) with 100% immediate vesting for both contributions. I also joined the last year that they offered pension benefits. Kind of hard to say what % the benefits are, depends on how long you work for the company, what age you start collecting, if you have spousal survival, etc. As it is though, I've been working there for 5 years and would get $500 for the rest of my life if I start collecting at age 65 (I'm 35). If I stay here for 10 more years, that will increase (estimated) to $1700 per month. I figure I have about 8 more years till FI, not sure if I will spend all of them at current employer though.
