When you sign up for retirement in the Florida state system, they actually give you an option of whether you want to select the defined benefit or defined contribution option, complete with nice charts & graphs of different retirement benefits you can select under different scenarios. Employer contribution into either option is the same dollar amount. If you're planning to be in the system for the long haul, even the optimistic projections for the defined contribution option put you at something like 30% less of a monthly pension amount than if you opt for the FRS defined benefit option.
Under the current rules, defined contribution only really makes sense if you're planning on being a short-timer, since it's only one year to vest for the defined contribution option compared to six to vest for defined benefit.
First, I would LOVE to see those graphs. 😀
Second, if we can get everyone into a system where their annual pay reflects what they really make, it would be much simpler to adjust for discrepancies. Based on my own back of the envelope math, I have no doubt the DCP provides less income. (The DBP represents a very cushy benefit for full timers.) But what the DCP does do is make it possible for us to understand what people actually make. Once we get there, THEN we can figure out if we need to adjust salaries to insure we pay people a compelling wage. You can't do that with a plan like the DBP.
