It's called compound interest... $1100 per year drawing 5% over 30 years results in a total of $81,523. You'd a 14% rate of return *consistently* over 30 years to be able to support a $580,000 payout, and I just don't think that's realistic. Maybe for one or two years, but the last five years have been nowhere near that.
Rates of return for public employee pensions have been averaging between 7.5% and 8%, and those staying at 8% are getting a lot of flack for it.
And your $33,000 in seed money at $1100 per year would only net $149,500 over 30 years...
That's why I say the number is mathematically impossible. Maybe for one year out of the 30 that was the company's contribution, but I highly suspect it's averaging out to a lot more than that, especially with lifespans increasing and rates of return being lower over the past couple years.
When we were given the option of converting to the 401K in either 1999 or 2000, I was told that the company's pension contribution worked out to between 9% and 11%, which is why they were going with only the 401K for non-union new hires. Plugging in an 11% contribution with 7% rate of return comes back with a whole lot more realistic end result ($4800 per year grows to just shy of $530,000).
So, you can choose to take your total value statement as the end-all financial document, or you can go look for an online compound interest calculator and run a few scenarios on your own.
Your numbers are based on an individual account, not a defined benifit pension plan.
You are forgetting about the fact that I may not live to see a penny of any of that, unlike a 401K which goes into a fund and it passed on to heirs. If my wife and I die before we retire they keep all that money. Some years the company may put in 9% but in others, like 2009 they put in ZERO. There were years in the go-go 90s where they put in nothing, and even took excess earnings out of the plan and used it to prop up profits, with a disproportionate amount going to the executives through profit sharing and bonuses.
