Good deal? It's horrible? $0% after 20 years instead of the now, 50%. They're only matching up to 5%. That would average, for an enlisted guy:
Years 1-5: $1,250/Yr
Years 6-10: $1,750/Yr
Years 11-15: $2,250/Yr
Years 16-20: $2,750/Yr
That's only $40k over your 20 year career that they've contributed on your behalf...I need that to double 4 times over again to be better than the extra 10% retirement for the rest of my life.
40% @ 20Yrs: 24k
50% @ 20Yrs: 30k
That extra $6k/Yr comes out to a quarter mil provided I can live another 40 years after retirement.
Man, our retirement is so embarrassing when you lay it out on paper. $30k/Yr after serving for 20 years...
Berline,
To get the 5% match the individual would also commit 5% - which is now 10% of income. But that really is not 10% out of your net, it will be more like 3% or 4% eh... So, not so bad... Also, remember that many expenses are paid wholly or in part by the military (food, housing, medical) so even the initial salary is not so bad...
Most would recommend the individual commit 10% of salary to retirement (really about 7% net). That brings the contribution to 15%. But, let us use your numbers:
Starting Savings at 18: $0
Retirement Age: 65
Starting Age: 18
Withdrawl till: 85
Annual Yield: 8%
Inflation: 3%
Annual Contribution: $2,500 (ie, 10% of gross salary)
That leaves you with a nest egg $1,400,000 at age 65.
for an annual income of about $30,000/year from TSP
Plus you still get $24,000/year from your pension
And you get medical benefits among others.
Also, remember, your TSP is your money - not a promise by today's politicians to be honored by future politicians.
Also, the assets in TSP are transferable. So, let us say you 'retire' from the military at age 40. You will have about $180K that can be moved in your next IRA or 401(k) and you will be getting your pension of $24,000 from that point onward and you will still be getting medical benefits. Personally, I would strongly suspect that the projected individual would be in a position at age 50 where he/she could contribute more than $3,250 toward his/her retirement so the final TSP nest egg is most likely much larger than the above number. You will do great in this deal.
I would take this deal in a heart beat. Starting early is the key, and the projected system seems to get things moving.
