Who are the Bogleheads - age adjusted net worth
Taylor's thread about Who Are the Bogleheads http://www.bogleheads.org/forum/viewtop ... 7#p1269919 stated one poll indicated 48% have net worth over $1 million. Another poll indicated the average age as 42. I'm interested in what the "age-adjusted net worth" would be. How about we use age 50 for these purposes.
So take your current NW and use a discount rate of 5% (not that the % matters that much, but let's all use the same % to get to comparable values) and figure out your NW at age 50. Unless you ARE 50, please don't answer with what your NW WAS at 50, rather what it WOULD have been at 50 using a 5% rate.
So if you are 30 years old, and have a current net worth of $300,000.00 your
NW(50) = $300,000 * (1.05) ^ 20 = $795,989.31.
If you are 60 years old, and have a current net worth of $2.0million, your
NW(50) = $2M / (1.05) ^ 10 = $1.228M

Re: Who are the Bogleheads - age adjusted net worth
I'm surprised nobody has shown up below $250K. When I got started as a Boglehead, I had a net worth of about $30K invested in Vanguard and TIAA-CREF, and I was 29; it took me several years of saving and investing, and the 1997-1999 bull market, to get to $250K assuming a 5% future growth rate.
Re: Who are the Bogleheads - age adjusted net worth
Income being ignored, anyone with a negative net worth really does not do well in this calculation no matter the circumstance.

Re: Who are the Bogleheads - age adjusted net worth
Of course this poll underrepresents the expected net worth of younger folks, as it ignores any new money those under 50 will be contributing.
It's also going to overrepresent any married person who reports the combined net worth of both spouses.

Re: Who are the Bogleheads - age adjusted net worth
That's true. No consideration for savings and earnings on savings. For a young Boglehead, this will severely underestimate the likely NW(50). In the case of young non-Boglehead, there's no consideration for excess spending, debt service, and poor investment performance. The approach likely overestimates NW(50) for that cohort!yobria wrote:Of course this poll underrepresents the expected net worth of younger folks, as it ignores any new money those under 50 will be contributing.
Also true, but I believe the census data also looks at family NW. So it's not unreasonable, but notable.It's also going to overrepresent any married person who reports the combined net worth of both spouses.

Oh well, I guess it's very difficult to design a poll to get a good picture of age-adjusted NW...

Not too surprising if you take into account selection bias (people on this forum are more successful than average) and reporting bias (among forum members the most successful are more likely to take the poll).Don Christy wrote:I'm fairly surprised to see ~32% with NW > $2M at 50...

Re: Who are the Bogleheads - age adjusted net worth
Although it's customary to include the value of illiquid assets in the calculation of your net worth, I tend to ignore these items (equity in home, autos, jewelery, etc...) since many of us (me included) have a bias to overestimate their value. To eliminate this bias, I simply focus on my goals established for liquid investment assets (stocks, bonds, cash, etc...) that are marked to market daily. It gets trickier if you own rental properties and interests in other businesses, so that's why I keep a typical balance sheet (including the value of illiquid assets) but really focus on building the value of income-producing assets.

I am nearly 49 so the age adjustment has no real effect. Including the value of my other possessions doesn't have much of an effect, either. I am in the just-over-$1M group.

This is a highly flawed method that is bias'ed toward older bogleheads. Income growth is not accounted for. For example, when I was 21 I made $35k per year. At 27, I was at ~$100k. Now at 32, I make $250k - $400k ($315k in 2011). The model you are presenting does not take this into account.

One other flaw, you are assuming compounded returns of 5%, how many on this board have been able to realize 5% compounded returns without a period of loss? Things do not rise in perpetuity. Also, are you including home equity as part of net worth. How many here believe they will realize 5% in compounded annual return on their home?

Maybe not achieved over the short term, but not a bad back of the envelop number to use. Make it 4% or 3% if you wish. If one is close to 50 it won't matter, and if far from 50 this all sort of falls apart on other grounds so the exact number does not matter all that much.

Re: Who are the Bogleheads - age adjusted net worth
My easyallocator app captured the combined investment accounts of a couple thousand Bogleheads/Diehards at one point. The average portfolio was $500K, and there was a fairly even distribution of ages between 20s and 70s.
So these numbers seem a bit high, unless people have a large amount of non-financial assets, on average.

Re: Who are the Bogleheads - age adjusted net worth
Perhaps we need a more significant calculator.
lol.
If over 50, enter net worth at 50/ divide by 2 if you are married.
If below 50, enter net worth at 50 , assuming realistic assumptions for wage growth plus savings. Perhaps income going up by 4 percent a year, account for your savings rate and 5-6 percent annualized return. Divide by 2 if you are married.
Exclude debt and equity on primary home. Add in net equity on vacations or rentals or otherwise invested homes.

Re: Who are the Bogleheads - age adjusted net worth
I agree, swaption. It should all count; that would equalize renters with more financial equity versus home owners who could sell their home and rent.
I don't think those married with nonworking spouses should divide by 2. It is simplest to report this as net household net worth. One's expenses do not double per person; the mortgage is the mortgage, etc. Those with two earning persons in the household/couplehood should report combined net worth.

There's something odd here. At age 68 my age-adjusted net worth is over $1M. But at age 50 I actually had only $220,000. That was one heck of a bull market.
That's including home values at both ages, but it's 90% investments. I included homes at both ages since they were paid for out of investments.

Re: Who are the Bogleheads - age adjusted net worth
This is a very interesting poll.
At age 26 with a NW of $57k, my age-adjusted NW was only about $186k. I wanted to add in a savings rate of $20k/year for comparison, so I created an excel sheet that has cell A1 = 57000. A2=A1*1.05+20000, A3=A2*1.05+20000, etc. After 24 years (age 50) the net worth comes out to be $1.004M! I think the savings rate makes a huge difference for a young person. Is there a way to factor this into the one-line formula?

You would also need to factor in income growth. So you may do $20k per year now, but when your income doubles you should be putting in $40k.bobblehead wrote:This is a very interesting poll.

I did think of increasing the 20k yearly, but I figured if the 5% is real return and we are talking about age 50 NW in today's dollars, my inflation-adjusted deposits might stay close 20k. I don't have any kids yet so who knows which way that savings rate will go!

Thanks, that explains it. At age 50 I started upping my savings rate because the mortgage was paid off that year. So if I backed out all that saving (it was not much compared to today's nominal result, not more than $30,000 per year till retirement)... that would leave me with a number, but it would be pretty meaningless.
