The Dow was at $270 in Jan 1952 and ended 1994 around $3770. The easy
calculation is $150,000 invested over that time and then subtract
taxes at the end:
$150,000/$270 = 555.55 "shares" of Dow in 1952
555.55 * $3,770 = $2,094,423 in 1994
$4,188,884.7 * 0.65 = $1,361,375 after taxes in 1994
$1,000 30 year bonds in 1952 had a redemption value of $7,125.60 in 1982.
$150,000 at that rate turns into $1,068,840 in 1982 where bond rates
were 6.66% so from 1982 to 1994 that turns into:
$1,068,840 @ 6.66% for 12 years = $2,378,045
$2,378,045 * 0.65 = $1,545,729 after taxes in 1994
$1,361,375 + $1,545,729 = $2,907,104 total after taxes in 1994.
Then in 1982 you could get 6.66% bonds. 6.66% for 12 years
This is the quick easy way of course and not exactly what you asked
for (since taxes were considered at the end rather than yearly as you
requested. It's not too hard to find a tax differed investment and so
this is typically what would happen. If I'm feeling bored and have
over an hour or 2 to burn later then I'll crunch some numbers for your
real answer :) |
