How naive can the OP be? More math for ya…
http://www.thesimpledollar.com/2007/04/26/compound-interest-versus-inflation-the-battle-for-your-money/I put together a rough excel calculation showing the purchasing power of $500,000 after twenty years with 3% inflation if you chose to not invest at all:
Yr: Purchase power: Inflation taken:
0 $500,000.00 $15,000.00
1 $485,000.00 $14,550.00
2 $470,450.00 $14,113.50
3 $456,336.50 $13,690.10
4 $442,646.41 $13,279.39
5 $429,367.01 $12,881.01
6 $416,486.00 $12,494.58
7 $403,991.42 $12,119.74
8 $391,871.68 $11,756.15
9 $380,115.53 $11,403.47
10 $368,712.06 $11,061.36
11 $357,650.70 $10,729.52
12 $346,921.18 $10,407.64
13 $336,513.55 $10,095.41
14 $326,418.14 $9,792.54
15 $316,625.59 $9,498.77
16 $307,126.83 $9,213.80
17 $297,913.02 $8,937.39
18 $288,975.63 $8,669.27
19 $280,306.36 $8,409.19
20 $271,897.17 $8,156.92
$270,000 if you choose to retire will not afford you much after twenty years, and will require you to work until you die, assuming you’re even healthy at that point.
Say you live today with your budget for housing and living costs being 25k per year, with inflation averaging 3% per year, your cost of living also goes up.
Yr: Cost of living: Added cost of inflation:
0 $25,000.00 $750.00
1 $25,750.00 $772.50
2 $26,522.50 $795.68
3 $27,318.18 $819.55
4 $28,137.72 $844.13
...
18 $42,560.83 $1,276.82
19 $43,837.65 $1,315.13
20 $45,152.78 $1,354.58
So if you have $500,000 in todays dollars in 20 years (really $270,000 purchasing power) and do nothing and want to retire, you’ll be lucky to afford 6 years of non-working time because you’ll need to spend $45,000 to survive per year.
Same amount if you averaged 7% after investing:
Yr: Balance: Earnings:
0 $500,000.00 $35,000.00
1 $535,000.00 $37,450.00
2 $572,450.00 $40,071.50
3 $612,521.50 $42,876.51
4 $655,398.01 $45,877.86
5 $701,275.87 $49,089.31
6 $750,365.18 $52,525.56
7 $802,890.74 $56,202.35
8 $859,093.09 $60,136.52
9 $919,229.61 $64,346.07
10 $983,575.68 $68,850.30
11 $1,052,425.98 $73,669.82
12 $1,126,095.79 $78,826.71
13 $1,204,922.50 $84,344.58
14 $1,289,267.08 $90,248.70
15 $1,379,515.77 $96,566.10
16 $1,476,081.87 $103,325.73
17 $1,579,407.61 $110,558.53
18 $1,689,966.14 $118,297.63
19 $1,808,263.77 $126,578.46
20 $1,934,842.23 $135,438.96
So if you invested and things worked out good, you could have a safe withdraw rate of 4%, you’ll get $76,000 per year (beating inflation with some left over). Likely less if you pay taxes, but you can afford to not work for 40+ years in this scenario.
Let’s look at 1975 and having $500,000…
http://www.westegg.com/inflation/The thing is, is that the OP is the type of person that will be bitching how broke he is when he’s 70 years old, and voting to enact a tax on everyones Roth IRA so he can eat :dubious:

These charts are confusing to me, I know i am stupid, but can you explain why you should take the defltionary effect in purchasing power of today’s amount and also take into effect the projected inflation itself. IOW you say $500K today will be worth $270K in 20 years while at the same time a $25,000 lifestyle will cost $45,000 to maintain. Shouldn’t only one of these numbers be relevant?
