re: Yes, another retirement thread - RE: How much you need to retire

an old rule of thumb was that every $200,000 in savings would generate $10,000 in income for 25-30 years in retirement. So you'll need $1,000,000 saved for $50,000 in income needed in retirement. I also understand that prices double approx. every 20 years so $50,000 will only buy $25,000 of stuff 20 years from now due to inflation.

As for how much to save...A LOT.
10%/yr for necessities
15%/yr to be comfortable
20%/yr for a luxury lifestyle

ETA: inflation info
