Can saving/investing 15% of your income starting age 25, likely make you a millionaire?
As others have shown, if you assume that you can get 6% and you invest 15% of a reasonable US salary then you can hit 1 million by the time you retire. If you invest in property in a market like the UK (where I come from...) then insane house price inflation will do it for you as well. In 1968 my parents bought a house for £8000. They had a mortgage on it for about 75% of the value. They don't live there but that house is now valued at about £750,000. Okay, that's close to 60 years, but with a 55 year working life that's not so unreasonable. If you assume the property market (or the shares market) can go on rising forever... then invest in as much property as you can with your 15% as mortgage payments... and watch the million roll in. Of course, you've also got rent on your property portfolio as well in the intervening years. However, take the long view. Inflation will hit what a million is worth. In 1968, a million was a ridiculously huge amount of money. Now it's 'Pah, so what, real rich people have billions'. You'll get your million and it will not be enough to retire comfortably on! In 1968 my parents salaries as skilled people were about £2000 a year... equivalent jobs now pay closer to £50,000... 25x salary inflation in the time. Do that again, skilled professional salary in 60 years of £125000 a year... so your million is actually 4 years salary.  Not being relentlessly negative... just suggesting that a financial target like 'own a million (dollars)' isn't a good strategy. 'Own something that yields a decent amount of money' is a better one.
