I did a little spreadsheet that examined the effect of income, expenses, and rates of return on time to $2 million overall, and # of years from 0 to $1 million vs. # of years from $1 million ro $2 million.
Assumptions: Tax rate rises slowly as income rises, maxxes out at 50%, starting at age 22 with $0 saved
Ignoring inflation, looking at real rate of return, income, and letting real spending (not including taxes) rise at 1% per year. Salary rising 5%/year (real).
Base expenses of $30,000, real rate of return 5%
Reaching $2 million at age...
Starting salary $50,000 - age 50 (21 years to $1 million, 7 to $2 million)
Starting salary $100,000 - age 41 (13,6)
Starting salary $200,000 - age 35 (8,5)
Base expenses of $30,000, real rate of return 7%
Reaching $2 million at age...
Starting salary $50,000 - age 47 (19,6)
Starting salary $100,000 - age 39 (12,7)
Starting salary $200,000 - age 34 (8,4)
Base expenses of $30,000, real rate of return 15%
Reaching $2 million at age...
Starting salary $50,000 - age 41 (15,4)
Starting salary $100,000 - age 35 (9,3)
Starting salary $200,000 - age 32 (7,3)
Base expenses of $60,000, real rate of return 5%
Reaching $2 million at age...
Starting salary $50,000 - age 92 (39,6)
Starting salary $100,000 - age 48 (19,7)
Starting salary $200,000 - age 38 (11,5)
So, some observations on this info...
- Time to double from $1 million is consistently much lower than time to $1 million. In other words, once you've gotten to $1 million, if you keep doing what you're doing you're pretty likely to double it quickly.
- The biggest influence on how fast you get to multimillionaire status is your earnings as opposed to your expenses or rate of return unless you manage to get a very high rate of return.
- In the example where base expenses are $60,000 and salary starts at $50,000, the debt burden grows for the first 16 years and net worth doesn't get back to 0 until age 48 - 26 years after starting to work - so this shows the effect of living beyond your means
- You can definitely cut down time to retirement if you manage to get a 15% ROR but good luck with that. My take is that you can get there fast enough as it is with a lot lower risk, so why risk getting wiped out?
- (My biggest takeaway from this) If you keep your expenses down, start with a living wage, and are able to have decent salary progress over the course of your career, FIREing as a multimillionaire is within the reach of just about anyone in a developed economy, provided that the financial markets yield something on lower than but near their historical average over the next 20-40 years.
