I'd say that this topic brings up a valid point. mr. & mrs made 3-4 times the median household income over 9.5 years, and accumulated $800,000 between savings and investment gains during that period (over $233,000 of it from investment gains). It follows that it will likely take you 3-4 times as long to accumulate the same amount if you are only making the national average.
Mr. & Mrs. MMM are no doubt very remarkable and hard-working in that they saved this much and retired by Age 30(by working, not by winning the lottery or creating some business or product that took off)
I've done the math and come up with them spending over $66,000 a year during the nine and half years they worked. There was a new car and a new motorcycle, vacations to mexico, hawaii, new zealand, australia, etc..
Here is the math:
Year: Salary + investment gains
0 - 1: 90,300 (assuming $41,000 x 1.5 years + 57,600 x .5 years =$61,500 + $28,800 )
2: 57,600
3: 77,000 + 7,000 ($3000 of stocks bought in year 2 sold for $10,000 in year 3)
4: 127,000 + 10,000 (employer matching $5,000 for each of them) (+ unknown investment gains)
5: 160,000 (+ employers probably still matching $5,000 for both + unknown investment gains)
6: 170,000 + 20,000 (+ employers probably still matching $5,000 each in both retirement accounts)
7: 170,000 + 30,000 (+ employers probably still matching $5,000 each in both )
8: 154,000 + 40,000 (+ employers probably still matching $5,000 each in both )
9: 110,000 + 135,000 (+ possible employer matching $5,000 in Mrs. MMM's retirement account)
10: 80,000 after spending
Salaries + Investment gains
$1,195,900 + $233,000 (not counting unknowns)
= $1,428,900 is how much they made in those 9.5 years not counting unknown investment gains and not counting $10,000 in 401k-matching in both of their jobs years 5 through 8 & Mrs. MMM in year 9
- $800,000 which is how much they had left of it
= $628,900 is how much they spent (again not counting unknown investment gains and employer-matching that they most likely had during years 5 through 9)
divided by 9.5 years
= $66,200/year was their average spending (plus the previously mentioned unknown income)
and $800,000 divided by 9.5 years = $84,210/year was their average savings + gains from investments + employer matching of their 401Ks
I also did not assume yearly raises when they weren't mentioned. I did make some conservative estimates when exact figures weren't given. For example, Mr. MMM stated that his salary with bonuses was $100,000 in year 5, while Mrs. MMM made $60,000, for a total of $160,000, so in year 6 and 7 when he said salary went up "slightly" and Mrs. MMM salary increased by $5,000, I conservatively estimated that they made $170,000. Also he said that he got a raise "some time" during year 1, so I assumed halfway through
Additional analysis:
***$1,428,900 of income divided by 9.5 years comes out to an average income of $150,410 a year, so they did in fact average over $150,000 a year during their working careers.
**** They spent about $66,000 a year, while accumulating about $84,000 a year from savings+investing+pensions
----------- $66,000 is 44% of $150,000 spending, while $84,000 is 56% savings/gains
*** $800,000 - $233,000 investment gains (not counting unknown) = $567,000 of direct savings
---------- that comes out to $59,684 per year of direct savings, while $24,526 came from from investment gains
------------ that comes out to 29.125% of the $800,000 net worth came from investment gains
***567,000 in savings comes out to 47% of the $1,195,900 they had earned in salaries. So, $567,000 or 47% is how much money they actually put away from their earnings, the rest was from favorable returns on investments and employer pensions
