Well to explain more as well as why I prefer investing to how SS is run… (Bet you didn’t think I’d go there again…) ;-)
The individual median salary in the USA is currently $44,225 annually and 13.3% goes to SS and Medicare. But let’s see what the projection would be if that 13.3% went into an S&P index fund instead. Also since the index fund is highly diversified, we don’t have to worry about market fluctuations so can just put the money in and forget about it until retirement.
Inflation is real, but we can ignore it for now since we don’t know what it will be in the future. We’ll pretend that it doesn’t exist. That way we can compare the retirement dollars with current value. Also we’ll pretend that you never get a pay raise and remain at the median salary.
OK - historically over time the S&P500 has had an annual growth rate close to 10% annually, but we’ll be more conservative and go with an 8% annual growth.
Currently about 13.3% of the salary goes to SS and medicare (for the median salary that’s $6766/year), but suppose it went into the fund. At an annual growth rate of 8%, after 30 years, the fund would have a value of $766,522 and after 40 years of only making the median income, you’d have $1,752,887 for retirement. (Yes - the magic of compounding!).
Using the 4% rule you’d be able to safely withdraw $30,666/year or $2,555/month if you quit work after 30 years. If you started work at 20, that would be retiring at 50. Since you only withdrew 4% and the historical growth is at 8% the fund would continue to grow even though you had withdrawn. Also the money would only be taxed as long term capital gains, not ordinary income.
But if you kept working until 60 that would be 40 years of working at the median salary, you’d be getting $70,115/year or $5842/month - still using the 4% rule. Yep, you’d be getting almost double what you were earning while working.
