Here's a link to a guide for someone who wants to retire at 65 with 80 percent of their working income:
The analysis includes social security etc
here's a link to the article:
If you want to retire at 50 then add 15 years to your age.
One thing to note is that the author assumes a 5 percent safe withdrawal rate. Which is probably too high for someone retireing at 50. The analysis shows that if you have saved 12 times your current income then at a 5 percent withdrawal rate your stash will provide 60 percent of your working income. Social Security is then assumed to get you up to the target 80 percent of income.
The analysis assumes that you earn an inflation adjusted rate of 5 percent on your money and that your salary keeps up with inflation.
This analysis may not be correct for many people. If your house is paid for your expenses may be much less than 80 percent of your current income. I find that my current expenses are only about 30 percent of my income. So for me, I could get by on much less than 80 percent of my income. So, the 60 percent of income that the 12 times current income savings provides would be more than enough for me.
If you find that with your expenses that you can get by on say two thirds of the suggested 60 percent of your income then just scale all of the numbers back by the factor 0.66 (40/60 = 0.66)
Nonetheless, the table is a somewhat useful guide for how much savings you should have.
So to answer your question directly
- As a 34 year old (rounded to 35) that wants to retire at 50-55 you should have savings right now of between 3 and 4.5 times your current salary. That would be $270k to $405k for your $90k income. Your debt including house mortgage should be below 0.75-1.0 times your current salary. So your total debt should be below $67.5 to $90k for your $90k income level.
It wasn't clear how your savings and net worth were distributed. So if your net worth (savings) is $140k exclusive of home equity then you will need to work an addition 5-10 years (to 55-60 years old) before you can retire. If your net worth is $340k exclusive of home equity then you are on track for your 50-55 year old ER date.
