There might be a mistake with the $90k/yr leftover though. If you lose 35% of $250k/yr to tax (87.5k) and need to save $93k each year, then you should only have about $70k/yr left.
This is 5.8k a month to support two people which is barely doable for me personally (according to my past spending trends on mint.com).
It's not easy, but it's doable.
There are other ways to reach a million in 8 years, but this is a pretty sure-fire one.
- Explore other investment types and vehicles (e.g., optimize for cash flow, real estate, increased risk) to accelerate asset growth.
- Make more money somewhere else (including taking advantage of simple stuff like 401(k) matching).
- Assume you're going to make more money later (and save more money later) / get a better job.
- Hope for a huge exit / win the lottery / rich uncle inheritance.
The capital is there: the question is whether you can live the lifestyle you want in Silicon Valley on $90k/yr. (Assuming Uncle Sam takes ~35% in taxes and you incur no debt otherwise.)
