I’ve been feeling an itch to learn new things in a more formal setting. There’s a lot of options from self learning, graduate school, and, recently, boot camps. I’ve been seeing a lot of ads for Data Science boot camps as an alternative to a traditional 1-2 year masters program, so I decided to investigate.

So I started thinking, I already have a lot of money saved up. I’d like to keep working until I’m in my 60s to at least have something to do. But how much do I actually have to earn? Right now, I’m right around the cusp of breaking six figures (depending on the bonus), but I only spend a relatively small fraction of that.
At work I have a lot of visibility to senior management, and the worst part of my job is being stuck in between the arguments of leadership of different divisions. On Monday we had a 15 minute meeting first thing, my Director announced that she was leaving the company. I relied a lot on my Director to deflect some of the politics and without her, I felt naked. After reflecting a little bit more on my work, I don’t think that I want to keep advancing up this path, because at this point that higher I’d advance the deeper I’d dive into the wonderful world of corporate politics.
I whipped up the minimum work calculator to help me figure this out. Here are the settings that I plugged into it:
I reduced the wage growth a little bit just for a little security.
After a handful of CPU cycles, it spit out $22,400 per year post-tax or something like $24,640 to $26,880 pre-tax. Whoa, it’s lower than my spending, how does that make sense?
Well, the model is making the assumption that my $200,000 in starting investments will grow the first year by $14,501 (principle * e ^(rate * time)) with no withdrawals. The calculator looks at this and says, I could use part of that growth to live off of and still have enough left over to fund my retirement. This is what it ended up doing for year 1 (hover over the result graph to see the numbers).
At the end of year 1 (Age 29):
Spending: $28,700
Post-Tax Income: $22,967
Starting Investments: $200,000
Ending Investments: $207,659
By living off of my investments, I would have needed $5,733 to cover the gap between my income and spending. So in order to fund that income gap, my investment growth was reduced $6,842 to cover the $5,733, plus taxes, and plus loss of investment growth. Now, I would actually never want my spending to exceed my income before retirement, but at least it’s nice to know that I’d have a little leeway.
Here’s the chart that it spit out:
With the results, I feel at least a little better that I would probably be okay if I left my job for whatever reason and found a less stressful one with lower compensation. This minimum amount would be my low bar, so anything over it would mean that I would be able to preserve my standard of living and still retire with more leeway.
Right now, my plan A is to hang on to my current role for as long as possible. If anything happens, Plan B doesn’t look so bad.
Over the last 2 years, I’ve gone viral twice, most recently with a Reddit post that went way beyond my expectations. I had just wrapped up a months worth of work experimenting with some new data on savings rates, and I wanted to show off to /r/DataIsBeautiful. Data is Beautiful is a subreddit where analytical redditors post interesting graphs and charts. The nice thing about Data is Beautiful is that they allow original content, so that people like me (/u/shnugi_) can self post. Most subreddits ban self posting, because it invites a deluge of spam.
I thought that I would get maybe a few hundred people to check out my data and give some constructive feedback. Well, this happened:
The post I had made had attracted hundreds of comments and a Reddit score of 9898. Over ONE HUNDRED THOUSAND PEOPLE visited that day.
I had a plan to be able to support a similar size of visitors as the Lifehacker feature (21k sessions in one day). My plan totally worked, until I completely blew past 21k sessions. After that, my server was throttled for the next few hours. My SO is much better than me at techy things, so I called in the reserves for help. We tried a bunch of things like resizing my Digital Ocean droplet, increasing PHP and MySQL memory limits, and then finally increasing the number of concurrent connections on Apache. The last one fixed the problem for me and my site resumed to normal speed, while also supporting over 1200 active users at the same time.
Hopefully, someone finds this helpful. For me, I know both the times that I’ve gone viral I’ve been highly under-prepared. Good luck to all the other content creators out there!
According to data from the 2015 Consumer Expenditures Survey by the Bureau of Labor Statistics, nearly 38.5% of US households spent more than they earned. Overall, 49.4 million out of 128 million US households are estimated to have had expenditures that exceeded their after tax income (table below). Another 21.1% (27.1 million) of US households saved less than $10,000 per year. One interesting fact is that 8.9% (11.3 million) US households are able to save at least $50,000 per year which is roughly equal to the median US household income.
The original Consumer Expenditures Survey considers retirement contributions as an expense, and even with adjusting those into savings 37.5% of households still spent more than they earned. Recently, there have been many studies reiterating the lack of savings that Americans have on had for emergencies. This data aligns with those earlier views on the poor health of the average American’s finances.
These results are calculated using the 2015 Bureau of Labor Statistics (BLS) Consumer Expenditures Survey (CEX) microdata. The microdata has survey results for a sample of 30,000 US households which are used to estimate the spending and income of the total US population. The data is weighted on a variety of factors by the Bureau of Labor Statistics so that the households sampled model reality. I used the pre-built SAS macro for the 2015 data to merge the interview with the diary files and aggregate expenditures by survey household unit. The interview and diary don’t link on a 1:1 ratio, so I allocated the diary expenditures across each survey household in the interview files. Each survey household was allocated a variable amount from the diary expenditures based on the household unit’s income, expenditures reported in the interview files, and population weight. I also took steps to ensure that the rolled up results still matched the published statistics on the BLS.
Households Unadjusted : 38.5% of US households spent more than they earned in 2015. This was calculated using the CEX total annual expenditure by household. The CEX lumps all retirement contributions (401k, pensions, TSP) into expenditures. Household annual savings calculated as : [Estimated Pre-Tax Income] – [Estimated Taxes] – [Estimated Expenditures]
Households Adjusted : Adjusted for retirement contributions, 37.5% spent more than they earned in 2015. This was calculated using CEX total annual expenditure minus household retirement contributions by household. Social Security is still included in the expenditure values. Household annual savings calculated as : [Estimated Pre-Tax Income] – [Estimated Taxes] – [Total Estimated Expenditures] + [Total Estimated Retirement Contributions].

There are a lot of personal finance related calculators out there, but there are only a handful that I would recommend using on a regular basis. Here are a few of my favorite tools that have easy to use options and clear results.
This rent vs buy calculator balances all the costs you could thing of related to buying a home versus the monthly rental costs. One of this calculator’s great features is that it accounts for the opportunity cost of the mortgage down payment. The opportunity cost is the cost of what you could have earned from that money if you hadn’t bought the house. The calculator also builds in costs to account for rising rent prices, home appreciation, and inflation. Also, the controls are easy to adjust how long you plan on staying and your home price budget. I know it sounds like a lot of options, but if you aren’t sure about one of them just leave it at the default value.
This is my go to retirement calculator. I use it as a simple and quick check to make sure that my savings rates are high enough to meet my retirement goals. The calculator is completely free and doesn’t require registration or anything like that. It automatically does not include Social Security, so you have to manually key in a number for that. In general, I like to pretend that Social Security will be tiny by the time I retire. I just put in $1,000 a month at most ($2,000 if you’re married) for a very conservative estimate of how much SS would actually pay out.
This calculator has pretty similar results to the previous Vanguard one, but it’s tilted more for figuring out how quickly you can retire. I really like the chart on this one, and that it emphasizes controlling spending in order to retire more quickly.
This is a great spreadsheet to help you understand that components of your savings rate in order to calculate it. It’s not as spiffy as some of the other tools, but it’s pretty straightforward and has a very detailed breakdown of how to tally up your income and savings.
