I work in an industry where it is pretty well known that if you want to make money, you need to jump companies.  In fact, I heard this about my company before I even started working for them!  Well, for me and my group of friends, that first round of “QUIT QUIT QUIT QUIT!!!” is happening now. 

We’ve all been working for about 3 years, and of my group of 15-20 friends, 6 have quit in the last 5 months reaping new salaries 15-35% higher!  For comparison, our company’s average annual raise is around 4%.  How much “better” (financially speaking) are my quitting friends doing?

Let’s take a typical example.  Jon and Sam are making 60k a year each.  Jon decides to quit for greener pastures in the form of a 10k raise.  Sam decides he wants to stick it out, earning an average 4% raise.  The question is: how long does Sam need to work before he will be making the same money as Jon?  The quick answer might be that, well, a 10k raise is roughly a 17% raise.  Therefore, it will take Sam about 4 years before his 4% raises add to up 17% (Sam will be making 70.2k a year after 4 4% raises).  So, we might say Jon jumped Sam by 4 years in terms of salary by quitting.  Well, while sitting my cube two days ago, I came to realize how wrong the above argument is!  There is that little thing called inflation… and results just might make you sick.

The first thing I realized is that when we talk about salaries, what we usually mean is “buying power.”  And the difference between the two is inflation.  So back to Jon and Sam, yes, Sam will make 70k in 4 years, but that 70k in 4 years can buy less than that 70k can now.  It has less buying power (again, inflation).  So, back to our original question with this in mind: how long will it take for Sam to make the same buying power as Jon got right now by quitting?

The trick is to take into account inflation.  One easy way to do this is to speak about all money in “today dollars.”  This is also most convinient because we have a good feel for what today’s dollar is worth.  This is easily accomplished by simply subtracting inflation from any future growth.  This is a common technique is financial analysis.  If a fund earns 8% this year, its “true” earning is really 5% (subtract off 3% for average inflation).  Well, the same can be done with raises.  If Sam gets a 4% raise next year, his buying power only really increases by 1% since the cost of goods and services has inflated 3%.

By thinking about everything in today’s dollars, Jon’s choice to quit starts looking even better.  Recognizing that Sam’s buying power only increases by 1% each year, it will take him 16 years before he has the same buying power as Jon has right now.  That’s the difference between someone in their mid 20s and someone in their early 40s.  I have to say, my non-quitter friends at work were not amused by this result!  Here are some other interesting results:

 - If you make 50k now, and average 4% raises, it will take 70 years before you have the buying power of today’s 6 figure salary (you would be 92 years old if you started working at 22)

 - If you make 50k now and you get 6% raises on average, it will take 24 years before you have the 6 figure buying power

 - It will take 14 years of receiving 4% raises to match the buying power of a single 15% raise now

I have plugged these relationships into a simple spreadsheet in case anyone wants to run their own numbers.  It is pretty straight forward.  Next to each year is a toggle for allowing a larger raise (say, a promotion). A “1″ will indicate a “promotion” raise for that year while a “0″ indicates an “average” raise.  Enjoy, and happy job hunting.  =)
