A Great Moment To Build Wealth: Hold Expenses Steady When Income Rises

A common psychological trait that most people share is a desire to experience forward progress—the harnessing of that trait, after all, is one of the reasons why it is much easier to stick with an income investing strategy over long periods of time.

If you own a diversified basket of assets, and contribute to it regularly, and reinvest, it is almost guaranteed that you will increase your income year after year, seeing the wealth-building process unfurl before your eyes. Someone who judges himself according to the amount of income that his household income each year will experience the psychological satisfaction of seeing the amount of income that his household generates go up year after year, whereas it’s hard to craft a strategy that builds wealth over the long haul while also allowing you to see your net worth increase in a year like 2009.

For better and often worse, most people also associate spending more with progress. And when you have to go backwards, a lot of bad emotions like resentment, anger, and frustration start to creep in.

If I told you that a couple was moving from a $250,000 house into a $500,000 house while another one was moving from a $500,000 house into a $250,000 house, and you had to guess which couple would get divorced within the year, which one would you bet on?

Obviously, there are a lot of good reasons why people successfully purchase smaller homes, and there’s a lot of people who bite off more than they can chew with their home purchase decisions that can lead to financial difficulties and fighting. But there’s also a lot of people who would associate the downsizing with going backwards in life and it would lead to heartache that could have been avoided.

A great technique in the wealth-building process is to try and keep household spending constant, or at least increasing at a slower rate, than the changes in household income. If you’re spending $50,000 per year and see your household income rise from $70,000 to $80,000, good things can happen when you take that extra $10,000 and invest it.

That’s the funny thing about writing about investing so much—even though I spend a lot of time here talking about individual stocks and particular investments to make, what’s really important is your household savings rate. That’s going to determine your future much more than the particular success that you have in the aggregate with your stock-holdings.

If your household saves $300 per month and earns 10% for thirty years, you end up with $678,000 at the end of the period. If you get your savings rate up to $600 per month for thirty years, you only have to earn 6.7% to end up with that same $678,000. In terms of how you allocate your energy, most people are going to get more bang for their buck finding a way to increase the amount of their household savings rather than trying to find a way to get that extra percent on investment returns.

In the financial writing sphere, frugality is a very popular topic right now—it’s all about cutting costs. But handled wrongly, and it can be associated with a deprival lifestyle. If I had to pick my style of how to save $10,000, I’d rather do it by increasing my income $10,000 than by reducing my expenses by $10,000 (although from a tax point of view, reducing expenses is almost always more efficient). Sure, root out the ridiculous expenditures from your budget, and take a hard look at recurring monthly expenses that may be unnecessary, but I think the most psychologically satisfying way to do it is by deliberately structuring your life so that when more money comes in, you keep your focus on holding expenses steady and resisting the impulse of lifestyle inflation.

    I have a real life example of what you are talking about.  When the company that I work for first offered a 401k, my wife and I were already in a house with a mortgage and a relatively consistent cost of living.  For the first 3 or 4 years after the 401k became available, I put my annual raise in as a pretax contribution.  So, it acted as if I didn’t get a raise for that period of my life, but I hit the maximum contribution rate is a relatively short period of time with little pain (we didn’t have to rein in our expenses, just keep them from growing).
    Thanks for the thought starters.

    This was a fantastic post in general which started off with an exceptional title. I was in sales for 31 years with an extremely variable income. The conclusion I came to early on while supporting a family of 5 was first to determine a base level of expenses. Any year where income exceeded what i needed to make to pay those expenses I had an explicit goal of saving 90% of the after tax income above that amount. Sure, take 10% of it and treat the family to whatever, but understand the job may not always be that good and plan for the inevitable rainy day.

    On the topic of frugality I wondered if you saw the Barron’s article in the last week about the 97 year old Buffalo, NY lady who had accumulated $5-6mm while never having earned more than (I think) $23,000 a year? Just an amazing story.

    ddh81 The Oracle of Buffalo! Looks like Barron’s has me beat when it comes to titles. 

    I’m just now reading it–thanks for bringing it to my attention. 

    It’s a shame that: 

    (1) She turned it over to a finance advisor, even though I reluctantly get it because of her age. 
    (2) Articles about successful do-it-yourself investors are written about in such patronizing tones. 

    However, I really liked the story about her Medtronic investment. Amazing what you can do for yourself when you just continue to hold on.
