Instead of only looking at year-to-date or last year’s return numbers that are often quoted in the media, I also like to take a longer-term perspective (especially on down years). How would a steady investor have done over the last decade?

Target date funds. The Vanguard Target Retirement 2045 Fund is an all-in-one fund that is low-cost, globally-diversified, and available both inside many employer retirement plans and to anyone that funds an IRA. When you are young (up until age 40 for those retiring at 65), this fund holds 90% stocks and 10% bonds. It is a solid default choice in a world of mediocre, overpriced options. This is also a good benchmark for others that use low-cost index funds.

The power of consistent, tax-advantaged investing. For the last decade, the maximum allowable annual contribution to a Traditional or Roth IRA has been roughly $5,000 per person. The maximum allowable annual contribution for a 401k, 403b, or TSP plan has been over $10,000 per person. If you have a household income of $67,000, then $10,000 is right at the 15% savings rate mark. Therefore, I’m going to use $10,000 as a benchmark amount. This round number also makes it easy to multiply the results as needed to match your own situation. Save $5,000 a year? Halve the result. Save $20,000 a year? Double the numbers, and so on.

The real-world payoff from a decade of saving $833 a month. What would have happened if you put $10,000 a year into the Vanguard Target Retirement 2045 Fund, every year, for the past 10 years? With the interactive tools at Morningstar and a Google spreadsheet, we get this:

Investing $10,000 every year ($833 a month, or $384 per bi-weekly paycheck) for the last decade would have resulted in a total balance of $145,000. That’s $100,000 in steady contributions and $45,000 in investment gains.

It gets even better over time. There is a popular example of the power of compound interest that shows how someone who started saving at age 25, saves and invests for 10 years but then stops and never saves a penny again still beats someone who starts saving at 35 and keeps on saving for 30 years. Acorns provides a nice illustration:

The “Rule of 72” shows us that with just 7.2% annual returns, your money will double every decade from now on. After another 10 years, every $100k will be $200k. After another 10 years, that $200k will be $400k. Once you have that initial momentum, it just keeps going.

Here are my previous “saving for a decade” posts:

Bottom line. Saving now can be hard, especially when you see your investment balances drop. But over time, with consistency and starting early, things smooth out. You can truly build serious wealth with something as accessible and boring as an IRA/401k plan and a Vanguard Target Retirement fund (or a simple collection of low-cost index funds).

  1. It’s nearly impossible to include in an example but what also really turbocharges real world performance is that prudent investors generally are also going to significantly grow their income, mine more than doubled each ten year period of my career to the point that the amount I invested not only filled up every available qualified retirement plan but a lot of taxable investments. I eventually was investing over 50% of my gross income because we did not let our lifestyle costs increase as fast as our income did. That makes for a lot of growth even though much of that doesn’t have as many years to compound. Very clear presentation of personal finance issues everyone needs to understand.

  2. Last years edition was so much more inspiring! For someone who started investing in 2013 this is their first best market. Keep on keeping on and you’ll be shocked at what you have come 2033.
