What If You Invested $10,000 Every Year For the Last 10 Years? 2007-2016 Edition

Instead of just looking at one year of returns, here’s an annual exercise that helps you look at the bigger picture. You may know the 10-year historical return of the S&P 500, but most of us didn’t just invest a big lump sum of money in 2007, and most of us don’t just invest in the S&P 500.

Investment benchmark. There are many possible choices for an investment benchmark, but I chose the Vanguard Target Retirement 2045 Fund. This all-in-one fund is low-cost, highly-diversified, and available in many employer retirement plans as well open to anyone with an IRA. In the early accumulation phase, this fund is 90% stocks (both domestic and international) and 10% bonds (investment-grade domestic and international). I think it’s a solid default choice where you could easily do worse over the long run.

Investment amount. For the last decade, the maximum allowable contribution to a Traditional or Roth IRA has been roughly $5,000 per person. (It was $4k in 2007, but has been $5k or higher since.) That means a couple could put away at least $10,000 a year in tax-advantaged accounts. If you have a household income of $67,000, then $10,000 is right at the 15% savings rate mark.

A decade of real-world savings. To create a simple-yet-realistic scenario, 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. You’d have put in $100,000 over time, but in more manageable increments. With the handy tools at Morningstar and a quick Google spreadsheet, we get this:

In this case, I would say that ending up with a gain of over $50,000 for every $10k annual investment is nothing to sneeze at. If you put in $20k every year, your gains would have been over $100,000. Some of that money was invested right before the crash in 2008, and some has only been in the market for a few years. Not every year will have turned out to be a great year to invest, but taking it all together provides a more calm, balanced picture.
