It doesn’t matter how you look at it, specialty coffee is a waste of money. Which is why I wonder, why does arguably one of the brokest first world demographics, the student, waste so much money on it? Kevin O’Leary has said it before, and I’m going to break it down by the numbers. Suppose 5 days a week, you buy Starbucks, averaging $5 a day, or $25 a week. You do this throughout the school year, which is about 34 weeks a year. This ends up being about $850. $850 might not sound like a whole lot initially, but once you calculate this for 4-5 years of schooling, and then add the interest you could have made if you decided to put it into a retirement fund.

Suppose you invested this $3400 into a S&P 500 index fund which averages a return year-over-year of about 10.5%. If you let your $3400 in Starbucks money ride in that fund for a few decade, the rewards could be quite worthwhile.

After 40 years, you’d be looking at a value of $184,000 minus inflation of about $7500. Scale that up to 60 years, that’d be $1,347,832 after inflation. Investing early in an index fund and letting it ride for life is worthwhile if you have the patience. 20 years from now when you decide to get started with an investment in a fund, the rewards will be a fraction of that.
