Futureproofing: Compound Interest Is Your Frenemy



First, an apology for using the term "frenemy." I hate this word but find it useful for this post.

What is compound interest? From our friends at Wikipedia: Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on interest. How does it work? With stunning efficiency. For instance, if you have an interest-bearing savings account, compound interest is your friend, as your banking institution will pay interest (albeit a minisule amount these days) on the principal dollar amount. Over a long period of time, compound interest is earned on both the principal and accumulated interest, eg $100 principal + 5% interest = $105.00. Left untouched, your next round of 5% interest will be paid on the $105.00 balance, resulting in a sum total of $110.25. This is a simple (and unrealistic, in terms of interest paid) example of money making money.

If, however, you have debt on an interest-bearing loan, compound interest if your enemy. The kind of enemy that doesn't just want to conquer you, but humiliate before devouring your flesh and enslave your family kind of enemy. Suppose you have a credit card with a $1000 balance (see what I did there, with the debt being 10x the savings used in the previous example?) and an interest rate of 15%. After applying interest, your balance will be $1150.00; left unpaid, this will balloon to $1322.50 and so on. This doesn't begin to take into account late fees, etc. And your minimum payment? 2-3% of the balance, in many cases, but in ALL cases, much less lower than the interest rate. Lenders are betting you will run up a balance, then pay it off over time, which allows compound interest to do its dirty work. Avoid when possible.

I'll close with a quote from Albert Einstein: “Those who understand interest earn it, those who don’t, pay it.”

Regarding Keeslyn

In January 2020, a young lady named Keeslyn Roberts disappeared from a fuel station near my home. The case remains unsolved. This post will examine the actions, and lack thereof, of those in authority, and how this contributes to the case remaining unsolved. But first, a little backstory. As a teen, I lived in the same neighborhood as the Roberts family. Keeslyn's father, Eric, is older than I, and I don't recall the two of us having much interaction. His sister, on the other hand, is the same age and we've been friends for over 40 years. It was she who told me about Keeslyn's disappearance and the family's frustrations with the lack of police action. To learn more of the specifics of the case, numerous podcasts and news stories are available online. To my understanding, the police reaction to the disappearance has thus far been little to no reaction. After no word from his daughter for several days, Eric went to the fuel station where her car was parked. He th...

Visiting Alice

Savannah, Georgia is one of my favorite cities. Younger than London, older than San Francisco, with a degree of quirk rivaled only by New Orleans, Savannah is a six hour (if Atlanta traffic is agreeable) drive from my home in the northwestern corner of the state.  Comparing my region with that of Savannah is an exercise in futility; they are worlds apart. One is lower Appalachia, with rolling green hills and valleys, creeks and waterfalls. The other is coastal Georgia, low country, wetlands. Even the cultures and accents are sufficiently different as to make a new acquaintance appear surprised when they ask where you're from and you reply "Georgia." Something neither place lacks is ghosts, but you probably knew that, didn't you? View this YouTube video by Dixie After Dark for a bit of info on Georgia's first ghost, Alice Riley. I love writing about Savannah. I can almost see the Spanish moss and smell the pot of low country boil!

How To Beat A Billionaire - Updated

If you've spent any time at all on this site, you will have noticed I have an interest in investing. I had no interest in finance until my mid-40s, when I took a job at a printing company in which one of the partners is a CPA. I learned personal finance the hard way, struggling with credit card debt in my early 20s (it was the 90s; I blame the guitar and camera stores). After digging myself out of the hole I was in by age 27, I was cautious to avoid debt anytime I could. Investing, aside from employer retirement plans, was not on my radar. Fatherhood really spurred me into action when it came to investing. There's simply no way a savings account can outpace inflation; if you want to thrive financially, investing is the best way to get ahead. So, with encouragement from my boss, I began to study and learn. Investopedia and The Balance proved to be immensely helpful. In time, I opened an account and started buying exchange traded funds (ETFs) and was on my way. I read a few...
