It’s back-to-school season, which means you’re about to be inundated with tips on saving money on backpacks, laptops, and No. 2 pencils. But not in a Money Matters newsletter; that’s not how we roll.

I should probably apologize to my Britannica colleagues before I say this, but much of what I learned in school has gone by the wayside. Like money in a flexible spending account, my brain functions on the “use it or lose it” system. I can calculate a bond yield in my sleep—it’s part of what I do for a living—but I don’t remember all of the Spanish verb tenses nor how to solve a polynomial equation.

That’s not to say that school was a waste of time. It’s about “learning how to learn,” as the saying goes. Ask questions, think before you act, and if you show your work, you might get partial credit. Those habits never expire—and they’re just as valuable when you’re making financial decisions as they were when you were taking tests.

School did a pretty good job of teaching us how to approach problems. It just didn’t always tell us which problems we’d be solving later in life.

Nobody hands you a worksheet explaining why one health insurance plan costs more than another or how to weigh the higher premiums against lower deductibles and co-pays. There’s no multiple-choice quiz on whether to choose a traditional or Roth 401(k), or how to allocate it among stocks, bonds, and alternative investments. And unlike school, you often don’t get your grade until many years—or decades—later.

The good news is that you don’t need a financial degree to solve those problems. You just need to dust off a few habits you probably learned long before you opened your first bank account. The same skills that helped you work through a math problem, write a research paper, or prepare for a final exam can also help you become a better saver, investor, and financial decision-maker.

Cramming is a great way to pass a test and a terrible way to build lasting knowledge. The same is true in personal finance. Knowing today’s rules may solve today’s issues. Understanding the principles behind them will help you solve tomorrow’s, too.

For example, do you know the current tax brackets and the income thresholds for each? I don’t, which is fine because they change over time anyway. But I do know—and you should, too—that it’s a progressive tax system, meaning higher levels of income are taxed at progressively higher rates. And when you move into a higher bracket, higher taxes are paid only on your income earned above the previous bracket’s threshold. Once you grasp the concept, you don’t need to memorize the numbers. You know where to find them, how to interpret them, and how a raise, Roth conversion, or retirement withdrawal might affect your tax bill.

Here’s another: You don’t need to memorize the current federal funds rate and be glued to the TV ahead of the next interest rate decision. You do, however, need to understand that different interest rates serve different purposes. The Fed directly controls one very short-term interest rate that banks charge one another for overnight loans. Other rates—from long-term mortgages to Treasury bonds, notes, and bills—are determined in financial markets, where investors weigh inflation, economic growth, and the demand for credit. That’s why a Fed rate cut doesn’t automatically send mortgage rates lower, nor a rate hike send them higher. Once you understand those relationships, the headlines become a lot easier to interpret. 

We like to think of back-to-school season as a fresh start. But when it comes to money, there are no semesters, no midterm exams, and no graduation ceremony. The lessons keep coming—and so do the opportunities to learn from them.
