LOUIS, MISSOURI — Finance types love to talk about Internal Rate of Return (IRR) and Net Present Value (NPV). They’re the bread and butter of capital budgeting, the go-to tools for deciding whether an investment is worth the risk.
But what if I told you that IRR and NPV are more than just financial metrics? What if they were actually profound life lessons hidden in spreadsheets?
Now, before you roll your eyes, and accuse me of turning human existence into an Excel function (which, let’s be honest, some of you do with your finances), hear me out. These concepts aren’t just for Wall Street analysts—they offer a surprisingly insightful framework for making decisions in love, careers, and even those existential crises we all love to ignore.
IRR: Seductive illusion of high returns
First, let’s talk about IRR, the flashy, attention-seeking metric of finance. IRR represents the rate at which an investment breaks even in today’s money, making it seem like a great way to compare opportunities. Higher IRR? Better investment. Simple, right? Wrong.
In life, we often chase high IRR decisions—the jobs that pay more upfront, the relationships that feel electric from day one, the projects that promise instant success.
But IRR can be misleading. It doesn’t account for scale (a 50 percent return on P10 isn’t as good as a 10 percent return on P1 million), nor does it consider long-term sustainability.
Ever taken a job just because it paid well, only to realize months later that you’re miserable? That’s IRR deception.
The returns looked fantastic in theory, but the underlying investment (your happiness, growth, and sanity) was fundamentally flawed.
High IRR decisions often come with hidden costs—burnout, disillusionment, regret. And much like that too-good-to-be-true startup promising 300 percent returns, they tend to crash spectacularly.
NPV: Metric of true value
Which brings us to NPV, the more thoughtful, mature sibling of IRR. NPV looks at the total value an investment will generate over time, discounting future cash flows to their present worth. It forces you to ask: Is this really worth it, given all factors—effort, time, risk, and opportunity cost?
Think of NPV as the metric for life’s best decisions. Taking a lower-paying job that offers career growth? That’s a solid NPV move. Staying in a relationship that deepens over time rather than fizzles after the honeymoon phase? Another great NPV play. Moving to a city where you don’t know anyone but have immense room to grow? High upfront costs, but potentially game-changing long-term NPV.
The problem? Humans are impatient. We want the IRR thrill, not the NPV wisdom. We chase short-term gratification at the expense of long-term value.
But ask any seasoned investor, and they’ll tell you: The best decisions aren’t about quick wins. They’re about compounding returns over time.
Life’s discount rate
One of the sneaky factors that affects both IRR and NPV is the discount rate—the percentage by which we devalue future benefits.
In finance, a higher discount rate means you prioritize today’s cash over tomorrow’s. In life, it means you undervalue patience, persistence, and delayed gratification.
Have you ever quit a pursuit too early because the payoff seemed too far away? Abandoned a passion project because results weren’t immediate? Ended a relationship because it required effort to deepen?
That’s a high discount rate at work. You’re effectively saying, “‘Future me’ doesn’t matter as much as ‘present me’.”
But here’s the kicker: ‘Future you’ is coming, whether you like it or not. And they’re going to be really annoyed at you for making choices based purely on short-term convenience.
Making peace with imperfect calculations
Of course, life isn’t a perfect spreadsheet. Some investments—whether in love, career, or personal growth—defy neat calculations. There will always be unknown variables, unexpected risks, and those baffling scenarios where the numbers say “no” but your gut says “yes.”
But that’s the beauty of it. IRR can help us spot alluring but ultimately-flawed decisions. NPV teaches us to think long-term. And our own personal discount rate reminds us to balance living for today with investing in tomorrow.
So the next time you’re faced with a major life decision, take a page from finance: Don’t just chase the flashiest returns. Look at the big picture, assess the true value, and invest wisely. Because in the end, the best investments aren’t just the ones that make money—they’re the ones that make a life worth living.
