It sounds like an investor’s dream: a 10% gain on your money every year. After all, the stock market’s long-term average annual return often lands somewhere in that ballpark, and many people would be thrilled to see their portfolio go up by 10% per year. Yet, if you take a closer look beneath the surface, you might find that a 10% return isn’t always what it seems—especially when the cost of living is rising just as fast.
The key concept here is understanding the difference between nominal returns and real returns.
Nominal vs. Real Returns
• Nominal Return: This is the return you see on paper—the percentage increase in your investment’s value before you factor in the erosion of purchasing power. For example, if you invest $10,000 and it grows to $11,000 over a year, your nominal return is 10%.
• Real Return: This is the return after accounting for inflation and other factors that reduce what your money can actually buy. If you earn a 10% nominal return but inflation is also running at 10%, your real return is effectively zero. While you might still have more dollars, each one is worth less in terms of goods and services.
How Inflation Eats into Your Returns
Imagine you had $10,000 tucked away, and you ended the year with $11,000. You made a quick mental note: “Great, I’m up 10%.” But if the price of everything around you—groceries, rent, house prices, cars, even stocks—also rose by 10%, then that extra $1,000 doesn’t get you any further ahead in real terms. You can’t buy more groceries, you can’t buy a larger home, and your standard of living hasn’t improved. The purchasing power of your portfolio remained flat despite the seemingly impressive return.
In other words, if all the things you plan to spend money on—today or in the future—have gone up by just as much as your portfolio value, you haven’t actually gained any ground. Your “10% gain” is like running on a treadmill: you’re moving your legs, but you’re not getting anywhere.
The Importance of Beating Inflation
This is why the true measure of an investment’s success isn’t simply how much it returns in nominal terms, but how well it does relative to inflation and other measures of value.
• Beating Inflation: For your return to hold genuine value, it needs to outstrip inflation. If inflation runs at 10% and you earn a 12% return, your real return is about 2%. You’re now able to buy more goods and services than you could before. That’s a real increase in wealth.
• Comparing Asset Classes: If gold, houses, the S&P 500, or any other asset class are only returning 10% in a world where the currency itself is losing value at 10%, none of them are truly generating additional wealth. They’re merely treading water. To come out ahead, you need investments that grow faster than the overall rise in prices.
Real-World Consequences
Focusing on real returns is critical for long-term financial health:
1. Retirement Planning: If you base your retirement strategy on nominal returns, you might end up with less purchasing power than expected when the time comes to spend that money. Real returns help you estimate how much you’ll truly be able to afford in retirement.
2. Goal Setting: Whether it’s buying a home or sending your kids to college, you need your investments to beat the rising costs of those goals. If your returns only keep pace with inflation, the finish line never gets closer.
3. Portfolio Strategy: Once you grasp the importance of beating inflation, you can seek out assets and strategies that offer higher real returns. This might mean diversifying into inflation-resistant assets, looking for growth opportunities in emerging markets, or holding a portion of your savings in investments that historically maintain their purchasing power over time.
The Bottom Line
A 10% annual return might look good on paper, but if the world around you—housing, stocks, commodities, and everyday costs—has also gone up by 10%, that “return” isn’t doing you much good. You’re not actually richer; you just have more dollars that buy the same (or less) as before.
In a world of monetary expansion and rising prices, the goal is to earn a return that’s meaningfully higher than the rate at which money is losing value. The true “good” return is the one that allows you to buy more of what you want over time, not just see a bigger number on your account statement.
