Comparing the risk of investing and the risk of not investing
Opportunity cost: what you lose by not investing
When you leave money idle, you pay a invisible priceloss of purchasing power. Imagine R$ 10,000 in the drawer; with inflation, That amount will buy less in five years' time.
To better understand how inflation is measured, take a look at the Explanation of inflation and purchasing power. This is opportunity cost - what you miss out on by not investing.
A quick example: waiting for “the perfect moment” and watching years go by while your money loses value.
How returns and inflation affect your purchasing power
What matters is the difference between return e inflation. If the return is lower than inflation, you lose purchasing power; if it's higher, you grow.
Practical formula: future purchasing power ≈ current value × (1 return) / (1 inflation).
Illustrative table (approximations, 5 years, R$ 10,000):
| Scenario | Annual return | Annual inflation | Results in 5 years |
|---|---|---|---|
| Saving / not investing | 0% | 4% | R$ 8,240 (lower purchasing power) |
| Moderate investment | 5% | 4% | R$ 11.046 (small real gain) |
| Aggressive investment | 8% | 4% | R$ 13,680 (higher real gain) |
Even a modest gain above inflation preserves your purchasing power. Volatility exists, but the inflation erodes your capital if you don't act - that's why it's important to know more efficient alternatives for your money, such as those suggested in where to put your money now.
