๐ฏ Which One Is Best for You?
There’s no universal answerโthe best investment depends on your goals, timeline, and risk tolerance.
๐ Ask yourself:
-
Do you have an emergency fund? โ Start with fixed income
-
Can you leave the money invested for years? โ Explore variable income
-
Do you want to protect your money from inflation? โ Consider Tesouro IPCA or strong stocks
๐ง Strategy: Combine Both
A balanced portfolio usually mixes fixed and variable income assets.
Example allocation:
-
70% fixed income for safety and liquidity
-
30% variable income for growth and long-term potential
๐ This diversification helps reduce risk and increase potential returns over time.
โ Conclusion
Understanding the differences between fixed and variable income is the foundation of smart investing.
By combining both according to your profile and goals, youโll be better prepared to build wealth, protect your money, and achieve your financial dreamsโwhether that’s traveling, buying a home, retiring early, or becoming financially free.
