Investing is the act of allocating money, time, or resources to an asset with the expectation of generating a return or benefit in the future.
Investment mathematics
Simple interest It is calculated on the initial principal and is useful for loans and basic savings accounts. Basic formula: interest equals principal times rate times time. It is ideal for understanding how much is earned without reinvesting the interest.
Compound interest It is the interest calculated on the initial principal plus the interest accumulated in previous periods, which produces exponential growth over time. It is essential for long-term investments and for products such as funds and deposits with periodic compounding.
Inflation Inflation represents the general rise in prices that reduces the purchasing power of money. When planning investments, it is crucial to consider inflation to preserve the real value of capital.
Prerequisites Before investing, it is advisable to have an emergency fund equivalent to one year of expenses to cover unforeseen events and adequate insurance coverage to protect against accidents, illnesses, or loss of income.
Common investment products Savings accounts These are basic bank accounts that generate interest on deposits. Often simple method and modest rates.
Fixed-term deposits These are term deposits that offer higher rates in exchange for locking up the money for a specific period. Strategies such as laddering allow staggering maturities and improving liquidity. There are automatic sweep options that move surplus balances into deposits to obtain higher returns.
Recurring deposits They allow contributing a fixed amount periodically and usually benefit from compound interest. They are suitable for disciplined saving and planning financial goals.
