A retirement fund is a financial account designed to help individuals save money for their retirement years. It allows people to set aside a portion of their income, which can grow over time through investments. Common types of retirement funds include 401(k) plans, IRAs, and pension funds. These funds often provide tax advantages, encouraging individuals to save more for their future. Contributing to a retirement fund is essential for financial security in later life. As people age, they may rely on these savings to cover living expenses, healthcare, and leisure activities. Planning ahead and regularly contributing to a retirement fund can help ensure a comfortable and stable retirement.
