A retirement plan is a comprehensive financial strategy designed to ensure a comfortable and secure lifestyle during an individual's post-employment years. It typically involves setting aside a portion of one's income into retirement savings accounts, and making investment choices to grow those savings over time. Retirement plans can be employer-sponsored or paid by individual contribution. Some jurisdictions have compulsory retirement plans that both employers and employees have to contribute into, like Malaysia's Employees' Provident Fund (EPF) and Singapore's Central Provident Fund (CPF).
