How much money you really need for retirement depends on your lifestyle, living costs, and future goals. Key factors include daily expenses, healthcare needs, inflation, and how long you expect retirement to last. A common guideline is to aim for 70–80% of your pre-retirement income to maintain a comfortable lifestyle. However, personal choices like travel plans, home ownership, and dependents can change this number. Regularly reviewing your savings, investments, and retirement plans helps ensure you stay on track. Starting early and investing consistently can make achieving your ideal retirement corpus more realistic and stress-free.
