How the Retirement Calculator Works

The Retirement Calculator helps you estimate how much money you need to live comfortably after retirement. It considers your current age, monthly expenses, inflation rate, expected return on investment, and retirement age to project your required retirement corpus — the total amount you’ll need to sustain your lifestyle.

Field Explanations

• Current Age: Your present age helps the calculator determine how many years you have left until retirement. For example, if you’re 30 and plan to retire at 60, you have 30 years to build your retirement corpus.
• Monthly Expenses (₹): The amount you currently spend per month. This will be adjusted for inflation to estimate your post-retirement expenses.
• Expected Inflation Rate (%): Average rise in cost of living. Typically, India’s long-term inflation is around 6–7%.
• Expected Return Rate (%): The annual return you expect on your investments (e.g., 10–12% for equity SIPs, 7–8% for balanced funds).
• Retirement Age: The age at which you plan to retire — commonly 58 or 60 years.
• Life Expectancy: Helps estimate how long you’ll need your corpus to last (e.g., 80–85 years).

Example Calculation

Let’s assume you’re 30 years old, and your current monthly expense is ₹50,000. You plan to retire at 60, expect an inflation rate of 6%, and a post-retirement return of 8%.

By the time you retire, your expenses (adjusted for inflation) will rise to around ₹2.87 lakh/month. To sustain this lifestyle for 20 years post-retirement, you’ll need a corpus of approximately ₹6.2 crore.
