Retirement Calculator

1. Introduction

Planning for a secure and stress-free retirement starts today. With our Retirement Calculator, you can estimate the total corpus you’ll need after you retire, based on your current lifestyle, inflation, and expected returns. This powerful tool helps you understand how much you should save and invest now to maintain your standard of living after retirement.

Whether you’re in your 30s, 40s, or 50s, this calculator gives you a clear roadmap to achieve financial independence in your golden years.

2. What is a Retirement Calculator?

A retirement calculator is a tool that estimates the amount of money you need to accumulate by the time you retire, so you can cover your post-retirement expenses for the rest of your life. It factors in:

• Your current age and retirement age

• Monthly expenses

• Inflation over time

• Expected rate of return on your investments

• Number of years you expect to live after retirement

The output is the required retirement corpus, which is the amount you need at the time of retirement to meet your future needs.

3. Why is Retirement Planning Important?

Retirement is a stage of life where regular income stops but expenses don’t. With rising life expectancy and medical costs, financial preparedness is essential. If you don’t plan adequately:

• You may outlive your savings

• You’ll be dependent on others

• Your quality of life may deteriorate

With early planning and tools like the Retirement Calculator, you can avoid these risks and build a future where you are financially self-sufficient.

4. Formula Used in This Calculator

This calculator uses the Future Value of Expenses and Present Value of Annuity formula to compute the required corpus:

Step 1: Estimate Future Monthly Expense at Retirement

Future Expense = Current Expense × (1 + i)n

Where:

• i = inflation rate

• n = years until retirement

Step 2: Convert Monthly Expense to Annual

Annual Expense = Future Expense × 12

Step 3: Calculate Required Corpus at Retirement

Corpus = Annual Expense × [(1 – (1 + r)-t) / r]

Where:

• r = expected return rate

• t = years post-retirement

This ensures that you never run out of money if you withdraw the inflation-adjusted expense annually from your retirement fund.

5. Example Calculation

Let’s say:

• You are 30 now and plan to retire at 60

• Your current monthly expense is ₹30,000

• Inflation rate = 6%

• Expected return after retirement = 8%

• You expect to live 25 years post-retirement

1. Future Monthly Expense at 60

   = ₹30,000 × (1 + 0.06)30

   = ₹1,72,590 (approx)

2. Annual Expense = ₹1,72,590 × 12 = ₹20,71,080

3. Corpus Needed = ₹20,71,080 × [(1 – (1 + 0.08)-25) / 0.08]

   ≈ ₹2.2 Crores

You will need around ₹2.2 Crores at retirement to sustain your lifestyle for 25 years.
