Planning for retirement can feel overwhelming, but calculating the corpus you need is simpler than it seems. By assessing your current expenses, factoring inflation, estimating your retirement horizon, and considering investment returns, you can chart a clear path to financial security post-retirement.

Retirement planning is crucial to ensure a comfortable and worry-free life after you stop working. The central question many face is: How much money will I need? The answer lies in a step-by-step calculation based on your current lifestyle and future expectations.

Notable updates for effective retirement planning:

Start with monthly expenses: Begin by listing your present monthly spending—for example, groceries, utilities, transport, healthcare, and lifestyle. If you currently spend around ₹50,000/month, remember this might shift post-retirement due to changing needs.

Factor in inflation: Inflation erodes purchasing power. With an average inflation rate of 6%, expenses double roughly every 12 years. So, ₹50,000 today may become about ₹1.6 lakh in 20 years, which is a more realistic monthly budget at retirement.

Consider retirement duration: Indian life expectancy is increasing. Planning for 20-25 years post-retirement is prudent. For a monthly expense of ₹1.6 lakh, your annual need is around ₹19-20 lakh. Multiplying this by 25 years points to a corpus near ₹5 crore.

Use the 4% withdrawal rule: Financial experts advise withdrawing 4% of your retirement corpus annually to sustain it over time. This ‘financial freedom number’ can be approximated by multiplying yearly expenses by 25.

Build corpus via disciplined investing: Start early and save regularly through diversified instruments like mutual funds, National Pension System (NPS), and Public Provident Fund (PPF). Systematic Investment Plans (SIPs) especially help accumulate wealth leveraging compounding.

Review and adjust: Periodic evaluation of your portfolio, expenses, and inflation assumptions is essential to stay on track.

Leverage retirement calculators: Online tools (from Moneycontrol, Groww, SBI Securities etc.) help model your corpus based on your inputs, making planning precise and dynamic.

In essence, retirement corpus planning combines realistic expense estimation, inflation adjustment, longevity outlook, and intelligent investing to unlock financial freedom.
