Retirement Calculator

Retirement Calculator

The Retirement Calculator helps you determine exactly how much corpus you need to retire comfortably and the monthly SIP required to build it. With rising life expectancy, increasing healthcare costs, and persistent inflation, retirement planning has become one of the most critical financial goals for every working individual. This calculator factors in your current age, target retirement age, monthly expenses, inflation, and expected returns — giving you a complete, personalized retirement roadmap.

What is a Retirement Corpus?

A retirement corpus is the total accumulated wealth you need at the time of retirement to sustain your lifestyle for the rest of your life without depending on active income. It acts as your personal pension fund — generating returns that you withdraw from periodically after retiring.

For example, if you currently spend ₹50,000 per month and plan to retire in 25 years, your monthly expenses at retirement — after accounting for 6% annual inflation — will be significantly higher. The retirement corpus must be large enough to fund these inflation-adjusted expenses for 25+ years of post-retirement life.

How Does the Retirement Calculator Work?

The calculator takes eight key inputs and processes them in two phases:

• Accumulation phase: From today until you retire, your existing savings grow at the pre-retirement return rate and you contribute a monthly SIP to build toward the required corpus.
• Distribution phase: After retirement, your corpus must generate enough income to fund your inflation-adjusted expenses from retirement until your life expectancy — while earning a conservative post-retirement return (typically from debt funds, FDs, or SCSS).

The result is a precise required corpus figure and the exact monthly SIP you need to start today to reach that goal.

Benefits of Using This Calculator

Inflation-Adjusted Planning

Unlike basic savings calculators, this tool accounts for inflation in two ways: it inflates your current expenses to project future monthly needs, and it factors in both pre- and post-retirement return rates to compute a realistic corpus requirement.

Accounts for Existing Savings

If you already have ₹5,00,000 or more saved in EPF, PPF, or mutual funds, the calculator credits the future value of that amount — reducing the gap you need to fill with new SIPs.

Personalized SIP Recommendation

The monthly SIP output is tailored specifically to your inputs — not a generic rule of thumb. This makes it far more actionable than broad advice like "save 15% of your income."

Real-World Example

Suppose you are 30 years old, want to retire at 60, and currently spend ₹50,000 per month. With 6% inflation, your monthly expenses at retirement will be approximately ₹2,87,175. To sustain these expenses from age 60 to 85 (25 years), while earning 7% post-retirement returns, you would need a corpus of roughly ₹4,00,00,000. With existing savings of ₹5,00,000 growing at 12%, the gap you must build through monthly SIPs shrinks — but still requires disciplined contributions over 30 years.

Key Factors That Affect Your Retirement Corpus

• Inflation rate: Even a 1% difference in assumed inflation can change your required corpus by 20–30%. India's long-term average inflation is 5–7%.
• Retirement age: Retiring at 55 vs. 60 means 5 fewer years of accumulation and 5 more years of withdrawals — dramatically increasing the required corpus.
• Life expectancy: Planning conservatively to age 90 is safer than 80, especially given improving healthcare.
• Post-retirement return: Your portfolio should shift to more conservative instruments after retirement. A 7% post-retirement return is realistic with Senior Citizen Savings Scheme, debt funds, and balanced advantage funds.
• Healthcare inflation: Medical costs inflate faster than general inflation — consider allocating an additional 10–15% buffer in your corpus for healthcare.

Who Should Use This Calculator?

This tool is essential for anyone with a regular income who wants to know exactly where they stand on retirement preparedness. It is particularly valuable for salaried employees in their 30s and 40s, self-employed professionals without employer pension coverage, NRIs planning to return to India, and anyone who wants to retire early (FIRE movement).

Key Takeaways

• Start early — the difference between starting SIPs at 25 vs. 35 can halve your required monthly contribution due to the power of compounding.
• Always inflation-adjust your expense assumptions — never plan based on today's costs.
• Maintain a post-retirement conservative portfolio to protect against sequence-of-returns risk.
• Revisit your retirement plan every 2–3 years as income, expenses, and life goals evolve.
