About This Retirement Calculator

This free retirement calculator uses the four-step NISM (National Institute of Securities Markets) framework to answer the two questions every earner eventually faces: how large a corpus will I need on the day I retire, and how much must I save each month to get there? It models both phases of retirement — the accumulation years while you earn and the distribution years while you withdraw — with separate return assumptions for each, plus inflation, your existing savings, and life expectancy.

Retirement planning is more urgent in India than almost anywhere else: there is no universal social security, joint-family support is thinning, and private-sector employees retire with only EPF, which alone rarely sustains three decades of expenses. Meanwhile life expectancy for those who reach 60 keeps rising — planning to 85 or 90 is prudent, not pessimistic. A 30-year-old in Chennai spending ₹50,000 a month today will need roughly ₹2.87 lakh a month at 60 just to maintain the same lifestyle at 6% inflation. Numbers like that feel abstract until you see your own — which is what this calculator is for.

Why You Need a Retirement Calculator

The most expensive retirement mistake is starting late: because of compounding, every five-year delay roughly doubles the monthly saving required for the same corpus. The second is ignoring inflation — savers who target "₹1 crore" as a round number discover it funds barely 8–10 years of expenses at 2046 prices. The third is assuming pre-retirement returns continue after retirement, when the corpus must move to safer, lower-yield assets. This calculator forces all three realities into the arithmetic. For the full methodology, read our NISM retirement corpus guide and the complete investment planning guide.

How to Use This Retirement Calculator

1. Present Age / Retirement Age / Life Expectancy: These define your accumulation years (working) and distribution years (retired). When unsure, use 85–90 for life expectancy — outliving your corpus is the worse error.
2. Current Monthly Expenses: What your household spends today, excluding EMIs that will end and children's costs that won't persist into retirement.
3. Inflation rate: 6% is a reasonable Indian long-term assumption; healthcare inflation runs higher, so lean conservative.
4. Expected returns (pre- and post-retirement): Use 10–12% for the equity-heavy accumulation phase and 7–8% for the debt-heavy distribution phase. Using 12% for both is the most common way people fool themselves.
5. Current savings: Existing corpus (EPF, PPF, mutual funds) earmarked for retirement — its future value reduces the fresh saving required.

The results show your inflation-adjusted expenses at retirement, the required corpus, the future value of what you already have, the shortfall, and the monthly SIP needed to close it. If the SIP figure looks impossible, don't close the tab — test retiring two years later or trimming assumed expenses by 10%; small changes move the answer dramatically.

How to Calculate the Retirement Corpus You Need

Retirement planning requires estimating two things: how much money you will need each month after you stop working, and how large a savings corpus will sustain those withdrawals for your full retirement period. Because inflation erodes purchasing power over time, your current monthly expenses cannot be used directly — they must be projected forward to your retirement date using an estimated annual inflation rate (typically 5–7% for India).

The 25× Annual Expense Rule

The 25× rule (based on the 4% safe withdrawal rate) states that you need a retirement corpus equal to 25 times your annual expenses at retirement. This ensures you can withdraw 4% of your corpus every year without depleting it over a 25–30 year retirement.

Required Corpus = Inflation-Adjusted Annual Expenses × 25

Worked Example

Current monthly expenses: ₹50,000. You plan to retire in 20 years. Assumed inflation: 6% per year.

• Monthly expenses at retirement = ₹50,000 × (1.06)^20 = ₹1,60,357/month
• Annual expenses at retirement = ₹1,60,357 × 12 = ₹19,24,284
• Required corpus = ₹19,24,284 × 25 = ₹4.81 crore
• Monthly SIP needed (at 10% return over 20 years) = ≈ ₹59,000/month

If you already have ₹10 lakh saved and it grows at 10% over 20 years, it becomes ₹67 lakh — reducing the SIP requirement. Use the calculator above to input your exact figures and get a personalised retirement savings plan.

Real-World Retirement Examples

Srinivas, 32, Chennai — starting from EPF alone

Srinivas spends ₹55,000 a month and wants to retire at 60 with cover till 85. With 6% inflation, his expenses at 60 will be about ₹2.8 lakh a month, and the calculator puts his required corpus around the ₹7 crore mark. His ₹8 lakh EPF balance grows meaningfully but covers only a fraction, leaving a monthly SIP requirement of roughly ₹30,000–35,000 at 11% accumulation returns. Sobering — but at 32 it is achievable with step-ups; at 45 it would not be.

Meena, 45, Nagpur — late start, adjusted expectations

Meena starts at 45 with ₹20 lakh saved and ₹40,000 monthly expenses. The calculator shows that retiring at 60 needs a monthly saving beyond her means — but retiring at 63 with a 10% expense trim brings the required SIP within reach. Takeaway: the calculator is most useful for testing trade-offs (retire later, spend less, save more), not for delivering a single verdict.
