Retirement Corpus in India: How to Use the 30X Rule With Inflation

Many people say, “I will retire when I have ₹5 crore.” But no single number works for everyone. Your corpus depends on your expenses, your age, and inflation. This guide shows you how to find your own number, step by step. We use the 30X rule, which is a simple planning guide. We also show the SIP you may need to reach the goal. You do not need to be a finance expert to follow it. By the end, you will have a clear first number. All people in the examples are hypothetical. Returns are not guaranteed.

How Does the Corpus Change With the Multiple and Inflation?

Small changes in your assumptions move the number a lot. The table below uses one hypothetical case. A 40-year-old spends ₹1.2 lakh a month today and retires in 15 years.

What Is the 30X Rule for Retirement?

The 30X rule is simple. Multiply your yearly expenses by 30. The answer is your target corpus.

Here is why it works. One divided by 30 is 3.33%. So you withdraw 3.33% of the corpus in the first year. After that, you raise the amount each year to match inflation.

Other countries use the 4% rule, which equals a 25X corpus. It came from US research in the 1990s. That research studied a 30-year retirement and a mix of US shares and bonds. Later studies disagree on the exact safe rate. So treat any single rate as a guide.

India has higher inflation. Retirement can also last 30 to 35 years. So 30X is a more careful starting point for Indian families. But it is only a simple guide. It does not guarantee that your money will last.

How Does Inflation Change Your Retirement Number?

Meet Vignesh, a hypothetical 40-year-old. He wants to retire at 55, which is 15 years away. His monthly expense today is ₹1.2 lakh. This does not include his home loan EMI (a fixed monthly loan payment).

First, find the number in today’s prices. ₹1.2 lakh × 12 months is ₹14.4 lakh a year. Multiply by 30, and you get ₹4.32 crore. But this is today’s price.

Now add inflation. At 6% a year, prices rise about 2.4 times in 15 years. So his yearly expense becomes about ₹34.5 lakh. That is about ₹2.88 lakh a month. At 30X, his corpus is about ₹10.35 crore. In today’s money, that equals only about ₹4.3 crore.

Is 6% a fair number? RBI targets 4% retail inflation, with a comfort band of 2% to 6%. Retail inflation rose to 5.54% in September 2026, as per media reports of MoSPI data. So 6% is a careful planning number.

Do Medical Costs Rise Faster Than Other Costs?

Usually, yes. Aon is a global advisory firm. Aon projects India’s employer medical plan cost trend at 10.1% for 2027. That is down from 11.5% for 2026. Aon’s general inflation figure for India is about 4% in both years.

These are group health plan figures, not your own premium. Another survey, by Mercer Marsh Benefits, put India’s 2026 trend at 9.9%. The numbers differ, but all are well above general inflation. So plan your health insurance separately. Review it every year.

Will Your Expenses Fall After Retirement?

Some will. Your home loan EMI, children’s education, and office travel usually end. But medical care, leisure travel, and home repairs often rise.

So list only the costs that will continue after retirement. Then add a buffer of 10% to 15%. This buffer is a planning habit, not a rule.

Vignesh vs Divya: Same Corpus, Very Different SIP

Now meet Divya, a hypothetical 25-year-old. She also wants to retire at 55, which is 30 years away. Her monthly expense today is ₹50,000. She has no savings yet.

Both need about ₹10.35 crore. But in today’s money, Vignesh needs ₹4.3 crore and Divya needs only ₹1.8 crore. Vignesh’s first SIP is also about eight times Divya’s at 12% returns. Time does most of the work.

These SIP figures assume that Vignesh’s ₹35 lakh grows at the same return rate. They also assume the SIP starts at the beginning of each month. The SIP rises 10% each year. This is called a step-up SIP. You raise your SIP when your salary rises.

Is 12% guaranteed? No. No return is guaranteed. That is why we show 10% as well. Always check both cases.

How Long Will the Corpus Last?

Take Vignesh’s ₹10.35 crore. Assume he withdraws 3.33% in year one. He raises the withdrawal 6% every year. The corpus earns 7% a year. Under these assumptions, the money lasts about 36 years. That takes him from age 55 to about age 90. This is an assumption, not a promise. So review it every year.

What Four Levers Can Reduce a Big SIP?

A first SIP of ₹1.02 lakh feels heavy for Vignesh. He has four levers. The first is his retirement age. The second is his monthly expense. The third is the yearly SIP step-up. The fourth is his home loan EMI.

Retiring later raises the corpus, because inflation runs longer. But the SIP still falls, because it runs for more years.

Now the EMI. Vignesh pays ₹25,000 a month. Ideally, the loan ends before he retires. If it ends five years early, he can move that ₹25,000 into a SIP for the last five years. At 12%, that grows to about ₹20 lakh.

But what if the loan still runs at retirement? Suppose an 8.75% loan has five years left. The balance is about ₹12 lakh. He needs a separate plan to repay it. We left EMI out of the corpus, because it should not be part of retirement spending.

Delay also costs a lot. Divya’s first SIP is about ₹12,900 if she starts at 25. If she starts at 35, it is about ₹55,500. That is 4.3 times higher. At 45, it is about ₹3.16 lakh, which is another 5.7 times higher.

How Do EPF, NPS and Pension Fit In?

You can subtract expected money from EPF (Employees’ Provident Fund), NPS, and pensions from your target. But a flat pension loses buying power every year because of inflation.

NPS is the National Pension System. Its regulator, PFRDA, changed the exit rules in December 2025. A non-government subscriber with a corpus above ₹12 lakh can now take up to 80% as a lump sum. At least 20% must buy an annuity, which is a regular pension from an insurer. Government employees still have a 60% lump sum limit.

Tax is the catch. In the latest sources we checked (mid-2026), income tax law still exempts only 60% of the NPS corpus. So the extra 20% may be taxable at your slab rate. Annuity income is also taxable every year. Please verify this information from the latest official source before you choose your exit.

What Are Three Common Retirement Myths?

• Myth: ₹10 crore is enough for everyone. Fact: It depends on your expenses. After 15 years at 6% inflation, a ₹50,000 monthly expense needs about ₹4.3 crore. A ₹1.5 lakh expense needs about ₹12.9 crore.
• Myth: Today’s expense × 30 gives my corpus. Fact: That is today’s price. Inflation can more than double it.
• Myth: I have PF, NPS, and a pension, so I need no corpus. Fact: You can subtract them from your target. But a flat pension loses value each year, and annuity income is taxable.

What Five Steps Can You Take This Week?

1. Write down the monthly expense that will continue after retirement. Leave out EMI and children’s education.
2. Choose your retirement age. Count the years left.
3. Use this formula: monthly expense × 12 × inflation factor × 30. The inflation factor is (1 + inflation) raised to the number of years. At 6% for 15 years, it is about 2.4.
4. Subtract your savings, EPF, and NPS. Then work out the SIP at both 10% and 12% returns.
5. Raise your SIP 10% every year. Plan to end your home loan early. Buy health insurance separately.

If a big SIP feels impossible, start with what you can. For example, begin with ₹10,000 and raise it 10% each year. Do not stop your SIP when markets fall. You can also retire two to three years later.

Frequently Asked Questions About the 30X Retirement Rule

What is the 30X rule for retirement?

The 30X rule says your retirement corpus should be 30 times your yearly expenses. One divided by 30 is 3.33%, so you withdraw about 3.33% of the corpus in the first year. After that, you raise the withdrawal each year for inflation. It is a simple planning guide. It does not guarantee that your money will last.

How much retirement corpus do I need in India?

It depends on your expenses, your age, and inflation. As an illustration, a monthly expense of ₹1.2 lakh today becomes about ₹2.88 lakh in 15 years at 6% inflation. At 30X, that needs about ₹10.35 crore. A monthly expense of ₹50,000 needs about ₹4.3 crore over the same period. Use your own numbers, not someone else’s.

How is the 30X rule different from the 4% rule?

The 4% rule is the same as a 25X corpus. It comes from US research on a 30-year retirement. The 30X rule starts at 3.33%, which is more careful. India has higher inflation, and retirement can last 30 to 35 years. So 30X is a more careful starting point for Indian families. Neither rule is a guarantee.

What inflation rate should I use for retirement planning?

Use a careful number, and test more than one. RBI targets 4% retail inflation, with a comfort band of 2% to 6%. This guide uses 6%, the top of that band. Show 5%, 6%, and 7% side by side, as the table above does. Medical costs usually rise faster, so plan health insurance separately.

How much SIP do I need for a ₹10 crore retirement corpus?

It depends on your age and savings. In our example, a 25-year-old with no savings needs a first-month SIP of about ₹12,900. A 40-year-old with ₹35 lakh saved needs about ₹1.02 lakh. Both assume 12% returns and a 10% yearly SIP increase. At 10% returns, the figures rise to about ₹17,200 and ₹1.23 lakh. Returns are not guaranteed.

Did the NPS exit rules change in 2025?

Yes. PFRDA changed the rules in December 2025. A non-government subscriber with a corpus above ₹12 lakh can take up to 80% as a lump sum. At least 20% must buy an annuity, which is a regular pension from an insurer. Income tax law still exempts only 60%, so the extra 20% may be taxable. Please verify this information from the latest official source.

Is a 12% return guaranteed on a SIP?

No. No investment return is guaranteed. Mutual fund returns change with the market. We show 10% and 12% only to illustrate how the SIP amount changes. Always plan with more than one return scenario. Please read all scheme related documents carefully before you invest.
