How to Plan for Retirement in India: Building Your Corpus

Most Indians underestimate how much retirement actually costs, because two forces work quietly against them: inflation and longer lifespans. A retirement corpus is the pool of money you build during your working years to fund the years after. This guide explains how to estimate the number you need, why the old "₹1 crore is enough" assumption is risky, and how to start building toward it.

What is a retirement corpus?

A retirement corpus is the total amount of money you accumulate by the time you retire, invested so it can generate income through your retirement years.

Think of it as replacing your salary. Once you stop working, this corpus, and the income it produces, becomes what you live on. The goal is for it to last as long as you do, without running out.

Why is retirement planning more urgent now?

Three shifts have made retirement planning far more important than it was for previous generations:

• Longer lifespans. Indians are living longer, so financial planners now commonly suggest planning for a retirement that could last 25 to 35 years, often to age 85-90.
• Healthcare inflation. Medical costs in India have been rising considerably faster than general inflation, a pattern widely noted by financial planners, which makes healthcare a major retirement cost.
• Weaker family safety nets. Joint-family support and guaranteed pensions are far less common for private-sector workers, so the responsibility increasingly sits with the individual.

Together, these mean the corpus you need is larger than instinct suggests.

How much corpus do you actually need?

A widely used starting point is the "25x rule": save about 25 times your expected annual expenses at retirement. Indian financial planners commonly adjust this upward, to roughly 28-30x or more, because India's structurally higher inflation erodes purchasing power faster than in the lower-inflation economies where the rule originated. (The RBI's inflation-targeting framework is built around a 4% target within a 2-6% band, well above the 2-3% typical of developed markets.)

As a rough, illustrative example: someone spending ₹50,000 a month today, retiring at 60 and planning to live to 85, could need a corpus in the region of several crore once inflation and moderate post-retirement returns are factored in. The exact number is personal, which is why a calculator matters more than any single rule of thumb.

What is the 4% withdrawal rule?

The 4% rule suggests that if you withdraw about 4% of your corpus in your first year of retirement and adjust for inflation each year after, the corpus should last around 30 years.

In the Indian context, planners often recommend a slightly more conservative 3 to 3.5% withdrawal rate, because higher inflation and the absence of a state pension floor make the standard 4% riskier here. A practical implication: to draw ₹1 lakh a month (₹12 lakh a year), the 25x rule points to roughly ₹3 crore, and the more conservative Indian adjustment points higher. (The 4% rule itself traces back to the US "Trinity Study" of the 1990s, which assumed lower inflation than India's, which is precisely why it is adjusted downward here.)

How inflation and healthcare change the math

Inflation is the silent force that makes retirement expensive. With general inflation historically running well above the levels assumed in Western retirement rules, prices can roughly double over a decade or so, meaning the monthly expense you have today could be several times larger by the time you retire.

Healthcare deserves its own buffer. Because medical costs in India have tended to rise faster than general inflation, many planners suggest keeping a separate medical reserve rather than assuming your main corpus will absorb a major health event. The exact size depends on your city and the kind of care you would want.

How early should you start?

As early as possible, because compounding rewards time more than amount. Starting in your 20s or 30s means a much smaller monthly investment can reach the same corpus, since the money has decades to grow.

The gap is dramatic: someone who begins at 30 typically needs to set aside far less each month than someone who begins at 45 for the same target, simply because compounding does more of the work over a longer runway. We explain this engine in detail in our guide to the power of compounding.

A simple step-by-step approach

1. Estimate your current monthly expenses, honestly and fully.
2. Inflate them to your retirement age using a realistic inflation assumption.
3. Multiply annual retirement expenses by 28-30 to get a target corpus.
4. Add a separate healthcare buffer.
5. Subtract what you already have earmarked (EPF, NPS, existing investments).
6. Work out the monthly investment needed to close the gap.
7. Automate and review every few years as income and goals change.

Common retirement planning mistakes

• Assuming ₹1 crore is enough. For many urban households, it may last only a decade or so against inflation.
• Ignoring healthcare inflation. Planning at general inflation alone understates medical costs badly.
• Starting late. Every delayed year makes the monthly target meaningfully harder.
• Relying only on EPF/NPS. Useful, but often not sufficient on their own.
• Underestimating lifespan. Planning to 75 when you may live to 90 risks outliving the corpus.
