Does the 4% Rule Work in India?

The 4% rule is the most quoted number in retirement planning. Multiply your yearly spending by 25, it says, withdraw 4% of that corpus in the first year, raise the withdrawal with inflation every year after, and the money should last about 30 years. It is simple, it is memorable, and it was built on another country's data. This guide explains where the number comes from, what actually decides whether it holds, and why the answer in India depends more on inflation than on returns.

Where the 4% rule comes from

In 1994 a US financial planner, William Bengen, tested a simple question against historical American stock and bond returns: what is the highest starting withdrawal rate, increased with inflation every year, that would have survived every 30-year period on record? His answer was a little over 4%. A few years later, a study by three professors at Trinity University ran similar tests across different stock and bond mixes and reached broadly the same conclusion for portfolios with a large equity share.

Two details matter. First, the rule is about a withdrawal that grows with inflation, not a flat amount. Second, it was tested on US returns, US inflation and a 30-year horizon. None of those three is automatically true for an Indian retiree.

The number that actually matters: real return

Because the withdrawal rises with prices, what decides how long the money lasts is not the headline return but the return after inflation, the real return. A corpus earning 9% a year while prices rise 6% a year is growing at roughly 2.8% in real terms. A corpus earning 7% with 3% inflation is growing at about 3.9%. The first looks better on paper and is worse for a retiree.

If you assume smooth returns, the arithmetic is precise. Withdrawing 4% a year and raising it with inflation, the corpus lasts roughly:

• 25 years at a 0% real return
• 29 years at a 1% real return
• 35 years at a 2% real return
• 47 years at a 3% real return

So the 4% rule holding for 30 years is roughly the same claim as saying the corpus will earn at least about 1% a year above inflation, on average, without a damaging run of bad years early on. Seen that way, the question for India stops being “is 4% right?” and becomes “what real return is reasonable to assume for my mix of investments?” The withdrawal rate calculator lets you change both numbers and see how the outcome moves.

Why India changes the arithmetic

Indian inflation has generally run higher than American inflation over long periods. The Reserve Bank of India works to a consumer inflation target of 4%, with a tolerance band of 2% to 6%, and the government retained that framework in 2026 for the period to March 2031. A target is a policy objective, not a forecast of what your own household will face. Expenses that matter most in retirement, such as healthcare, have historically risen faster than the general index.

Higher inflation is not a problem in itself if returns are correspondingly higher. The risk is assuming a high nominal return without checking what is left after inflation. Debt instruments, for example, may offer nominal rates that look comfortable but leave a thin real margin once inflation is subtracted, and even less after tax. Equity has historically offered a wider margin over long periods, with much larger swings along the way. Past returns in either asset class are a record, not a forecast.

A second difference is the length of the record. The US data behind the rule stretches back about a century. Reliable Indian equity index history is much shorter, so there are far fewer independent 30-year periods to test against. That does not make the rule wrong for India, but it does mean the evidence is thinner.

Longer retirements need lower rates

The original research looked at 30 years, which suits someone retiring at 60 or 65. Someone stopping work at 45 may need the money to last 45 years or more. Look again at the numbers above: at a 1% real return, 4% runs out in under 30 years. The same return supports a 3.5% withdrawal for about 34 years, and a 3% withdrawal for about 41 years.

That is why people planning long or early retirements often test 3% to 3.5% instead of 4%. The cost is a bigger target: spending of ₹6 lakh a year needs ₹1.5 crore at 4%, about ₹1.71 crore at 3.5%, and ₹2 crore at 3%. There is no free version of safety here, only a trade between the size of the corpus and the margin it leaves you.

What smooth numbers hide: sequence risk

Every figure above assumes the same return every year. Real markets do not cooperate. If a large fall arrives in the first few years of retirement, you are selling units at low prices to fund withdrawals, and those units are not there to recover when markets do. Two retirees with identical 30-year average returns can end up in very different places purely because of the order in which the returns arrived.

This is the single biggest reason a rule of thumb is not a plan. Running a month-by-month SWP simulation with your own corpus and withdrawal, and then repeating it with a weaker return, shows how much room you actually have. Some retirees also keep a few years of spending in lower-volatility assets so that a market fall does not force sales at the worst time, though that has its own cost in lower expected growth.

Tax and costs come out of the same 4%

The rule talks about gross withdrawals. Fund expense ratios, and tax on what you withdraw, both reduce what you can actually spend. Currently, withdrawals from equity mutual funds are taxed only on the capital gain portion, while interest from deposits is taxed in full at slab rate, so the same 4% can leave quite different amounts in hand depending on where the corpus sits. Tax rules change, so confirm the current position before relying on any of this.

So, does the 4% rule work in India?

The honest answer is: it depends on the real return you can reasonably expect, the length of your retirement, and whether a bad start is survivable. As a first estimate of the corpus you need, 25 times annual spending is a useful starting point. As a final number to retire on, it is too blunt. The arithmetic says that if you expect a thin margin over inflation, or a retirement longer than 30 years, a lower withdrawal rate, a larger corpus or flexible spending in bad years each buy you room. Testing those options against your own numbers is more useful than adopting any single percentage.
