Why the 4% FIRE rule fails in India and how you can fix the retirement plan

Creating your early retirement corpus

• The 25X rule for early retirement falls short in India due to higher inflation
• Indian investors should target 35-40X annual expenses for safer retirement
• Indian retirees should use a bucket-based portfolio and dedicated health fund

Early retirement sounds like the ultimate win. No office calls, no salary dependency and complete control over time. Search for how to achieve it, and one rule shows up everywhere: save 25 times your annual expenses and you are financially free.

This idea, the 25x rule or the 4 percent rule for Financial Independence, Retire Early (FIRE), comes from the US but when Indian investors apply the maths, it doesn't work the same way.

Let’s find out why.

How the 25x rule works

The logic is simple. Estimate your annual expenses after retirement and multiply that number by 25.

Lets understand with an example. Take the case of Arun.

Under the 25x rule,  he simply multiplies his expected annual retirement expense of Rs 12 lakh by 25, arriving at a target corpus of Rs 3 crore. This calculation is derived from the 4 percent withdrawal rule, which assumes that withdrawing 4 percent of the corpus annually can sustain retirement spending over time.

Where did the 4% rule come from?

In 1994, US financial planner William Bengen found that if retirees withdrew 4 percent of their retirement corpus every year and increased the withdrawal amount annually to account for inflation, the money could last at least 30 years.

This framework assumes:

- Low inflation

- Stable post-retirement returns

- A 30-year retirement period

And, this is where the maths falters of Indian investors.

Why the 4% rule fails in India?

The 4 percent rule was built using US inflation data, which has historically stayed around 2 to 3 percent. India’s household inflation is structurally higher and often falls in the 5 to 6 percent range. Some lifestyle costs like healthcare and housing rise even faster.

“In India, the FIRE framework that suggests saving 25 times annual expenses often falls short,” said Vinit Rathi, CEO of Avisa Wealth Creators. “The assumption of low inflation does not hold true in India, as lifestyle costs, housing and healthcare expenses typically rise by 6-9 percent annually, eating into retirement corpus faster than investors expect," he said.

Let’s understand by applying Indian assumptions to Arun's example.

In the first year, Arun withdraws Rs 12 lakh, which is 4 percent of a Rs 3 crore corpus. From the second year onwards, the withdrawal amount increases by 6 percent annually to keep pace with household inflation, even though the investment return is assumed to be only marginally higher.

While returns are only marginally higher than inflation, withdrawals keep rising every year. Despite earning 7 percent annually on investments, Arun's corpus slowly erodes. Under these assumptions, the money runs out when Arun is around 79.

That is barely a 29-year retirement window. This is not a failure of discipline. It is a failure of assumptions.

Kirang Gandhi, a Pune-based financial mentor, said, “The 4 percent rule assumes low inflation, social security support and a shorter retirement period. In India, inflation averages around 5-6 percent, healthcare is largely self-funded and people are living longer, which makes a fixed 4 percent withdrawal risky.”

So what should Indian investors do?

Early retirement is not impossible but it needs India-specific calculations.

• Option 1: Treat early retirement as semi-retirement

You can still follow the 4 percent framework but do not rely entirely on the portfolio.

- Continue part-time work

- Build flexible income streams

- Reduce withdrawals in weak market years

Even small annual income can dramatically improve portfolio longevity.

• Option 2: Build a bigger corpus

If you want zero dependence on work income, aim higher. Gandhi said, “Early retirees in India need a much larger safety net. Instead of 25x, target 35x to 40x your annual expenses. This ensures you aren't just surviving but staying ahead of price hikes and are able to maintain your lifestyle post retirement.”

Let’s see how Arun’s corpus will turnout if he considers 35x or 40x as his annual expenses instead of 25x.

If Arun targets a higher safety buffer, his required retirement corpus rises to Rs 4.2 crore at 35 times annual expenses (Rs 12 lakh × 35) and further to Rs 4.8 crore at 40 times annual expenses (Rs 12 lakh × 40), instead of Rs 3 crore under the 25x rule. This higher buffer helps absorb inflation shocks, poor market phases, and rising healthcare costs.

• Use a smarter portfolio structure

Instead of one pooled corpus, experts recommend a bucket-based approach. “A dynamic, bucket-based approach works better in India. Keep two to three years of expenses in liquid assets, maintain a debt bucket for stability, and let equities drive long-term growth," Rathi said.

This structure reduces the need to sell equities during market downturns and stabilises withdrawals.

• Plan separately for healthcare

Healthcare is the biggest blind spot in early retirement planning. Rathi said, "Try to set aside a dedicated Rs 20 to Rs 50 lakh ‘health fund’ on top of your regular insurance.” This fund is meant only for medical shocks in later years.

Bottom line

The 25x rule can serve as a useful starting point but it is not a retirement guarantee. In India, early retirement planning must account for 6 percent inflation rather than 2 percent, a retirement span of 35 to 40 years instead of 30, and real-world expenses that often rise faster than textbook averages.

Financial freedom is not about exiting work early at any cost. It is about making sure you do not outlive your money.
