What is the 4 percent rule?
The 4 percent rule is a simple way to estimate how much you can withdraw from your retirement savings each year without running out of money too quickly.
It says you withdraw 4 percent of your total savings in the first year of retirement and then increase that amount each year to account for inflation.
The idea is to make your money last for around 30 years. Here is a simple example.
Suppose you retire with a corpus of ₹1 crore. In the first year, you withdraw 4 percent, which is ₹4 lakh.
In the second year, you do not calculate 4 percent of your new corpus. You take the previous year’s ₹4 lakh and increase it for inflation.
This allows your spending to keep pace with rising prices while the rest of your savings remains invested.
The rule was first developed by American financial planner William Bengen in 1994. His research looked at how much retirees could withdraw from their portfolios while still having their money last through a 30-year retirement.
The important question for an Indian retiree is whether the same rule still works when inflation, taxes, investments and retirement income are different.
How does the 4 percent rule actually work?
One part of the rule is often misunderstood. You calculate 4 percent only in the first year. After that, you do not withdraw 4 percent of whatever your portfolio is worth each year.
You start with the first year’s withdrawal and increase that amount for inflation.
Take the example of Ramesh and Sunita, a couple in Pune who retire at 60 with a corpus of ₹2 crore.
Assume inflation is around 5 percent a year.
- Year 1: They withdraw 4 percent of ₹2 crore, which is ₹8 lakh.
- Year 2: They increase the ₹8 lakh withdrawal by 5 percent, taking it to ₹8.4 lakh.
- Year 3: They increase ₹8.4 lakh by another 5 percent, taking the withdrawal to around ₹8.82 lakh.
Their withdrawal therefore rises gradually as the cost of living rises. At the same time, the remaining corpus stays invested and continues to earn returns.
To apply the rule, you can follow four simple steps:
- Add up your retirement corpus across your investments.
- Take 4 percent of that corpus to estimate your first year’s withdrawal.
- Increase that withdrawal each year based on inflation.
- Review the plan regularly as your portfolio, expenses and circumstances change.
The simple formula and how much you actually need?
The calculation also works in reverse. Your first-year retirement income equals your corpus multiplied by 4 percent. If you want to work backwards, divide your desired annual retirement income by 4 percent.
This is the same as multiplying your annual spending by 25. This is commonly known as the 25x rule.
For example, if you want ₹12 lakh a year in retirement, you would need a corpus of roughly ₹3 crore.
If you want ₹6 lakh a year, the calculation points to a corpus of around ₹1.5 crore.
This gives you a quick starting estimate for the corpus you may need to support a particular level of retirement income.
Anuj says, I like the 25x rule because it starts with the life you want to fund, rather than the corpus you happen to have today. Once you know the income you need, you can work backwards and turn that number into a retirement goal. It makes retirement planning much easier to put into perspective.
Why is 4 percent considered a safe rate?
Several factors support the idea behind the rule. Your money remains invested. When you withdraw only a portion of your corpus, the rest remains invested and has the opportunity to generate returns.
The withdrawal also increases with inflation. This helps maintain your spending power as prices rise.
A diversified portfolio can also reduce the impact of any single asset class performing poorly.
A safe withdrawal rate follows the same basic idea. It aims to balance what you need to spend with what your portfolio can potentially support over time.
Does the 4 percent rule work in India?
This is where you need to be careful. The 4 percent rule was developed using American market data, inflation and retirement conditions. Indian retirees face a different set of circumstances.
Three differences are particularly important.
First, inflation.
Bengen’s research was based on an environment where inflation was generally lower than what Indian households have experienced over long periods.
The Reserve Bank of India targets retail inflation at 4 percent, with a tolerance band of 2 to 6 percent. Retail inflation was 3.93 percent in May 2026, according to government data. government data on May 2026 retail inflation
Higher inflation matters because your retirement withdrawal has to increase faster to maintain the same standard of living. That puts greater pressure on your corpus.
Moreover, the RBI’s inflation basket does not reflect the inflation that you may actually experience. This is because your lifestyle expenses have higher inflation than what the RBI accounts for in its calculation.
Second, India does not have a universal government pension.
In the US, Social Security provides many retirees with a regular income floor.
In India, your retirement income may come from several sources, including the Employees’ Provident Fund, National Pension System, pension income, rental income and your investment portfolio.
These sources may cover part of your expenses, but your own retirement corpus may still have to fund a significant portion of your lifestyle.
Third, investment returns can be different.
Indian equity and bond markets have historically offered different return characteristics from their US counterparts. Higher returns can provide some cushion against higher inflation, although this cannot be assumed every year.
So the question is not whether the 4 percent rule is right or wrong for India. The question is whether 4 percent is appropriate for your particular retirement plan.
Factor | Bengen’s world (US) | Indian reality | What does it mean for you? |
Inflation | About 2 to 3 percent | RBI target of 4 percent, with a band up to 6 percent | Withdrawals may need to rise faster |
Government pension | Social Security provides a backstop | No universal pension; EPF and NPS cover only part of retirement needs | Your own savings may need to do more work |
Investment returns | Moderate historical returns | Indian equity and bond returns have historically differed from US markets | Returns can help offset inflation, but are not guaranteed |
Because of these differences, many Indian retirement planners consider a starting withdrawal rate of around 3 to 3.5 percent, more cautious for a long retirement.
This does not mean 4 percent cannot work. It means 4 percent should not automatically be treated as the default rate for every Indian retiree.
Anuj says I usually prefer to test the retirement plan at 3.5 percent first. If the numbers work comfortably, you can then see whether there is room for a higher withdrawal. Retirement planning is not about finding the highest amount you can withdraw. It is about finding an amount you can sustain without putting your future income at risk.
How Indians actually take the money out? : The SWP
In India, one practical way to implement a withdrawal strategy is through a Systematic Withdrawal Plan, or SWP.
An SWP allows you to withdraw a fixed amount from a mutual fund at regular intervals, such as every month or quarter. The remaining investment stays invested.
Suppose your retirement plan says you need ₹8 lakh in your first year. You could divide that amount into monthly withdrawals and set up an SWP to receive the money regularly.
This creates a predictable flow of income while keeping the remaining corpus invested.
There can also be a tax difference between withdrawing from a mutual fund through an SWP and receiving certain other forms of retirement income.
In an SWP, each withdrawal can contain both your original investment and gains. The tax treatment applies to the gain component, subject to the applicable rules for the type of mutual fund and the period for which it has been held.
Your actual tax liability depends on the fund and your circumstances, so the withdrawal strategy needs to be planned rather than treated as a simple 4 percent calculation.

The 4 percent rule for NRIs and GIFT City investors
If you are an NRI planning to retire in India, there is another factor to consider: currency.
Suppose most of your retirement savings are in US dollars or another foreign currency, but your future expenses will be in rupees.
Changes in the exchange rate can affect how much your savings are worth when converted into rupees.
Your corpus may look sufficient in the currency in which you hold it, but its purchasing power in India can change over time. This makes currency planning an important part of retirement planning for NRIs.
Some NRIs also consider GIFT City when planning investments connected to their eventual return to India.
India’s international financial centre provides a framework through which NRIs can access certain financial products and services.
The important point is that the 4 percent calculation should not be done in isolation. Your retirement plan needs to consider where your money is held, which currency you will spend and how your future expenses are likely to change.

Does the 4 percent rule work for early retirement and FIRE?
The FIRE movement, which stands for Financial Independence, Retire Early, has made the 4 percent rule popular among people who want to leave full-time work early. But early retirement creates a major problem.
The original research was based on a 30-year retirement period. If you retire at 50, your money may need to support you for 40 years or more.
That is a very different situation from retiring at 60 and planning for 30 years.
A withdrawal rate that works over 30 years may not provide enough margin over a much longer period.
So, the 4% rule may not work here. The withdrawal percentage needs to be much lower depending upon your actual age of retirement.
The risks and limits of the 4 percent rule
The 4 percent rule is a useful estimate, but it is not a guarantee.
One of the biggest risks is called sequence-of-returns risk.
Simply put, two retirees who have the same portfolio and eventually receive the same average investment return.
One experiences a major market fall during the first few years of retirement. The other experiences the same fall much later.
The first retiree can be in a much worse position because they are withdrawing money while their investments are down. They have fewer assets left to participate when markets recover.
This is why the order in which good and bad returns occur can matter as much as the average return itself. There are other limitations too.
The rule does not automatically account for your tax position. Different retirement income sources can have different tax treatment.
Annuity income, for example, is taxed differently from gains generated through mutual fund investments.
The rule also assumes a relatively consistent spending pattern. Real retirement spending does not work that way.
You may spend less during some years and much more when you face a major medical expense, home repair or other one-off cost.
Healthcare is particularly important because medical costs can rise much faster than general inflation.
Research on medical inflation in India has estimated medical inflation at around 12 to 13 percent a year, significantly above general inflation.
A 4 percent withdrawal calculation does not automatically create a separate provision for these expenses.
The rule can also fail in two opposite directions.
You could withdraw too little and spend years being unnecessarily cautious with money you had saved for your retirement.
It could also be that you withdraw too much and eventually face a shortfall.
Neither outcome means the formula itself is not useful. It means retirement planning is dynamic, and cannot be reduced to one rule.
Should you follow the 4 percent rule?
The honest answer is that 4 percent is a useful starting benchmark, not an autopilot setting for the next 30 years.
Before using it, ask yourself a few questions:
- Is 4 percent of your expected corpus enough to cover your actual expenses?
- How much will EPF, NPS, pension and rental income contribute?
- How long does your corpus need to last?
- What happens if you live longer than expected?
- Could you reduce your spending during a prolonged market downturn?
- Do you have enough money set aside for large medical or other one-off expenses?
- Are you comfortable reviewing your withdrawal strategy every year?
Your answers can tell you whether 4 percent is reasonable or whether a lower withdrawal rate would provide more room for uncertainty.
The right withdrawal rate should reflect your retirement age, spending needs, other income, investments and ability to adjust your lifestyle.
Alternatives and adjustments to the 4 percent rule
You do not have to follow the 4 percent rule exactly. Several approaches can either replace it or work alongside it.
Strategy | How does it work? | Best suited to |
Lower fixed rate | Start at 3 to 3.5 percent instead of 4 percent | Long or early retirements and cautious retirees |
Guardrails | Adjust withdrawals when markets or portfolio values change | If you can reduce spending in difficult years |
Bucket strategy | Divide savings into short, medium and long-term buckets | If you want a planned cash flow while keeping long-term investments intact |
SWP with annual review | Set a withdrawal amount and review it each year | Retirees using mutual funds for regular income |
Annuity floor plus upside | Use guaranteed income for essential expenses and apply a withdrawal strategy to the remaining corpus | If you want a guaranteed base income |
There is no requirement to choose just one strategy. A retirement plan can combine several of them.
For example, essential expenses could be covered through pension or annuity income, while discretionary expenses come from an investment portfolio.
An SWP can then be used to provide regular cash flow, with the withdrawal amount reviewed periodically.
The objective is to create enough flexibility to deal with market movements and changes in your expenses.

Conclusion
The 4 percent rule has earned its place in retirement planning because it provides a simple way to think about sustainable withdrawals. But it was developed using US market data and a US retirement environment.
Indian retirees face different inflation, taxation, investment and retirement-income conditions. That does not make the rule irrelevant. It means you need to adapt to it.
For a long retirement, starting with a lower withdrawal rate such as 3 to 3.5 percent can provide more room for uncertainty.
For early retirement, the need for caution becomes even greater because the corpus may have to support you for several additional decades.
Your retirement plan should ultimately answer a more important question: how much can you spend while still being comfortable that your money can support the life you want for as long as you need it?
FAQs
How much do I need to retire in India using the 4 percent rule?
Multiply the annual income you want by 25. If you want ₹1 lakh a month, or ₹12 lakh a year, the calculation gives around ₹3 crore. These are starting estimates.
Your actual requirement will depend on inflation, retirement age, expenses, other income and how long your money needs to last.
Is the 4 percent rule safe given India’s higher inflation?
It can provide a useful starting point, but it should not automatically be treated as safe for every Indian retirement. Higher inflation can increase your withdrawals faster and put more pressure on your corpus.
For this reason, some retirement plans may start with a withdrawal rate closer to 3 to 3.5 percent and test whether the numbers still support the desired lifestyle.
Does the 4 percent rule work for early retirement or FIRE?
It needs adjustment. The original rule was tested over 30-year periods. Someone retiring at 45 or 50 could need their money to last much longer.
A lower withdrawal rate and a larger retirement corpus can provide a wider margin for a longer retirement.
Can NRIs use the 4 percent rule to plan retirement in India?
Yes, but currency needs to be considered. If your savings are held in dollars or another foreign currency while your retirement expenses will be in rupees, exchange-rate movements can affect your purchasing power.
Your retirement plan should account for both the currency of your investments and the currency of your future expenses.
How is the 4 percent rule different from an SWP, and can I combine them?
The 4 percent rule is a way to estimate how much you can withdraw. An SWP is a facility that allows you to receive regular withdrawals from a mutual fund.
The two can work together. You can use a withdrawal-rate calculation to determine your annual requirement and then use an SWP to distribute the money regularly.
What is a safer alternative to the 4 percent withdrawal rule?
There are several options. You could start with a lower fixed rate of 3 to 3.5 percent, use a guardrails approach that adjusts spending based on portfolio performance, use a bucket strategy, or cover essential expenses through an annuity or pension.
The appropriate approach depends on your income needs and how flexible your spending can be.
How often should I review my withdrawal rate during retirement?
At least once a year is a sensible starting point. An annual review allows you to account for changes in your portfolio, inflation, spending and other income.
It also gives you an opportunity to adjust the withdrawal amount if your circumstances change.
