How to take money from your retirement corpus without running out

Most people focus heavily on returns before retirement. Once retirement starts, withdrawals matter far more.

• Retirement withdrawal rate varies by lifespan, investments, and flexibility.
• The 4% rule may be too optimistic for long retirements.
• A 3-3.5% withdrawal rate is safer and more sustainable for retirees.

One of the hardest questions in retirement planning is also the most practical one: how much money can you safely take out every year without running out?

There is no single number that works for everyone. The “right” withdrawal rate depends on how long your retirement might last, how your money is invested, how your expenses change over time, and how much flexibility you have if things don’t go to plan. But there are some useful ways to think about it.

Why this question matters more than returns

Most people focus heavily on returns before retirement. Once retirement starts, withdrawals matter far more.

Even a well-sized corpus can fail if withdrawals are too aggressive in the early years. This is because of something called sequence risk: if markets fall early in retirement while you are also withdrawing money, the damage compounds. You are selling assets when prices are low, leaving less money to recover later.

That’s why a “safe” withdrawal rate is really about protecting against bad timing, not just average returns.

The popular 4 percent rule, and its limits

You may have heard of the 4 percent rule. It suggests that you can withdraw 4 percent of your retirement corpus in the first year, adjust that amount for inflation every year after, and expect the money to last around 30 years.

It’s a useful starting point, but it has limitations.

First, it was developed using US market data and assumes a specific mix of equity and debt. Second, it was designed for a 30-year retirement, not for someone retiring early or expecting to live into their 90s. Third, it assumes you stick rigidly to the rule even during bad years, which is rarely how real people behave.

For many retirees, especially outside the US or those retiring early, 4 percent may be optimistic.

A more conservative starting range

For long retirements, many planners prefer starting closer to 3 to 3.5 percent. That may feel low, but it builds in a margin of safety.

For example, on a Rs 2 crore corpus, a 3.5 percent withdrawal means Rs 7 lakh a year, or about Rs 58,000 a month, before tax. That amount then rises gradually with inflation, assuming the portfolio supports it.

This approach gives your investments more room to grow and recover from market downturns.

Your asset mix changes the answer

Withdrawal rates are not independent of how your money is invested.

If most of your corpus sits in fixed deposits or low-yield debt, your sustainable withdrawal rate is lower because returns barely beat inflation. If your portfolio includes a reasonable equity allocation, the money has a better chance of growing over time, supporting higher long-term withdrawals.

That said, higher equity exposure also means higher short-term volatility. The solution is not avoiding equity entirely, but structuring withdrawals so you are not forced to sell equity during market crashes.

Many retirees use a bucket approach: short-term expenses in cash and debt, and long-term money in equity.

Spending does not stay flat in real life

One assumption that rarely holds is that expenses rise steadily with inflation forever.

In reality, spending often follows a curve. Early retirement can be expensive, with travel and lifestyle spending. Mid-retirement may be calmer. Later years may see healthcare costs rise, but discretionary spending often falls.

A rigid inflation-linked withdrawal every year may not match how you actually live. Being willing to spend a little less in bad market years and a little more in good ones greatly improves sustainability.

Flexibility is one of the most underrated retirement assets.

Taxes and healthcare matter more than people expect

Withdrawals are not just about headline numbers. Taxes can materially reduce what you actually receive, especially if most income comes from interest or taxable withdrawals.

Healthcare costs are another wildcard. Even with insurance, out-of-pocket expenses tend to rise with age. A safe withdrawal plan always assumes higher medical spending later, not just average inflation.

So how do you decide what’s safe?

A practical way to approach this is: Start conservatively in the first few years, especially if markets are expensive or volatile. Keep at least two to three years of expenses in safer assets so you are not forced to sell equity in a downturn. Review withdrawals annually instead of locking yourself into a fixed rule. And be honest about how flexible your spending really is.

There is no perfect withdrawal rate. But a cautious start, combined with sensible investing and periodic adjustment, does far more to protect your retirement than chasing an extra half-percent of income in the early years.

In retirement, longevity is the goal. The money just needs to last as long as you do.
