Safe withdrawal rate: How to use it to plan your retirement income

What the safe withdrawal rate means in retirement planning

The safe withdrawal rate (SWR) is the percentage of your savings you can withdraw each year while keeping your money lasting throughout retirement. It’s a guide that balances two goals that often pull in opposite directions: maintaining your lifestyle and protecting your savings from running out too soon.

The idea became popular after research in the United States showed that withdrawing about 4% of a balanced investment portfolio each year, adjusted for inflation, could have sustained a 30-year retirement in past market conditions. This finding became known as the ‘4% rule’ and remains a common reference point for millions of people planning life after work, though it doesn’t account for fees, taxes or future market changes.

Still, no single rate fits everyone. Your personal withdrawal rate depends on several factors:

• Retirement length. How many years you expect your savings to last.
• Portfolio structure. The balance between growth assets and stable income sources.
• Inflation. How rising prices will affect future costs and purchasing power.

For some, 4% might be reasonable; for others, a rate closer to 3% or 5% could make more sense. What matters is understanding that your rate should reflect your own financial plan, not a one-size-fits-all rule.

How to calculate your safe withdrawal rate (+ example)

A safe withdrawal rate gives structure to your retirement plan. It shows how much income your savings can support each year and how much you need to save to reach that goal. The process follows three clear steps:

Calculate your withdrawal rate from your current savings

Divide your planned annual withdrawal by your total savings.

For example, if you’ve saved EUR 800,000 and plan to withdraw EUR 32,000 per year, the calculation is EUR 32,000 ÷ EUR 800,000 = 0.04, or 4%.

Reducing the rate to 3% would result in an annual withdrawal of EUR 24,000, while raising it to 5% would increase it to EUR 40,000, but with a greater risk of depleting your funds sooner.

Set your savings goal for a chosen rate

Reverse the formula to see how much you need to save for your target income. To find the desired amount, divide your desired annual income by your chosen withdrawal rate.

For example, to withdraw EUR 40,000 per year at a 4% rate, the calculation is EUR 40,000 ÷ 0.04 = EUR 1,000,000.

This gives a clear savings target based on the lifestyle you aim to maintain.

Adjust for inflation each year

Inflation reduces what your withdrawals can buy over time. To maintain your purchasing power, increase your withdrawals roughly in line with inflation, but stay flexible —you might hold them steady after years when markets have fallen.

If inflation averages 2.5%, a EUR 40,000 withdrawal in the first year would become EUR 41,000 in the second year.

The goal is to preserve your lifestyle, not to expand it. In years when markets perform poorly, keeping withdrawals flat can help you extend the life of your portfolio.

If you follow these steps, you can build a reasonable starting estimate for your retirement.

Note: Examples exclude fees and taxes. Both reduce sustainable withdrawal amounts.

Safe withdrawal rate examples by age

A safe withdrawal rate isn’t fixed. The examples below show typical ranges based on balanced portfolios (for example, 50–60% global equities and 40–50% high-quality bonds) and moderate inflation assumptions:

• Age 55: 3.0–3.5%. Retiring early means your savings must last longer, often 35 years or more. A cautious approach is essential in this case. At this level, a portfolio of EUR 1 million could provide about EUR 30,000 to EUR 35,000 per year, adjusted for inflation. This slower pace gives your investments more time to recover from market drops.
• Age 65: 3.8–4.2%. A 30-year retirement horizon suits the traditional 4% guideline. At 4%, a EUR 1 million portfolio would yield approximately EUR 40,000 annually, adjusted for inflation. Many retirees use this as a baseline, modifying it over time based on portfolio performance and spending flexibility.
• Age 75: 4.5–5.0%. A shorter horizon allows slightly higher withdrawals, though risk tolerance and health still matter. At 4.8%, the same EUR 1 million portfolio could support roughly EUR 48,000 per year. This assumes a continued mix of growth and income assets appropriate for your risk tolerance.

You can also test these numbers in a safe withdrawal rate calculator to see how long your savings might last under different market conditions.

Limitations of the safe withdrawal rate method

A safe withdrawal rate helps retirees manage uncertainty, but no formula can guarantee a perfect outcome.

Below are the main limits that can influence how well this method works:

Market returns are unpredictable

The 4% rule assumes steady long-term averages, but markets are rarely predictable. Returns arrive unevenly. This ‘sequence-of-returns risk’ means substantial early gains can stretch your portfolio, while poor early results can shorten its life even if the total average looks fine.

Inflation doesn’t stay constant

Rising prices reduce what each withdrawal can buy. Most models assume inflation of around 2–3%, but prolonged periods of higher inflation can erode purchasing power more quickly than expected and put pressure on your spending plan.

Personal circumstances change

Health issues, family support, or home repairs can alter expenses without warning. A static plan can’t adapt to these changes, so it helps to be flexible rather than sticking to a single number.

Interest rates and yields affect returns

Lower bond yields reduce the income that used to stabilise portfolios. When safe assets earn less, maintaining a 4% withdrawal rate may require a higher share of equities or lower spending expectations.

Modern alternatives to the safe withdrawal rate method

Retirement planning today allows for more flexibility. These newer approaches aim to adapt withdrawals to market conditions, personal needs, and income sources, rather than following a single percentage every year.

Here are the most common approaches worth considering:

Dynamic withdrawal strategies

These adjust spending based on portfolio performance. In good years, withdrawals may rise slightly; in weaker years, they pause or reduce. The goal is to extend your portfolio life without significant lifestyle cuts.

Percentage-based withdrawals

Instead of taking the same euro-denominated amount each year, some retirees withdraw a fixed percentage of their portfolio’s current value. In this way, your income can fluctuate, but this helps limit withdrawals when markets fall and can reduce the risk of eroding the principal.

Hybrid or flexible approaches

Some retirees mix elements of different withdrawal strategies. For example, they might set a base income using a fixed euro amount for essentials and then add a percentage-based top-up tied to portfolio performance. In strong years, they withdraw a bit more; in weak years, they scale back. This creates a middle ground between predictability and adaptability.

Practical retirement planning tips that keep withdrawals safe

Having a safe withdrawal rate is one thing. Keeping it safe over time is another. These steps may help support your plan when markets change:

Review your plan once a year

Check your spending, savings balance, and market conditions annually. If your portfolio has fallen sharply or inflation has risen faster than expected, pause any withdrawal increase or reduce spending slightly until conditions stabilise.

Combine withdrawals with guaranteed income

Use pensions, annuities, or state benefits to cover the essentials: housing, food, and healthcare. Then let your portfolio handle extras, such as travel or hobbies. This mix can provide more security and reduces the pressure to withdraw too much in bad years.

Set money aside for large or unpredictable costs

Health expenses, home repairs, or family support can quickly upset a plan. Keep a separate emergency fund for those moments so your long-term portfolio stays intact.

Avoid impulsive decisions

It’s tempting to change course when markets fall, but reacting too quickly often causes more harm than good. A plan that works is one you can stick to, especially when it feels hardest.

Conclusion: A rate you can live with

No one reaches retirement feeling fully ready. There’s always a mix of relief and doubt about money, health, or life after work in general. A safe withdrawal rate helps bring a little order to that uncertainty. It doesn’t promise anything, but it can give you a way to plan without too much worry.

What matters most is finding a rhythm that feels sustainable; withdraw enough to live comfortably, but not so much that wondering if you can afford tomorrow keeps you awake at night. Over time, the right rate isn’t the one that looks perfect on paper but the one that lets you enjoy the years you’ve worked and planned so hard for.
