The 4% Rule - Does It Really Work in Poland?

The 4% Rule -- Does It Really Work in Poland?

The 4% rule is the cornerstone of the FIRE (Financial Independence, Retire Early) movement. It says you can safely withdraw 4% of your investment portfolio each year and your capital should last at least 30 years. But the rule was developed in the United States, based on US capital markets. Does it hold up in Polish conditions?

Where Does the 4% Rule Come From?

The 4% rule originates from William Bengen's 1994 study (later confirmed by the Trinity Study). Bengen analysed historical returns from US stocks and bonds going back to 1926 and found that a 50/50 (stocks/bonds) portfolio would have survived every 30-year period with annual withdrawals of 4% (adjusted for inflation).

Key assumptions:

• Portfolio: 50-75% US stocks, remainder US bonds
• Time horizon: 30 years
• First withdrawal: 4% of the initial portfolio value
• Subsequent withdrawals: adjusted for CPI inflation

Why Poland Is Different

1. Inflation

Poland has historically higher and more volatile inflation than the US. Between 2021 and 2023, inflation exceeded 10%. Inflation-adjusted withdrawals drain a portfolio faster.

2. Currency

The PLN is an emerging-market currency, subject to wider swings. If you invest in global ETFs denominated in USD or EUR, exchange-rate movements can work for or against you.

3. Taxes

The US offers favourable long-term capital-gains rates (0-15-20%). Poland has a flat 19% Belka tax. This reduces the effective rate of return.

4. Capital Markets

The GPW (Warsaw Stock Exchange) has historically delivered lower returns than the S&P 500. The WIG20 barely grew over the past 15 years. That is why most Polish FIRE investors invest globally.

Is 4% Safe for a Polish Investor?

Scenario: Global Portfolio in PLN

If you invest in a global ETF (e.g. VWCE), your returns approximate the global equity market. The historical real return on global stocks is about 5-7% per year.

After accounting for:

• 19% Belka tax
• Higher PLN inflation (averaging 3-4% long-term)
• ETF costs (0.2-0.3%)

A safe withdrawal rate for Poland is closer to 3-3.5%, not 4%.

Why 3.5%?

At 3.5% you have a much larger margin of safety.

Practical Adjustments for Poland

1. Use 3.5% Instead of 4%

With expenses of 5,000 PLN/month (60,000 PLN/year):

• 4% rule: 1,500,000 PLN
• 3.5% rule: 1,714,000 PLN

The 214,000 PLN difference is the price of peace of mind.

2. Flexible Withdrawal Rate

Instead of rigidly withdrawing a fixed amount, adjust to market conditions:

• Market rising: withdraw 4%
• Market falling: cut back to 3% and reduce spending
• Market crash: withdraw the minimum and pick up some freelance income

3. Cash Buffer

Keep 1-2 years of living expenses in cash or short-term bonds. When markets drop, live off the buffer instead of selling equities at depressed prices.

4. Partial Income

You do not have to be 100% retired. Even modest earnings from occasional work (2,000 PLN/month) dramatically lower the required capital:

• Need: 60,000 PLN/year
• Work income: 24,000 PLN/year
• From portfolio: 36,000 PLN/year
• Required capital (3.5%): 1,028,000 PLN instead of 1,714,000 PLN

Sequence-of-Returns Risk -- The Biggest Threat

The most dangerous risk is the sequence of returns. If the first years after you stop working bring deep market losses, the portfolio may not survive 30 years -- even if the average return would have been sufficient.

Example:

• Portfolio: 1,500,000 PLN, withdrawals of 60,000 PLN/year
• Scenario A: first 3 years +10%, then -20% -- portfolio survives
• Scenario B: first 3 years -20%, then +10% -- portfolio may not survive

Solutions:

• Cash buffer (see above)
• Flexible withdrawals
• Starting with a lower withdrawal rate

How to Monitor Your Runway

The 4% (or 3.5%) rule is a simplification. In practice, your situation changes every month -- the portfolio rises or falls, expenses shift, new income sources appear.

Freenance dynamically calculates your Financial Freedom Runway -- how many months you could live without working, based on current data. That is more practical than a static rule because it reflects your real situation.

Alternatives to the 4% Rule

Guyton-Klinger Rule

Flexible withdrawals with "guardrails" -- you increase withdrawals in good years and cut back in bad ones. Allows a higher initial rate (4.5-5%).

Bucket Strategy

Divide the portfolio into three "buckets":

1. Short-term (1-3 years): cash, short-term bonds
2. Medium-term (3-7 years): bonds, income ETFs
3. Long-term (7+ years): equities, growth ETFs

You live off bucket 1, replenishing it from bucket 2, which in turn is topped up from bucket 3.

Live Off Dividends

Instead of selling assets, live on the dividends they pay. Capital remains untouched. Requires a larger portfolio (dividend yield of 3-4% vs the 4% rule).

Summary

The 4% rule is a useful starting point, but under Polish conditions it is wiser to apply a 3-3.5% rule and supplement it with flexible withdrawals, a cash buffer, and possible part-time income. The key is not to rigidly follow a single rule, but to actively monitor your financial situation and adapt your strategy to reality.
