How Inflation Eats Your Savings

Quick Answer

At 4.5% inflation, your 100,000 PLN loses ~4,500 PLN in purchasing power per year. A 5.5% deposit looks good, but after subtracting inflation (4.5%) and the Belka tax (19% on gains), your real return is just ~0.15% — essentially zero. To truly beat inflation, you need EDO Treasury bonds, ETFs, or gold.

How Much Are You Really Losing to Inflation?

Calculator: 100,000 PLN at Different Inflation Levels

At 4.5% inflation, your 100,000 PLN loses nearly 20,000 PLN in real value over 5 years. At the 2023 peak (18%) — over 56,000 PLN.

Deposits vs Inflation — The Brutal Truth

The best deposits in March 2026 offer ~5.5%. Sounds good? Let's do the math:

5.5% Deposit at 4.5% Inflation

*Inflation calculated on the total amount including interest.

Conclusion: A 5.5% deposit at 4.5% inflation yields a real gain of ~0.15% — practically zero. Your money grows nominally, but purchasing power stands still.

When Inflation Exceeds the Deposit Rate

In 2022, when Polish inflation hit 17% and deposits yielded 5–7%, savers lost 10–12% per year in real terms. That's like burning every tenth zloty.

How to Beat Inflation: 5 Strategies

1. EDO Treasury Bonds (4-Year, Inflation-Indexed)

The best instrument for a Polish saver who wants to protect against inflation:

• Mechanism: 1.00% margin + CPI inflation
• At 4.5% inflation: return = 5.50% (real ~1.00%)
• Belka tax: 19%, but applied to the full nominal gain
• Real return after tax: ~0.50–0.80% above inflation
• Minimum investment: 100 PLN, no maximum
• Liquidity: redeemable after 1 year (with loss of last period's interest)

Comparison: 5.5% deposit vs EDO at different inflation levels:

EDO wins when inflation exceeds ~4% — and decisively so. The higher inflation goes, the more EDO protects your money.

2. COI Bonds (3-Year, Inflation-Indexed)

• Mechanism: 0.50% margin + CPI inflation
• Lower margin than EDO, but shorter lock-up period
• Good option if you don't want to tie up money for 4 years

3. Broad-Market ETFs

Historically, stock markets deliver 7–10% annual returns over the long term — beating inflation. Examples:

Note: ETFs carry risk — they can drop 20–40% in the short term. This is an option for a minimum 5–10 year horizon.

4. Gold

Gold is the classic inflation hedge:

• From 2020–2025, gold gained ~80% (from ~$1,500 to ~$2,700 per ounce)
• During inflationary peaks, it historically gains 10–25% annually
• Generates no interest or dividends — returns come only from appreciation
• Available via: gold coins (e.g., Krugerrand), gold ETFs, physical gold from mints

Optimal allocation: 5–15% of your portfolio in gold as an inflation hedge.

5. Real Estate (Rental Income)

Rents tend to rise roughly with inflation (historically 3–5% annually in Poland). But:

• Requires substantial starting capital (200,000+ PLN for a down payment)
• Maintenance costs, taxes, vacancy risk
• Rental yield in Warsaw: ~4–5% gross (before costs)
• Better as a portfolio complement, not a sole strategy

What to Do with Your Money

Sample Plan for 100,000 PLN

1. Emergency fund (6 months of expenses): in a savings account — accept the inflation loss for liquidity
2. EDO bonds (30–40%): 30,000–40,000 PLN — inflation protection
3. Broad-market ETF (30–40%): 30,000–40,000 PLN — real growth, 5+ year horizon
4. Gold (5–10%): 5,000–10,000 PLN — hedging
5. Cash/short deposits (10–15%): for investment opportunities

This allocation is not investment advice — it's an illustration of the diversification principle.

FAQ

How much do I lose to inflation by keeping money in an account?

At 4.5% inflation and 1% account interest, you lose ~3.5% per year in real terms. On 100,000 PLN, that's ~3,500 PLN in purchasing power annually. After 10 years, your 100,000 PLN is worth ~70,000 PLN in real terms.

Do deposits protect against inflation?

Only partially. Under current conditions (5.5% deposit, 4.5% inflation), the real return after Belka tax is ~0.15%. Deposits prevent nominal loss but don't build real wealth.

What is the Belka tax and how does it affect savings?

The Belka tax is a 19% tax on capital gains (interest, dividends, investment returns). On a 5.5% deposit of 100,000 PLN, the bank withholds 1,045 PLN in tax. This reduces the real return by ~1 percentage point.

Are EDO bonds safe?

Yes — they're Polish Treasury bonds, guaranteed by the government. Default risk is minimal. They can be redeemed after 1 year (with loss of interest from the last settlement period).

How do I calculate my real return on savings?

Formula: real return = (1 + net interest rate) / (1 + inflation) - 1. Example: 5.5% deposit net after Belka tax is 4.455%. At 4.5% inflation: (1.04455 / 1.045) - 1 = -0.04%, essentially zero. Freenance shows this automatically in the context of your Runway.
