How to Build a Retirement Portfolio — Asset Allocation by Age

Why you must take care of your own retirement?

The average Polish retirement from ZUS is 40–50% of your last salary — and this rate is declining. If you want to maintain your standard of living in retirement, you must build capital independently.

Good news: the earlier you start, the less you need to save. Compound interest does the rest.

Age-based allocation rule

The classic rule states: percentage of bonds in portfolio = your age.

• 30 years old → 30% bonds, 70% stocks
• 50 years old → 50% bonds, 50% stocks

It's a simplification, but captures the idea well: the closer to retirement, the less risk.

Modern approach

Today many experts use the formula: age minus 10 or 20 = percentage of bonds, because we live longer and need higher returns:

• 30 years old → 10–20% bonds, 80–90% stocks
• 50 years old → 30–40% bonds, 60–70% stocks
• 65 years old → 50–60% bonds, 40–50% stocks

Model portfolios by age

25–35 years — aggressive growth

35–50 years — balanced growth

50–65 years — capital protection

IKE and IKZE — your retirement accounts

IKE (Individual Retirement Account)

• 2026 contribution limit: ~26,000 PLN annually
• Benefit: no Belka tax (19%) on withdrawal after age 60
• Where to open: XTB, Bossa, mBank, TFI

IKZE (Individual Security Retirement Account)

• 2026 contribution limit: ~10,400 PLN annually (~15,600 PLN for self-employed)
• Benefit: deductible from income tax (savings up to 32% × contribution)
• At the end: 10% lump-sum instead of 19% Belka tax
• Where to open: Bossa, mBank, TFI

Strategy: maximize both limits

1. First IKZE — immediate tax relief
2. Then IKE — no tax on withdrawal
3. Surplus — regular brokerage account

Rebalancing — key to discipline

Check annually if allocation doesn't deviate from plan:

1. If stocks grew and constitute 80% instead of 70% — sell some and buy bonds
2. If stocks fell — buy more stocks (you're buying cheaper!)
3. Easiest: direct new contributions to the asset class that's "too low"

Annual rebalancing is optimal frequency — not too often (costs), not too rarely (deviations).

How much do you need to save?

Assuming 7% real annual return and goal of 1,000,000 PLN in retirement:

The earlier, the easier. 380 PLN monthly from age 25 will give you a million in retirement.

Common mistakes

1. Postponing the start — "I'll start next year" costs you thousands
2. Too conservative portfolio at young age — you lose growth potential
3. No rebalancing — portfolio "drifts apart"
4. Panic in bear market — selling at the bottom is the worst thing you can do
5. Ignoring IKE/IKZE — you give 19% of profits to the state
