Evaluate a private pension plan

The German three-pillar system

German retirement provision is built on three pillars. The first is the statutory pension (gesetzliche Rentenversicherung), funded by mandatory contributions of 18.6% of gross salary in 2025, split evenly between employee and employer. The second is occupational provision (betriebliche Altersvorsorge), arranged through your employer. The third is private, individual provision, ranging from state-subsidised insurance products to ordinary investment portfolios.

The reason a third pillar matters so much is the projected replacement rate. The statutory pension is widely expected to cover only about 45 to 48 percent of your final working salary. The difference between that and the income you actually need in retirement is the Rentenluecke, and closing it is the entire purpose of private and occupational provision.

Why expats especially need a portable private layer

Statutory pension entitlements are tied to your contribution record in a given country. If your career spans several countries, your German record may be short and your entitlements scattered across systems. Within the EU, periods can often be aggregated, but outside the EU much depends on bilateral social-security agreements, and gaps are common.

A privately owned, individual pension plan does not depend on a single employer or a single country's social system. You own the contract, you control the contributions, and depending on the vehicle you can often keep it running or paid-up if you leave Germany. For someone whose future location is uncertain, that portability and ownership is a strong argument for building the private pillar early rather than relying on a state record that may never become substantial.

Riester, Ruerup and private options briefly

Riester-Rente is aimed primarily at employees paying into the statutory system and at families. You contribute and the state adds annual allowances, with extra bonuses for each child, plus possible tax relief. It is heavily subsidised but comes with rules, limited flexibility and conditions that can be awkward for someone who may leave Germany.

Ruerup-Rente (also called Basis-Rente) was designed mainly for freelancers and the self-employed who are not in the statutory system. Its main attraction is large tax-deductibility of contributions, but the payout must be taken as a lifelong annuity and the capital cannot simply be withdrawn, so it is comparatively rigid.

Unsubsidised private pension plans (private Rentenversicherung) and ordinary investment-based provision sit alongside these. A private Rentenversicherung is flexible, individually owned and often more straightforward to keep across a move abroad, with tax advantages on the eventual payout. The best choice depends on your employment status, your tax bracket and how much value you place on subsidies versus flexibility and portability, which is exactly why this item is worth evaluating rather than guessing.

Expat-specific pitfalls

Do not assume a product that suits a lifelong German resident suits you. Riester in particular can be unattractive if you are likely to emigrate, because leaving the EU/EEA can trigger repayment of the state subsidies. Check the rules before signing.

Watch costs and flexibility. Some pension and life-insurance products carry high upfront and ongoing charges that quietly erode returns over decades; favour transparent cost structures and the ability to pause, reduce or transfer contributions. And do not let the private pillar crowd out simpler steps: a low-cost investment portfolio (see the index-fund and investment-account items) can be part of the third pillar too.
