Pay-as-you-go versus funded pensions (Umlageverfahren and Kapitaldeckung)

Level 2 · Foundations

German termUmlageverfahren vs. Kapitaldeckung

Deep divesState Pension (Gesetzliche Rente)

An Umlageverfahren (pay-as-you-go system) uses current contributions and public funds mainly for current benefits, while a kapitalgedeckt (funded) system accumulates and invests assets for later benefits. Germany's statutory pension is predominantly pay-as-you-go. Occupational and private arrangements are often funded, though guarantees and risk-sharing differ by product [1][2].

Two financing logics

Pay-as-you-go is not “unfunded” in the sense of having no rules or assets. Contributors acquire legally protected pension rights, and the GRV holds a sustainability reserve. The distinction concerns how benefits are financed.

Question	Pay-as-you-go	Funded
What finances today's benefit?	Current workers, employers, and public funds	Previously accumulated assets and returns
Main economic exposure	Wages, employment, demographics, policy	Markets, interest rates, fees, inflation, provider structure
Does the member own a personal pot?	Not in the German GRV (gesetzliche Rentenversicherung — statutory pension insurance)	Sometimes, but legal ownership and guarantees depend on the arrangement
Can the system hold reserves?	Yes; a reserve does not change its main logic	Yes; assets are central to financing

Worked demographic example

Suppose 100 workers finance 50 pensioners. If the pensioner count later rises to 70 while wages and employment stay unchanged, the system must absorb the change through some combination of contributions, taxes, benefit rules, retirement ages, or productivity growth.

A funded plan faces a different shock. If its assets fall 20%, the effect depends on guarantees, time horizon, contribution flexibility, and who bears investment risk.

Why both can coexist

The two methods diversify different risks rather than eliminating risk. Pay-as-you-go links benefits to the future economy and workforce. Funding builds claims on assets but remains exposed to markets and institutions. Germany's three-pillar structure combines both logics.

What mainly finances current GRV pensions?

Each retiree's segregated investment accountCurrent contributions and federal fundsOnly returns from a sovereign wealth fund

What is central to a funded pension?

Accumulated and invested assetsNo exposure to markets or institutionsCurrent workers paying every current benefit directly

If pensioners increase relative to workers in a pay-as-you-go system, what may adjust?

Only historical contributionsContributions, taxes, benefit rules, retirement ages, or productivityNothing, because demographics are irrelevant

Why can pay-as-you-go and funded pillars coexist?

They expose households to different economic risksOne guarantees that the other can never changeThey are legally and economically identical
