Germany’s pension system was built when a younger workforce could support an expanding welfare state. Immigration can ease the pressure of ageing, but productivity and the distribution of costs will determine what happens next.

In January 1957, the West German Bundestag approved a pension reform that would shape the country’s social system for generations. Konrad Adenauer was chancellor. West Germany was enjoying the economic expansion later associated with the Wirtschaftswunder. Wages were rising, and the government wanted pensioners to share in that prosperity.

The reform linked pensions more closely to wages and developed the pay-as-you-go principle under which current workers support current retirees. Germany called the relationship a Generationenvertrag, a contract between generations.

Nearly seventy years later, the contract remains central to German life. Yet the population supporting it looks different. The baby boom generation is retiring. Smaller generations are entering employment. Germany must finance more years of retirement for a growing elderly population.

The problem is no longer whether ageing will affect pension financing. It already does. Germany must decide how much additional responsibility belongs to working people and employers, and how much should be financed through taxation.

The Pension Promise Made in 1957

The 1957 reform helped turn statutory pensions into a more substantial source of old-age income. Adjustments followed earnings more closely so that retirees could share in rising prosperity. Financing moved progressively toward the Umlageverfahren, or pay-as-you-go model.

Employees and employers pay into statutory pension insurance. Current revenue largely pays current pensions instead of accumulating in separate individual investment accounts. The federal government also contributes from its budget.

In 2026, the statutory pension contribution rate remains 18.6% of covered gross earnings, normally split equally between employers and employees. Federal transfers help meet the system’s obligations.

When earnings and employment rise, contribution revenue generally improves. When a large generation retires, expenditure rises while growth in contributions may weaken. The system need not suddenly stop paying benefits: lawmakers can change rates and funding arrangements. But those decisions redistribute costs.

A Demographic Change Already Underway

Germany’s Federal Statistical Office published its 16th coordinated population projection in December 2025. Approximately 51.2 million residents were aged 20 to 66 in 2024. Under a scenario with moderate fertility and life expectancy and long-term annual net immigration of 250,000, this group would shrink by around four million by 2035.

Even a scenario with annual net immigration of 350,000 leaves roughly 3.2 million fewer residents in that age range. The share aged 67 and older is expected to rise from about one-fifth in 2024 to roughly one-quarter by 2035.

Those are projections, not promises about the future. They also do not directly count pension contributors. Some residents of working age are students; others are self-employed or belong to separate pension arrangements. Pension financing depends on actual earnings and the people contributing, not merely on an age bracket.

The broad pattern, however, is already visible: large generations are retiring and smaller generations are following them.

Immigration Helps, But It Cannot Stop Ageing

Migrants have supported Germany’s labour market for decades. Without inward migration, the demographic situation would be more difficult. New arrivals can fill vacancies and earn income that supports public finances.

Destatis calculates that net immigration of around 570,000 people aged 20 to 66 annually between 2025 and 2035 would be needed simply to prevent that age group’s population from declining. This is a demographic scenario, not a government migration quota or an estimate of immediately available pension contributors.

A foreign-trained nurse may need professional recognition. An engineer may spend months learning German before obtaining suitable employment. Parents might need childcare. Immigration policy matters, but what happens after arrival matters just as much.

My earlier article Germany Needs Foreign Workers. So Why Does Immigration Still Feel Like a Political Problem? examines some of those tensions.

Migrants also retire. A worker who arrives at thirty can contribute for decades and later acquire pension entitlements. Migration can improve the age structure. It cannot abolish ageing or permanently replace reforms to employment and pension financing.

Should Germans Work Beyond 67?

Germany has been gradually raising its standard pension age toward 67, with the transition completed for those born in 1964 or later. Longer working lives can increase contributions while limiting the number of years for which an individual draws a pension.

But two people of the same age may have very different capacity to continue working. A university lecturer may be able to adjust teaching hours. A construction worker whose back has suffered decades of lifting may have few comparable options.

Health and the physical demands of work affect retirement possibilities. Employers must also be prepared to train and retain older employees. Raising a statutory retirement age does not automatically create jobs for people in their late sixties.

Flexible arrangements could allow some older people to remain economically active. Workers with serious health limitations, however, need effective protections. Pension sustainability must account for both the financial value of longer careers and the uneven burden they can create.

Workers Germany Does Not Fully Use

Much of the political discussion focuses on people who might move to Germany. Less attention goes to residents who could work additional paid hours if their circumstances changed.

Women frequently interrupt careers or work part-time because they provide care at home. Such patterns can reduce lifetime earnings and therefore pension entitlements. The OECD’s Pensions at a Glance 2025 reports that average pensions received by women in Germany were 26% lower than those received by men in 2024.

Affordable childcare could increase opportunities to work. Older employees may also benefit from retraining or flexible schedules. None of this is free: care services and workplace changes require investment.

Employment is shaped not only by a person’s willingness to work but by whether institutions make that work possible.

Productivity Is the Missing Economic Question

A country can employ fewer people and still produce more. The difference depends on productivity, the value generated per hour or worker.

Germany’s manufacturing history shows how advanced equipment and skilled labour can sustain high output. Similar opportunities exist in public administration and services. Digital paperwork processing may release trained employees for more demanding tasks. New technologies could expand productive capacity if companies invest and workers receive training.

Artificial intelligence may contribute, but potential gains must not be counted as if they have already appeared in the national accounts.

Higher productivity does not automatically repair pension finances. Some gains may flow to profits rather than salaries. Statutory pension contributions depend heavily on insured earnings, while federal support relies on taxation. What matters is whether growth strengthens the revenue available to finance retirement.

The wider pressures on earnings and consumption are discussed in Germany’s Economy Is Recovering. Why Does It Still Feel Like a Crisis?.

Why Governments Struggle to Change Pensions

Retirees arrange their lives around expected pension payments. Many have little opportunity to rebuild savings if benefits fall. Younger contributors face uncertainty about what their own retirement will cost. Employers watch payroll expenses, and governments must account for competing claims on public revenue.

Raising contributions increases labour costs and reduces take-home pay unless something else changes. Larger federal transfers can mean higher taxes or less spending elsewhere. Restraining pension increases could leave some pensioners with less income relative to wages.

Germany’s Pension Package 2025 extended a safeguard for the standard pension level of 48% through 2031. That percentage does not mean each pensioner receives 48% of their final salary. It refers to a model pension after 45 years of average earnings, compared with average earnings under prescribed adjustments.

The safeguard protects a benchmark, but financing it still requires revenue. Pension law can preserve a promise; it cannot make that promise costless.

The 2026 Pension Commission

In June 2026, Germany’s government-appointed Alterssicherungskommission submitted 33 recommendations for retirement reform. The Federal Ministry of Labour published the report on 23 June.

The commission proposed a capital-funded statutory pension component inspired by Sweden. It also suggested gradually extending participation in statutory pension insurance to groups currently outside it, including certain self-employed workers. It discussed retirement age and contribution rules.

These are reform recommendations, not automatically enacted provisions. A funded component would take time to build assets and investment returns are uncertain. Adding contributors may increase current revenue, but those contributors normally gain future pension rights.

The proposals illustrate a shift from annual adjustments toward a wider discussion about how obligations are shared. The Federal Ministry’s commission report sets out the recommendations.

The Debate Extends Beyond Pension Payments

An ageing society also needs care workers and healthcare services. Families may spend more time supporting older relatives, which can limit paid work. Public money for pensions must be considered alongside other budget commitments.

Older people are not simply an economic burden. Some continue paid employment and many provide unpaid care to relatives. Those contributions may not appear as pension-insurance revenue, but they are part of everyday economic life.

The 1957 settlement sought to let pensioners share in a rapidly growing economy. The challenge now is sustaining that social commitment under different demographic conditions. No single generation created the change. Today’s workers did not design the system, and today’s pensioners cannot undo the country’s birth history.

The debate therefore concerns not only retirement age but the distribution of responsibility across the economy.

Who Will Support Germany’s Retirees?

Future workers will remain central to financing Germany’s pensions. But the outcome also depends on the quality of employment and whether productivity raises the income available to support older people.

Immigration can ease labour shortages when qualified newcomers find work. Better childcare and employment conditions could help residents already in Germany. Pension reform may change how the costs are shared. None is a painless substitute for the others.

The 1957 reform tied retirement security to the earnings of future generations. That connection survives. What has changed is how many people are expected to carry it.
