The Top 5 Countries With The World's Best Pension Systems (2025 Global Index)
Planning for retirement has never been a more complex global challenge, with aging populations and shifting economic landscapes forcing governments to adapt their retirement income systems. As of late 2025, the definitive answer to "Which country has the best pension?" remains the Netherlands, which has continued its multi-year streak at the top of the global rankings, despite undergoing one of the most significant pension reforms in its history. This analysis, based on the most current data from the Mercer CFA Institute Global Pension Index (MCGPI) for 2025, reveals the countries that best balance financial security, system integrity, and long-term sustainability for their citizens.
The top-ranked countries are not just financially secure; they offer powerful blueprints for other nations struggling to ensure their retirees maintain an adequate standard of living. These systems are characterized by a robust multi-pillar structure, mandatory occupational schemes, and high levels of transparency and regulation. The latest rankings highlight a global trend: the move towards more individualized, yet still collective, Defined Contribution (DC) plans, a massive shift exemplified by the Netherlands' bold move.
The 2025 Global Pension Index: The Five Best Retirement Systems
The Mercer CFA Institute Global Pension Index (MCGPI) evaluates 52 retirement income systems worldwide, using over 50 indicators across three key sub-indices: Adequacy, Sustainability, and Integrity. A high score signifies a world-class system that provides sound benefits, is financially sustainable, and has a high level of public trust. The following five countries represent the gold standard in global retirement planning, securing the coveted 'A' grade.
1. The Netherlands: The Reform Leader (MCGPI Grade: A)
The Netherlands consistently secures the number one spot, a remarkable feat given its ongoing transition under the new Future Pensions Act (Wet toekomst pensioenen). The Dutch system is historically known for its large, collective Defined Benefit (DB) schemes, but is now transitioning to a more individualized, contribution-based Defined Contribution (DC) structure.
- Key Components: The system rests on three pillars: the universal state pension (AOW), mandatory occupational schemes, and voluntary private pensions.
- The AOW State Pension: The basic state pension, the Algemene Ouderdomswet (AOW), provides a flat-rate benefit to all residents upon reaching the state retirement age, which is set at 67 for 2024, with future increases tied to life expectancy. For 2025, the gross monthly AOW amount for a single person is approximately €1,580.92.
- The DC Shift: Under the new legislation, defined benefits are no longer possible. The new DC schemes will feature a contribution rate capped at 30% of pensionable earnings, ensuring a high level of mandatory savings. This move aims to make the system more transparent and less susceptible to the financial burdens of longevity risk on employers.
2. Iceland: The Sustainability King (MCGPI Grade: A)
Iceland's pension system, often described as a "collective DC plan," is lauded globally for its exceptional sustainability scores. The country's small population and robust scheme design contribute to its high ranking, making it a model for long-term financial stability.
- Key Features: The Icelandic system also operates on a three-pillar structure: the basic state pension (old-age pension), mandatory occupational private pension schemes, and voluntary personal pension plans.
- Mandatory Schemes: The mandatory occupational schemes are the backbone of the system, requiring high contribution rates from both employers and employees.
- High Sustainability: Iceland is top-rated in the sustainability sub-index, demonstrating that its current benefits are likely to be maintained for future generations, a crucial indicator given global demographic shifts.
3. Denmark: The Three-Pillar Model (MCGPI Grade: A)
Denmark's system is frequently praised for its high level of pension adequacy, ensuring that retirees receive an income that allows for a comfortable standard of living. The Danish model is a classic example of a multi-pillar approach working effectively.
- Key Components: The system is comprehensive, including a tax-funded public pension, two statutory occupational schemes (most notably the earnings-related ATP pension), and voluntary private plans.
- The ATP Pension: The Arbejdsmarkedets Tillægspension (ATP) is a compulsory, earnings-related scheme that acts as a vital supplement to the basic state pension, ensuring broad coverage across the workforce.
- Adequacy Focus: The multi-layered structure is specifically designed to provide a high replacement rate, meaning the retirement income is a large percentage of the pre-retirement income.
4. Israel: The Middle East's Top Performer (MCGPI Grade: B+)
Israel's rapid ascent in the global rankings is a testament to its successful implementation of mandatory pension saving. While not an 'A' grade, Israel consistently ranks in the top four, leading the Middle East and Asia region.
- Mandatory Provision: The key to Israel's success is its mandatory pension insurance law, which requires all employees and employers to contribute to a pension fund. This ensures near-universal coverage.
- Focus on Integrity: The Israeli system scores highly on the integrity sub-index, reflecting strong regulation, good governance, and high levels of protection for plan members.
5. Australia: The Superannuation Success Story (MCGPI Grade: B+)
Australia’s retirement system, known as 'Superannuation' or 'Super,' is one of the most recognizable examples of a mandatory, privately managed DC system globally. It is a highly developed system with substantial assets under management.
- The Superannuation Guarantee (SG): Employers are legally required to contribute a percentage of an employee's ordinary time earnings to a Super fund. This rate has been steadily increasing, boosting the overall adequacy of the system.
- Drawbacks: While strong, the system often faces scrutiny over the complexity of regulations and the need for greater support for low-income earners, which slightly lowers its overall adequacy score compared to the Nordic models.
The Global Shift: Why Pension Systems Need Constant Reform
The success of the top-ranking countries underscores a critical truth: a world-class pension system is not static; it requires continuous monitoring and reform. The challenges facing all nations, regardless of their current ranking, are universal and stem from three main demographic and economic pressures:
The Triple Challenge: Longevity, Low Birth Rates, and Low Interest Rates
1. Longevity Risk: People are living longer, meaning retirement periods are extending. A system designed to support a 15-year retirement must now fund a 25- or 30-year retirement, placing immense pressure on financial sustainability. This is a primary driver behind the global trend of raising the state retirement age, as seen in the Netherlands and Denmark.
2. Declining Birth Rates: Fewer workers are contributing to the system to support a growing number of retirees. This imbalance severely impacts pay-as-you-go (PAYG) components, such as the basic state pension, forcing a greater reliance on pre-funded, occupational schemes.
3. Economic Volatility: Low-interest rates and market volatility make it harder for pension funds to generate the returns needed to meet their long-term liabilities. This is the core reason the Netherlands is moving away from the old DB model, which guaranteed a specific benefit regardless of market performance, towards a DC model where individuals bear more of the investment risk.
Lessons from the Best: Building a Sustainable Retirement Income System
For countries looking to improve their systems, the A-grade nations offer clear, actionable strategies focused on the three sub-indices of the MCGPI: Adequacy, Sustainability, and Integrity.
Focus on Adequacy: The Danish model proves the importance of a multi-pillar system that combines a basic state safety net with mandatory, earnings-related occupational schemes. This ensures that almost all workers, regardless of their employer, are accruing significant pension savings throughout their careers.
Focus on Sustainability: Iceland's success is a lesson in long-term planning. Their high contribution rates and pre-funded approach mean they have a vast pool of assets relative to their economy, making the system resilient to future demographic shocks. Improving the funding ratio of pension funds is paramount for all nations.
Focus on Integrity: Transparency, clear communication, and strong governance—hallmarks of the Dutch and Israeli systems—build public trust. When participants understand how their money is invested and regulated, compliance and confidence in the entire retirement income system increase dramatically. The Netherlands' move to a DC system, while complex, is intended to increase transparency by showing participants their individualized pot of savings.
In conclusion, while the Netherlands holds the title of the world's best pension system in 2025, its ongoing reform is a powerful reminder that even the best systems must evolve. The global future of retirement is moving toward mandatory, well-governed, and personalized Defined Contribution schemes, balanced by a robust state safety net, to ensure both financial security for today's retirees and sustainability for tomorrow's workers.
