About PensionRetraite

PensionRetraite was founded with a single, clear objective: to give every worker in the world a reliable, free, and instantly accessible way to understand what their retirement will look like financially. Pension systems are among the most consequential yet least understood aspects of personal finance. Whether you are a salaried employee in France navigating the complexities of the regime general and AGIRC-ARRCO, a self-employed professional in Germany trying to understand Riester versus Ruerup, or an expatriate in Switzerland weighing the three-pillar system, the rules that determine your future income are dense, fragmented, and often buried in bureaucratic language.

We believe that understanding your pension should not require hiring a financial advisor or spending hours reading government documents written in legal jargon. Our calculators translate the official formulas, contribution schedules, eligibility thresholds, and tax rules of each country into interactive tools that produce personalized results in seconds. Every calculator on PensionRetraite is built by studying the primary legislative sources, official rate tables, and actuarial parameters published by each country's pension authority. We cross-reference these with peer-reviewed economic research and data from organizations like the OECD, the European Commission, and national statistical institutes.

The platform currently covers sixteen countries spanning Europe, North America, Asia-Pacific, and Africa. For each country, we provide at minimum two dedicated simulators: one for the public or state pension system and one for private or supplementary retirement savings. This dual approach reflects the reality that retirement income in virtually every developed economy comes from multiple sources, and understanding only one piece of the puzzle is not enough to plan effectively.

Building a pension calculator that people can trust requires more than plugging numbers into a formula. Pension systems are living constructs that change with every reform, every revaluation coefficient update, and every adjustment to contribution ceilings. Our development process begins with a thorough reading of the primary legal texts governing each country's pension system. For France, that means the Code de la securite sociale and the AGIRC-ARRCO accords nationaux interprofessionnels. For Germany, it means the Sozialgesetzbuch VI and the annual Rentenanpassungsverordnung. For the United States, it involves the Social Security Act and the annual COLA adjustments published by the SSA.

Once the legal framework is established, we translate the rules into mathematical models that account for all the variables a real worker would encounter: salary history, contribution duration, age at retirement, inflation expectations, tax brackets, and in the case of private savings, investment returns across different risk profiles. We then validate our models against the official calculators provided by government agencies wherever they exist. When discrepancies arise, we investigate until the source is identified and resolved, whether it is a rounding convention, a transitional provision, or an edge case in the eligibility criteria.

Every calculator includes clear disclosures about the assumptions embedded in the model, the date of the last legislative update incorporated, and the limitations of the simulation. We are transparent about the fact that these are estimates, not guarantees. Pension outcomes depend on future legislative changes, economic conditions, and individual career trajectories that no model can predict with certainty. Our goal is to provide the most informed starting point possible.

Pension systems around the world follow fundamentally different architectures, and understanding these differences is essential for anyone who has worked in multiple countries or is considering retirement abroad. The three most common models are pay-as-you-go (PAYG) defined benefit systems, funded defined contribution systems, and hybrid models that combine elements of both.

In France, the regime general provides a PAYG defined benefit pension calculated from the best 25 years of earnings, combined with mandatory complementary points-based pensions through AGIRC-ARRCO. In Germany, the gesetzliche Rentenversicherung uses an earnings points system (Entgeltpunkte) where each year of contributions at the average salary earns one point, and the pension is calculated by multiplying total points by a current pension value (Rentenwert) adjusted annually. In the United States, Social Security benefits are based on the highest 35 years of indexed earnings, with a progressive benefit formula that replaces a higher percentage of income for lower earners. In Switzerland, the three-pillar system combines a universal state pension (AHV/AVS), mandatory occupational pensions (BVG/LPP), and voluntary private savings (Pillar 3a).

These structural differences mean that a worker with identical earnings in different countries can face dramatically different retirement outcomes. Our calculators model each system's specific rules, contribution rates, benefit formulas, and eligibility criteria so users can understand what their pension will look like based on where they have worked and contributed.

Our calculators are built on data from the following authoritative sources, verified and updated with each legislative change:

• OECD Pensions at a Glance: Comparative data on replacement rates, contribution rates, and retirement ages across all member countries.
• National pension authorities: L'Assurance Retraite (France), Deutsche Rentenversicherung (Germany), Social Security Administration (USA), AHV/AVS (Switzerland), State Pension Service (UK), and their equivalents in all 16 covered countries.
• European Commission: Ageing Reports and pension adequacy assessments for EU member states.
• National statistical institutes: INSEE (France), Destatis (Germany), ONS (UK), and others for life expectancy, wage growth, and inflation data used in long-term projections.

Every formula in our models is traceable to a specific legislative text or regulatory publication. We document the version date of each data source on the corresponding calculator page, so users always know how current the underlying parameters are.

The OECD estimates that the average net pension replacement rate across its 38 member countries is approximately 62% of pre-retirement earnings, but this figure conceals enormous variation. In some countries, public pensions alone can replace over 80% of previous income; in others, the replacement rate barely reaches 30%, making private savings essential. The gap between what workers expect to receive and what they will actually receive in retirement is one of the most significant financial risks individuals face.

Starting to plan early has a profound impact. Thanks to the power of compound returns, a worker who begins saving for retirement at age 25 needs to set aside roughly half as much each month as someone who starts at 35 to achieve the same retirement income. Yet most people do not begin seriously planning until their 40s or 50s, often because pension systems are opaque and the information needed to make informed decisions is buried in bureaucratic documents. PensionRetraite exists to change that by making pension projections instant, transparent, and accessible to everyone, regardless of age or financial literacy.

Trust in a financial tool is earned through transparency, accuracy, and alignment of incentives. PensionRetraite is an independent, editorially driven platform. We do not sell financial products, we do not accept commissions from pension providers, and we do not steer users toward any particular investment decision. Our calculators are free to use, with no registration required and no data collected. The entire computation happens in your web browser, which means your salary, age, savings, and other personal inputs never leave your device.

The platform is built and maintained by Radif Partners with a background in quantitative finance and data-driven product development. Every calculator undergoes rigorous testing against official government tools and published pension tables before launch. When pension laws change, we update the affected calculators promptly and note the date of the last update on each page. We are committed to maintaining the highest standard of accuracy and editorial integrity in everything we publish.

Retirement planning is a global challenge. The OECD estimates that the average pension replacement rate across its member countries is approximately 58 percent of pre-retirement earnings, but this figure masks enormous variation between countries and within countries depending on income level, career pattern, and the interaction between public and private pension pillars. Our roadmap includes expanding coverage to additional countries, introducing scenario comparison tools that let users model different retirement strategies side by side, and deepening the educational content that accompanies each calculator.

We are also working on multilingual support for every country module. Currently, most countries are available in their native language as well as English and French. Our goal is to ensure that expatriates, cross-border workers, and international professionals can access pension information in the language they are most comfortable with, regardless of where they work or where they plan to retire.
