What is a Riester Rechner?

A Riester Rechner is a planning tool for Germany’s Riester pension system. It helps you estimate how much your private retirement plan could grow over time by combining your own yearly contributions with government support in the form of allowances and possible tax advantages.

Because Riester includes specific funding rules, many savers are unsure whether they are paying in enough to receive the full subsidy. A calculator gives you a fast way to check your contribution level and project a possible pension outcome.

How this calculator works

This page uses a simplified but practical model:

• It calculates annual state allowances (basic + child allowance).
• It estimates tax benefit based on your marginal tax rate and deductible limits.
• It adds all annual inflows and compounds them at your expected return rate until retirement.
• It also shows an inflation-adjusted estimate in today’s money.

Included assumptions

• Contributions and subsidies are treated as yearly payments.
• Tax benefit is estimated, not an official tax assessment.
• Returns are assumed to be constant year to year for projection purposes.

Key Riester inputs explained

1) Income and minimum contribution

To receive full allowance, savers generally need to contribute about 4% of previous gross income, minus allowances, while respecting legal limits and minimum own contribution rules. If your annual contribution is below this threshold, subsidies may be reduced proportionally.

2) Basic and child allowances

The standard basic allowance is typically granted per eligible adult contract. Child allowances depend on eligibility and birth year rules. This calculator lets you choose a child-allowance amount per child so you can model your own case.

3) Tax advantage

Riester contributions can generate a tax effect via special expense deduction (up to legal caps). In practice, the tax office compares the tax benefit with allowances and grants the better outcome. The model here approximates that annual effect for planning.

How to interpret your result

Focus on three outputs:

• Estimated end value: projected contract value at retirement age.
• Estimated real value: purchasing-power-adjusted amount after inflation.
• Contribution check: whether your own payment likely reaches full allowance level.

Ways to improve your Riester outcome

• Review your contribution each year after salary changes.
• Update child data and eligibility promptly to avoid missing allowances.
• Compare contract costs, guarantees, and fund options.
• Use annual statements and a Riester Rechner together for ongoing optimization.

Important note

This tool is educational and does not replace legal, tax, or pension advice. Exact Riester treatment can depend on contract type, individual tax profile, child benefit allocation, and regulatory updates. For binding numbers, consult your provider, tax advisor, or official pension resources.
