How This Calculator Works
Enter your current Riester value, the return you expect, and the years to retirement. The calculator compounds the balance and shows the projected value and the growth. The Riester's appeal isn't just investment growth — it's the state support: annual bonuses (Zulagen), including a generous child bonus, plus a possible extra tax deduction, top up what you pay in.

Worked Example
A €20,000 Riester growing at 4% for 20 years reaches about €43,822 — roughly €23,822 of growth, before counting the state bonuses. The Riester-Rente is a government-promoted private pension in Germany, aimed at employees and others covered by the statutory pension. Its distinctive feature is direct state support: a basic annual allowance (Grundzulage) plus a child allowance (Kinderzulage) for each eligible child are paid into your contract, and high earners may deduct contributions as special expenses (Sonderausgaben) if that gives a bigger benefit than the bonuses. In return, the pension is taxed as income when paid out.
Key Insight
The Riester-Rente is one of Germany's main subsidised pension pillars, and its value comes far more from the state bonuses than from raw returns. The subsidy structure: to get the full Zulagen you must contribute a minimum percentage of your prior-year income (with a cap), and in return you receive a fixed annual Grundzulage plus a Kinderzulage for each eligible child — the child bonus is especially generous, which is why Riester is often most attractive for families with children. Separately, contributions can be claimed as special expenses (Sonderausgaben) up to an annual ceiling, and the tax office applies whichever is better for you (Günstigerprüfung) — the bonuses or the tax saving — so higher earners may gain extra relief beyond the bonuses. Product types vary: classic Riester insurance, Riester bank savings plans, Riester fund savings plans (higher growth potential), and Wohn-Riester (using the subsidy toward owner-occupied housing). A defining safeguard is the capital guarantee — at the start of payout the contract must provide at least the sum of contributions plus bonuses, which limits how aggressively it can invest and has been criticised for capping returns in a low-rate era. The trade-offs and criticisms this calculator doesn't capture: payouts are taxed as income in retirement (deferred taxation), products can carry high fees that eat into returns, the rules are complex, and early termination or non-qualifying use means repaying the subsidies. This calculator models a single existing value compounding at a constant rate with no further contributions and omits the Zulagen (which materially boost the real outcome), fees, and the payout tax; in practice add your contributions and the annual bonuses, watch the fees, and remember the pension is taxed when drawn.
The Zulagen structure and the 4% rule
To receive the full Riester subsidies (Zulagen), you must contribute at least 4% of your prior year's gross income annually, with a personal contribution capped at €2,100 per year (Zulagen and own contribution combined). Contribute less than 4%, and the Zulagen are proportionally reduced.
The Grundzulage (basic subsidy) is €175 per year per saver. On top of that, the Kinderzulage (child subsidy) is €185 per year for each child born before 2008, or €300 per year for each child born from 2008 onwards — credited to whichever parent receives child benefit (Kindergeld). For young first-time Riester savers, there's a one-off €200 Berufseinsteiger-Bonus in the first contribution year.
Concrete example for a couple with two children (one born 2005, one born 2012) and the husband on €40,000 gross income: minimum contribution to get full Zulagen is 4% × 40,000 = €1,600/year. Of that, €175 (Grundzulage husband) + €175 (wife if also enrolled) + €185 (older child) + €300 (younger child) = €835 comes from the state. Net out-of-pocket contribution to get €835 of state money: only €765. That's a guaranteed 109% return on the first €765 contributed each year — before any investment return.
The 2027 reform: a contribution-proportional model
From 1 January 2027, the Riester regime is being fundamentally reformed. The fixed €175 Grundzulage will be replaced by a contribution-proportional subsidy: 30 cents per euro contributed up to €1,200, then 20 cents per euro up to €1,800 — capping at a higher annual Zulage for high contributors than the current €175 base.
Practical impact: under the new model, savers who contribute the maximum eligible amount can receive up to ~€500/year in basic Zulagen vs €175 today, while small contributors (those who pay in only the minimum to qualify) get proportionally less. This shifts the regime to favour those who can save more.
Child subsidies are also being raised — exact figures still being legislated as of mid-2026. Existing contracts will be transitioned automatically. Anyone considering opening a Riester contract now should weigh the bird-in-hand 2026 Zulagen against the structural improvements coming in 2027, and check the product's flexibility to adapt to the new rules.
Tax deduction vs Zulagen: Günstigerprüfung in practice
Contributions can also be claimed as Sonderausgaben (special expenses) on the income tax return up to an annual ceiling of €2,100. The tax office automatically computes both routes — Zulagen vs tax deduction — and applies whichever gives the bigger benefit (the so-called Günstigerprüfung).
For low and middle earners with children, the Zulagen route typically wins (especially with the generous Kinderzulage). For high earners without children, the tax deduction is usually better — a high-rate taxpayer paying €2,100 saves roughly €840 in income tax at the top rate, more than the €175 Grundzulage alone.
Critical caveats this calculator omits: the eventual pension payout is taxed as ordinary income in retirement (deferred taxation), product fees can compound against returns, and the contract carries a capital guarantee — which limits how aggressively it can invest and has historically capped long-run yields. The Riester product range varies from low-cost insurance to fund-based and Wohn-Riester (using the subsidy toward owner-occupied housing) — fit the product to your circumstances rather than assume Riester is a single thing.
Annual Riester Zulagen by family configuration (2026)
Subsidies paid into the contract each year, assuming minimum 4% contribution to unlock the full amount. For dual-Riester couples both spouses count.
| Family situation | Grundzulage | Kinderzulage | Total Zulagen / year |
|---|---|---|---|
| Single, no children | €175 | €0 | €175 |
| Single, 1 child (born 2010) | €175 | €300 | €475 |
| Single, 2 children (both ≥2008) | €175 | €600 | €775 |
| Couple, no children (both Riester) | €350 | €0 | €350 |
| Couple, 2 children (both ≥2008) | €350 | €600 | €950 |
| Couple, 3 children (all ≥2008) | €350 | €900 | €1,250 |
Plus €200 one-off Berufseinsteiger-Bonus in the first year if under 25. Reform from 2027 will replace the €175 fixed Grundzulage with a contribution-proportional subsidy.
Frequently Asked Questions
How is Riester growth calculated?
Compound the value at the expected return over the years: value = amount × (1 + rate)^years. €20,000 at 4% for 20 years grows to about €43,822, roughly €23,822 of growth — before the state bonuses (Zulagen), fees, and the income tax due on the payout.
What is the Riester-Rente?
A government-subsidised private pension in Germany for employees and others in the statutory pension system. Its defining feature is state support: an annual basic allowance plus a child allowance paid into your contract, and a possible extra tax deduction. The pension is then taxed as income when paid out.
What are the Riester bonuses?
The Zulagen: a fixed annual Grundzulage (basic allowance) plus a Kinderzulage for each eligible child. To receive the full amount you must contribute a minimum percentage of your prior-year income. The child allowance is generous, making Riester especially attractive for families with children.
Is the tax deduction or the bonus better?
It depends on income. Contributions can be claimed as special expenses (Sonderausgaben) up to a ceiling, and the tax office automatically applies whichever gives the bigger benefit — the bonuses or the tax saving (Günstigerprüfung). Higher earners often gain extra relief from the deduction beyond the flat bonuses.
What are the drawbacks of Riester?
Payouts are taxed as income in retirement, products can carry high fees, the rules are complex, and the capital guarantee can cap returns. Early termination or non-qualifying use means repaying the subsidies. So weigh the generous bonuses (especially with children) against fees and the deferred tax when deciding.

Methodology & Review
The future value compounds a Riester lump sum at the annual return over the years, compounded annually. It assumes a single starting amount with no further contributions and a constant return, and does not add the state bonuses (Zulagen), model fees, or compute the income tax due on the pension payout.
