How is the minimum Riester contribution calculated?

To receive the full state allowance you must contribute 4% of your prior-year gross income, including the Zulagen. Your own contribution (Eigenbeitrag) is therefore 4% of income minus the Grundzulage and Kinderzulage you receive, subject to a 60 EUR floor and a 2,100 EUR cap on the total.

What are the Zulagen amounts?

The Grundzulage (basic allowance) is 175 EUR per year per saver. The Kinderzulage (child allowance) is 185 EUR per year for each child born before 2008 and 300 EUR per year for each child born in 2008 or later, paid to the parent receiving Kindergeld.

What is the Sockelbeitrag?

The Sockelbeitrag is the minimum own contribution of 60 EUR per year. Even if 4% of your income minus your Zulagen would be less than 60 EUR — or even negative for low earners with several children — you must still pay at least 60 EUR yourself to keep the full allowance.

Is there a maximum contribution?

Yes. The total Riester contribution that counts towards the allowance and tax deduction is capped at 2,100 EUR per year including the Zulagen. Contributing above 4% of income up to this cap can increase the tax deduction but not the Zulage.

What happens if I contribute less than the minimum?

If your own contribution is below the required amount, your Zulagen are reduced proportionally (gekürzt). For example paying only half the required Eigenbeitrag means you receive only half of the Grundzulage and Kinderzulage you would otherwise get.

Germany Riester Rente Contribution Calculator

A Riester-Rente contribution calculator that works out the Mindesteigenbeitrag — the minimum you must pay into your German Riester pension to receive the full state Zulage. It applies the 4%-of-prior-year-income rule, subtracts your Grundzulage and Kinderzulage entitlements, and enforces the 60 EUR Sockelbeitrag floor and the 2,100 EUR annual cap.

How it works

The state tops up Riester savings with allowances (Zulagen), but only if you pay your share. The required total is 4% of your prior-year gross income; your own contribution is that minus the allowances you receive:

zulagen     = grundzulage + sum(kinderzulage)
target4pct  = min(priorYearIncome * 0.04, 2100)
eigenbeitrag = max(target4pct - zulagen, sockelbeitrag = 60)
totalPaid   = eigenbeitrag + zulagen

The Zulagen are fixed: 175 EUR Grundzulage per saver, 185 EUR per child born before 2008, and 300 EUR per child born from 2008. The 4% target is capped at 2,100 EUR (including the Zulagen), and the own contribution can never fall below the 60 EUR Sockelbeitrag — even when a low earner with several children would otherwise owe nothing. Pay less than the required Eigenbeitrag and the Zulagen are cut proportionally.

Example and notes

On a prior-year income of 40,000 EUR with the Grundzulage and two children born from 2008: the 4% target is 1,600 EUR; the Zulagen are 175 + 300 + 300 = 775 EUR; the minimum own contribution is 1,600 − 775 = 825 EUR. Paying that 825 EUR yourself secures the full 775 EUR of state money, for 1,600 EUR flowing into the pension.

A low earner on 12,000 EUR with two young children has a 4% target of 480 EUR but 775 EUR of Zulagen — so the formula floors at the 60 EUR Sockelbeitrag, and paying just 60 EUR still unlocks the full allowance. All figures use the current Riester rules and are computed in your browser.
