The state pension alone is often not enough to maintain your usual standard of living in retirement. A private pension calculator gives you a precise picture of your potential pension gap and supports you in planning your additional retirement provision. Discover how you can gain clarity about your financial future in just a few clicks.
The topic in brief and concise terms
A private pension calculator helps identify your personal pension gap by comparing your expected retirement income with your desired needs.
Taxation of private pensions is usually advantageous in the payout phase through the income portion or the half-income method, although contributions to new contracts are rarely tax-deductible.
When choosing a private pension insurance policy, look for low costs (cost ratio below two per cent), flexibility and transparency; net tariffs can bring significant savings.
Quick check: What a private pension calculator can do
A private pension calculator is an online tool that calculates your expected retirement pension. It takes into account your current financial situation and planned retirement provision measures. Many Germans underestimate their pension gap by up to 30 per cent. With the calculator, you can identify this gap early and take countermeasures. This gives you a solid basis for planning your finances in retirement.
Understanding how it works: How the private pension calculator works out your pension
The private pension calculator requires a number of key details to analyse your retirement situation. These include your date of birth, your current monthly net income and any existing pension entitlements. Based on this data, the calculator simulates your future pension and shows the difference to your desired income in retirement. Many calculators also take inflation into account, which can reduce your purchasing power by an average of two per cent per year. Some tools allow you to run through different scenarios, such as earlier retirement. For a precise calculation of the state pension, factors such as earnings points, the access factor and the current pension value (since July 2024 at 39.31 euros) are included. Understanding these mechanisms helps you interpret the results more accurately and find the optimal contribution strategy.
Interpreting the results: recognising and closing the pension gap
The central result of a private pension calculator is the display of your personal pension gap. This gap is the difference between your last net income before retirement and the total of your statutory and any existing private pension entitlements. As a rule of thumb, around 80 per cent of your last net income is needed to maintain your usual standard of living in retirement. The calculator shows you how far you are from this target. If your projected total pension, for example, is EUR 1,500, but your required income is EUR 2,000, your monthly gap is EUR 500. This information is crucial for understanding the need for additional private pension insurance and determining its amount. This allows you to make an informed decision about whether you would like to receive your private pension insurance later as a pension or as a lump sum.
Retirement provision at a glance: Which pension models the calculator can cover
A good private pension calculator can incorporate various forms of retirement provision into its calculations. In addition to the state pension, these often include classic private pension insurance policies with a guaranteed rate of interest or unit-linked pension insurance policies. With traditional contracts, the interest rate is often low at present; for example, the guaranteed interest rate in 2025 was only one per cent for new policies. Unit-linked policies offer higher return potential, but also carry risks. The calculator helps determine the necessary savings amount for the desired supplementary pension, regardless of whether you are aiming for a unit-linked option or a more security-oriented solution. It is important to take the different layers of retirement provision into account.
The following aspects are relevant when making your selection:
Risk tolerance: How much fluctuation can you accept in return for potentially higher returns?
Flexibility: Do you need options for additional contributions or withdrawals?
Guarantees: How important is a guaranteed minimum pension to you?
Cost structure: Pay attention to initial, administration and fund charges.
Term: Long-term contracts benefit more from compound interest.
These considerations influence the choice of the right product, whose effectiveness a calculator can simulate.
Expert knowledge: Tax treatment of your private pension
The tax aspects of a private pension insurance policy are an important factor that a private pension calculator does not always reflect in detail, but which is nevertheless relevant to the overall picture. Contributions to private pension insurance policies taken out after 2004 are generally not tax-deductible. An exception may apply to older contracts (taken out before 2005), for which, under certain conditions, up to 88 percent of the contributions could be claimed as special expenses. The real tax advantages often only become apparent at the payout stage. With a lifelong pension payment, only the so-called taxable portion of the income is taxed. This depends on the age at the start of the pension; at age 67, for example, it is only 17 percent. For a lump-sum payment from contracts taken out from 2005 onwards, the half-income procedure applies if the contract has run for at least twelve years and the payout takes place no earlier than age 62: only half of the earnings are then taxable. Information on the correct declaration in the tax return for retirement provision contributions is useful here. The question of whether the private pension is subject to health insurance contributions should also be clarified.
Legal framework and consumer tips for your provision
The private pension insurance is based on solid legal foundations such as the German Civil Code (BGB), the Insurance Contract Act (VVG) and the providers' General Terms and Conditions (AVB). These govern contract conclusion, cancellation periods and obligations to provide benefits. A precise comparison of at least three offers is essential before taking out a policy. Pay attention to the cost ratio: if it is above two per cent while expected returns are low, caution is advised. Net tariffs, where a one-off fee (often EUR 1,000 to 1,500) is paid instead of ongoing commissions, can save tens of thousands of euros in the long term. A private pension calculator is the first step in clarifying your needs; selecting the right product requires further research and, where appropriate, a consultation on pension solutions. Also consider a private supplementary pension.
Important criteria for the comparison are:
Effective costs: How high are the total costs over the term?
Flexibility: Are top-ups, withdrawals or contribution adjustments possible?
Level of guarantees: What proportion of your contributions is guaranteed?
Return opportunities: Which types of investments are used (e.g. ETFs with costs often of only 0.2 to 0.5 per cent)?
Survivors' cover: Are there arrangements in the event of death?
Transparency: Are all terms and costs clearly understandable?
Careful review of these points protects you from unwelcome surprises.
A private pension calculator is more than just a calculation tool; it is your first adviser for sound retirement planning. With just a few entries, it highlights the need for private action and quantifies your individual pension gap. Use these insights to run through different scenarios: What happens if you retire earlier or adjust your savings rate by 50 euros a month? The calculator’s results form the basis for a conversation with an expert. They can help you choose the right products, whether a traditional, unit-linked or state-subsidised pension insurance. Bear in mind that the return on a private pension insurance policy also depends on how long you live and receive pension payments. Start planning early – even small monthly contributions can amount to a considerable sum over 30 to 40 years. Württembergische Versicherung states that, for childcare in the first three years of a child’s life, pension entitlements equal to one earnings point per year are credited. This is an aspect that can be taken into account in the overall assessment of your retirement provision. With the information from the calculator and professional advice, you can make the right decisions for a financially secure future.

At what age should I use a private pension calculator?
It makes sense to use a private pension calculator as early as possible, ideally when you start your career. The earlier you start planning for retirement, the lower the monthly contributions can be to reach your goal.

Some private pension calculators also include subsidised retirement savings products such as Riester or Rürup pensions in the calculation, or offer separate calculation tools for them.
What happens to my private pension if I cancel it early?
An early cancellation is often associated with financial disadvantages, as high initial setup costs are incurred especially in the first few years and the surrender value may be low.
How do I find the best private pension calculator?
There is no universally 'best' calculator. Look for transparency regarding the calculation basis and make sure the calculator comes from a trusted source. Use it as guidance and for an initial assessment of your pension gap.
What documents do I need for the private pension calculator?
You will usually need details of your date of birth, your current net income, your latest pension information from the German Pension Insurance, and, where applicable, information on existing private or occupational pension contracts.
