How to use the calculator
Enter your current wealth and your planned monthly contribution above, plus the expected return of your investment. The most important field is your desired monthly income – the amount you'd one day like to live on without having to work. From this, the calculator instantly computes the target wealth you need and shows you in how many years you'll reach it with your current values.
Under "Advanced options" you can adjust the withdrawal rate (default: 4%) and decide whether your contribution should rise each year (dynamic increase). Hover over a bar in the chart to see the wealth and contributions for that year – the dashed line marks your target wealth.
What does financial freedom mean?
Financial freedom means you no longer depend on earned income to cover your cost of living – instead, the income from your accumulated wealth covers your expenses. This isn't necessarily the same as retirement: many financially free people keep working anyway, but by choice rather than out of financial necessity.
The 4% rule, simply explained
The 4% rule is a rule of thumb from the so-called Trinity Study (1998), which examined what annual withdrawal rate a broadly diversified stock/bond portfolio has historically sustained over very long periods (30 years and more) without being depleted. The result: around 4% per year. From this you can work back to the wealth you need:
Target wealth = (desired annual income) / 4%
Put differently: you need roughly 25 times your desired annual expenses as wealth – which is why in the FIRE community (Financial Independence, Retire Early) the 4% rule is often called the "rule of 25" too.
How does the calculator work?
First, the calculator computes your target wealth from your desired income and the withdrawal rate. Then it simulates your contribution month by month: each month your contribution is added, and interest is credited proportionally on the existing amount. As soon as your simulated wealth reaches or exceeds the target wealth, the calculator shows you the corresponding year.
Which factors get you to the goal faster?
- Increase your contribution: the most direct lever – every additional euro you set aside each month immediately shortens your journey.
- Lower your expenses: works twice over, because a lower desired income both reduces your target wealth and can (indirectly, via a higher savings rate) increase your contribution.
- Return: even small differences in the annual return have a noticeable effect on the timing over many years.
- Withdrawal rate: a lower, more cautious withdrawal rate increases your target wealth and thus the time to reach it – but in return your wealth is more robust against bad market phases in retirement.
Risks and limits of the 4% rule
The 4% rule is a rough guide, not a guarantee. It is based on historical US market data from a specific period – future returns, inflation and the sequence of good and bad stock-market years (sequence-of-returns risk) can differ from it. Those who retire particularly early usually plan with a much longer withdrawal period than the originally studied 30 years anyway, which is why many in the FIRE community cautiously calculate with 3 to 3.5% instead of 4%. In addition, taxes and inflation are not factored into this calculator.
Frequently asked questions
What exactly does financial freedom mean?
Financial freedom means that the income from your wealth (e.g. interest, dividends or capital gains) is enough to cover your cost of living permanently – without you having to be gainfully employed. You then work because you want to, not because you have to.
What is the 4% rule?
The 4% rule goes back to the so-called Trinity Study and, simplified, states: if you withdraw no more than 4% of your invested wealth per year, your capital has historically lasted over very long periods with a broadly diversified investment. From this you can work back to the wealth you need: desired annual income divided by the withdrawal rate.
Is the 4% rule still realistic today?
That's debated among financial experts. The original study is based on historical US market data over a specific period – future returns, inflation and life expectancy can differ. Many today cautiously assume more like 3 to 3.5%. That's why you can freely adjust the withdrawal rate in the calculator via the advanced options.
Do I have to stop working completely once I reach the target?
No. Financial freedom doesn't necessarily mean you stop working immediately – for many it primarily means freedom of choice: you can cut back, change jobs or do something entirely different without becoming financially dependent on it.
Are taxes and inflation included in the calculation?
No. The calculator shows the gross development of your wealth without capital gains tax and without accounting for inflation. Your actually available net income after taxes is lower, and the real purchasing power of your target amount decreases over time due to inflation.
What return should I realistically assume?
That depends heavily on your chosen investment strategy and can't be seriously quantified across the board. For a rough orientation, set it conservatively and feel free to try several return scenarios in the calculator.
What does the dynamic increase of the contribution mean?
It means that your monthly contribution doesn't stay constant but rises by a fixed percentage each year – for example in line with expected salary increases. This can noticeably bring forward the point of your financial freedom.
What's the difference from a normal compound interest calculator?
The compound interest calculator shows you how a certain saving and investing behaviour develops over a duration you set. This calculator flips the question: it first determines the target wealth you need (based on your desired income and the withdrawal rate) and then calculates when you're likely to reach that goal with your contribution.
What does capital depletion mean compared to the normal 4% rule?
With the classic 4% rule you permanently withdraw only part of the income, and the wealth itself stays intact in principle forever. With capital depletion, on the other hand, you deliberately plan to use up your wealth completely over a defined period (the withdrawal period). This lowers the target wealth you need, but also means your money is used up at some point – so you should adjust the withdrawal period realistically to your expected life expectancy.
How accurate is the tax calculation in the calculator?
Deliberately simplified: the calculator grosses up the withdrawal with a fixed tax rate in order to reach your net desired income. More complex aspects of German tax law such as the advance lump sum (Vorabpauschale), partial exemption for funds or the annual saver's allowance are not modelled. For a binding assessment of your individual tax burden, consult a tax advisor.
This calculator is for non-binding orientation only and does not constitute investment, tax or retirement advice. The 4% rule is based on historical data and is no guarantee for the future. Taxes, inflation, fees and market fluctuations are not taken into account here. All information without guarantee.
