Your Frau Wohlstand Lab

What would you like to calculate today?


Here are your six calculators, all in one place. You enter your amount, your time frame and your assumptions. The formulas run in the background and you get your numbers straight in euros.

Maybe you’re working with €5,000 today, €25,000 later and €100,000 at some point. You can change any number, compare different scenarios and come back any time.

Your numbers

Where would you like to start?

Start with the question that interests you most.

Why 5%, 8%, and 12%?

These example figures come from my everyday copytrading — so you can see directly what euro amounts stand behind your own capital. I explain the strategy, leverage, and risk in full further down, under Copytrading.

Calculator 01

What could my money become?

Here you work out how your capital would develop over time under a given return assumption.

You decide the return. 2%, 5%, 8% and 12% are calculation examples. The result is a mathematical projection.
Which return would you like to try? Choose a value or enter your own number.
The higher the assumed return and the longer the time frame, the more the calculation changes. This projection alone says nothing about how achievable it is or its risk.

Calculated difference

Try the same calculation with a different return.

It's in a direct comparison that you notice how much a few percentage points or a longer time frame change the result.

Calculator 02

What does inflation do to my money?

The account balance alone says little about what you'll still be able to buy with this money in a few years. That's exactly what this calculator works out.

Account balance after the time frame
Change in purchasing power

The account balance doesn't tell you much about this at first.

The number can look similar for years, while you can buy less and less with the same money.

Calculator 03

How much capital do I need for a set amount per month?

Enter what you'd like to come out of your capital each month. The calculator shows you what capital would mathematically need to stand behind it at your chosen return.

Net return in this calculator This means the return after any fees you've already accounted for, and before your personal taxes.
Which monthly net return would you like to use? The values serve as calculation examples.
The calculator shows the math behind your assumption. A higher return changes the required capital size just as strongly.
Capital needed, calculated
At 2% per month
At 5% per month
At 8% per month
At 12% per month

The four results are far apart.

A few percentage points change the required capital size massively. And that's exactly what makes it interesting, at some point, to ask which returns actually occur in practice.

Want to make sense of your numbers? Then send them straight to me.

Your monthly amount, your return assumption and the result are automatically carried over into WhatsApp.

Calculator 04

How many euros are 2%, 5%, 8% or 12% of my money?

There's no long time frame here and no compound interest effect. You're simply translating a return into euros.

Which return would you like to use?
For your amount, that would be
2%
5%
8%
12%
Calculator 05

What happens when I pay out profits?

You can leave profits entirely in the capital, use part of them, or pay out everything. Here, four variants run side by side with the same starting numbers.

100/0, 75/25, 50/50 or 0/100 For each variant you'll see how much capital would be left at the end, how much has already been paid out, and what both together add up to.
Which monthly net return would you like to use?
Net return here means: after fees and before personal taxes.
Reinvest 100%
Reinvest 75% / pay out 25%
Reinvest 50% / pay out 50%
Pay out 100%

75/25 and 50/50 give you a bit of both.

With both variants, part of the profit already reaches you. At the same time, capital stays in place for the next round.

Want to look at your variant with me? Send me the numbers.

Your figures and the four results are sent along automatically.

Calculator 06

How long does my money last with regular withdrawals?

Enter how much you'd like to take out each month. You'll then get the capital level for your chosen time frame and the calculated reach of your entire sum.

Which monthly net return would you like to use?
Net return here means: after fees and before personal taxes. 0% is possible too.
Remaining capital
Calculated reach
Monthly withdrawal

Want to look at your numbers with me? Just send them over.

Starting capital, withdrawal, return assumption and reach are right there in your message.

If you want to think further after the numbers

And how do I use copy trading?

The calculators give you a mathematical scenario. I use copy trading myself to put my existing capital to work, without analysing charts every day and placing individual trades myself.

My capital sits in my own broker account. The account is connected to a trading strategy, and that strategy’s trades are executed automatically in my account.

The strategy I use works with 24x leverage. That amplifies both positive and negative movements. That’s why, for me, possible profits, losses and the risk of a total loss always belong on the table together.

On my copy trading page I walk you through how it works, our results so far and the risks, in full. That way you can decide in your own time whether you want to look into it further.

What’s behind the numbers?

If you first want to understand what is actually behind forex, copy trading and all those numbers: that is exactly why I wrote “Peace of Mind”.
