I developed an intuitive, cross-platform tool to calculate net salaries in Germany. It simplifies the complexity of taxes, deductions, and social contributions while keeping a clean, minimalistic design. With straightforward functionality and clear visualizations, it helps users easily understand how their gross salary breaks down into take-home pay.
I have built a similar one two years ago, but it runs in the browser: https://allaboutberlin.com/tools/tax-calculator
Respect for putting in the work. It's surprisingly difficult to get all the calculations right, at least the first time. Keeping it updated is another story.
