This page compares financial outcomes for a Software engineer living in Hamburg, Germany, following the Independent and uneven life scenario.
A non-linear income path shaped by project-based work, variability, and self-managed risk. Flexibility is high, but consistency must be actively created rather than assumed.
Hamburg has a strong professional services and logistics economy, with above-average costs and solid income potential.
The comparison focuses on how changing the Income tax rate influences long-term results, while all other assumptions remain constant.

- Labor income grows annually at an average rate of 4%.
- The labor income tax rate varies between 0% and 30%.
