Software engineer in Barcelona · Independent and uneven
This page compares financial outcomes for a Software engineer living in Barcelona, Spain, 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.
Barcelona combines a broad service and tech market with elevated living costs relative to the Spanish national average.
The comparison focuses on how changing the Saving rate influences long-term results, while all other assumptions remain constant.

- The initial annual labor income is €27,216.
- Labor income grows annually at an average rate of 4%.
- A labor income tax rate of 30% is applied to gross earnings.
