Simulation Overview
This simulation varies a single parameter while keeping all other assumptions constant.
Base scenario assumptions
- The simulation starts at age 30 and runs until age 65.
- The initial annual income is €25,200.
- Income grows annually at an average rate of 4%.
- An income tax rate of 30% is applied to gross income.
- The saving rate varies between 5% and 25%.
- Minimum annual living expenses are €12,000.
- Savings are invested with stochastic annual returns.
- The average annual return is 6%, with year-to-year variability.
- All values are expressed in real terms, assuming average annual inflation of 2%.
- The simulation includes stochastic life events such as unemployment, and health issue.
- These events may temporarily affect income, expenses, or net worth.
- Financial independence is defined as having net worth equal to 25 times annual expenses.
- Bankruptcy is triggered if net worth remains below €0 for 2 consecutive years.

Scenario Comparison
Results are shown as a realistic range. P10 represents a pessimistic outcome (bad years, poor returns), while P90 represents an optimistic outcome (strong markets, good timing). Most simulations fall between these two values.
