Lesson 16 - Cash In vs. Cash Out
Cashflow is the movement of money in and out of your life. Cash in means the money that comes to you - salary, side hustles, gifts, refunds. Cash out means the money that leaves you - rent, bills, groceries, entertainment. If cash in is bigger than cash out, you build stability. If cash out wins, stress and debt grow.
Why cashflow matters
Many people focus only on how much they earn. But what truly matters is the gap between income and expenses. Someone making €2,000 but spending €1,950 has less freedom than someone making €1,400 but spending only €1,000. Cashflow is not just about numbers - it is about options and control.
Main story: Mark’s paycheck trap
Mark, a 23-year-old junior developer, earned €1,600 monthly. Every month he felt broke by the 20th. He thought the problem was his low salary. But when he tracked his cash in and cash out, he discovered the real issue: €300 on food delivery, €150 on Uber, and €120 on subscriptions. His cash in was fine - his cash out was the problem. By cutting delivery to €100, canceling two subscriptions, and walking more, Mark freed €300. Suddenly, he was not broke anymore. He saved €150 each month and used the rest for fun guilt-free. Mark learned that cashflow control starts with awareness, not just bigger paychecks.
Mini-case study 1: Netflix vs. income
A US survey showed that the average young adult spends $30 a month on streaming. It sounds small, but for someone earning $1,200, that is 2.5% of income. If paired with other unnoticed subscriptions, it can push cash out higher than expected. The lesson: even “tiny” expenses matter.
Mini-case study 2: Small business reality
A bakery in Germany earned €20,000 per month in sales. Cash in looked great. But rent, salaries, ingredients, and energy costs totaled €19,500. Cash out almost ate everything. The owner was left with €500, barely enough to reinvest. Despite high sales, weak cashflow kept the business fragile.
Mini-case study 3: Argentina inflation shock
In Argentina during 2019, inflation hit 50%. Families saw cash in rise in numbers, but cash out - the cost of food, rent, and transport - rose faster. Many ended up with negative cashflow even though their income doubled on paper. This shows that cashflow is not just personal but linked to wider economic conditions.
Visual: Example monthly cashflow
Here is how a €1,500 monthly cash in can look once expenses are subtracted.
This chart shows €1,500 income (green) and €1,400 expenses (orange). The €100 gap is positive cashflow.
