Note: This specific book (“Como Organizar Sua Vida Financeira” by Gustavo Cerbasi) is a Brazilian publication without a direct English edition. However, its core principles on financial engineering and budget mapping are universally applicable.

Through the previous readings, we established that money needs to flow into the asset column and that a part of everything you earn must be retained. However, the tactical execution of this runs into a common problem: the lack of organization.

This reading made me pay proper attention to the organization of finances and the mapping of expenses, constantly forcing myself to log expenses in a spreadsheet to maintain control.

If I were to summarize it: organization and discipline are more important than large earnings.

Mapping the Variables

You cannot optimize what you cannot measure. Financial lack of control is not just about spending more than you should, but also about spending blindly. Cerbasi categorizes this front very well, separating our costs into two blocks that need to be strictly mapped:

• Fixed Expenses: It’s not just the monthly electricity bill. It’s all expenses that repeat for three months or more, plus those with a set annual frequency, such as property taxes, vehicle taxes, and credit card or professional board fees.
• Occasional Expenses: This is where most people’s budgets break. These are car maintenance, home repairs, unforeseen medical appointments, and even gifts.

If you do not have predictability over occasional expenses, your financial planning is merely a look at the past.

Risk Management: PMS and PMR

For those who like to operate with margins of safety, the most valuable part of the book is the structuring of reserves. Cerbasi divides the famous “emergency fund” into two strategic levels.

The first line of defense is the Minimum Survival Equity (PMS). In Cerbasi’s own words:

“The minimum survival equity (PMS) is what you need to have simply to be able to reorganize your life in the event of unemployment, illness, or frustrated plans in your business activity. It is with this reserve that you will maintain your consumption standard until things normalize.”

The second line of defense is the Minimum Reserve Equity (PMR), which acts as the mathematical target for your peace of mind. As the author points out:

“The minimum reserve equity (PMR) should be a financial reserve equivalent to 12 times your family’s monthly consumption, assuming you are in a stable employment situation. Self-employed individuals, workers without formal employment ties, and professionals with reduced employability should have a PMR equivalent to 20 times their family consumption.”

Public service professionals or military personnel can operate comfortably in the 12-month range, while those in high-turnover private sectors or entrepreneurs need a 20-month “breathing room”.

Adequate Strategy for My Income Profile

The book addresses an important issue: setting up the appropriate financial planning for your financial profile. What does that mean?

If you are a professional whose income is extremely variable, you should outline a minimum income you receive monthly and an average income, as well as analyze if there is a seasonality in your capital inflow to plan according to these aspects.

The Price of Indiscipline

“A financial life full of debts makes you achieve far fewer dreams than you would with planning and discipline.”

For me, the obvious conclusion of this reading is that wealth is not the result of strokes of luck, but of cold and repetitive execution. Your budget must be treated as a protocol to be followed. And a well-designed protocol does not depend on motivation, only on discipline to be fulfilled.
