📊 What is a personal budget?
A personal budget is like a map of your money: it shows everything that comes in (your income) and everything that goes out (your expenses), helping you make more informed decisions. It’s not about “tightening the belt,” but about understanding your habits and making room for your goals.

🛠️ Step-by-step to build your budget

1. List your income
Start by identifying all sources of income: salary, side gigs, rentals, investment returns. Use net values (after taxes).

2. List all your expenses
Classify them into:

  • Fixed (rent, internet, transportation, school)
  • Variable (food, entertainment, delivery, shopping)
  • Often forgotten (gifts, taxes, maintenance)
    Tip: Look at your bank statements from the last 3 months!

3. Create spending categories
Organize your expenses into categories to make analysis easier:

  • Housing
  • Food
  • Transportation
  • Health
  • Entertainment
  • Investments
  • Debt

4. Compare income and expenses
If expenses exceed income: ⚠️ Red Alert. You’ll need to cut costs or increase income.
If you have money left over: time to plan investments!
Check if you're spending more on variables than you're saving.
A good practice before any purchase is to ask: Do I NEED this or do I WANT this?
This helps differentiate between necessary and unnecessary expenses.

🎯 Financial Planning: looking ahead
Planning means turning goals into numbers.
Want to travel, buy a car, get a degree, or ensure a peaceful retirement? It all starts with a plan.

Tips for setting goals:

  • Specific: “I want to save R$5,000 to travel in 10 months”
  • Measurable: How much do you need to save each month?
  • Achievable: Can you fit it in your budget?
  • Relevant: Does it make sense for you?
  • Time-bound: Set deadlines

💡 Practical tips to maintain financial control

  • Use spreadsheets or budgeting apps (Guiabolso, Organizze, Mobills, Minhas Economias)
  • Set a “monthly finance review day”
  • Have a separate account for your goals (trips, home, car)
  • Avoid automatic installment plans as much as possible
  • Build the habit of saving before spending
