Thriving Health & Wealth during Lifetime

🏡 Household Cash-Flow Formula

Net Cash-Flow = Total Income – Total Expenses

To make it actionable, break it into 4 main building blocks:


1. Income (Cash-In)

  • 💼 Active Income: Salaries, wages, freelance, business income
  • 💰 Passive Income: Interest, dividends, rental income
  • 🎁 Other Income: Transfers, pensions, subsidies, tax refunds

Total Income = Active + Passive + Other


2. Fixed Expenses (Cash-Out – Mandatory)

  • 🏠 Housing: Rent/mortgage, utilities
  • 🚗 Transportation: Fuel, insurance, public transport
  • 🍽️ Essentials: Food, health insurance, medicine
  • 🎓 Education & Childcare

3. Variable Expenses (Cash-Out – Flexible)

  • 🛍️ Lifestyle: Clothing, entertainment, restaurants
  • 🌍 Travel: Holidays, short trips
  • 📱 Subscriptions: Streaming, apps, memberships

4. Savings & Investments

  • 📈 Emergency Fund (3–6 months of expenses)
  • 💵 Debt Repayment (if applicable)
  • 🏦 Long-Term Investments: ETFs, bonds, retirement plans
  • 🎯 Short-Term Goals: Car, house renovation, studies

📊 Formula in Practice

Net Cash-Flow=(Active + Passive + Other Income)  −  (Fixed + Variable Expenses)  −  (Savings + Investments)

  • Positive Net Cash-Flow → Wealth builds, financial freedom grows
  • Negative Net Cash-Flow → Debt risk, lifestyle needs adjustment

✅ Action Steps

  1. Track every cash-in and cash-out monthly (Excel, app, or notebook).
  2. Apply the 50–30–20 rule as a guide:
    • 50% Needs (fixed expenses)
    • 30% Wants (variable expenses)
    • 20% Savings/Investments
  3. Aim for a positive monthly surplus and direct it to savings & investments.
  4. Review quarterly: cut waste, increase passive income.
