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