Personal Finance Fundamentals Everyone Should Know
Financial literacy is a superpower. Here are the fundamentals everyone needs.
The Money Mindset
Before tactics, understand these principles:
- Spend less than you earn - The foundation of all finance
- Time is money - Compound interest rewards patience
- Risk and reward - Higher returns require higher risk
- Education pays - Financial knowledge compounds
The Budget Foundation
50/30/20 Rule
| Category | Percentage | Examples |
|---|---|---|
| Needs | 50% | Housing, food, utilities |
| Wants | 30% | Entertainment, hobbies |
| Savings | 20% | Investments, emergency fund |
Adjust based on your life stage and income.
Building an Emergency Fund
Your safety net:
- Start with $1,000 for minor emergencies

Good vs Bad Debt
