💰 Personal Finance

Why Personal Finance Matters

Personal finance is the management of your money over time.

It links:

• Income ➜ what you earn
• Spending ➜ what you use now
• Saving & Investing ➜ what you keep for later
• Risk Management ➜ protection from loss

> Goal: align money decisions with your values and long‑term objectives.

Key Financial Goals

Typical advanced goals:

• Build a 3–6 month emergency fund
• Eliminate high-interest debt
• Save 15–20% of income for retirement
• Plan for education, housing, and healthcare

Each goal trades off current lifestyle versus future security.

Key idea: You cannot optimize everything; you prioritize.

The Personal Balance Sheet

Think of yourself like a small firm.

• Assets: cash, investments, home equity, skills
• Liabilities: debts, obligations
• Net worth = Assets − Liabilities

Rising net worth usually signals financial health, even if income is modest.

Tracking it yearly reveals your financial trajectory.

The Personal Income Statement

Over a period (month or year):

• Income: salary, benefits, side hustles
• Expenses: fixed, variable, discretionary

Savings = Income − Expenses

Savings is your “profit”. A positive, growing surplus funds investing, debt payoff, and flexibility.

The Time Value of Money⏳

A dollar today is worth more than a dollar tomorrow because it can earn returns.

Core idea:

• Earlier cash flows ➜ more valuable
• Later cash flows ➜ discounted back

This underpins decisions about loans, pensions, and investments.
