The Financial Formulas

Net worth = Assets − Liabilities. 50/30/20 rule: 50% needs, 30% wants, 20% savings. At 3% inflation, $100K today is worth $74K in 10 years. A 6% return with 4% inflation = only 2% real return.

Personal Finance Examples

Everyday financial decisions:

50/30/20 budget

$5K/month: $2,500 needs, $1,500 wants, $1,000 savings.

Emergency fund

$4,500/month expenses = $13.5K–$27K target (3–6 months).

Savings goal

$500/month at 4.5% APY reaches $20K in 36 months.

Inflation reality check

$100K at 3% inflation loses $25.6K purchasing power over 10 years.

Smart Money Management Tips

Proven strategies for financial security:

Automate savings

Auto-transfer on payday. Aim for 20% of take-home pay.

Build emergency fund first

3–6 months expenses in a high-yield savings account.

Track net worth annually

A growing net worth confirms your plan is working.

Adjust the 50/30/20 rule

In high-cost areas, needs may take 60%. Adjust to fit.

Pay yourself first

Treat savings as non-negotiable — transfer before spending.

Financial Mistakes to Avoid

Common pitfalls that derail progress:

Not tracking spending

Track every dollar for 30 days — most underestimate by 20%.

Emergency fund in checking

Move to a separate high-yield savings account.

Ignoring inflation

Cash loses purchasing power yearly — invest for long-term goals.

Lifestyle inflation

Keep expenses flat when income rises — save the difference.

No financial goals

Set specific targets like "$20K emergency fund by December."
