Investment Portfolio Allocation
The "100 minus age" rule suggests your stock percentage should equal 100 minus your age. At 30 years old, consider 70% stocks and 30% bonds for optimal growth vs. stability balance.
Emergency Fund Target
Financial experts recommend saving 20% of your income, with 10% for retirement and 10% for emergency funds. A $60,000 salary should generate $12,000 annual savings ($1,000 monthly).
Debt-to-Income Ratio
Keep total debt payments below 36% of gross income for financial stability. On $5,000 monthly income, maximum debt payments should be $1,800 including mortgage, car, and credit cards.
Business Profit Margins
Healthy profit margins vary by industry: Software (70-85%), Restaurants (3-10%), Retail (2-6%). Calculate your margins regularly to ensure business sustainability.
