Income Ratios
Income ratios measure the relationship between your income and other financial metrics. They provide insight into your financial stability and efficiency. Understanding these ratios can help you make informed decisions about budgeting, saving, and investing.

Examples of Income Ratios:

1. Gross Income Ratio:
- Formula: Gross Income = Total Income before Taxes and Deductions
- Description: This ratio indicates your total earnings from all sources before any taxes or deductions are applied. It helps you understand your overall earning capacity and can be used to compare with other income-related ratios.

2. Net Income Ratio:
- **Formula:** Net Income = Total Income after Taxes and Deductions
- **Description:** This ratio shows your income after all taxes and deductions have been accounted for. It represents the actual amount available for spending, saving, and investing.

3. Savings Rate:
- Formula: Savings Rate = (Total Savings / Total Income) x 100
- Description: This ratio indicates the percentage of your income that you save. A higher savings rate is generally better, as it means you are setting aside more money for future needs and investments.

4. Disposable Income Ratio:
- Formula: Disposable Income = Net Income - Essential Living Expenses
- Description: This ratio represents the amount of income left after covering essential living expenses. It helps in understanding how much money is available for discretionary spending, saving, or investing.

Age Benchmarks:
- 20-30 years: Focus on building savings and reducing debt.

Debt Ratios

Debt ratios measure the extent of your debt relative to your income and assets. These ratios help you understand your debt burden and repayment capacity, which are crucial for maintaining financial health and avoiding over-leverage.

Examples of Debt Ratios:

1. Debt-to-Income Ratio (DTI):
- Formula: DTI = (Total Monthly Debt Payments / Gross Monthly Income) x 100
- Description: This ratio indicates the percentage of your income that goes toward debt payments. A lower DTI ratio is preferable, as it suggests a manageable debt load and higher financial flexibility.

2. Debt-to-Asset Ratio:
- Formula: Debt-to-Asset Ratio = (Total Debt / Total Assets) x 100
- Description: This ratio measures the proportion of your assets financed by debt. A lower ratio indicates a healthier balance between debt and assets, reducing the risk of financial instability.

3. Debt Service Coverage Ratio (DSCR):
- Formula: DSCR = (Net Operating Income / Total Debt Service)
- Description: This ratio is used to assess an individual's or business's ability to generate enough income to cover debt obligations. A higher DSCR indicates a better ability to service debt.

4. Interest Coverage Ratio:
- Formula: Interest Coverage Ratio = (Earnings Before Interest and Taxes (EBIT) / Interest Expenses)
- Description: This ratio measures the ability to pay interest on outstanding debt with earnings. A higher ratio signifies greater ease in meeting interest payments.

Age Benchmarks:

- 20-30 years: Aim to keep DTI below 35%.
- 30-40 years: Focus on reducing high-interest debt.

Investment Ratios
Investment ratios evaluate the performance and allocation of your investments, providing insight into your investment strategy and risk exposure. These ratios help in assessing the efficiency and profitability of your investments.

Examples of Investment Ratios:

1. Return on Investment (ROI):
- Formula: ROI = (Net Profit / Cost of Investment) x 100
- Description: This ratio measures the profitability of an investment. A higher ROI indicates better investment performance, reflecting the effectiveness of your investment strategy.

2. Investment-to-Savings Ratio:
- Formula: Investment-to-Savings Ratio = (Total Investments / Total Savings)
- Description: This ratio shows the proportion of your savings that are invested. A higher ratio suggests a proactive approach to growing wealth through investments.

3. Price-to-Earnings Ratio (P/E):
- Formula: P/E = (Market Price per Share / Earnings per Share)
- Description: This ratio evaluates the value of a company's stock, comparing the market price to its earnings. A lower P/E ratio may indicate an undervalued stock, while a higher ratio could suggest overvaluation.

4. Dividend Yield:
- Formula: Dividend Yield = (Annual Dividends per Share / Market Price per Share) x 100
- Description: This ratio measures the return on investment from dividends. A higher dividend yield indicates a higher return from dividends relative to the stock price.

Age Benchmarks:
- 20-30 years: Focus on growth investments with higher ROI.
- 30-40 years: Diversify investments to balance risk and return.
- 40-50 years: Increase allocation to stable, income-generating investments.

Liquidity Ratios:
Liquidity ratios assess your ability to meet short-term financial obligations, indicating the availability of liquid assets to cover expenses. These ratios are crucial for ensuring financial stability and flexibility.

Examples of Liquidity Ratios:

1. Current Ratio:
- Formula: Current Ratio = (Current Assets / Current Liabilities)
- Description: This ratio measures your ability to pay short-term obligations with your current assets. A higher ratio indicates better liquidity and financial health.

2. Quick Ratio (Acid-Test Ratio):
- Formula: Quick Ratio = (Current Assets - Inventory) / Current Liabilities
- Description: This ratio provides a more stringent measure of liquidity by excluding inventory from current assets. A higher quick ratio indicates a stronger ability to meet short-term liabilities without relying on the sale of inventory.

3. Emergency Fund Ratio:
- Formula: Emergency Fund Ratio = (Liquid Assets / Monthly Expenses)
- Description: This ratio indicates how many months you can cover your expenses with your liquid assets. A higher ratio suggests better preparedness for emergencies and unexpected financial setbacks.

4. Cash Ratio:
- Formula: Cash Ratio = (Cash and Cash Equivalents / Current Liabilities)
- Description: This ratio measures the proportion of cash and cash equivalents available to cover current liabilities. A higher cash ratio indicates better immediate liquidity.

Age Benchmarks:
- 20-30 years: Aim for an emergency fund covering 3-6 months of expenses.
