What Are Financial Ratios?
Definition
- Numerical calculations to evaluate financial strength and progress
- Tools/yardsticks for developing saving, spending, and credit-use patterns
- Simplify evaluation of financial condition
Purpose
- Assess financial health
- Track progress toward goals
- Identify areas needing improvement
- Compare against recommended benchmarks
Four Key Financial Ratios
1. Basic Liquidity Ratio
Purpose
“Can I pay for emergencies?”
Definition
- Measures number of months you can meet expenses using only liquid assets if income ceases
- Tests emergency preparedness
Formula
Basic Liquidity Ratio = Liquid Assets / Monthly Expenses
Benchmark
- Recommended: 3 or higher
- Means: 3 months of expenses in emergency cash reserves
Interpretation
- Higher is better
- Ratio of 3 = Can survive 3 months without income
- Ratio < 3 = Need more emergency savings
- Ratio > 3 = Strong emergency fund
Example
- Liquid assets: $9,000
- Monthly expenses: $3,000
- Ratio: $9,000 / $3,000 = 3.0 ✓ (Meets recommendation)
2. Asset-to-Debt Ratio
Purpose
“Do I have enough assets compared with liabilities?”
Definition
- Compares total assets with total liabilities
- Measures solvency and ability to pay debts
Formula
Asset-to-Debt Ratio = Total Assets / Total Liabilities
Benchmark
- Recommended: Greater than 1
- Must be > 1 to be solvent
Interpretation
- Higher is better
- Ratio > 1 = Solvent (own more than you owe)
- Ratio = 1 = Break even
- Ratio < 1 = Insolvent (owe more than you own)
Example 1: Solvent
- Total assets: $50,000
- Total liabilities: $30,000
- Ratio: $50,000 / $30,000 = 1.67 ✓ (Solvent)
Example 2: Insolvent (College Student)
- Total assets: $7,960
- Total liabilities: $8,700
- Ratio: $7,960 / $8,700 = 0.915 ✗ (Insolvent)
Note: Negative net worth is common for college students
3. Debt Service-to-Income Ratio
Purpose
“Can I meet my total debt obligations?”
Definition
- Compares dollars spent on gross annual debt repayments with gross annual income
- Shows total debt burden
- Includes rent or mortgage payments
Formula
Debt Service-to-Income Ratio = Annual Debt Payments / Gross Annual Income
Benchmark
- Recommended: 1/3 (0.333) or less
- Maximum: 36% of gross income
Interpretation
- Lower is better
- Ratio ≤ 0.333 = Manageable debt
- Ratio > 0.333 = Too much debt, difficulty meeting obligations
- Usually decreases with age (car paid off, house paid off)
Example 1: Good
- Annual debt payments: $18,000
- Gross annual income: $60,000
- Ratio: $18,000 / $60,000 = 0.30 ✓ (Good)
Example 2: Too High
- Annual debt payments: $25,000
- Gross annual income: $60,000
- Ratio: $25,000 / $60,000 = 0.417 ✗ (Too high)
4. Investment Assets-to-Total Assets Ratio
Purpose
“Do I need to invest more?”
Definition
- Compares value of investment assets with total assets
- Reveals progress toward capital accumulation goals
- Especially important for retirement planning
Formula
Investment Assets-to-Total Assets Ratio = Investment Assets / Total Assets
Benchmark (Age-Based)
- 20s: 10% appropriate
- 30s: 11-30% appropriate
- 40s: Above 30%
- 50s+: 50% or higher desirable
Interpretation
- Higher is better (for building wealth)
- Shows how much of wealth is working for you
- Low ratio = Too much in non-productive assets
Example 1: Age 25
- Investment assets: $5,000
- Total assets: $40,000
- Ratio: $5,000 / $40,000 = 0.125 (12.5%) ✓ (Good for 20s)
Example 2: Age 45
- Investment assets: $80,000
- Total assets: $200,000
- Ratio: $80,000 / $200,000 = 0.40 (40%) ✓ (Good for 40s)
Summary Table
| Ratio | Formula | Benchmark | Goal |
|---|---|---|---|
| Basic Liquidity | Liquid Assets / Monthly Expenses | ≥ 3 | Higher is better |
| Asset-to-Debt | Total Assets / Total Liabilities | > 1 | Higher is better |
| Debt Service-to-Income | Annual Debt Payments / Gross Income | ≤ 0.333 | Lower is better |
| Investment Assets-to-Total Assets | Investment Assets / Total Assets | Age-dependent | Higher is better |
How to Use Financial Ratios
Step 1: Calculate Current Ratios
- Use your balance sheet and cash-flow statement
- Calculate all four ratios
Step 2: Compare to Benchmarks
- Identify which ratios meet recommendations
- Identify which need improvement
Step 3: Develop Action Plan
- Low liquidity? Build emergency fund
- High debt-to-income? Pay down debt
- Low investment ratio? Increase investing
- Asset-to-debt < 1? Increase assets or pay off debt
Step 4: Track Progress
- Recalculate ratios quarterly or annually
- Monitor improvement over time
- Adjust strategies as needed
Practical Examples
Example: Complete Ratio Analysis
Given:
- Liquid assets: $6,000
- Total assets: $45,000
- Total liabilities: $25,000
- Investment assets: $8,000
- Monthly expenses: $2,500
- Annual debt payments: $15,000
- Gross annual income: $50,000
Calculate:
- Basic Liquidity Ratio
$6,000 / $2,500 = 2.4Status: Below 3, need more emergency savings
- Asset-to-Debt Ratio
$45,000 / $25,000 = 1.8Status: Above 1, solvent ✓
- Debt Service-to-Income Ratio
$15,000 / $50,000 = 0.30Status: Below 0.333, manageable ✓
- Investment Assets-to-Total Assets (assume age 35)
$8,000 / $45,000 = 0.178 (17.8%)Status: Within 11-30% range for 30s ✓
Action Plan:
- Priority: Increase emergency fund from 2.4 to 3 months
- Need: $2,500 × 3 = $7,500 (need $1,500 more)

Practice Problems
Problem 1
Given:
- Liquid assets: $12,000
- Monthly expenses: $3,000
Calculate: Basic liquidity ratio
Solution: $12,000 / $3,000 = 4.0 (Excellent!)
Problem 2
Given:
- Total assets: $100,000
- Total liabilities: $80,000
Calculate: Asset-to-debt ratio. Is person solvent?
Solution: $100,000 / $80,000 = 1.25 (Yes, solvent)
Problem 3
Given:
- Annual debt payments: $20,000
- Gross annual income: $70,000
Calculate: Debt service-to-income ratio. Is it acceptable?
Solution: $20,000 / $70,000 = 0.286 (Yes, below 0.333)
Problem 4
Given:
- Investment assets: $30,000
- Total assets: $120,000
- Age: 42
Calculate: Investment assets-to-total assets ratio. Is it appropriate?
Solution: $30,000 / $120,000 = 0.25 (25%) (Borderline for 40s, should aim for 30%+)
