Definition of Cost Ratio

The cost ratio is a financial metric that measures the relationship between expenses and revenue, assets, or investments. It helps businesses and investors assess the efficiency of operations, fund management, or investment performance. A lower cost ratio indicates better efficiency, while a higher ratio may suggest excessive expenses.

For example, if a company earns $1 million in revenue but incurs $300,000 in expenses, its cost ratio is 30%, meaning 30% of revenue is used for operational costs.

Purpose of Cost Ratio in Financial Analysis

The cost ratio is used to:

• Evaluate business efficiency by measuring operational costs relative to revenue.
• Analyze investment performance, particularly in mutual funds and ETFs.
• Compare financial health across industries and businesses.
• Identify cost-cutting opportunities to improve profitability.
• Assist investors in decision-making, particularly in fund management.

How to Calculate the Cost Ratio

Cost Ratio Formula

Cost Ratio = Total Expenses / Total Revenue × 100

Example Calculation

• A business has $400,000 in total expenses and $1.2 million in total revenue.
• Calculation:
  400,000 / 1,200,000 × 100 = 33.3%
• Interpretation: The business spends 33.3% of its revenue on expenses, indicating its operational efficiency.
