How to Calculate Expense Ratios

Key Formulas

Total Expense Ratio: (Total Expenses ÷ Revenue) × 100
Total Expenses = COGS + Operating Expenses
Operating Expense Ratio (OER): (Operating Expenses ÷ Revenue) × 100
Operating Expenses = Labor + Rent + Marketing + Admin + Other
Gross Profit Margin: ((Revenue - COGS) ÷ Revenue) × 100
Higher is better; shows product profitability
Net Profit Margin: ((Revenue - Total Expenses) ÷ Revenue) × 100
Bottom line profitability after all costs

Calculation Steps:

  1. 1
    Calculate total revenue
    All sales and income for the period
  2. 2
    Sum all expense categories
    COGS, labor, rent, marketing, admin, and other
  3. 3
    Divide expenses by revenue
    Creates decimal ratio (e.g., 0.75)
  4. 4
    Multiply by 100 for percentage
    Converts to familiar format (e.g., 75%)

Example Cases

Case 1: Small Consulting Firm

Revenue: $100,000
COGS: $40,000
Labor: $25,000
Rent: $8,000
Marketing: $5,000
Admin: $4,000
Other: $3,000
Total Expense Ratio: 85%
Operating Expense Ratio: 45%
Gross Profit Margin: 60%
Net Profit Margin: 15%
Net Profit: $15,000
Classification: Average

Analysis: This consulting firm has high gross margins (60%) typical of service businesses, but operating expenses are consuming 45% of revenue. Opportunities exist to reduce overhead costs while maintaining service quality.

Case 2: E-commerce Retailer

Revenue: $500,000
COGS: $300,000
Labor: $50,000
Rent: $20,000
Marketing: $40,000
Admin: $15,000
Other: $10,000
Total Expense Ratio: 87%
Operating Expense Ratio: 27%
Gross Profit Margin: 40%
Net Profit Margin: 13%
Classification: Average

Analysis: Typical e-commerce margins with 60% product costs. Marketing expenses at 8% of revenue are reasonable for customer acquisition. Operating efficiency is good at 27%, but COGS optimization (supplier negotiation, inventory management) could significantly improve profitability.

Cost Control Strategies

1

Negotiate Supplier Terms

Reduce COGS through volume discounts, longer payment terms, or alternative suppliers. Even 2-3% improvement in COGS can significantly boost profit margins. Build strong supplier relationships and leverage competition for better pricing.

2

Optimize Labor Efficiency

Analyze productivity per employee, automate routine tasks, and use data-driven scheduling. Consider contractors for variable workload. Cross-train staff for flexibility. Labor is often 20-40% of expenses—small gains create major impact.

3

Improve Marketing ROI

Track marketing spend by channel and eliminate low-performing campaigns. Focus on high-conversion channels. Use analytics to optimize customer acquisition cost (CAC). Better targeting beats bigger budgets—efficiency over volume.

4

Streamline Operations

Implement process improvements, eliminate redundant tasks, and leverage technology. Cloud services, automation tools, and integrated systems reduce administrative burden. Map workflows to identify bottlenecks and waste.

5

Revenue Growth Strategy

Increasing revenue lowers expense ratio even with constant costs. Focus on pricing optimization, upselling existing customers, expanding market reach, and improving customer retention. Fixed costs spread across more revenue improve margins naturally.

Frequently Asked Questions

What is an expense ratio?
An expense ratio is a financial metric that measures the percentage of revenue consumed by expenses. It is calculated as Total Expenses ÷ Total Revenue × 100. A lower expense ratio indicates better operational efficiency and higher profitability. For example, a 75% expense ratio means $0.75 of every dollar earned is spent on costs.
What is a good expense ratio for a business?
A "good" expense ratio varies by industry. Generally, ratios below 60% are excellent, 60-75% are good, 75-85% are average, and above 85% may indicate inefficiency. Service businesses often have lower ratios (50-70%) due to minimal COGS, while retail typically ranges 75-85%. Manufacturing may see 70-80% ratios depending on automation and scale.
How is operating expense ratio different from total expense ratio?
Operating Expense Ratio (OER) only includes operating costs (labor, rent, marketing, admin) divided by revenue, excluding Cost of Goods Sold (COGS). Total Expense Ratio includes both COGS and operating expenses. OER is useful for comparing operational efficiency independent of product costs, which may vary due to market conditions.
How can I reduce my expense ratio?
Key strategies include: 1) Negotiate better supplier terms to reduce COGS, 2) Optimize labor through automation or scheduling, 3) Renegotiate rent or consider relocation, 4) Use data-driven marketing to improve ROI, 5) Streamline administrative processes, 6) Implement cost tracking and regular audits, 7) Increase revenue through pricing optimization or sales growth.
Should I focus on reducing expenses or increasing revenue?
Both approaches improve your expense ratio, but the best strategy depends on your situation. Reducing expenses provides immediate impact and is easier to control, but has limits. Increasing revenue creates long-term growth and allows economies of scale, but takes time. Most successful businesses pursue both: cut inefficiencies while investing in growth initiatives that generate positive ROI.
