Frequently Asked Questions
What is the Operating Expense Ratio (OER)?
The Operating Expense Ratio measures what percentage of your revenue is consumed by operating expenses. It's calculated as Operating Expenses ÷ Revenue × 100. For example, if a Mississauga retail business has $450,000 in operating expenses and $1,200,000 in revenue, the OER is 37.5%. This metric helps Ontario business owners understand operational efficiency and cost control effectiveness.
What is a good Operating Expense Ratio for Canadian businesses?
A "good" OER varies by industry. In the GTA, professional services firms typically aim for 60-75%, while retail businesses target 20-35%, and SaaS companies may run 70-85% in growth phases. Lower ratios generally indicate better operational efficiency, but context matters. Our CPAs in Toronto help businesses benchmark against industry standards and identify optimization opportunities specific to Ontario's business environment.
How can I reduce my Operating Expense Ratio?
Ontario businesses can reduce OER through: (1) Negotiating better supplier contracts, (2) Automating repetitive processes, (3) Optimizing staffing levels, (4) Reducing unnecessary subscriptions/services, (5) Improving energy efficiency, and (6) Strategic outsourcing. Mississauga CPAs at Insight Accounting analyze your expense structure and identify tax-efficient cost reduction strategies that don't compromise growth or quality.
Should Cost of Goods Sold (COGS) be included in OER?
No. Operating Expense Ratio typically excludes Cost of Goods Sold (COGS), interest, taxes, depreciation, and amortization. It focuses on operational costs like rent, utilities, salaries (non-production), marketing, insurance, and office supplies. For Toronto-area businesses, proper classification of expenses is critical for accurate financial analysis and CRA compliance. Our accounting team ensures your financial statements categorize expenses correctly.
How does OER relate to profitability?
A lower Operating Expense Ratio leaves more revenue available for profit after covering operating costs. However, OER alone doesn't show profitability — you must also consider COGS and other expenses. For GTA businesses, Insight Accounting analyzes OER alongside gross margin, net profit margin, and cash flow to provide a complete profitability picture and recommend strategies to improve bottom-line results while maintaining compliance with Canadian tax regulations.
