Business Expense Ratio Calculator

A business expense ratio (also called the operating expense ratio) measures your total operating expenses as a percentage of revenue. It shows how much of each rand earned is consumed by expenses. A lower ratio generally indicates a more efficient business, though the ideal ratio varies significantly by industry.

There is no single "good" ratio as it varies by industry. Service businesses often have ratios of 60-80%, retail businesses 75-90%, and technology companies 50-70%. The key is to benchmark against your industry peers and track your ratio over time to identify trends and areas for improvement.

Operating margin is calculated as (Revenue - Total Operating Expenses) / Revenue x 100. It represents the percentage of revenue that remains after covering all operating costs. A positive operating margin means the business is profitable at the operational level, before accounting for taxes and non-operating items.

Key categories include rent and utilities, salaries and wages, marketing and advertising, administrative and office expenses, professional services (accounting, legal), insurance, and a catch-all for other expenses. Breaking expenses into these categories helps identify which areas consume the most resources and where savings may be possible.

Focus on the largest expense categories first for maximum impact. Common strategies include renegotiating supplier contracts, reducing office space costs with hybrid work, automating repetitive tasks, reviewing subscription services, and improving marketing ROI. Always ensure cost-cutting does not compromise the quality of your product or service.
