Revenue gets all the attention. It's the number founders brag about, the metric investors ask about first, and the figure that makes headlines. But expenses determine whether that revenue turns into profit or vanishes into overhead. And most business owners have only a vague sense of where their money actually goes.
An expense ratio analysis breaks your spending into categories and shows each one as a percentage of revenue. It takes 15 minutes and often reveals surprises that are worth thousands of dollars in annual savings.
The Eight Categories That Matter
Cost of goods sold (COGS) is usually the biggest slice — the direct cost of producing what you sell. For product businesses, this is materials, manufacturing, and fulfillment. For service businesses, it's the labor cost of delivery. The benchmark varies enormously: a restaurant might spend 30-35% on food costs, while a software company might spend 5-10% on hosting and infrastructure.
Payroll is often the second-largest expense. For service businesses, it can be 40-60% of revenue. The key question isn't whether payroll is high — it's whether each dollar of payroll generates enough revenue to justify it. A salesperson costing $80,000 who generates $400,000 in revenue is a bargain. One who generates $100,000 is a problem.
Marketing is where spending discipline matters most. The general benchmark is 5-15% of revenue, but this varies by stage. Early-stage businesses investing in growth might spend 20-30%. Established businesses with strong organic traffic might spend 5%. The question is whether each marketing dollar produces a measurable return.
Rent, software, insurance, and travel round out the picture. Each one individually might seem small, but together they can easily consume 15-25% of revenue. Software subscriptions are particularly insidious — they accumulate gradually ($29 here, $49 there, $99 for that tool you used twice) until the monthly total is eye-opening.
What Healthy Ratios Look Like
A business spending 90% of revenue on expenses has a 10% profit margin — viable but thin. One spending 70% has a 30% margin — healthy and resilient. The goal isn't to minimize every category to zero; it's to ensure each dollar of spending is pulling its weight.
If your biggest expense category is significantly above industry benchmarks, that's where optimization effort should focus. A 5% reduction in your largest expense category will have more impact than a 20% reduction in your smallest one. Prioritize the big slices.
