What this calculator means
Business Expense Ratio: Expense ratios measure how much of each revenue dollar goes to specific cost categories. Tracking rent/revenue, labor/revenue, and marketing/revenue ratios helps small business owners identify cost problems before they threaten profitability.
Formula and example
Each ratio = Category Cost ÷ Revenue × 100. Health score graded against benchmarks: rent < 10% = good, 10-15% = watch, > 15% = high.
$20K revenue, 10% rent, 35% labor, 7.5% marketing, 25% COGS = 77.5% total expenses, 22.5% operating margin. Health score: labor slightly high (benchmark 20-30%), other metrics healthy.

Methodology & assumptions
Last updated: 2026-06-19Calculation method
Calculates key operating expense ratios and compares against small business benchmarks. Benchmarks: Rent 5-10% (service) / 8-15% (retail); Labor 20-30% (service-heavy) / 30-40% (labor-intensive); Marketing 5-12% (established) / 10-20% (growth); COGS 20-50% (product) / 0-15% (service). Health score combines all ratios into a 0-100 grade.
Data sources
Uses the numbers you enter and standard small-business finance formulas. Benchmark comparisons use HustleFin industry benchmark pages where available.
Limitations
Benchmarks are general guidelines based on US small business data. Your industry, business model, and growth stage may justify ratios outside these ranges. Startups typically have higher marketing ratios; mature businesses should trend toward lower overhead. Not a substitute for CPA review.

Frequently asked questions
What is a good rent-to-revenue ratio?+
For most small businesses, 5-10% of revenue spent on rent is healthy. Service-based businesses (consulting, agencies) trend toward 3-7%. Retail and restaurants trend 8-15%. Over 15% is a red flag — you're likely location-heavy and should negotiate rent or consider downsizing.
How much should I spend on marketing as a small business?+
5-12% of revenue is typical for established businesses. Growth-stage companies may spend 12-20%. Early-stage startups might allocate 20-50% temporarily to build awareness. Track customer acquisition cost (CAC) alongside marketing spend to ensure you're getting returns, not just spending.
What is the difference between COGS ratio and operating expense ratio?+
COGS ratio (COGS ÷ Revenue) measures direct production costs — materials, direct labor, production overhead. Operating expense ratio (OpEx ÷ Revenue) covers indirect costs like rent, marketing, admin salaries. The sum of both ratios is your total expense ratio; what's left is your operating profit margin.
How do I improve my expense ratios?+
Prioritize the biggest ratio first. If labor is 45% of revenue, it's your biggest lever — either increase revenue per employee or reduce headcount. If rent is 18%, renegotiate or relocate. If marketing is 3% and sales are stagnant, you may be underinvesting. The goal is balance, not minimizing every number to zero.
