How to Use This Calculator
Benchmark your startup's operating expenses in three steps.
Select Your Stage
Choose your funding stage from Pre-seed through Series B+. Each stage has different benchmark ranges reflecting typical spend patterns.
Enter Your Expenses
Input your total monthly OpEx and break it down across six categories: payroll, engineering, sales, G&A, tools, and infrastructure.
Compare & Adjust
See a side-by-side comparison with color-coded status indicators and personalized observations on where to optimize spending.
How OpEx Benchmarks Work
The calculator compares each category as a percentage of total monthly OpEx against stage-specific ranges drawn from industry data.
Formula
Each category percentage is compared against the benchmark range for your stage. If the percentage falls within the range, it is marked green. Values slightly outside the range (within 10 percentage points) are marked yellow. Values more than 10 points outside are marked red.
Example: Seed-Stage Startup at $50K/mo
| Category | Amount | Your % | Benchmark |
|---|---|---|---|
| Payroll | $32,000 | 64% | 60-70% |
| Engineering | $18,000 | 36% | 30-40% |
| Sales & Marketing | $5,000 | 10% | 10-15% |
| G&A | $3,500 | 7% | 5-10% |
| Tools | $3,000 | 6% | 5-8% |
| Infrastructure | $3,000 | 6% | 5-8% |
All categories fall within seed-stage benchmarks. This $50K monthly OpEx is well-allocated for a seed startup focused on product development.
Frequently Asked Questions
Common questions about startup operating expense benchmarks.
What are typical startup operating expenses?+
Typical startup operating expenses break down into six main categories. Payroll and benefits consume 50-70% of total OpEx across all stages and represent the single largest line item. Engineering and R&D range from 20-45% depending on whether you are pre-revenue or scaling. Sales and marketing starts at 5-10% for pre-seed and rises to 20-30% by Series B+ as you invest in growth. General and administrative costs stay at 5-15%, software and tools at 3-8%, and infrastructure or hosting at 3-10%. For a deeper breakdown by stage, see our guide on operating expense benchmarks for startups.
How much should a startup spend on marketing?+
Marketing spend depends on your stage and product-market fit. Pre-seed startups should keep marketing at 5-10% of OpEx since you are still validating your product. At seed stage, 10-15% is typical as you begin targeted acquisition. Series A companies often allocate 15-25% to scale proven channels, while Series B+ companies push to 20-30% for aggressive growth. The key signal for increasing marketing spend is strong retention data. If your churn rate is high, spending more on marketing just accelerates losses. Use our burn rate calculator to see how marketing spend affects your runway.
When should G&A spending increase?+
G&A spending naturally increases as startups mature. At pre-seed and seed stage, 5-10% of OpEx is normal since founders handle most admin tasks. By Series A, 8-12% is typical as you hire dedicated finance, HR, and legal roles. Series B+ companies allocate 10-15% as compliance, reporting, and operational complexity scale. If your G&A exceeds these benchmarks at an early stage, audit for overhead that can be automated. Tools like profitability calculators help you understand the impact of G&A on your bottom line.
Why OpEx Benchmarks Matter for Startups
Operating expenses are the clearest signal of how a startup allocates its limited capital. Yet most founders budget by feel rather than data. This calculator gives you a structured way to compare your spend against companies at the same stage, so you can spot misallocations before they drain your runway.
The most common mistake is under-investing in sales and marketing while over-indexing on engineering. Pre-seed teams rightly focus on building, but seed and Series A companies that keep marketing below 10% of OpEx often struggle to generate the growth data investors need for the next round. Our operating expense benchmarks guide breaks down why the shift from build-mode to growth-mode spending is critical at each stage.
Software and tools spending is another area that quietly balloons. At pre-seed, founders sign up for every tool with a free tier. By seed stage, those subscriptions stack up. Our analysis in pre-seed software budget planning shows that teams spending more than 8% of OpEx on tools typically have redundant subscriptions or unused seats that can be cut immediately.
Payroll is always the largest line item, but the ratio tells you different things at different stages. A pre-seed company at 65% payroll with three engineers is healthy. A Series A company at 70% payroll may have hired too fast. Use the employee cost calculator to understand the true burden of each hire, and the burn rate calculator to see how headcount changes ripple through your runway.
For a complete view of whether your spending is sustainable, pair this benchmark analysis with the profitability calculator to see how long until your revenue covers these operating costs. The goal is not to minimize every category but to allocate deliberately based on your stage and strategy.
