10 Expense Categories Every Startup Should Track
Payroll eats 65-75% of startup burn. Track these 10 expense categories to spot waste, benchmark against peers, and give investors the detail they expect.
Payroll consumes 65-75% of the average seed-stage startup's burn rate. Cloud infrastructure takes 8-12%. Marketing takes 5-10%. But if you are tracking everything in a single "expenses" spreadsheet row, you cannot see where the money goes, spot overspending, benchmark against peers, or give investors the financial detail they expect. The 10 expense categories below cover 95%+ of startup spending and provide the granularity you need without over-engineering your chart of accounts.
Most founders either track too few categories (everything is "operating expenses") or too many (47 sub-categories that no one reviews). The sweet spot for a startup with $80K-$300K/month burn is 10 primary categories with 2-4 sub-categories each. This guide defines each category, provides benchmarks, and explains what to watch for.
Category 1: Payroll and Benefits
This is your largest expense by far. Track these sub-categories separately:
| Sub-Category | Includes | Benchmark (% of Total Burn) |
|---|---|---|
| Salaries | Base pay for full-time employees | 50-60% |
| Benefits | Health insurance, dental, vision, 401k match | 8-12% of salaries |
| Payroll taxes | FICA, FUTA, state unemployment | 7.65-10% of salaries |
| Stock-based compensation | Option grants (non-cash but track for reporting) | N/A (non-cash) |
What to watch: Payroll as a percentage of revenue. Pre-revenue startups are 100%+ (all expense, no revenue). At $100K MRR, payroll should be dropping below 80% of total expenses as revenue starts covering costs. If payroll costs accelerate faster than revenue, you are hiring ahead of traction.
Benchmark by stage:
| Stage | Median Monthly Payroll | Team Size | Payroll/Total Burn |
|---|---|---|---|
| Pre-seed | $20,000-$40,000 | 2-4 | 65-70% |
| Seed | $55,000-$100,000 | 5-12 | 65-75% |
| Series A | $150,000-$300,000 | 15-40 | 60-70% |
Category 2: Cloud Infrastructure
Every SaaS startup's second-largest variable cost. Track by provider and service type.
| Sub-Category | Includes | Benchmark |
|---|---|---|
| Compute (EC2, GCE) | Servers, containers, serverless | 40-50% of cloud spend |
| Storage (S3, Cloud Storage) | Database hosting, file storage, backups | 20-25% |
| Network (CDN, bandwidth) | Data transfer, load balancers, DNS | 10-15% |
| Managed services | RDS, ElastiCache, Pub/Sub, search | 15-25% |
What to watch: Cloud spend as a percentage of revenue (cloud cost ratio). The benchmark for SaaS companies:
| Revenue Stage | Cloud Cost Ratio | Monthly Cloud Spend |
|---|---|---|
| Pre-revenue | N/A | $500-$3,000 |
| $10K-$50K MRR | 15-25% | $1,500-$12,500 |
| $50K-$200K MRR | 10-18% | $5,000-$36,000 |
| $200K+ MRR | 8-15% | $16,000-$30,000+ |
If your cloud cost ratio exceeds 25% of revenue, you likely have optimization opportunities. Run the expense optimization assessment to identify specific areas for cost reduction.
Category 3: Software and Tools
SaaS subscriptions for running the business. This category creeps up silently.
| Sub-Category | Examples | Typical Monthly Cost |
|---|---|---|
| Development tools | GitHub, Jira, Figma, Sentry | $500-$2,000 |
| Sales/marketing tools | HubSpot, Mailchimp, Semrush | $500-$3,000 |
| Communication | Slack, Zoom, Google Workspace | $200-$1,000 |
| Finance/ops | QuickBooks, Gusto, Brex | $200-$800 |
| Security/compliance | 1Password, Vanta, Snyk | $200-$1,000 |
What to watch: Total SaaS spend per employee. The benchmark is $200-$400/employee/month for early-stage startups. A 15-person company spending $8,000/month on tools ($533/employee) is likely paying for overlapping or unused subscriptions.
The SaaS creep problem: Every quarter, audit your tool stack. Check last-login dates for all seats. If a tool has not been used by assigned users in 30+ days, cancel or downgrade it. The average startup wastes $1,000-$3,000/month on unused SaaS subscriptions.

Category 4: Marketing and Advertising
Paid customer acquisition costs. Keep this separate from the marketing team's payroll (which is in Category 1).
| Sub-Category | Includes | Tracking Method |
|---|---|---|
| Paid search (Google, Bing) | Ad spend only (not agency fees) | By campaign/channel |
| Paid social (LinkedIn, Meta) | Ad spend only | By campaign/channel |
| Content marketing | Freelance writers, design, distribution | By content type |
| SEO | Tools, link building, technical SEO | Monthly total |
| Events/sponsorships | Booth fees, speaking, sponsorship packages | Per event |
What to watch: Customer Acquisition Cost (CAC) by channel. If your blended CAC exceeds 12 months of gross margin from the average customer, your marketing spend is inefficient.
| Channel | Typical CAC (B2B SaaS) | Benchmark |
|---|---|---|
| Organic search (SEO) | $40-$150 | Best long-term channel |
| Content marketing | $50-$200 | Slow to start, compounds |
| Google Ads (branded) | $80-$200 | Low volume, high intent |
| Google Ads (non-branded) | $150-$400 | Scalable but expensive |
| LinkedIn Ads | $200-$500 | Good for enterprise |
| Outbound sales | $300-$800 | Labor-intensive |
Category 5: Professional Services
External expertise you buy on a project or retainer basis.
| Sub-Category | Includes | Typical Monthly Cost |
|---|---|---|
| Legal | Corporate counsel, IP, contracts, compliance | $1,000-$5,000 |
| Accounting/bookkeeping | Monthly close, tax prep, audit support | $500-$3,000 |
| Tax | Federal, state, R&D tax credits | $200-$1,000 (amortized) |
| Consulting | Strategy, technical, industry advisors | $0-$5,000 |
What to watch: Legal spend spikes around fundraising ($15,000-$30,000 per round), M&A, or regulatory changes. Budget for these separately from recurring legal costs.
Category 6: Contractors and Freelancers
Temporary labor that supplements your full-time team.
| Sub-Category | Includes | Typical Monthly Cost |
|---|---|---|
| Engineering contractors | Feature development, bug fixes, DevOps | $5,000-$20,000 |
| Design freelancers | UI/UX, marketing design, brand work | $2,000-$8,000 |
| Content creators | Blog writers, video producers | $1,000-$5,000 |
| Virtual assistants | Admin, data entry, scheduling | $500-$2,000 |
What to watch: Contractor spend as a percentage of payroll. If it exceeds 30%, you may be better off hiring full-time. If it is under 5%, you may be missing opportunities to scale faster without permanent headcount commitments.

Category 7: Office and Facilities
Where your team works. This category has shrunk dramatically with remote work but has not disappeared.
| Sub-Category | Includes | Typical Monthly Cost |
|---|---|---|
| Office lease/coworking | WeWork, dedicated office, shared space | $0-$8,000 |
| Utilities | Internet, electricity (if own office) | $100-$500 |
| Furniture/equipment | Desks, chairs, monitors (amortized) | $200-$500 |
| Remote work stipends | Home office allowance, internet subsidy | $50-$200/employee |
What to watch: Total facilities cost per employee. Remote-first startups spend $100-$300/employee/month (stipends + occasional coworking). Office-based startups spend $500-$1,500/employee/month depending on market.
Category 8: Insurance
Mandatory and recommended coverage for startups.
| Type | Required? | Typical Annual Cost |
|---|---|---|
| General liability | Often required by landlords/clients | $400-$1,500 |
| Workers' compensation | Required in most states | $500-$2,000 |
| D&O insurance | Required by most investors post-seed | $2,000-$10,000 |
| E&O / professional liability | Recommended for SaaS | $1,000-$5,000 |
| Cyber liability | Recommended if handling customer data | $1,000-$5,000 |
What to watch: D&O insurance is often forgotten until fundraising. Investors require it, and getting coverage quickly costs 20-30% more than shopping in advance.
Category 9: Travel and Meals
Often the first category cut during belt-tightening.
| Sub-Category | Includes | Typical Monthly Cost |
|---|---|---|
| Business travel | Flights, hotels for sales meetings/conferences | $500-$5,000 |
| Client entertainment | Meals with prospects/customers | $200-$1,000 |
| Team meals/events | Team lunches, offsite meetings | $200-$1,000 |
| Transportation | Uber/Lyft for business, mileage | $100-$500 |
What to watch: Travel spend per revenue dollar generated. If your sales team spends $5,000/month on travel but closes $20,000/month in new revenue, the 25% travel-to-revenue ratio is acceptable. If travel spend is not tied to measurable outcomes, it is a luxury.
Category 10: Financial Services and Fees
The cost of processing money.
| Sub-Category | Includes | Typical Monthly Cost |
|---|---|---|
| Payment processing (Stripe) | 2.9% + $0.30 per transaction | Varies by volume |
| Banking fees | Wire fees, monthly maintenance, FX | $50-$500 |
| Payroll processing | Gusto, Rippling, ADP fees | $100-$500 |
| Corporate card fees | Annual fees, FX markups | $0-$200 |
What to watch: Payment processing fees as a percentage of revenue. At 2.9%, a company at $200K MRR pays ~$5,800/month in Stripe fees. Negotiating a custom rate at higher volumes (Stripe offers volume discounts starting around $80K/month processing) can save $500-$1,500/month.

FAQ
Do I need sub-categories from day one?
No. Start with the 10 top-level categories. Add sub-categories when a category exceeds 10% of total burn and you need more visibility. For example, "Cloud Infrastructure" is fine as a single line until it hits $10,000+/month, then break it into compute, storage, and network.
How do I categorize expenses that span categories?
Assign to the primary purpose. A flight for a sales meeting is "Travel," not "Marketing." A SaaS tool used only by engineers is "Software & Tools" allocated to Engineering. If an expense genuinely spans two categories, pick one and be consistent. Arbitrary splits (50/50) add complexity without insight.
How often should I review category spending?
Monthly for all categories. Weekly for categories over 10% of burn (payroll, cloud, marketing). In real-time for paid advertising (you want to catch runaway ad spend same-day, not 30 days later).
