Cost of revenue is the direct cost of delivering a product or service to paying customers. For a SaaS company, that usually means cloud hosting, customer support, payment processing fees, onboarding labor, and third-party software tied to service delivery. It is not the same as operating expenses such as sales salaries, ads, or general admin costs. Cost of revenue sits below revenue on the income statement and helps calculate gross profit and gross margin, a core measure of SaaS business health [source: Investopedia].
What Cost of Revenue Means in SaaS
In SaaS financial reporting, cost of revenue answers one blunt question: How expensive is it to keep customers served? Revenue alone can make a company look healthy. Cost of revenue shows whether that revenue is efficient.
A SaaS company with high sales growth can still have weak unit economics if hosting costs, support headcount, or onboarding costs rise too fast. That is why gross margin matters so much. A software company with a 75% to 85% gross margin usually has more room to invest in product, sales, and customer success. A company with a 50% margin has less breathing room.
- Included: cloud infrastructure, data storage, support staff, customer success tied to delivery, payment fees, onboarding labor, support tools, and third-party service costs.
- Usually excluded: sales commissions, paid ads, executive salaries, office rent, finance tools, legal costs, and product research.
- Key output: gross profit and gross margin.
The simple formula is:
Gross Margin = (Revenue – Cost of Revenue) / Revenue × 100
If monthly revenue is $250,000 and cost of revenue is $50,000, gross profit is $200,000. Gross margin is 80%.
Why Cost of Revenue Is Often Messy
The hard part is not the formula. The hard part is classification. Teams often argue over whether customer success belongs in cost of revenue or sales and marketing. The answer depends on the role. If the team handles renewals and expansion, some of that cost may sit in sales. If the team supports product usage and service delivery, it may belong in cost of revenue.
Cloud costs can be messy too. A growing customer base may require more servers, data transfer, logs, and storage. If usage-based costs are not tracked by customer segment, finance teams may know revenue is growing but fail to see which customers are expensive to serve.
Honestly, it feels like many SaaS teams learn this too late. They celebrate MRR growth, then discover that enterprise customers need custom onboarding, heavy support, and extra infrastructure. The revenue looks great. The margin does not.
Baremetrics for SaaS Financial Reporting
Baremetrics is often used by founders and small SaaS teams that want fast subscription reporting without building dashboards from scratch. It connects to billing systems and presents metrics such as MRR, ARR, churn, net revenue retention, customer lifetime value, and average revenue per user.
Its biggest strength is speed. A team that wants a quick read on revenue movement can get answers without asking an analyst to export five CSV files. For early-stage SaaS companies, that matters. Founders can see churn, upgrades, downgrades, and cash flow trends in one place.
For cost of revenue, Baremetrics is more useful as a revenue intelligence layer than a full accounting system. It helps show whether revenue quality is improving. It does not automatically solve cost allocation. A finance team still needs accounting software or spreadsheets to map hosting, support, and delivery costs to gross margin.
Best fit for Baremetrics:
- Founder-led SaaS companies.
- Teams using Stripe or simple billing setups.
- Companies that need fast MRR, churn, and cash insights.
- Teams that prefer simple dashboards over complex data modeling.
Main annoyance: advanced finance teams may outgrow the structure. Baremetrics is clean and helpful, but deep segmentation or custom reporting can feel boxed in once the business adds multiple products, regions, and pricing models.
ChartMogul for SaaS Financial Reporting
ChartMogul is built for subscription analytics with stronger data controls and deeper segmentation. It is often favored by SaaS companies that need to clean billing data, track MRR movements, and report across customer groups.
ChartMogul shines when the business wants to understand revenue patterns by plan, geography, sales channel, cohort, or customer type. That level of detail helps finance and revenue teams connect subscription data to planning. It also supports stronger analysis of expansion, contraction, churn, and retention trends.
For cost of revenue, ChartMogul still does not replace a general ledger. It will not magically classify AWS bills or support salaries. But it can help identify which customer segments produce stronger revenue behavior. That insight can be paired with cost data to estimate segment-level gross margin.
Best fit for ChartMogul:
- SaaS companies with multiple plans or products.
- Teams that need cohort and segment reporting.
- Finance teams preparing board reports.
- Companies using more complex billing data.
Main annoyance: setup can take more care. If billing data is messy, expect to waste time cleaning imports, checking mappings, and fixing edge cases before reports feel reliable.
Baremetrics vs. ChartMogul: Key Differences
| Category | Baremetrics | ChartMogul |
|---|---|---|
| Ease of use | Very simple for quick SaaS metrics. | More structured, with deeper setup options. |
| Best audience | Founders and small teams. | Finance, revenue ops, and scaling SaaS teams. |
| Reporting depth | Good for core MRR and churn views. | Stronger for segmentation and cohort analysis. |
| Cost of revenue use | Helpful for revenue context, not cost accounting. | Helpful for segment analysis, not cost accounting. |
| Complexity | Lower. | Higher, but more flexible. |
Which Tool Is Better for Cost of Revenue Reporting?
Neither Baremetrics nor ChartMogul is a full cost of revenue reporting system by itself. That job belongs to accounting software, a general ledger, and a clear chart of accounts. The better question is which tool gives better revenue context for gross margin analysis.
Baremetrics is better when the company wants speed and clarity. It works well for a SaaS founder asking, “Is MRR growing, and is churn under control?”
ChartMogul is better when the company needs detailed subscription reporting by customer segment. It works well for a finance lead asking, “Which customer groups have the best retention and pricing quality?”
For true SaaS financial reporting, the best setup often pairs one subscription analytics tool with accounting data. Revenue metrics come from Baremetrics or ChartMogul. Cost categories come from the accounting system. Gross margin reporting comes from combining both.
Practical Example
A SaaS company has $500,000 in MRR. Its monthly cost of revenue includes:
- $45,000 in cloud hosting.
- $30,000 in support salaries.
- $10,000 in payment fees.
- $15,000 in onboarding and customer delivery tools.
Total cost of revenue is $100,000. Gross profit is $400,000. Gross margin is 80%.
Baremetrics can help show whether MRR is rising or churn is eating growth. ChartMogul can show whether enterprise customers retain better than self-serve customers. But the gross margin calculation still needs the cost data from accounting.
Final Recommendation
For early-stage SaaS teams, Baremetrics is often the cleaner starting point. It is fast, readable, and founder-friendly. It gives the team a solid view of subscription performance without heavy setup.
For scaling SaaS companies, ChartMogul is usually the stronger pick. It gives finance and revenue teams better segmentation and cleaner subscription analysis. That matters when board reporting, forecasting, and cohort analysis become regular work.
For cost of revenue, the tool choice should not distract from the real work: clean accounting categories, consistent cost allocation, and regular gross margin reviews.
FAQ

Does Baremetrics calculate cost of revenue?
Baremetrics focuses on subscription metrics such as MRR, churn, ARR, and revenue movement. It can support financial analysis, but cost of revenue usually comes from accounting records.
Does ChartMogul replace accounting software?
No. ChartMogul is a subscription analytics platform. It helps analyze revenue, retention, cohorts, and segments, but it does not replace a general ledger.

ChartMogul is often better for detailed board reporting because it supports deeper segmentation and cohort analysis. Baremetrics is better for quick, simple SaaS dashboards.
What gross margin should a SaaS company target?
Many healthy SaaS companies aim for gross margins around 75% to 85%. The right target depends on product type, infrastructure needs, support model, and customer segment.
