Understanding your COGS formula is key to knowing where your SaaS business is really spending money. What looks like a simple metric often hides insights that directly impact profitability and scalability.

In this guide, we will break down what you need to know to start analyzing your costs the right way. 

Let’s begin!

What Is Cost of Goods Sold (COGS)?

COGS (Cost of Goods Sold) is the total amount a company spends directly to produce or deliver the goods and services it sells within a specific period. In simple terms, it reflects the direct costs required to generate revenue, excluding expenses like marketing, sales, and administration.

These costs usually include materials, labor, and production-related overheads for physical goods. However, in SaaS businesses COGS can cover hosting, customer support, and software infrastructure; everything essential to deliver value to customers.

How Do You Calculate COGS?

To calculate the Cost of Goods Sold, you need to identify all direct costs required to produce or deliver a product or service during a specific period.

Traditional Businesses COGS vs SaaS COGS: Key Differences

In traditional businesses, COGS is tied to physical production. But in SaaS companies, COGS focuses on digital service delivery. Instead of inventory or materials, costs are linked to infrastructure, software operations, and customer support needed to keep the platform running.

Traditional Businesses COGS Formula

In traditional, inventory-based businesses, COGS is calculated using the following formula:

COGS = Opening inventory + Purchases during the period – Closing inventory

This approach works well for physical goods, where inventory is produced, stored, and sold.

SaaS COGS Formula

For SaaS businesses, the calculation needs to be adjusted. Since there is no physical inventory, COGS focuses on direct service delivery costs rather than stock levels.

SaaS COGS = Infrastructure + Usage-Based Services + Transaction Costs + Direct Service Delivery

Where:

• Infrastructure = compute, hosting, bandwidth, storage
• Usage-Based Services = APIs, AI tokens, email/SMS, data processing
• Transaction Costs = payment processing fees, refunds, chargebacks
• Direct Service Delivery = customer support, DevOps, SRE (only the portion that scales with customers)

COGS Formula in SaaS Example

For a SaaS company with $50,000 in Monthly Recurring Revenue (MRR), monthly variable costs might look like this:

• Hosting & cloud infrastructure: $6,000
• Usage-based APIs (email, AI, data): $2,500
• Payment processing fees: $1,450
• Customer support (direct, usage-linked): $3,000
• DevOps / SRE (delivery-related portion): $2,050

COGS = 6,000 + 2,500 + 1,450 + 3,000 + 2,050 = $15,000 per month

How to Calculate SaaS COGS in Excel?

To calculate SaaS COGS in Excel or Google Sheets, follow these steps:

Step 1: Define Your SaaS COGS Categories

Start by listing all cost categories that are directly tied to delivering your product. Common SaaS COGS categories include cloud infrastructure, usage-based tools, payment processing fees, customer support, and DevOps or SRE costs that scale with customers.

Step 2: Enter Monthly Costs in Excel

Create a simple table in Excel with one column for cost categories and another for monthly amounts. Each row should represent a single COGS component, such as hosting, APIs, or support. Make sure to include only costs that increase as your customer base grows.

Step 3: Calculate Total SaaS COGS

Once all costs are entered, use Excel’s SUM function to calculate total COGS for the period. This gives you a clear view of your total delivery cost for that month or quarter and allows you to track how COGS evolves as revenue increases.

What Is a Good COGS Percentage for SaaS?

A good COGS percentage for SaaS is between 15% and 25% of total revenue, based on recent industry benchmarks from Wünder_Talent and ConsultEFC. This range reflects the typical direct cost structure of SaaS companies delivering software at scale.

Within this range, SaaS businesses can maintain strong gross margins while covering essential delivery costs like cloud infrastructure, platform maintenance, and customer support. Companies at the lower end typically benefit from more efficient infrastructure and scalable support models.

As SaaS companies grow, COGS often decreases as a percentage of revenue, since delivery costs scale more slowly than sales. Staying within this benchmark is commonly linked to gross margins above 70% and long term profitability.

Understanding and managing COGS is crucial for SaaS businesses. A lower COGS percentage signifies a more efficient operation and provides more room for investment in growth and innovation.

COGS Formula FAQs

How to Calculate Profit with COGS?

To calculate profit with COGS, you subtract COGS from total revenue to obtain gross profit. This calculation shows how much money remains after covering the direct costs of delivering your product or service.

Is COGS Equal to Gross Profit?

No, COGS is not equal to gross profit. COGS represents the direct costs of producing or delivering a product, while gross profit is the result of subtracting COGS from revenue.

In simple terms, COGS is a cost metric, and gross profit is a profitability metric derived from it.

Is COGS an Income or Expense?

COGS is an expense. It reflects the direct costs incurred to generate revenue during a specific period and is reported on the income statement.

However, unlike operating expenses, COGS is deducted from revenue first to calculate gross profit, which makes it a foundational metric in financial analysis.

Are COGS the Same as Margins?

No, COGS is not the same as margins. COGS measures costs, while margins measure profitability as a percentage of revenue.

Margins, such as gross margin, are calculated using COGS and revenue, helping you understand how efficiently your business converts sales into profit.
