A product can generate thousands in sales and still contribute very little to business profit. Discounts, delivery fees, returns, marketing, storage, and customer support can quietly reduce the money left after each sale. This is why revenue alone does not tell the full story of product performance.
Businesses need product profitability analysis to understand which products truly make money, which costs reduce their margins, and where improvements are possible. For CFOs and business owners, this information supports better pricing, smarter product decisions, and more effective use of company resources.
Why Revenue Alone Cannot Show Product Profitability
Revenue measures how much money a business earns from selling products before expenses are deducted. It shows sales activity, but it does not explain how much money remains after the costs of making and selling those products.
Consider two products:
- Product A generates €100,000 in revenue but has high production, delivery, and marketing costs.
- Product B generates €65,000 in revenue but costs much less to produce, store, and sell.
Product A has higher sales, but Product B may deliver a better profit.
Looking only at revenue can lead businesses to invest more in products that bring in money but offer weak returns. A proper analysis considers the full cost of selling each product, not just its selling price or sales volume.
7 Factors to Include in Product Profitability Analysis
A useful analysis starts by identifying the costs that affect each product. Some are easy to track, while others need to be shared across products using a fair method.
1. Direct Product Costs
These are expenses directly linked to making or buying a product. They may include:
- Packaging.
- Direct production labour.
- Raw materials and components.
- Manufacturing or purchase costs.
Subtracting direct product costs from net sales gives gross profit.
Formula:
Gross Profit = Net Sales – Cost of Goods Sold
Gross margin percentage = (Gross Profit ÷ Net Sales) × 100
This is a useful starting point, but it does not include every expense involved in selling the product.
2. Discounts and Returns
A product may have a listed price of €100, but customers may often buy it for €85 after discounts. Returns and refunds can reduce net sales even further.
For a more accurate view, track:
- Original selling price.
- Refunds and returned products.
- Discounts and promotional offers.
- Cancellations and damaged goods.
Use net sales rather than the original listed price when calculating profitability. This prevents promotional activity from making a product look more profitable than it really is.
3. Marketing and Customer Acquisition Costs
Some products need more advertising to attract buyers. A product may sell well because the business spends heavily on paid campaigns, promotions, or sales commissions.
Track marketing costs by product or product group wherever possible. If a campaign supports several products, use a consistent method to share the cost.
For example, compare the marketing expense with the sales and contribution generated by each product. This helps identify products that attract customers efficiently and those that depend on expensive promotion.
4. Delivery, Storage and Fulfilment Costs
The cost of selling a product does not end when it leaves the factory or supplier. Storage, picking, packing, shipping, and handling can reduce the final margin.
Large or fragile products may cost more to store and deliver than smaller items. Some products also remain in warehouses longer, increasing storage costs.
Review these expenses by product category, shipment, or order. This can reveal why two products with similar gross margins produce different financial results.
5. Customer Support and After-Sales Costs
Some products require more support after purchase. They may generate more complaints, replacements, repairs, warranty claims, or technical questions.
These activities use employee time and may create additional expenses.
Track support requests, replacement rates, warranty costs, and service time by product. This helps reveal whether a product’s sales are creating a high support burden.
6. Contribution Margin
Contribution margin shows how much money remains after variable costs are deducted from net sales. The remaining amount helps cover fixed business expenses and contributes to profit.
Formula:
Contribution Margin = Net Sales – Variable Costs
For example, if a product sells for €100 and its variable costs total €60, its contribution margin is €40, or 40%.
This measure is useful when comparing products, reviewing promotional offers, and deciding which items deserve more attention. OpenStax explains how contribution margin supports product and pricing decisions.
7. Shared Operating Costs
Some costs support several products rather than one specific item. These can include warehouse rent, management salaries, software, utilities, and general administration.
Businesses may allocate these expenses using suitable measures such as:
- Units sold
- Employee time
- Production hours
- Storage space used
- Number of orders processed
The allocation method matters. A product should not be charged an unfair share of costs simply because it has high sales volume. Keep direct costs separate from allocated costs so decision-makers can see both the product’s contribution and its estimated fully loaded profitability.
A Simple Example of Product Profitability
Imagine a business sells two products. Both generate strong revenue, but their costs are different.
| Financial measure | Product A | Product B |
| Net sales | €50,000 | €40,000 |
| Direct product costs | €25,000 | €16,000 |
| Marketing and delivery | €12,000 | €8,000 |
| Contribution after these costs | €13,000 | €16,000 |
| Contribution margin | 26% | 40% |
Product A generates more revenue, but Product B contributes more money after the listed costs. This does not automatically mean Product B is more profitable overall. Shared operating expenses and other costs still need to be considered.
The example shows why businesses should compare margins and costs instead of ranking products by revenue alone.
How to Build a Reliable Product Profitability Report
Accurate analysis depends on having consistent information from finance, sales, inventory, marketing, and operations.
Bring Data Sources Together
Product information often sits in separate systems. Finance tracks expenses, sales records orders, and inventory systems hold stock and fulfilment details.
Connecting these sources makes it easier to compare revenue with the costs behind each sale. A reliable data consultancy can help businesses assess their systems and create a stronger foundation for reporting.
Set Clear Metrics and Reporting Rules
Decide which measures matter and how they will be calculated. Use consistent rules for discounts, returns, shipping, shared expenses, and reporting periods.
Useful measures include:
- Contribution margin.
- Net sales by product.
- Return and refund rates.
- Marketing cost per product.
- Inventory and fulfilment costs.
- Gross profit and gross margin.
A shared reporting model helps finance and management teams work with the same figures. Strong business intelligence can turn these measures into dashboards that support regular reviews.
Review Performance Over Time
One month of strong sales does not always indicate a lasting improvement. Compare profitability across months, seasons, sales channels, and customer groups.
Look for changes in costs, margins, and demand. This helps leaders understand whether a product is becoming more profitable or simply benefiting from a short-term increase in sales.
Turn Product Profitability Data Into Better Decisions
Once businesses understand which products generate healthy margins, they can make more informed choices about pricing, promotions, stock levels, and product development.
A low-margin product may need a price change, a cheaper supplier, or a more efficient delivery process. A high-margin product may deserve greater marketing investment, provided customer demand can support it.
Tenplus helps businesses connect scattered data, improve reporting, and build reliable analytics foundations. If your current reports show revenue but leave you unsure about the profit behind each product, a profit visibility review can help identify missing cost data, reporting gaps, and useful next steps.
The aim is to move beyond asking which products sell the most and start understanding which products create the strongest financial value for the business.
FAQs
What is product profitability analysis?
Product profitability analysis is the process of measuring how much profit each product generates after accounting for the costs involved in making, marketing, selling, and delivering it.
What is the difference between product revenue and product profit?
Revenue is the money generated from sales before expenses are deducted. Product profit is what remains after relevant costs are subtracted. A product can have high revenue but low profit if its costs are also high.
Which costs should be included in product profitability?
Businesses should consider direct product costs, discounts, returns, marketing, delivery, storage, customer support, and a fair share of relevant operating expenses.
How often should businesses measure product profitability?
Many businesses review product profitability monthly or quarterly. Companies with changing prices, high sales volumes, or frequent promotions may benefit from more frequent reviews.
How can data analytics improve product profitability?
Data analytics brings sales, finance, inventory, and marketing information together. It helps businesses compare costs and margins, identify weak-performing products, and make better pricing and investment decisions.
