How to calculate the cost of a product and ensure your business profitability

Many entrepreneurs make a silent mistake that can put their business at risk: selling without knowing exactly how much it costs to produce or acquire each product.

Calculating the cost of a product is one of the most important pillars of a profitable company. It not only allows you to set the right prices, but also to protect your profits, make better decisions, and grow on a solid foundation.

According to Siigo Aspel, the cost of sales corresponds to the amount it costs you to manufacture or purchase a product, while the selling price is the amount the customer will pay, including the profit margin you want to obtain.

What is the cost of a product?

The cost of a product represents all the money invested to have it ready for sale. This includes much more than the purchase price or raw materials.

If you manufacture products:
  • Raw materials
  • Labor
  • Packaging
  • Electricity
  • Transportation
  • Indirect costs
If you sell finished products:
  • Purchase price
  • Freight
  • Tariffs or taxes
  • Storage costs

Why is it so important to calculate costs correctly?

When you do not know the real cost of your products, it is easy to fall into one of these mistakes:

Selling below cost.
Copying competitors' prices without analyzing your own cost structure.
Offering discounts that reduce or eliminate your profits.
Thinking the business is growing when it is actually losing money.

Elements that make up the cost of a product

Direct costs

These are those that can be easily identified in each unit produced.

  • Materials
  • Ingredients
  • Supplies
  • Direct labor
Indirect costs

These are expenses necessary to operate, but that do not belong to a specific product.

  • Rent
  • Utilities
  • Internet
  • Tools
  • Administrative salaries

Formula to calculate the cost of a product

Product cost = Direct costs + Allocated indirect costs
Practical example — Suppose you manufacture scented candles.
Concept Value
Wax $3.000
Fragrance $1.000
Container $2.000
Label $500
Labor $2.500
Indirect costs $1.000
Total cost $10.000

How to calculate the selling price

Selling price = Total cost + Profit margin

If you want to earn 50% over cost:

Cost total: $10,000
Profit: $5,000
Selling price: $15,000

VAT and other taxes

VAT directly impacts the final amount paid by the customer and should be considered as part of your pricing strategy.

In addition, if you sell through payment platforms or marketplaces, you should also consider:

  • Transaction fees
  • Withholdings
  • Financial costs

How often should you review your costs?

Costs constantly change due to inflation, supplier variations, and new operating expenses. Ideally, you should review them:

Monthly if input costs change frequently.
Quarterly if costs are stable.
Whenever suppliers or market conditions change.
Automate cost calculation and gain control
