May 3, 2025•5-minute read•By Edson Clementino da Silva

Introduction

In retail, setting the right price requires balancing fixed and variable costs, margin expectations, and competitive positioning. A structured calculation ensures profitability without driving customers away.

1. Identifying Cost Components

To get started, break down your costs into:

  • Acquisition cost: price paid to the supplier
  • Variable costs: shipping, sales commissions, packaging
  • Allocated fixed costs: rent, utilities, and salaries allocated per unit

Adding everything together gives you the Total Unit Cost (TUC).

2. Setting the Desired Margin

The profit margin (%) is calculated as:

Margin (%)=Selling Price−CTUSelling Price×100\text{Margin (\%)} = \frac{\text{Selling Price} - \text{CTU}}{\text{Selling Price}} \times 100Margin (%)=Selling PriceSelling Price−CTU​×100

To calculate the selling price based on the markup, use:

Selling Price=CTU1−Desired Margin100\text{Selling Price} = \frac{\text{CTU}}{1 - \frac{\text{Desired Margin}}{100}}Selling Price=1−100Desired Margin​CTU​

3. Practical Example

Suppose:

  • CTU = R$50.00
  • Desired Margin = 40%

Therefore:

Selling Price=501−0,40=500,60≈R$83,33\text{Selling Price} = \frac{50}{1 - 0{,}40} = \frac{50}{0{,}60} \approx R\$ 83,33Selling Price=1−0,4050​=0,6050​≈R$83,33

4. Point-of-Sale Price Adjustment

Consider market factors:

  • Competition: align prices with similar offerings
  • Value perception: strategic discounts can increase sales volume
  • Seasonality: adjust margins during periods of high or low demand

Adjust your markup within the range consumers find acceptable.

5. Continuous Monitoring and Review

  • Sales vs. actual cost analysis: compare projected CTU with actual CTU
  • Monthly margin reports: identify variances and their causes
  • Periodic price adjustments: reflect changes in costs or the market

Consistent monitoring ensures sustainable profits.

Conclusion

Calculating margins systematically and reviewing them regularly helps retailers stay competitive and profitable. With a clear method and regular adjustments, you can optimize prices and strengthen your market position.
