Application: Gastronomic Harmony

States :

The company Harmonie Gastronomique specializes in the distribution of luxury food products. To make an informed decision about selling their gourmet baskets, they want to analyze various financial indicators. They provide you with the following information:

  • Purchase price excluding tax for a basket: €80
  • Sale price excluding VAT of a basket: €120
  • Quantity sold: 500 units
  • Order cost: €50
  • Annual storage cost: €2 per unit

Work to do :

  1. Calculate the unit margin of a basket.
  2. Determine the margin rate made on each basket sold.
  3. Evaluate the markup rate applied to the basket.
  4. What is the overall margin made on the sale of baskets?
  5. Calculate the QEC (Economic Order Quantity) to optimize inventory management.

Proposed correction:

  1. The unit margin is calculated by the difference between the selling price excluding tax and the purchase price excluding tax.
    Unit margin = €120 – €80 = €40.
    Each basket sold brings a margin of €40.

  2. The margin rate is calculated using the formula: ((PV HT – PA HT) ÷ PA HT) x 100.
    Margin rate = ((€120 – €80) ÷ €80) x 100 = (€40 ÷ €80) x 100 = 50%.
    The margin rate on each basket is 50%.

  3. The markup rate is obtained by the formula: ((PV HT – PA HT) ÷ PV HT) x 100.

Markup rate = ((€120 – €80) ÷ €120) x 100 = (€40 ÷ €120) x 100 = 33,33%.
The applied markup rate is 33,33%.

  1. The overall margin is obtained by multiplying the unit margin by the quantity sold.
    Overall margin = €40 x 500 = €20.
    The overall margin achieved is €20.

  2. The QEC (Economic Order Quantity) is given by: ?((2 x Annual demand x Order cost) ÷ Storage cost).
    Let QEC = ?((2 x 500 x 50) ÷ 2) = ?(50) = 000 units.
    The optimal QEC is 224 units (rounded up to the next whole number).

Formulas Used:

  • Stable resources: €150
  • Stable jobs: €120

Work to do :

  1. Calculate the margin rate on each device sold.
  2. Determine the markup rate for the devices.
  3. Evaluate the overall margin obtained from the sale of the devices.
  4. Find out the company's Net Working Capital (NWC).
  5. Suggest a strategy to improve margin or markup if they want.

Proposed correction:

  1. The margin rate is obtained by ((PV HT – PA HT) ÷ PA HT) x 100.
    Margin rate = ((€350 – €200) ÷ €200) x 100 = (€150 ÷ €200) x 100 = 75%.
    The margin rate is 75% per device.

  2. The markup rate is calculated with ((PV HT – PA HT) ÷ PV HT) x 100.
    Markup rate = ((€350 – €200) ÷ €350) x 100 = (€150 ÷ €350) x 100 = 42,86%.
    The applied markup rate is 42,86%.

  3. The overall margin is calculated by Unit Margin x Quantity Sold.

Unit margin = €150, therefore overall margin = €150 x 300 = €45.
The overall margin achieved is €45.

  1. The Net Working Capital (NWC) is given by Stable Resources – Stable Jobs.
    FRNG = €150 – €000 = €120.
    The FRNG is €30.

  2. A strategy to improve margin or markup could include increasing the selling price, reducing purchasing costs through negotiations, or reducing indirect costs related to production or distribution.

Fashion Loop, a company specializing in the manufacture of eco-friendly clothing, analyzes the profitability of one of its best-sellers. Here is the available data:

  • Purchase price excluding VAT per unit: €15
  • Selling price excluding VAT per unit: €45
  • Sales made: 1 units
  • Annual storage cost: €1,50 per unit
  • Order cost: €75
  • Annual demand: 1 units

Work to do :

  1. Determine the margin rate for each garment sold.
  2. Calculate the markup rate applied to this product.
  3. What is the overall margin made on these sales?
  4. Evaluate the economic order quantity (EOQ).
  5. Analyze how the company could increase its profitability.

Proposed correction:

  1. The margin rate is ((PV HT – PA HT) ÷ PA HT) x 100.
    Margin rate = ((€45 – €15) ÷ €15) x 100 = (€30 ÷ €15) x 100 = 200%.
    The clothes are sold with a 200% margin.

  2. The markup rate is ((PV HT – PA HT) ÷ PV HT) x 100.
    Markup rate = ((€45 – €15) ÷ €45) x 100 = (€30 ÷ €45) x 100 = 66,67%.
    The product is marketed with a brand rate of 66,67%.

  3. The overall margin is Unit Margin x Quantity Sold.

Unit margin = €30, therefore overall margin = €30 x 1 = €000.
Fashion Loop thus achieved an overall margin of €30.

  1. The QEC is determined by: ?((2 x Annual Demand x Ordering Cost) ÷ Storage Cost).
    QEC = ?((2 x 1 x 000) ÷ 75) = ?(1,50) = 100.
    The economic order quantity is therefore 317 units.

  2. To increase its profitability, Fashion Loop could explore strategies such as expanding its product range to attract more customers, negotiating better purchase rates, or increasing its prices while communicating the eco-responsible added value of the products.

  • Storage cost per unit per year: €4

Work to do :

  1. Determine the margin rate value for the stethoscope.
  2. Calculate the markup rate applied to this product.
  3. Estimate the total quantity sold during the period.
  4. Calculate QEC to optimize inventory costs.
  5. Discuss how an increase in storage costs might impact business decisions.

Proposed correction:

  1. The margin rate is obtained by ((PV HT – PA HT) ÷ PA HT) x 100.
    Margin rate = ((€75 – €45) ÷ €45) x 100 = (€30 ÷ €45) x 100 = 66,67%.
    The stethoscope's margin rate is 66,67%.

  2. The markup rate is calculated with ((PV HT – PA HT) ÷ PV HT) x 100.
    Markup rate = ((€75 – €45) ÷ €75) x 100 = (€30 ÷ €75) x 100 = 40%.
    The applied markup rate is 40%.

  3. The total quantity sold is the opening inventory minus the ending inventory.

Quantity sold = 400 – 150 = 250 units.
GreenMed Supply sold 250 units of stethoscopes.

  1. The QEC is given by: ?((2 x Annual demand x Ordering cost) ÷ Storage cost).
    With an estimated annual demand of 250 units, QEC = ?((2 x 250 x 30) ÷ 4) = ?(3) = 750.
    The QEC amounts to 62 units.

  2. An increase in the cost of storage could lead GreenMed to reduce its inventory levels to avoid high charges. This could involve ordering more frequently, but in smaller quantities, perhaps affecting economies of scale.

Proposed correction:

  1. The markup rate is ((PV HT – PA HT) ÷ PV HT) x 100.
    Markup rate = ((€25 – €10) ÷ €25) x 100 = (€15 ÷ €25) x 100 = 60%.
    The markup rate for bulbs is 60%.

  2. The margin rate is calculated by ((PV HT – PA HT) ÷ PA HT) x 100.
    Margin rate = ((€25 – €10) ÷ €10) x 100 = (€15 ÷ €10) x 100 = 150%.
    The margin rate reaches 150%.

  3. The overall margin is found by Unit Margin x Quantity Sold.

Unit margin = €15, therefore overall margin = €15 x 2 = €000.
The overall margin achieved is €30.

  1. The BFR is the result of Current Jobs – Current Resources.
    WCR = €30 – €000 = -€48.

  4. Develop a strategy to maintain optimal BFR if it turns out to be negative.
  5. Propose a strategy to improve working capital based on financial analysis.

Proposed correction:

  1. The margin rate is calculated by ((PV HT – PA HT) ÷ PA HT) x 100.
    Margin rate = ((€125 – €50) ÷ €50) x 100 = (€75 ÷ €50) x 100 = 150%.
    Each solar oven generates a margin rate of 150%.

  2. The markup rate uses the formula ((PV HT – PA HT) ÷ PV HT) x 100.
    Markup rate = ((€125 – €50) ÷ €125) x 100 = (€75 ÷ €125) x 100 = 60%.
    The markup rate is therefore 60%.

  3. The overall margin is obtained by Unit Margin x Quantity Sold.

Unit margin = €75, therefore overall margin = €75 x 1 = €200.
The overall margin achieved is €90.

  1. If the WCR is negative, a strategy could include improving inventory turnover, reducing payment terms of receivables, or optimizing the short-term financing structure.
