Application: Gourmet Bakery

States :

Boulangerie Gourmande, located in Paris, wants to evaluate its sales performance of chocolate cakes. Manufacturing costs and sales prices must be analyzed to make strategic decisions. You have the following information: the cost of purchasing ingredients per cake is €8, the production cost per cake is €5, and the sales price excluding tax is €20. The bakery sold 500 cakes.

Work to do :

  1. Calculate the total cost of ingredients and production for all cakes sold.
  2. Determine the unit margin.
  3. Calculate the overall margin made by the bakery on these sales.
  4. Determine the margin rate.
  5. Analyze the impact of a 5% increase in the net selling price on the unit margin.

Proposed correction:

  1. To calculate the total cost of ingredients and production for all cakes, use the following formula:
    Total cost = (Purchase cost + Production cost) x Quantity sold.
    Replacing, (€8 + €5) x 500 = €6.
    The total cost is €6.

  2. To determine the unit margin, use the formula:
    Unit margin = Selling price excluding tax – (Purchase cost + Production cost).
    Replacing, €20 – (€8 + €5) = €7.
    The unit margin is €7.

  3. To calculate the overall margin:

Overall margin = Unit margin x Quantity sold.
Replacing, €7 x 500 = €3.
The overall margin is €3.

  1. The margin rate is calculated using the formula:
    Margin rate = ((PV HT – PA HT) ÷ PA HT) x 100.
    Substituting, ((€20 – (€8 + €5)) ÷ (€8 + €5)) x 100 = 53,85%.
    The margin rate is 53,85%.

  2. To analyze the impact of a 5% increase in the net selling price, calculate the new selling price:
    New PV HT = PV HT x (1 + 0,05).
    Replacing, €20 x 1,05 = €21.
    New unit margin = €21 – (€8 + €5) = €8.
    The increase in the selling price results in a unit margin of €8, thus increasing the margin per cake.

Formulas Used:

Title Formulas
Total cost (Purchase cost + Production cost) x Quantity sold
Unit margin Selling price excluding VAT – (Purchase cost + Production cost)
Overall margin Unit margin x Quantity sold
Margin rate ((PV HT – PA HT) ÷ PA HT) x 100
New PV HT PV HT x (1 + Percentage increase)

Work to do :

  1. Calculate the total manufacturing cost for all units sold.
  2. Determine the unit margin for a tablet.
  3. Calculate the overall margin generated by sales.
  4. Calculate the markup rate.
  5. Calculate the new unit margin if the manufacturing cost is reduced by 10%.

Proposed correction:

  1. The total manufacturing cost is calculated by:
    Total Cost = Manufacturing Cost x Quantity Sold.
    Replacing, €120 x 1500 = €180.
    The total manufacturing cost is €180.

  2. The unit margin is determined by:
    Unit margin = Selling price excluding tax – Manufacturing cost.
    As a replacement, €320 – €120 = €200.
    The unit margin is €200.

  3. The overall margin is calculated by:

Overall margin = Unit margin x Quantity sold.
Replacing, €200 x 1500 = €300.
The overall margin is €300.

  1. The markup rate is calculated with the formula:
    Mark rate = ((PV HT – PA HT) ÷ PV HT) x 100.
    Replacing, ((€320 – €120) ÷ €320) x 100 = 62,5%.
    The markup rate is 62,5%.

  2. The new unit margin with a 10% reduction in cost is:
    New manufacturing cost = Manufacturing cost x (1 – 0,10).
    Replacing, €120 x 0,90 = €108.
    New unit margin = €320 – €108 = €212.
    The cost reduction improves the unit margin to €212.

Formulas Used:

Title Formulas

  2. Determine the unit margin.
  3. Calculate the overall margin achieved on this range.
  4. Determine the margin rate.
  5. Evaluate the impact of a 15% reduction in selling price on unit margin.

Proposed correction:

  1. The total cost of raw materials and manufacturing is calculated by:
    Total Cost = (Material Cost + Manufacturing Cost) x Quantity Sold.
    Replacing, (€150 + €50) x 200 = €40.
    The total cost is €40.

  2. The unit margin is calculated by:
    Unit margin = Selling price excluding tax – (Cost of materials + Manufacturing cost).
    Replacing, €400 – (€150 + €50) = €200.
    The unit margin is €200.

  3. The overall margin is determined by:

Overall margin = Unit margin x Quantity sold.
Replacing, €200 x 200 = €40.
The overall margin is €40.

  1. The margin rate is calculated using the formula:
    Margin rate = ((PV HT – PA HT) ÷ PA HT) x 100.
    Substituting, ((€400 – (€150 + €50)) ÷ (€150 + €50)) x 100 = 100%.
    The margin rate is 100%.

  2. The impact of a 15% reduction is assessed by:
    New PV HT = PV HT x (1 – 0,15).
    Replacing, €400 x 0,85 = €340.
    New unit margin = €340 – (€150 + €50) = €140.
    The unit margin after reduction would be €140, and this would reduce unit profitability.
