Application: Bakery Pastry Sweetness

States :

Boulangerie Pâtissière Douceur wants to adjust its pricing strategies to maximize profits. Currently, it sells an apple pie at a sales price excluding tax (STP) of €8 and purchases it at a purchase price excluding tax (PPT) of €5. They plan to produce 1000 pies this year. Managers would like to better understand the cost and margin structure to make informed decisions.

Work to do :

  1. Calculate the current margin rate on the sale of the apple pie.
  2. Determine the markup rate applied to the apple pie.
  3. If the sales price including VAT at 5,5% is applied, what would the price including VAT be?
  4. Estimate the overall margin made if all the pies are sold.
  5. Consider a 10% discount on the PV HT. What would be the new margin rate?

Proposed correction:

  1. The margin rate = ((PV HT – PA HT) ÷ PA HT) x 100.

    Substituting, ((8 – 5) ÷ 5) x 100 = 60%.
    The current margin rate is 60%.

  2. The mark rate = ((PV HT – PA HT) ÷ PV HT) x 100.

    Substituting, ((8 – 5) ÷ 8) x 100 = 37,5%.
    The applied markup rate is 37,5%.

  3. The price including tax = PV excluding tax x (1 + VAT rate).

Replacing, 8 x (1 + 0,055) = €8,44.
The price including tax would be €8,44.

  1. Overall margin = Unit margin x quantity sold.

    Substituting, (8 – 5) x 1000 = €3000.
    The overall margin achieved would be €3000.

  2. New PV HT = initial PV HT x (1 – reduction).

    Substituting, 8 x (1 – 0,10) = €7,2.

    New margin rate = ((7,2 – 5) ÷ 5) x 100 = 44%.
    After a 10% reduction in the PV excluding tax, the new margin rate would be 44%.

  5. If the cost of production increases by €5 per unit, what would be the new margin rate?

Proposed correction:

  1. The margin rate = ((PV HT – PA HT) ÷ PA HT) x 100.

    Substituting, ((50 – 30) ÷ 30) x 100 = 66,67%.
    The margin rate for the gadget is 66,67%.

  2. The mark rate = ((PV HT – PA HT) ÷ PV HT) x 100.

    Substituting, ((50 – 30) ÷ 50) x 100 = 40%.
    The markup rate for the gadget is 40%.

  3. The price including tax = PV excluding tax x (1 + VAT rate).

Replacing, 50 x (1 + 0,20) = €60.
The sales price including tax would be €60.

  1. Overall margin = Unit margin x quantity sold.

    Substituting, (50 – 30) x 2000 = €40000.
    The overall margin would be €40000.

  2. New HT PA = HT PA + Cost increase.

    By replacing, 30 + 5 = €35.

    New margin rate = ((50 – 35) ÷ 35) x 100 = 42,86%.

    Substituting, ((45 – 20) ÷ 20) x 100 = 125%.
    The margin rate for each garment is 125%.

  2. The mark rate = ((PV HT – PA HT) ÷ PV HT) x 100.

    Substituting, ((45 – 20) ÷ 45) x 100 = 55,56%.
    The markup rate on a garment is 55,56%.

  3. The price including tax = PV excluding tax x (1 + VAT rate).

Replacing, 45 x (1 + 0,055) = €47,48.
The sales price including tax would be €47,48.

  1. Overall margin = Unit margin x quantity sold.

    Substituting, (45 – 20) x 1500 = €37500.
    The expected overall margin would be €37500.

  2. New PV HT = PV HT + Price increase.

    By replacing, 45 + 3 = €48.

Proposed correction:

  1. The margin rate = ((PV HT – PA HT) ÷ PA HT) x 100.

    Substituting, ((120 – 70) ÷ 70) x 100 = 71,43%.
    The margin rate on the Bluetooth speaker is 71,43%.

  2. The mark rate = ((PV HT – PA HT) ÷ PV HT) x 100.

    Substituting, ((120 – 70) ÷ 120) x 100 = 41,67%.
    The applied markup rate is 41,67%.

  3. The price including tax = PV excluding tax x (1 + VAT rate).

Replacing, 120 x (1 + 0,20) = €144.
The selling price of the speaker including tax is €144.

  1. Overall margin = Unit margin x quantity sold.

    Substituting, (120 – 70) x 1200 = €60000.
    The total margin would be €60000.

  2. Discount on PV HT = PV HT x Discount.

    New PV HT = PV HT – Discount.

    By replacing, Discount = 120 x 0,10 = €12 and
