Application: Planet Fashion

States :

Planète Mode is an organic and ethical clothing store that wants to analyze the profitability of different items. You have received data regarding some of the items that need special attention in order to improve the pricing strategy.

Work to do :

  1. Calculate the selling price excluding VAT of a t-shirt if the purchase price excluding VAT is €20 and the desired markup rate is 40%.
  2. Determine the margin rate of a dress sold for €70 excluding tax, knowing that its purchase price excluding tax is €55.
  3. A pair of jeans costs €35 excluding VAT to buy and is sold for €60 excluding VAT. Find the brand rate.
  4. You need to lower the selling price of a dress by 15% to increase sales. The original selling price is €80. What will the new selling price be?
  5. How would the overall margin vary if the quantity of jackets sold is doubled (100 jackets) knowing that the unit margin excluding tax is €25?

Proposed correction:

  1. To obtain a markup rate of 40%, we use the formula: PV HT = PA HT ÷ (1 – Markup rate).
    Substituting, €20 ÷ (1 – 0,40) = €33,33.
    The selling price excluding VAT should be €33,33 to achieve a mark-up rate of 40%.

  2. The margin rate is calculated as follows: ((PV HT – PA HT) ÷ PA HT) x 100.
    Substituting, ((70 – 55) ÷ 55) x 100 = 27,27%.
    The markup on the dress is 27,27%.

  3. The mark rate is given by: ((PV HT – PA HT) ÷ PV HT) x 100.

Applying the values, ((60 – 35) ÷ 60) x 100 = 41,67%.
So, the markup rate for jeans is 41,67%.

  1. To decrease the price by 15%, we multiply the initial price by (1 – 0,15).
    Replacing, €80 x (1 – 0,15) = €68.
    The new selling price excluding VAT will be €68.

  2. The overall margin is: Unit margin x Quantity sold. If the quantity doubles, the new overall margin is: €25 x 100 = €2.
    Thus, the doubled overall margin would amount to €2.

Formulas Used:

  4. Determine the margin rate of a product purchased for €18 excluding tax and sold for €25 excluding tax.
  5. Consider the unit margin of a dietary supplement set at €5 and 200 units sold. What is the overall margin? If the quantity sold increases by 50%, how does the overall margin change?

Proposed correction:

  1. The purchase price excluding tax is obtained by the formula: PA excluding tax = PV excluding tax ÷ (1 + Margin rate).
    By replacing, €40 ÷ (1 + 0,25) = €32.
    The purchase price excluding VAT of the box of vitamins is €32.

  2. The purchase price excluding tax is determined by: PA excluding tax = PV excluding tax x (1 – Markup rate).
    Replacing, €24 x (1 – 0,30) = €16,80.
    The purchase price excluding VAT of the essential oil is €16,80.

  3. The new selling price is: New PV HT = PV HT x (1 + Increase %).

By replacing, €15 x (1 + 0,10) = €16,50.
Therefore, the new selling price excluding VAT for the pack of tea will be €16,50.

  1. The margin rate is calculated: ((PV HT – PA HT) ÷ PA HT) x 100.
    Substituting, ((25 – 18) ÷ 18) x 100 = 38,89%.
    The margin rate for this product is 38,89%.

  2. The initial overall margin is: €5 x 200 = €1. With a 000% increase, the quantity is 50 units and therefore: €300 x 5 = €300.
    The overall margin would increase to €1.

  5. For a charging system offered at €400 excluding VAT and a brand rate of 25%, what is its purchase price excluding VAT?

Proposed correction:

  1. The markup rate is calculated as follows: ((PV HT – PA HT) ÷ PV HT) x 100.
    Substituting, ((500 – 350) ÷ 500) x 100 = 30%.
    So the battery mark rate is 30%.

  2. The selling price excluding tax is given by: PV excluding tax = PA excluding tax x (1 + Margin rate).
    Substituting, €1 x (200 + 1) = €0,30.
    Therefore, the solar panel must be sold for €1 excluding VAT to obtain a 560% margin.

  3. The reduced price is calculated by: New PV excluding VAT = PV excluding VAT x (1 – Reduction %).

Substituting, €2 x (000 – 1) = €0,12.
The new selling price excluding tax for the wind turbines will be €1.

  1. Initial overall margin = Unit margin x Quantity = €150 x 50 = €7.
    If sales increase by 20%, quantity = 60 then,
    New overall margin = €150 x 60 = €9.
    The new overall margin would be €9.

  2. The purchase price is determined by: PA HT = PV HT x (1 – Markup rate).
    Replacing, €400 x (1 – 0,25) = €300.
