Application: Gourmet House

States :

Maison Gourmande is a neighborhood bakery that wants to review its pricing strategy for several of its products. It recently introduced a new cake and is looking to determine the optimal selling price that will allow it to maximize its margin while remaining competitive. The purchase price excluding tax is €8 per unit. The managers want a markup rate of 30% for this product. In addition, the expected annual demand for this cake is 500 units.

Work to do :

  1. Calculate the selling price excluding tax that would allow you to achieve the desired markup rate.
  2. Determine the amount of VAT to apply (20%) to obtain the sales price including VAT.
  3. Calculate the unit margin of this cake.
  4. Evaluate the overall margin for a full year.
  5. Analyze the impact on revenue if demand exceeds forecasts by 10%.

Proposed correction:

  1. To obtain a markup rate of 30%, we use the formula:
    PV HT = PA HT ÷ (1 – Mark rate).
    Substituting, €8 ÷ (1 – 0,30) = €11,43.
    The selling price excluding VAT should be €11,43 to achieve the desired markup rate.

  2. To find the sales price including tax, we apply the VAT of 20%:
    VAT = PV HT x 0,20.
    VAT = €11,43 x 0,20 = €2,29.
    The sales price including tax is therefore €11,43 + €2,29 = €13,72.

  3. The unit margin is calculated by:

Unit margin = PV HT – PA HT.
Unit margin = €11,43 – €8 = €3,43.
The unit margin for this cake is €3,43.

  1. The annual overall margin is:
    Overall margin = Unit margin x Quantity sold.
    Overall margin = €3,43 x 500 = €1715.
    For a full year, the overall margin is €1715.

  2. If demand increases by 10%, it increases to 500 + (500 x 0,10) = 550 cakes.
    New turnover = 550 x €13,72 = €7546.
    The increase in demand would lead to an increase in turnover to €7546.

Application: TechnoWorld

States :

TechnoWorld, a supplier of electronic devices, must set the selling price of a new camera whose purchase cost is €200 excluding VAT. To remain competitive, the company wants to guarantee a margin rate of 40%. In addition, they anticipate a sales volume of 1 units over the year.

Work to do :

  1. Calculate the optimal selling price excluding tax to achieve the margin rate of 40%.
  2. Calculate the VAT rate at 20% on this selling price excluding VAT.
  3. Estimate the profit made per unit sold.
  4. Determine the overall margin if expected demand is met.
  5. Analyze the impact on cash flow if storage costs represent 5% of turnover.

Proposed correction:

  1. We use the formula for the margin rate:
    PV HT = PA HT ÷ (1 – Margin rate).
    PV excluding tax = €200 ÷ (1 – 0,40) = €333,33.
    The optimal selling price excluding VAT is €333,33.

  2. To calculate VAT at 20%:
    VAT = PV HT x 0,20.
    VAT = €333,33 x 0,20 = €66,67.
    The sales price including tax is therefore €333,33 + €66,67 = €400.

  3. The profit per unit sold is:

Unit profit = PV excluding tax – PA excluding tax.
Unit profit = €333,33 – €200 = €133,33.
The profit per unit is €133,33.

  1. The annual overall margin is:
    Overall margin = Unit profit x Quantity sold.
    Total margin = €133,33 x €1 = €200.
    The overall expected margin is therefore €160.

  2. If the storage cost is 5% of turnover:
    Turnover = €333,33 x 1 = €200.
    Storage cost = €399 x 996 = €0,05.
    The storage cost will amount to €19 and will affect cash flow accordingly.

Application: Green Line Wines

States :

Ligne Verte Vins is a winery specializing in organic wines. They recently acquired a selection of rare wines at a purchase price excluding tax of €45 per bottle. Their goal is to set a margin rate of 55%. The expected annual sale for these bottles is 200 units.

Work to do :

  1. Determine the selling price excluding tax that would allow Ligne Verte Vins to respect their desired margin rate.
  2. Calculate the sales price including VAT of 20%.
  3. Calculate the unit margin for each bottle sold.
  4. Determine the expected annual overall margin.
  5. Discuss the implications for net profit if a promotion will offer a 10% discount on the inclusive price.

Proposed correction:

  1. With a margin rate of 55%, the formula applied is:
    PV HT = PA HT ÷ (1 – Margin rate).
    PV excluding tax = €45 ÷ (1 – 0,55) = €100.
    The selling price excluding VAT should be €100.

  2. To determine the sales price including tax:
    VAT = PV HT x 0,20.
    VAT = €100 x 0,20 = €20.
    So, the sales price including tax is €100 + €20 = €120.

  3. The unit margin is calculated by:

Unit margin = PV HT – PA HT.
Unit margin = €100 – €45 = €55.
The unit margin is €55.

  1. The overall margin is deduced by:
    Overall margin = Unit margin x Quantity sold.
    Overall margin = €55 x 200 = €11.
    The expected overall margin is €11 per year.

  2. During a promotion with a 10% reduction on the price including tax:
    New Price including VAT = €120 – (€120 x 0,10) = €108.
    Profit per bottle after promo = (€108 ÷ 1,2) – €45 = €45.
    Although reduced, net profit sees a decrease.

Application: EcoDesign

States :

EcoDesign offers innovative eco-friendly furniture. A new collection has a purchase cost of €600 excluding VAT per piece. The company wants to review its sales price so that the mark-up rate is 35%. The company projects a sales volume of 300 units for this offer.

Work to do :

  1. Calculate the selling price excluding tax required to achieve the desired markup rate.
  2. Determine the sales price including tax, taking into account 20% VAT.
  3. Calculate the unit margin obtained from the fixed selling price.
  4. Estimate the overall margin made on the entire collection.
  5. Discuss the implications of increasing costs to €650 excluding VAT and what the new selling price excluding VAT would be to maintain the initial mark-up rate.

Proposed correction:

  1. The calculation to obtain a markup rate of 35% is:
    PV HT = PA HT ÷ (1 – Mark rate).
    PV excluding tax = €600 ÷ (1 – 0,35) = €923,08.
    The selling price excluding VAT must be set at €923,08.

  2. To establish the sales price including tax:
    VAT = PV HT x 0,20.
    VAT = €923,08 x 0,20 = €184,62.
    The sales price including tax is therefore €923,08 + €184,62 = €1.

  3. The unit margin is calculated by:

Unit margin = PV HT – PA HT.
Unit margin = €923,08 – €600 = €323,08.
The unit margin is €323,08.

  1. The overall margin is:
    Overall margin = Unit margin x Quantity sold.
    Overall margin = €323,08 x 300 = €96.
    The overall margin for the collection should be €96.

  2. If the purchase cost increases to €650 excluding VAT:
    New PV excluding tax = €650 ÷ (1 – 0,35) = €1.
    To maintain a markup rate of 35%, the new PV excluding tax must be €1.

Application: InnovMobiles

States :

The start-up InnovMobiles, specializing in connected accessories, is looking to introduce a smart bracelet to the market. The purchase price of each bracelet is €30 excluding VAT. In order to get ahead of the competition, they want to set a sales price offering a margin rate of 25%. The sales forecast is 5 units for the first year.

Work to do :

  1. Calculate the selling price excluding tax targeted by InnovMobiles to obtain the desired margin rate.
  2. Determine the sales price including tax, taking into account the 20% VAT.
  3. Determine the unit margin achievable with this selling price.
  4. Calculate the total annual margin based on the sales projection.
  5. Evaluate the impact on revenue if, after six months, the company decides to lower the price by 5% to stimulate additional sales.

Proposed correction:

  1. To obtain a margin rate of 25%, you must calculate:
    PV HT = PA HT ÷ (1 – Margin rate).
    PV excluding tax = €30 ÷ (1 – 0,25) = €40.
    The selling price excluding VAT should be set at €40.

  2. To calculate the sales price including tax:
    VAT = PV HT x 0,20.
    VAT = €40 x 0,20 = €8.
    The sales price including tax is therefore €40 + €8 = €48.

  3. The unit margin is obtained as follows:

Unit margin = PV HT – PA HT.
Unit margin = €40 – €30 = €10.
The unit margin is therefore €10.

  1. The total annual margin would be:
    Overall margin = Unit margin x Quantity sold.
    Total margin = €10 x €5 = €000.
    The expected annual margin is €50.

  2. If the price is reduced by 5% after six months:
    New PV including VAT = €48 – (€48 x 0,05) = €45,60.
    New PV excluding VAT = €45,60 ÷ 1,20 = €38.
    The price adjustment affects the turnover dynamics, with re-evaluated forecasts.

Application: BioCosmetics

States :

BioCosmetics is preparing to launch a new line of organic moisturizing creams. The purchase price of the boxes of cream is €15 excluding VAT each. They are aiming for a 20% markup rate to remain profitable and competitive on the market. 3 units are planned for sale for the launch.

Work to do :

  1. Note the selling price excluding tax that BioCosmetics should apply to reach the set markup rate.
  2. Calculate the sales price including VAT by adding the applicable VAT of 20%.
  3. Calculate the margin obtained per unit sold.
  4. Calculate the total margin expected for the entire sale.
  5. Imagine a scenario where production costs increase by €5 per unit. What should the new selling price excluding VAT be to maintain the same markup rate?

Proposed correction:

  1. For a markup rate of 20%, we calculate:
    PV HT = PA HT ÷ (1 – Mark rate).
    PV excluding tax = €15 ÷ (1 – 0,20) = €18,75.
    The selling price excluding VAT should be €18,75.

  2. The sales price including tax is obtained as follows:
    VAT = PV HT x 0,20.
    VAT = €18,75 x 0,20 = €3,75.
    The sales price including tax is therefore €18,75 + €3,75 = €22,50.

  3. The unit margin is:

Unit margin = PV HT – PA HT.
Unit margin = €18,75 – €15 = €3,75.
So the unit margin is €3,75.

  1. The overall margin is expected to be:
    Total margin = Unit margin x Quantity sold.
    Total margin = €3,75 x 3 = €000.
    The total expected margin is €11.

  2. If the cost increases by €5 per cream, i.e. €20 excluding VAT:
    New PV excluding VAT = €20 ÷ (1 – 0,20) = €25.
    Therefore, to maintain the same markup rate, the new selling price excluding tax must be €25.

Application: Art&Luxury

States :

Art&Luxe, an art gallery, offers a set of high-quality sculptures. The cost of manufacturing each piece is €500 excluding VAT. The goal is to achieve a margin rate of 50%. The gallery is preparing to sell 50 units per year.

Work to do :

  1. Calculate the selling price excluding tax to reach the target margin rate.
  2. Evaluate the sales price including VAT by adding the VAT of 5,5%.
  3. Calculate the unit margin made on each sale.
  4. Determine the total margin achieved if all sculptures are sold.
  5. Consider the impact that a 10% discount on the all-inclusive price could have during a promotional sale.

Proposed correction:

  1. The PV HT corresponding to the margin rate of 50% is calculated by:
    PV HT = PA HT ÷ (1 – Margin rate).
    PV excluding tax = €500 ÷ (1 – 0,50) = €1.
    Therefore, the selling price excluding VAT must be €1.

  2. The sales price including tax is:
    VAT = PV HT x 0,055.
    VAT = €1 x 000 = €0,055.
    The sales price including tax is €1 + €000 = €55.

  3. The unit margin is obtained by:

Unit margin = PV HT – PA HT.
Unit margin = €1 – €000 = €500.
The unit margin is €500 per sculpture.

  1. The total margin for all sales is:
    Total Margin = Unit Margin x Quantity.
    Total margin = €500 x €50 = €25.
    The total margin achieved will amount to €25.

  2. During a promotion with a 10% reduction on the price including tax:
    Price with discount = €1 – (€055 x 1) = €055.
    The 10% discount could attract more buyers, while reducing the unit margin.

Application: SolarTech

States :

SolarTech offers solar installations. Their new offer includes panels purchased at €150 excluding VAT each. They want a sales price that includes a 45% markup. 800 units of solar panels are part of the sales forecast for the next quarter.

Work to do :

  1. Find the required selling price excluding VAT for the expected markup rate.
  2. Establish the sales price including tax by adding VAT at 20%.
  3. Identify the margin generated per unit sold.
  4. Calculate the total amount of projected margin.
  5. Present the effect of cost optimization that lowers the purchase cost to €140 excluding VAT and how this influences the margin.

Proposed correction:

  1. The formula for the selling price excluding VAT in order to obtain the desired markup rate is:
    PV HT = PA HT ÷ (1 – Mark rate).
    PV excluding tax = €150 ÷ (1 – 0,45) = €272,73.
    The selling price excluding VAT must be €272,73.

  2. To obtain the sales price including tax, we have:
    VAT = PV HT x 0,20.
    VAT = €272,73 x 0,20 = €54,55.
    The sales price including tax will therefore be €272,73 + €54,55 = €327,28.

  3. The margin per unit sold is calculated as follows:

Unit margin = PV HT – PA HT.
Unit margin = €272,73 – €150 = €122,73.
Therefore, the unit margin is €122,73.

  1. To know the total projected margin, we devote:
    Total Margin = Unit Margin x Expected Quantity Sold.
    Total margin = €122,73 x €800 = €98.
    So the total margin will be €98.

  2. With a reduction in the purchase cost to €140 excluding VAT:
    New Unit Margin = €272,73 – €140 = €132,73.
    Lower costs improve unit margin while providing pricing flexibility.

Application: GourmetMarket

States :

GourmetMarket specializes in the sale of gourmet products. The company plans to launch a gourmet basket for the holidays, including various products for a total purchase cost of €100 excluding VAT. They are aiming for a margin rate of 45%. 500 baskets are expected to be sold during the season.

Work to do :

  1. Calculate the selling price excluding tax required to achieve the expected margin rate.
  2. Determine the sales price including VAT, taking into account the 5,5% VAT.
  3. Calculate the margin per basket sold.
  4. Deduct the estimated overall margin on all basket sales.
  5. Imagine a change in strategy that would increase the margin rate to 50%, and calculate the new required selling price excluding VAT.

Proposed correction:

  1. To achieve the 45% margin rate, the formula is:
    PV HT = PA HT ÷ (1 – Margin rate).
    PV excluding tax = €100 ÷ (1 – 0,45) = €181,82.
    The necessary selling price excluding tax is therefore €181,82.

  2. To obtain the sales price including tax:
    VAT = PV HT x 0,055.
    VAT = €181,82 x 0,055 = €10.
    The sales price including tax will be €181,82 + €10 = €191,82.

  3. The unit margin is:

Unit margin = PV HT – PA HT.
Unit margin = €181,82 – €100 = €81,82.
The unit margin for each basket is €81,82.

  1. The overall margin is evaluated as:
    Total margin = Unit margin x Quantity sold.
    Total margin = €81,82 x €500 = €40.
    The overall expected margin is therefore €40.

  2. By increasing the margin rate to 50%:
    New PV excluding VAT = €100 ÷ (1 – 0,50) = €200.
    The new selling price excluding tax must be €200 to obtain this margin rate.
