from where : PV HT = VAT collected ÷ VAT rate

500 ÷ 0,2 = €2

 

Interpretation of the result

The sales price excluding tax is therefore €2.

 

13/ Commercial calculations: PV HT – Margin – Margin rate

States

You work as an intern at the Carrège company to help them set the selling price of a product.

She tells you that the charges on purchases are estimated at 45% of purchases.

The company typically achieves a margin of around 20% on its sales.

The purchase price of the product is €220 excluding VAT.

It also specifies that the applicable VAT rate is 20%.

 

Work to do

  1. Calculate the product's sales price including tax, taking into account that the company wishes to maintain its usual margin.
  2. Calculate the margin rate.
  3. The Carrège company decides to sell the product at the price including tax of €490. What would be the margin thus achieved on the product?
  4. With this same selling price, what should be the proportion of its charges on purchases while preserving its usual markup rate?

 

Proposed correction

1/ Calculate the product's sales price including tax, taking into account that the company wishes to preserve its usual margin.

Calculation of fees on purchases

First, you can calculate the amount of fees on purchases with the following calculation:

Fees on purchases = 45% of the purchase price excluding VAT

Fees on purchases = €220 × 45%

Fees on purchases = 220 × 0,45

Fees on purchases = €99

The amount of the purchase fees therefore amounts to €99.

 

Calculation of purchase cost

We can now calculate the purchase cost using the purchase price and the purchase fees calculated above.

Purchase cost = Purchase price + Purchase fees

Purchase cost = €220 + €99, or a total of €319.

The purchase cost amount is therefore €319.

 

Calculation of the selling price excluding VAT

We can now calculate the selling price excluding VAT using the following formula:

PV HT = Purchase cost ÷ (1 – Markup rate)

In fact, the rate given in the statement is indeed a markup rate because it represents a percentage in relation to sales.

We can apply the formula as follows:

PV HT = 319 ÷ (1 – 20%)

PV HT = 319 ÷ 0,8

PV excluding VAT = €398,75

The sales price excluding tax of the product is therefore €398,75.

 

Calculation of the sales price including tax

We can finally answer the question posed, namely, the determination of the sales price including tax.

For this we will apply the following formula:

PV including tax = PV excluding tax × (1 + VAT rate)

So we have :

PV incl. VAT = 398,75 × (1 + 20%)

PV incl. VAT = 398,75 × 1,2

PV incl. VAT = €478,50

The product's sales price including tax is therefore €478,50.

 

2/ Calculate the margin rate.

To calculate the margin rate, simply apply the following formula:

Margin rate = [(PV HT – Purchase cost) ÷ Purchase cost] × 100

We obtain the following calculation:

[(398,75 – 319) ÷ 319] × 100 = 25%

 

3/ The Carrège company decides to sell the product at the tax-inclusive price of €490. What would be the margin thus achieved on the product?

To calculate the margin, you must have an HT base at the sales price level. We will therefore apply the following formula to transform the PV TTC into PV HT:

PV HT = PV TTC ÷ (1 + VAT rate)

With the numbers this gives us the following calculation:

PV HT = 490 ÷ (1 + 20%)

PV HT = 490 ÷ 1,20

PV excluding VAT = €408,33

We can now calculate the margin using the following formula:

Margin = PV HT – Purchase cost

With the numbers this gives us the following calculation:

Margin = 408,33 – 319

Margin = €89,33

If the Carrège company sells its product at €490 including tax, it will achieve a unit margin of €89,33.

 

4/ With this same sale price, what should be the proportion of its charges on purchases while preserving its usual markup rate?

To answer this question, you have to think "backwards."

You must calculate the margin then perform the calculations to find the new purchase cost then the requested proportion.

 

Margin Calculation

To calculate the margin, we will apply the following formula:

Margin = PV HT × Markup rate

With the encrypted elements, this gives us the following calculation:

Margin = 408,33 × 20%

Margin = €81,66

The margin, taking into account the usual markup rate, therefore amounts to €81,66.

 

Calculation of the new purchase cost

We will apply the following formula for this calculation:

Purchase cost = PV excluding tax – Margin (since Purchase cost + Margin = PV excluding tax)

With the numbers this gives:

Purchase cost = 408,33 – 81,66

Purchase cost = €326,67

The new purchase cost is therefore €326,67.

 

Calculation of the new amount of fees on purchases

Now we know that the purchase cost is made up of two elements: the purchase price and the purchase costs.

The purchase price excluding VAT remains unchanged, so it is €220. To find the amount of the purchase fees, simply subtract the purchase cost from the purchase price.

The new amount of fees on purchases therefore amounts to:

Fees on purchases = 326,67 – 220

Fees on purchases = €106,67

The purchase fees are now €106,67.

 

Calculation of the desired proportion

To find the required proportion, we will do the following calculation:

Proportion = (Purchase costs ÷ Purchase cost) × 100

Proportion = (106,67 ÷ 326,67) × 100

Proportion = 32,65%

The Carrège company must therefore reduce the proportion of its purchasing costs to 32,65% if it wishes to maintain its usual mark-up rate while selling its product at €408,33 excluding VAT (€490 including VAT).
