Question about

Percentage of customers needed to buy the warranty in order to keep WyCar’s profit margin from model “300” stable

Can anyone guide me through this calculation please? I don't understand how the % that price reduction (€1000) represents of warranty profits (€1250)  is directly related to the % of costumers needed to keep profits stable (80%).

Thank you in advance!

Hi there,

Fair question! So, because we are losing revenue from price reduction, we need to make up for this by gaining revenue from warranty sales.

This is a classic breakeven!

So, first, create the full formula, and then pulg-in what's missing.

  1. Profit from warranty* % quantity sold = Profit loss from car
  2. (Revenue from warranty - expected cost from warranty) * quantity sold = Profit loss from car
  3. (2,350 - 1,100) * quantity sold = $1,000
  4. 1,250 * quantity sold = $1,000
  5. Quantity sold = 1,000/1,250 = 80%

Thank you very much for your answer Ian! Now it's very clear. I guess then it is just the quantity of warrants represented as a percentage (multiplied by 100). I'm used to seeing x as a percentage of y, not standing alone. So in this case I would see this % as the loss from car being 80% of profits from the warranty, so we have to compensate with 80% more sales. Is it common for quantity sold being asked as a percentage?
