This is not aimed specifically at you, but at everyone who asks a question like this and relates the value of the parts/parts/components to the purchase price.
Hand on heart, if you work several hundred or several thousand hours for something and do a good job, do you want to be paid appropriately or do you work for free?
Unfortunately, it is very common to have no appreciation for the development of devices, which always amazes me. Because none of these devices would exist without development work.
The development work is a very cost-intensive part of the calculation, and if it is not paid for, there will be no future devices and the manufacturer will no longer exist. The manufacturer also bears the entire risk of the development, because not every development is successful and not every device covers the costs incurred. The lower the number of units, the higher the proportionate development costs per device.
A second point is that most people have no idea how much, or how little, of their money goes to the manufacturer. For devices sold through normal retailers or sales platforms, it is between 25 and 50%, but closer to less than 40%. In direct sales it is around 70-75%, but do not underestimate the effort and costs of direct sales. But in principle, whenever there is a sales partner or a foreign branch, the revenue per device for the manufacturer is significantly reduced.
The third point concerns the guarantee and service after purchase. This also has to be financed by the sale of each device, from the money that reaches the manufacturer. The costs for this are in the 1-2 digit percentage range and most manufacturers have to make provisions for this every year.
