Is there amy general rule like 15% first year and then 20 and so on?

My cosuins 3 month old laptop is being planned for sale so how much can we expect with the specs as below:

Directly proportional to the frequency the vendor discounts them. If there are frequent promos then your selling price goes down because you are in effect competing with vendor.

Apple does not do this and this is the primary reason apple products face less depreciation

For everybody else its a numbers game. They have sales targets to reach at regular intervals.
