I want to add a predefined markup for all products, so that once we enter the cost, the price is automatically calculated based on that markup.

We don’t know the cost or price of the products from the beginning, so the markup will help us set prices easily once the cost is available.

For example, if we set a predefined markup of 40% for a product and later enter a cost of 10, the system should automatically calculate and set the price to 14.
