How do I calculate shipping discount impact on margins?

As an e-commerce business owner, I'm struggling to understand how offering free or discounted shipping affects my overall profit margins. I want to make shipping promotions attractive to customers without cutting too deeply into my bottom line. I need a clear, mathematical approach to calculating the true impact of shipping discounts, considering factors like product costs, shipping expenses, and potential conversion rate improvements. What strategies can help me balance customer attraction with maintaining healthy profit margins?
