How do I calculate the true cost of offering discounts?

As an e-commerce business owner, I'm struggling to understand the real financial impact of running discount campaigns. I want to know how to calculate the true cost of discounts beyond just the percentage reduction, including factors like profit margins, customer acquisition costs, and potential long-term value. I need a comprehensive method to analyze whether my current discount strategies are actually helping or hurting my bottom line, and how to make data-driven decisions about promotional pricing.
