How do I calculate the actual profit impact of my discount campaigns?

As an e-commerce manager, I'm struggling to understand the true financial implications of my discount campaigns. While I can see total sales and discount amounts, I'm unsure how to accurately calculate the real profit impact. I need a systematic method to evaluate whether my promotions are genuinely contributing to profitability or just eroding margins. I want to understand not just the top-line revenue, but the net profit contribution of each discount campaign.
