How do I factor RTO, returns, COD, shipping and discounts into my true margin?

These are the silent margin killers that live inside CM2, and in India they're brutal: COD orders can cost 50-100% more to serve, RTO on COD often runs 20-35%, and each returned order burns forward + reverse shipping, repackaging, blocked capital and wasted CAC. The honest way to model it is to spread total RTO/return cost across every order shipped, not just the ones that came back, and to net every discount and coupon off revenue before you calculate CM1. Do that and your real contribution margin usually drops several points below what your gross margin promised.
