What Do CM1, CM2 and CM3 Mean in D2C Unit Economics?
Posted by Admin on 7/30/2026
Most D2C founders talk about margin as a single number. The brands that actually control profitability break it into three layers, because each layer tells you about a different problem.
CM1: gross product margin. Revenue less cost of goods sold. This is what is left after you pay for the product itself. If CM1 is weak, you have a sourcing or pricing problem, and no amount of marketing cleverness fixes it.
CM2: post fulfilment margin. CM1 less the costs of getting the order to the customer, meaning shipping, packaging, payment gateway charges, and critically RTO and return costs. CM2 is where Indian D2C brands are quietly bleeding, because RTO rarely appears as a line item founders watch, yet it can erase the profit on several delivered orders with a single failed one.
CM3: post marketing margin. CM2 less marketing and acquisition cost. This is the number that finally tells you whether an order made money. A brand can have healthy CM1 and CM2 and still run negative CM3 because it is overpaying to acquire customers.
Why the layers matter more than one blended margin. The three numbers are a diagnostic. Weak CM1 points to sourcing or pricing. Healthy CM1 with weak CM2 points to operations, usually RTO or shipping cost. Healthy CM2 with negative CM3 points to acquisition efficiency. The symptom looks identical from the outside, meaning the brand is not making money, but the fix is completely different in each case. Collapse everything into one margin figure and you cannot tell which fire you are fighting.
Which of your three contribution margin layers is weakest right now, and do you track them separately or as one number?
