COD vs Prepaid: The Unit Economics Every Founder Needs

Every percentage point you shift from COD to prepaid is gross margin — but the magnitude isn't obvious until you do the math at your scale. Here's what it looks like at ₹5 Cr, ₹25 Cr, ₹100 Cr, and ₹500 Cr.

The arithmetic is simple but most founders never sit with it. COD orders return at 25–35%. Prepaid orders return at 2–8%. Every order you convert from COD to prepaid is, statistically, an order that goes from "30% chance of becoming a loss" to "5% chance of becoming a loss".

The leverage at four scales

Assume a brand running at 30% COD RTO, 5% prepaid RTO, ₹200 all-in cost per RTO, and 60% COD share today. What does shifting 10 percentage points to prepaid (so COD share goes from 60% to 50%) save?

At ₹5 Cr / ~₹40 lakh monthly GMV

About ₹2.5 lakh saved per month on direct logistics drain. Annualised: ₹30 lakh. That's an entire team member's salary, recovered.

At ₹25 Cr / ~₹2 Cr monthly GMV

About ₹12 lakh saved per month. Annualised: ₹1.4 Cr. This is the difference between funding a marketing experiment and not.

At ₹100 Cr / ~₹8 Cr monthly GMV

About ₹50 lakh saved per month. Annualised: ₹6 Cr. At this scale, RTO mitigation is the difference between profitability and not.

At ₹500 Cr / ~₹40 Cr monthly GMV

About ₹2.5 Cr saved per month. Annualised: ₹30 Cr. At this scale, RTO is a strategic priority that gets a CEO-level metric, not an ops one.

How to actually shift the mix

Three levers, in order of impact:

Prepaid discount. A 5% discount for prepaid checkout typically lifts prepaid share 10–15 points within 90 days. The discount cost is far less than the RTO saving — at any scale above ₹10 Cr, the math is unambiguously positive.

COD fee in high-RTO pin codes. Surgical, not blanket. Identify the pin codes where COD RTO exceeds 35% and add a ₹50 COD fee there only. Most customers either prepay or are filtered out as low-intent.

Partial prepayment. ₹50–100 prepaid, balance on delivery. Acts as a commitment device — refusal rate on partial-prepaid orders drops to near-prepaid levels.

The hidden second-order effect

Every prepaid order is also a clean signal to your Meta and Google ad pixel. Every RTO is a false signal that degrades your targeting over months. So shifting to prepaid doesn't just save logistics cost — it improves the quality of every future ad rupee. The calculator models this in advanced mode.

The brands that crack ₹100 Cr without burning are almost universally the ones that addressed COD share before they hit ₹50 Cr.
