How It Works

Returning Customer Total Cost % sums all costs attributed to repeat buyer orders—including product costs (COGS), variable fulfillment costs, marketing spend, and transaction fees—then divides by net revenue. This shows how much of each returning customer dollar is consumed by costs before profit.

When to Use

Scenario	Action
Retention profitability analysis	Verify repeat buyers have lower cost % than new customers
Loyalty program ROI	Check if retention discounts inflate total cost %
Efficiency benchmarking	Compare RC cost % against NC cost % to validate retention strategy
Margin optimization	Identify cost drivers specific to repeat orders

Metric	Relationship
Returning Customer Contribution Margin	Operating profit margin (100% minus cost %)
Returning Customer Net Revenue	The denominator for this calculation
New Customer Total Cost %	Same metric for first-time buyers—compare to evaluate customer economics
Total Cost %	Blended cost % across all customers
