Example
Your store spent 48% of returning customer net revenue on total costs in Q1:
| Cost Category | Amount | % of RC Revenue |
|---|
| COGS | $37,500 | 30% |
| Variable Costs | $11,250 | 9% |
| Marketing | $7,500 | 6% |
| Other | $3,750 | 3% |
| Total Cost | $60,000 | 48% |
With $125,000 in returning customer net revenue, 52% remains as operating profit margin.
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.

| 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 |
