Returning Customer CM4 per Order: Repeat Order Operating Profit

RC CM4 per Order is what an average repeat order leaves after product, fulfillment, payment, all ad spend, and every per-order fee you’ve configured. It doesn’t include recurring expenses or variable costs, so treat it as unit economics, not a share of overhead.

Formula

RC CM4 per Order = ( RC CM2 − RC Marketing order fees − Total Ad Spend − RC Agency Fees order fees − RC Opex order fees − RC Other order fees ) ÷ Returning Customer Orders

Formula Components

Metric	Definition
RC CM2	Repeat-order margin after COGS, fulfillment, and payment fees
RC order fees (Marketing, Agency Fees, Opex, Other)	Order fees in those categories, on repeat orders only
Ad Spend	Total spend across connected ad platforms, not split by customer type
Returning Customer Orders	Number of returning customer orders in the range

How It Works

The numerator uses costs stored on returning customer orders plus your total ad spend. NC CM4 per Order subtracts the same full ad spend, so neither segment gets a lighter share of it.

Recurring expenses and Variable costs are not subtracted. They only reach the dollar RC CM4, which carries the returning customer share of them. So RC CM4 per Order is usually higher than RC CM4 ÷ returning customer orders.

When to Use

Scenario	Action
LTV calculations	RC CM4 per Order × expected repeat orders = repeat-order margin over a lifetime
Comparing segments	Benchmark against NC CM4 per Order
Retention investment	Set loyalty program budget against RC CM4 per Order

Metric	Relationship
RC CM4	Dollar version, including the returning customer share of recurring costs
RC CM3 per Order	Before agency, opex, and other order fees
NC CM4 per Order	Same calculation for first orders
LTV	Total customer lifetime value
