New Customer Total Cost %: Cost Structure Analysis

Total cost as a percentage of new customer net revenue, filtered to first-time buyers only.

Formula

New Customer Total Cost % = ( New Customer Total Cost ÷ New Customer Net Revenue ) × 100

Formula Components

Example

Your store spent 62% of new customer net revenue on total costs in Q1:

Cost Category	Amount	% of NC Revenue
COGS	$18,500	37%
Variable Costs	$6,250	12.5%
Marketing	$5,000	10%
Other	$1,250	2.5%
Total Cost	$31,000	62%

With $50,000 in new customer net revenue, 38% remains as contribution margin.

How It Works

New Customer Total Cost % sums all costs attributed to first-time buyer orders—including product costs (COGS), variable fulfillment costs, marketing spend, and overhead—then divides by net revenue. This shows how much of each new customer dollar is consumed by costs before profit.
