Physical Product Customer Acquisition Cost Estimator
This estimator calculates the average marketing and sales cost required to acquire one new customer for a physical-product business.

CAC = (Marketing spend + Sales and creative costs) ÷ New customers acquired
All costs and customer counts must cover the same period. The result is a blended acquisition cost; channel-level CAC requires separate cost and customer totals for each channel.
What the result means
The result is the average amount spent to add one new physical-product customer during the selected period.
Attribution gaps, organic demand, returns, and future repeat purchases can change the business value of this figure.
Given
A cookware brand spends $12,000 on ads and $3,000 on campaign production, acquiring 600 new customers.
Calculation
Total acquisition spend = $12,000 + $3,000 = $15,000.
CAC = $15,000 ÷ 600 = $25.00.
Result
The blended customer acquisition cost is $25.00 per new customer.
Should product cost be included in CAC?
No. Product cost belongs in gross or contribution margin. CAC focuses on the spending used to acquire customers.
Can I calculate CAC for one ad channel?
Yes. Enter only that channel’s attributable costs and the new customers credited to it for the same dates.
What if some buyers would have purchased without advertising?
Blended CAC will not isolate incrementality. A controlled test or lift study is needed to estimate customers caused specifically by the campaign.
Why should repeat customers be excluded?
CAC measures the cost of gaining new customers. Costs aimed at retention can be tracked separately.
How is CAC different from cost per order?
Cost per order counts all orders, including repeat purchases. CAC divides acquisition spending by newly acquired customers.
