Formula used
Blended CAC = total included sales and marketing acquisition spend ÷ all new customers.
Payback months = CAC ÷ (monthly revenue per customer × gross margin).
Currency changes formatting only, not exchange rates. Keep spend, customers, and revenue aligned to the same period and attribution scope.
Match acquisition spend with new customers from the same scope, calculate blended or paid-only CAC, and inspect gross-margin payback plus a target scenario.
Make customer acquisition cost comparable and complete
Customer acquisition cost is the average amount spent to acquire one new customer during a defined period. The arithmetic is simple, but the result depends on which costs and customers are included. A narrow paid-media CAC answers a different question from fully loaded blended CAC.
Paid-only CAC pairs paid media and paid-campaign execution costs with customers attributed to paid acquisition. Blended CAC pairs broader sales and marketing acquisition spend—including people, partners, tools, and content—with all new customers. Neither number is meaningful when costs and customer cohorts use different dates or attribution scopes.
Paid-only CAC
Use paid media and paid-campaign costs with paid-attributed new customers.
Blended CAC
Use fully loaded acquisition spend with all new customers across channels.
Margin-based payback
Estimate recovery time using monthly revenue per customer after gross margin.
Target scenario
See the spend reduction or extra customers required to meet your own target CAC.
How it works
Build a CAC calculation
you can audit
Every result retains the selected scope, included costs, customer count, and formula.
Choose paid or blended
Select the acquisition question before entering spend or customer attribution.
Add aligned costs and customers
Use the same reporting period and include costs that belong to the chosen scope.
Review CAC and recovery
Inspect spend mix, per-customer cost, gross-margin payback, and your target gap.
What to include in a defensible CAC
Consistency matters more than forcing the result toward a generic benchmark.
Paid media
Include campaign spend across the networks and placements used to acquire the attributed customers.
People costs
For blended CAC, include salary, benefits, commissions, and relevant sales and marketing labor.
Agencies and tools
Include contractors, platforms, data, software, and services used in the acquisition process.
Content and events
Include creative production, content, sponsorships, events, and programs attributable to acquisition.
New customers only
Keep leads, signups, reactivations, expansions, and renewals out unless the metric is explicitly redefined.
Aligned attribution window
Match spend and customer acquisition using consistent dates, lag assumptions, and channel attribution rules.
