Customer Acquisition Cost Calculator

Calculate blended and paid CAC across marketing and sales investments to benchmark acquisition efficiency.

Overview & Mechanics

How the Customer Acquisition Cost Calculator Works

The Customer Acquisition Cost (CAC) Calculator measures the total capital required to persuade a customer to buy your product or service. Tracking CAC prevents businesses from scaling unprofitable growth channels.

Step-by-Step Tutorial

How to Use This Tool in Simple Steps

01

Enter total marketing expenses (paid ads, agency retainers, software tools, content).

02

Enter total sales expenses (sales salaries, commissions, demo tools, CRM).

03

Enter the total number of new customers acquired during the evaluation window.

04

Optionally specify how many customers originated organically to calculate Paid CAC versus Blended CAC.

Mathematical Logic

Formulas & Computational Methodology

Total Expenditure = Marketing Costs + Sales Costs. Blended CAC = Total Expenditure / Total New Customers Acquired. Paid CAC = Total Expenditure / (Total Customers - Organic Customers).
Case Study Scenario

Real-World Walkthrough

A SaaS company investing $28,000 in monthly marketing and $12,000 in sales rep compensation ($40,000 total) that acquires 200 new customers experiences a Blended CAC of $200 per customer. If 50 of those customers came via organic referral, their Paid CAC is $266.67.
Important Caveats

Limitations & Assumptions

  • Requires consistent time-alignment between when ad dollars were spent and when customer conversions matured.
  • Does not capture enterprise multi-touch attribution cycles spanning more than 90 days.
Common Questions

Frequently Asked Questions

Blended CAC averages cheap organic word-of-mouth users with expensive paid ad acquisitions. Relying solely on blended CAC can mask the reality that your paid ad channels are burning cash unsustainably.
