Common CAC Calculation Mistakes

Common CAC Calculation Mistakes

Incomplete Cost Attribution

Partial cost attribution is the case when a firm does not cover all of its costs to acquire a new customer. By ignoring these costs you artificially decrease CAC which can mislead your budgeting and strategy.

Missing Costs

Missing costs are any of the acquisition-related costs you forgot to account for in your CAC calculation:

• Not accounting internal team time and salaries: The hours your sales, marketing, and support staff dedicate towards campaigns equal real salary costs — these should be added to CAC.
• Forgetting about tool and platform fees: Email services, CRM platforms, ad networks, and analytics tools all have subscription fees which factor into acquisition costs.
• Creative development and content creation costs not included: Design, copywriting, video production, and similar content creation efforts mean agency fees or use of internal resources.
• Over-looking overhead & indirect costs: To include office rent, utilities, depreciation on equipment and shared services (HR and finance support) should be spread across customer acquisition.

Incorrect Time Attribution

Misinformation from misattribution of time Simply put, misattributing the time that expenses and acquisitions occurred can lead to misinformation in CAC metrics:

• Blurring acquisition and retention costs: Track campaigns with retention percentages independently, otherwise they boost CAC.
• Comparing Q1 marketing spend to Q2 new customers skews the ratio. Averages suck here, and should not be used over inconsistent time periods. Keep spend and customer counts aligned over the same time period.
• You're not Subscription business model. If you aren't matching costs with the same customer acquisition: - You ran a June campaign but identified customers in July—Determine the correct cut-off or switch to rolling CAC.
• Incorporating one-off setup costs in CAC ongoing calculations: The initial set-up such as an original branding, a website build or a CRM shouldn't be considered when you include these expenses in the overall cost of customer acquisition.

Attribution and Tracking Errors

Attribution and tracking mistakes occur when conversions are misallocated or completely missed. This misapportions what channels are actually responsible for new customer acquisition.

Technical Tracking Issues

Technical tracking issues are simply flaws in execution that can lead to either incomplete or undesired data:

• Incomplete tracking conversion configuration: If you didn't correctly install tracking pixels, tags or seismic server-side analytics; it can leave massive leaks in the data.
• Lost cross-device and cross-platform attribution: Leads regularly engage across mobile, desktop, in-store — failing to connect them (stitching) results in underreporting.
• Not mapping offline conversions: If you want to tie a phone call, in-store visit, or mailed coupon back to the ad that drove them there, you need call-tracking numbers, POS integrations, unique codes – otherwise you won't know their impact on CAC.
• Poor data stitching between marketing channels: Unsynchronized processes (e.g., ad platforms, email service providers, affiliate networks) need to consolidate into a common single source of truth or an attribution model.

Analytical Errors

Analytical errors develop when the selected models or methods to process data distort the true value of every channel:

• Utilizing the wrong attribution models: Lean too heavily on last-touch and you over-credit one channel; using only first touch may miss out on any nurturing you do. Multi-touch or algorithmic models tend to deliver a more nuanced perspective.
• Forgetting about organic lift: Brand searches, word-of-mouth referrals, and PR efforts have an indirect manner of driving more conversions — but can be overlooked in direct-response-only analysis.
• Assisted conversions are a must: Early engagements often have downstream influence on future purchases so by only crediting your assists you're underestimating the customer journey.
• Not excluding fraudulent or low-quality acquisitions: Ad fraud, bot traffic and incentivized clicks grow acquisition numbers with no actual consumer value, distorting CAC down.
