Fully-loaded CAC Calculator

Calculate fully-loaded CAC by including paid spend plus sales & marketing costs (salaries, tools, and other acquisition costs).

Fully-loaded CAC includes more than ad spend. It adds the costs required to acquire customers (sales & marketing salaries, tools, and other acquisition costs) to get a planning-grade CAC.

Use the same time window for costs and new customers, and keep the definition consistent over time so trends are meaningful.

How to calculate

  1. Choose a time window (month/quarter) and a segment (paid channel, motion, plan).
  2. Enter paid spend and other acquisition costs for the same window.
  3. Enter the number of new paying customers acquired in the same window.
  4. Compute fully-loaded CAC = total acquisition costs / new customers.

Formula

Fully-loaded CAC = (paid spend + salaries + tools + other) / new customers
  • All costs and new customers are measured over the same time window.
  • Salaries/tools are allocated to acquisition consistently (planning definition).
  • Use segment-level CAC (channel/plan) when possible; blended numbers can hide weak cohorts.

FAQ

Is fully-loaded CAC better than paid CAC-
They answer different questions. Paid CAC helps optimize paid channels; fully-loaded CAC is more useful for planning and unit economics because it includes the costs required to acquire customers.
Should I include support and COGS in CAC-
Typically no. CAC focuses on acquisition costs. Support/hosting are usually part of COGS and affect gross margin, which impacts payback and LTV.

Common mistakes

  • Using leads/trials as 'customers' (denominator mismatch).
  • Mixing time windows (monthly costs with quarterly customers).
  • Changing what you include month-to-month (definition drift).

How to interpret

How to use fully-loaded CAC
  • Use it for planning and unit economics (payback, LTV:CAC).
  • Keep the definition stable over time to avoid misleading trends.
  • Segment by channel and plan to find which motions are sustainable.

Quick checks

  • Keep time units consistent (monthly vs annual) across inputs and outputs.
  • Segment by cohort/channel/plan before trusting a blended average.
  • Use the related guide to avoid common definition and denominator mismatches.
