CAC Calculator accuracy and testing
This page documents how Calwarden builds trust for this calculator: source notes, regression-style default tests, limitations, assumptions, unit handling, rounding, and visible change history.
Formula source
- CAC = Total Sales & Marketing Costs / New Customers Acquired.
Test cases
Default input regression check
Generated from the checked-in default inputs and calculate function.
Inputs
- Total Sales & Marketing Costs: $5,000
- New Customers: 100
Expected outputs
- CAC: $50.00
Known limitations
- This page documents the checked-in calculator logic and does not certify results for every real-world edge case.
- Use the result as a planning estimate unless the calculator page states a stricter purpose.
Assumptions
- Spend and new-customer counts should cover the same reporting period.
- This model treats every acquired customer equally; it does not separate channel quality or retention differences.
- If no new customers were acquired, CAC is undefined rather than zero.
Unit handling
- Total Sales & Marketing Costs accepts values in $.
- New Customers accepts numeric values.
- CAC is displayed as currency.
Rounding rules
- Number displays use up to 2 decimal places in the calculator UI.
- Currency outputs are displayed with standard US dollar formatting.
