What Is Cost of Acquiring Capital (CACa)?
Cost of Acquiring Capital (CACa)
Total investor acquisition cost divided by capital acquired.
Cost of Acquiring Capital (CACa) measures the total investor acquisition expense, including marketing, sales, and infrastructure costs, divided by the amount of capital ultimately committed. It expresses acquisition efficiency in a single economic figure that leadership can track over time.
Why it matters
CACa translates acquisition activity into a return-on-investment question. Fund managers who understand CACa can decide with confidence whether to expand a channel, restructure a team, or invest in better investor acquisition infrastructure, because every acquisition decision is ultimately a capital allocation decision.
How to calculate it
Add all direct and allocated costs associated with acquiring investors over a defined period, including marketing spend, sales compensation, technology, and content production, then divide that total by the capital actually committed during the same period.
What good looks like
In most cases, a lower CACa relative to the capital raised suggests a healthier acquisition system, though the appropriate figure varies by strategy, investor type, and check size. A stronger result may suggest that investor acquisition infrastructure and investor journey design are working together efficiently rather than in isolation.
Common failure mode
A common failure mode is measuring CACa only at the campaign level without accounting for the full cost of sales follow-up, due diligence support, and relationship nurturing, which understates true cost and leads to overconfident expansion decisions.
Relationship to other measures
CACa sits at the center of Capital Efficiency, the Acquisition Capital Indicator concerned with translating acquisition activity into economic outcomes. It is closely related to Investor Conversion to Capital Rate, Time to Capital Commitment, and Average Initial Investment Value, all of which influence the denominator and numerator of the CACa calculation.
