What Is Repeat Investment Rate (RIR)?

Repeat Investment Rate (RIR) measures the percentage of investors who make subsequent capital commitments after their initial investment. It reflects the durability and long-term value of an investor relationship.

Why it matters

Repeat investment is one of the clearest signals of satisfaction and confidence a firm can observe. RIR helps fund managers understand whether relationships are being nurtured well after the first commitment, connecting directly to Investor Lifetime Value.

How to calculate it

Divide the number of investors who make a second or subsequent capital commitment by the total number of investors eligible to reinvest during the measurement period, then express the result as a percentage.

What good looks like

In most cases, a higher RIR indicates strong ongoing trust and satisfaction. A stronger result may suggest that investor nurturing continues meaningfully after the initial capital commitment rather than stopping once funds are received.

Common failure mode

A common failure mode is measuring RIR without accounting for fund structure or investment cycle timing, which can make reinvestment appear low simply because investors have not yet reached a natural reinvestment window.

Relationship to other measures

RIR is a key Relationship Capital metric, indicating whether relationships deepen economically over time. It relates to Average Initial Investment Value, Investor Referral Value, and Investor Relationship Maturity Score.
