## Full page content

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 .
