IAPvalue

IAPvalue is a metric used in digital app analysis to quantify the monetary value of in-app purchases (IAP) for a user, cohort, or segment over a defined time horizon. It is designed to isolate the revenue contribution from IAPs from other monetization streams and engagement effects, providing a focused view of IAP-driven profitability.

Calculation and interpretation of IAPvalue vary, but typical approaches model the expected IAP revenue across future periods. A common formulation expresses IAPvalue as the discounted sum of expected IAP revenue: IAPvalue = sum over periods t of E[Revenue from IAP at time t] divided by (1 + r)^t, where r is a discount rate. In practice, analysts estimate the probability of IAP purchases in each period and the average revenue per IAP event, using cohort analysis, survival models, or probabilistic forecasting. The resulting figure helps compare monetization strategies, segments, and pricing changes focused specifically on IAPs.

Applications include evaluating the effectiveness of IAP-related pricing, item offerings, and promotional campaigns; guiding resource allocation for feature development that impacts IAPs; and informing experiments that target IAP uptake. IAPvalue is often used in conjunction with broader metrics such as lifetime value (LTV), ARPU (average revenue per user), and ARPPU (average revenue per paying user) to provide a more nuanced view of monetization.

Limitations include dependence on model assumptions about future behavior, horizon length, and discounting. Since there is no universal standard, definitions and methods for calculating IAPvalue can differ across organizations, which can affect comparability.
