Gaming IAP and Ads Calculator
Model one gaming cohort from Day 0 through D365 using your own acquisition, retention and monetization assumptions.
Start here
Estimate in-app purchase and ad receipts for a hybrid gaming cohort from your own CPI, retention and ARPDAU assumptions.
- Enter cohort ad spend, CPI, total ARPDAU, IAP share and your Day 1, Day 7 and Day 30 retention assumptions.
- Set IAP commission and the daily retention decline after Day 30, choose a reporting horizon and enter a comparison CPI.
- Calculate the cohort forecast, compare CPI scenarios and export the daily model as CSV.
Use your own observed numbers. Starting values are examples, not benchmarks.
ARPDAU includes nonpayers in its daily active user denominator. Enter total ad and IAP receipts per daily active user; commission applies only to IAP receipts. These are your assumptions, not benchmarks.
Your assumptions
Use one currency throughout. IAP ARPDAU is before the commission entered below; ad ARPDAU is publisher receipts after network fees. All installs in this simplified cohort occur on Day 0.
Your results
Receipts per install by inclusive horizon
D30 — · D90 — · D365 —
Receipts are after entered IAP commission. Receipts minus ads excludes other costs and is not profit.
Compare CPI scenarios
The comparison holds cohort budget and monetization assumptions constant; only CPI changes. User quality is not predicted.
| Scenario | CPI | Installs | Receipts | Receipts minus ads | ROAS | Payback |

How this calculator works
Enter your own observed CPI, retention, total ARPDAU and IAP share. The calculator projects one acquisition cohort and does not use industry benchmarks.
Day 0 is modeled at 100% active. The retention curve uses linear interpolation between your D1, D7 and D30 assumptions. After D30 it applies your entered daily retention decline. Daily receipts equal active fraction times ARPDAU, with the applicable IAP commission deducted.
D30, D90 and D365 include Day 0 and the named final day. The CPI comparison holds acquisition budget constant and changes inferred installs. Receipts minus ad spend excludes refunds, taxes, operating costs and other expenses; it is not profit.

Frequently asked questions
How are hybrid IAP and ad receipts split?
Your IAP share splits total ARPDAU. The entered commission applies to IAP receipts only; ad receipts remain publisher receipts after network fees.
What is IAP ARPDAU’s denominator?
ARPDAU is revenue per daily active user, including nonpayers in the denominator.
How is retention projected?
The model interpolates your D1, D7 and D30 anchors, then applies your entered daily decline after D30.
