New research from W3i claims that 47% of in-app purchase revenues for mobile games come from $9.99-$19.99 transactions rather than smaller amounts.

This is based on an analysis of purchases made by 66m monthly active users from games using the company’s monetisation tools on iOS and Android. It also claims that in-app purchases of between $0.99 and $1.99 only account for 6% of overall IAP revenues for these games.

Actually, this shouldn’t come as a surprise for the mobile games industry, if it remembers some data published in 2011 by Flurry.

Back then, it claimed that $10-$20 IAP accounted for 16% of transactions and 18% of revenues, but that IAP of over $20 accounted for 13% of transactions and 51% of revenues – so even more whale-like behaviour than is indicated in the new W3i study.

It’s a reminder to developers that while small IAP remains an important part of freemium gaming, the higher sums – when handled properly for content that feels worth that amount of money, of course – can be where they make more of their revenues.
