Asset manager organic base fee growth measures growth in recurring base-fee economics generated by net new asset flows under the manager's disclosed methodology.

It is an organic fee-growth measure, not total revenue growth and not AUM market appreciation.

BlackRock reported 10% last-twelve-month organic base fee growth in its second-quarter 2026 results.

Fee growth can differ from asset growth

BlackRock defines its last-twelve-month organic base fee growth rate using net new base fees earned on net asset inflows relative to the beginning base-fee run rate.

That means the fee mix of new flows matters.

Do not substitute market appreciation

Rising markets can increase AUM and reported fee revenue without representing organic base-fee growth. The metric is intended to isolate the economics attached to net new client assets.

Primary source

Asset manager organic base fee growth is most useful as an organic fee-growth measure. Read it with net flows, organic asset growth, AUM mix, and reported base fees.

Part of the Asset Management Operating Model

Connect managed-asset scale, flow quality, fee-bearing assets, recurring and performance fees, and fee-related profitability to understand asset-manager economics.

How the model fits together
  • Asset-base growth: Ending AUM reflects beginning assets plus client net flows, market movement, foreign-exchange effects, distributions, acquisitions, and other scope changes. Net flows therefore isolate client asset movement from market-driven changes in the managed-asset base.
  • Fee-base monetization: Average AUM and fee-earning AUM identify the period-matched and contract-eligible asset bases behind recurring fees. Effective fee rates, investment advisory fees, and organic base-fee growth connect those asset bases to reported recurring revenue economics.
  • Flow mix and fee profitability: Long-term and cash-management flows reveal where organic asset growth is coming from, while performance fees and fee related earnings separate variable monetization from recurring fee-driven profitability.
