Compare Common Scenarios
How the numbers shift across typical situations for this calculator:
| Scenario | Annual AUM growth rate | Total AUM growth |
|---|---|---|
| $1B to $2.5B over 5yr | 20.11% | 150.00% |
| $50M to $200M over 3yr | 58.74% | 300.00% |
| $10B to $14B over 4yr | 8.78% | 40.00% |
| $500M to $350M over 2yr | -16.33% | -30.00% |
How This Calculator Works
Enter AUM at the start and end of the period, with the years between them. The calculator finds the compound annual growth rate, the steady yearly pace that connects the two snapshots.
The Formula
Compound Annual Growth Rate
Start is the beginning value, End is the ending value, n is the number of years
Worked Example
A fund growing from $1B to $2.5B over 5 years posts a 20.1% annual AUM growth rate. Total growth is 150%, but the annual figure is what compares against industry benchmarks and against the underlying market return. Growth above market suggests strong net new flows; growth below market implies redemptions.
Key Insight
AUM growth has two engines: market appreciation (the underlying portfolio rising) and net flows (new money in minus redemptions). Decomposing the two reveals whether the firm is actually winning customers or just riding the market. A flat market with rising AUM is a strong sign; a rising market masking flat AUM is a warning.

AUM GROWTH COMPONENTS.
Market appreciation (passive).
Net flows (inflows − outflows).
Organic growth = net flows (more valuable).
Decompose for true business health.
FEE REVENUE LINK.
Management fee = fee % × AUM.
AUM growth drives revenue.
Equity ~0.50-1.0%, bond ~0.30-0.50%, passive ~0.03-0.20%.
FEE COMPRESSION.
Passive/ETF pressure (Vanguard effect).
Active-fund fees declining.
Breakpoints (large AUM = lower %).
MIX SHIFT.
Equity (higher fee) vs fixed income (lower).
Alternatives (higher fee) vs passive.
Mix affects revenue per AUM dollar.
Fee structures + valuation + risk
FEE STRUCTURES.
Mutual fund/ETF: management fee (% AUM).
Hedge fund: 2-and-20 (2% mgmt + 20% performance).
PE: 2% + 20% carry over hurdle.
Performance fees add volatility.
VALUATION.
Asset managers valued on AUM + fee rate + growth.
Organic flows premium to market beta.
Sticky AUM (retirement, institutional) premium.
FLOW STABILITY.
Redemption terms + lockups.
Institutional vs retail stickiness.
Performance-driven flows (volatile).
RISKS.
Market downturn (AUM + fee revenue drop).
Outflows (underperformance, fee competition).
Fee compression structural.
Key-person risk (star managers).
STRATEGY (analysis).
Separate organic from market.
Track net flows + fee rate trends.

Frequently Asked Questions
What is AUM?
Assets under management — the total market value of the assets a fund or asset manager oversees. Management fees are typically charged as a percentage of AUM, making AUM growth the most direct driver of revenue.
What drives AUM growth?
Two factors: market appreciation of the existing portfolio and net new flows (new client deposits minus redemptions). Decomposing the two shows whether the firm is winning customers or coasting on market returns.
Why use the annualized rate?
Total growth depends on the window. Annualizing it lets you compare across periods, against market benchmarks, and against industry peers on equal footing.
What is a healthy AUM growth rate?
Top-quartile active managers in growing categories can post 15%+ annualized AUM growth; passive index funds often grow 10% to 25% during bull markets. Below market return for a sustained period signals net outflows.
How is this different from fund returns?
Fund returns measure portfolio performance — what existing money earned. AUM growth measures the size of the pool, which includes flows from new investors. A great fund with no marketing can post strong returns but flat AUM.
When is this calculator unreliable?
Less reliable when market appreciation vs net flows decomposition (organic growth more valuable), when management fee compression (ETF/passive pressure), when fee tiers + breakpoints (large AUM lower %), when performance fees (hedge funds 2-and-20), when gross vs net flows, when AUM mix shift (equity vs fixed income fee rates), when seed/founder capital vs third-party, or when redemption/lockup terms affecting flow stability.

Methodology & Review
Fund AUM growth rate = (Ending AUM − Beginning AUM) / Beginning AUM × 100, or CAGR for multi-year. AUM growth = market appreciation + net flows (inflows − outflows). U.S. 2024: AUM growth drives fund-manager fee revenue (management fee % × AUM); distinguishing organic flows from market return is key for valuation. RELIABILITY: Reliable for growth-rate math. Less reliable for (a) market appreciation vs net flows decomposition (organic growth more valuable), (b) management fee compression (ETF/passive pressure), (c) fee tiers + breakpoints (large AUM lower %), (d) performance fees (hedge funds 2-and-20), (e) gross vs net flows, (f) AUM mix shift (equity vs fixed income fee rates), (g) seed/founder capital vs third-party, (h) redemption/lockup terms affecting flow stability.
