Calculate your Assets Under Management (AUM) with our professional tool

Comprehensive Guide: How to Calculate Assets Under Management (AUM)

Assets Under Management (AUM) is a critical metric for investment firms, financial advisors, and asset managers. It represents the total market value of investments that a financial institution or individual manages on behalf of clients. Understanding how to calculate AUM accurately is essential for financial reporting, performance evaluation, and business growth strategies.

What is Assets Under Management (AUM)?

AUM refers to the total market value of all assets that an investment company or financial institution manages for its clients. This includes:

• Equities (stocks)
• Fixed income securities (bonds)
• Cash and cash equivalents
• Alternative investments (private equity, hedge funds, real estate)
• Other financial instruments

AUM is typically calculated daily, weekly, or monthly depending on the firm’s reporting requirements and the volatility of the assets being managed.

The Importance of AUM in Financial Services

AUM serves several crucial functions in the financial industry:

1. Performance Measurement: AUM growth over time indicates the firm’s ability to attract and retain clients.
2. Revenue Calculation: Most asset managers charge fees based on a percentage of AUM.
3. Investor Confidence: Higher AUM often signals credibility and success to potential clients.
4. Regulatory Compliance: Many financial regulations use AUM thresholds to determine reporting requirements.
5. Benchmarking: Firms compare their AUM growth against competitors and industry averages.

Step-by-Step Guide to Calculating AUM

1. Identify All Managed Assets

The first step in calculating AUM is to identify all assets under your management. This includes:

• Client portfolios (individual and institutional)
• Discretionary accounts where you have full investment authority
• Non-discretionary accounts where you provide advice but clients make final decisions
• Collective investment vehicles (mutual funds, ETFs) that you manage

2. Determine the Market Value of Each Asset

For each asset in your management, determine its current market value. This involves:

• Using closing prices for publicly traded securities
• Obtaining fair value assessments for private investments
• Including accrued interest for fixed income securities
• Valuing cash at its nominal amount

3. Sum All Asset Values

Add up the market values of all assets across all client accounts. The basic formula is:

Total AUM = Σ (Quantity of Asset × Current Market Price)

For example, if you manage:

• 10,000 shares of Stock A at $50 per share = $500,000
• 5,000 shares of Stock B at $100 per share = $500,000
• $200,000 in bonds
• $300,000 in cash equivalents

Your total AUM would be $1,500,000.

4. Consider Leverage (If Applicable)

Some investment strategies use leverage to amplify returns. When calculating AUM:

• Include the notional value of leveraged positions
• Disclose leverage ratios in your reporting
• Be aware that regulatory bodies may have specific rules about including leveraged assets in AUM calculations

5. Exclude Certain Assets

Not all assets should be included in AUM calculations. Typically excluded are:

• Assets where you provide only incidental advice
• Propietary assets (your firm’s own investments)
• Assets managed by sub-advisors where you don’t have discretion
• Certain alternative investments that don’t meet liquidity requirements

AUM Calculation Methods by Asset Class

Asset Class	Valuation Method	Frequency	Challenges
Public Equities	Market closing prices	Daily	Volatility, after-hours trading
Fixed Income	Market prices or yield calculations	Daily	Liquidity issues for some bonds
Cash & Equivalents	Nominal value	Daily	Minimal, but currency fluctuations for foreign cash
Private Equity	Fair value assessments	Quarterly	Subjective valuations, illiquidity
Real Estate	Appraisals or comparable sales	Quarterly/Annually	Infrequent transactions, market lag
Hedge Funds	Net asset value (NAV)	Monthly/Quarterly	Complex strategies, leverage effects

Common Mistakes in AUM Calculation

Avoid these pitfalls when calculating your AUM:

1. Double Counting: Including the same asset in multiple accounts or funds.
2. Incorrect Valuation: Using stale prices or incorrect valuation methods for illiquid assets.
3. Inconsistent Timing: Mixing valuation dates across different asset classes.
4. Overlooking Fees: Not properly accounting for management fees that reduce AUM.
5. Ignoring Leverage: Forgetting to include leveraged positions or incorrectly calculating their value.
6. Regulatory Non-Compliance: Not following specific guidelines from bodies like the SEC or FINRA.

How AUM Affects Investment Management Fees

The most common fee structure in asset management is based on a percentage of AUM. Typical fee structures include:

AUM Range	Typical Management Fee	Typical Performance Fee	Common Client Type
< $1M	1.5% – 2.0%	15% – 20%	Retail investors
$1M – $10M	1.0% – 1.5%	15% – 20%	High net worth individuals
$10M – $100M	0.75% – 1.25%	10% – 20%	Institutional, family offices
$100M – $1B	0.50% – 1.0%	10% – 15%	Large institutions, pension funds
> $1B	0.25% – 0.75%	5% – 10%	Sovereign wealth funds, endowments

Note that performance fees (also called incentive fees) are typically calculated as a percentage of profits above a certain benchmark or hurdle rate, not as a percentage of total AUM.

AUM Growth Strategies for Asset Managers

Increasing your AUM is crucial for business growth. Effective strategies include:

• Performance: Consistently delivering strong risk-adjusted returns is the most reliable way to attract and retain clients.
• Client Acquisition: Targeted marketing to high-net-worth individuals and institutional investors.
• Product Expansion: Offering new investment products or strategies to existing clients.
• Geographic Expansion: Entering new markets where demand for your expertise exists.
• Mergers & Acquisitions: Acquiring other firms to instantly boost AUM.
• Technology Adoption: Using digital platforms to attract tech-savvy investors.
• Thought Leadership: Publishing research and insights to establish credibility.

2. Gross vs. Net AUM

Firms may report different figures:

• Gross AUM: Total assets before deducting fees
• Net AUM: Assets after deducting management fees

3. Leveraged AUM Calculations

For funds using leverage, consider:

• Gross Exposure: Sum of long and short positions
• Net Exposure: Difference between long and short positions
• Leverage Ratio: Gross exposure divided by net assets

4. Currency Adjustments

For global portfolios:

• Convert all assets to a single reporting currency
• Disclose currency hedging strategies
• Consider using constant currency calculations for performance reporting

Common AUM Calculation Scenarios

Scenario 1: Retail Investment Advisory Firm

Situation: A firm with 200 clients, average account size $250,000, managing primarily equities and fixed income.

AUM Calculation: 200 clients × $250,000 = $50,000,000

Considerations:

• Daily valuation using market closing prices
• Monthly performance reporting to clients
• Quarterly regulatory filings

Scenario 2: Hedge Fund

Situation: A hedge fund with $500M in capital, using 2:1 leverage, investing in global equities.

AUM Calculation: $500M (capital) × 2 (leverage) = $1B gross exposure

Considerations:

• Daily valuation with mark-to-market accounting
• Complex derivative positions requiring specialized valuation
• Performance fees calculated on profits above hurdle rate

Scenario 3: Private Equity Firm

Situation: A firm with $2B in committed capital across three funds, with varying stages of deployment.

AUM Calculation: Sum of:

• $800M in Fund I (fully invested, valued at cost plus write-ups)
• $600M in Fund II (70% invested, remaining commitments at face value)
• $600M in Fund III (new fund, no investments yet – not included in AUM)

Total AUM = $1.26B (only invested capital and called commitments)
