AUA Model: How It Works

Under AUA vs fixed fee investment advisory, the AUA model calculates the fee as a percentage of portfolio value each period. If an investor's portfolio is Rs 40 lakh and the AUA rate is 1.5% annually, the annual fee is Rs 60,000. If the portfolio grows to Rs 80 lakh, the same 1.5% rate produces an annual fee of Rs 1,20,000. The fee scales directly with portfolio size. For investors with growing portfolios, the annual fee amount increases over time even if the advisory service's actual workload per rupee of assets decreases at scale.

Fixed Fee Model: How It Works

The fixed fee model in AUA vs fixed fee investment advisory charges the same rupee amount regardless of portfolio size. If the adviser charges Rs 75,000 annually, that amount is the same whether the investor's portfolio is Rs 30 lakh or Rs 1 crore. For a Rs 30 lakh portfolio, the fixed fee represents 0.25% of portfolio value — potentially lower than the AUA rate. For a Rs 30 lakh portfolio paying the same fixed fee of Rs 75,000, the effective rate is 0.25%; for a Rs 10 lakh portfolio, the same fixed fee represents 0.75% — potentially more expensive than an equivalent AUA rate.

Portfolio Value	AUA at 1.5% Annual	Fixed Fee Rs 75,000	Cost-Effective Option
Rs 20 lakh	Rs 30,000	Rs 75,000	AUA
Rs 50 lakh	Rs 75,000	Rs 75,000	Equal
Rs 1 crore	Rs 1,50,000	Rs 75,000	Fixed fee
Rs 2 crore	Rs 3,00,000	Rs 75,000	Fixed fee

SEBI Regulatory Context for Both Models

In AUA vs fixed fee investment advisory, both models are subject to SEBI's maximum fee limits specified in the June 2025 fee circular and subsequent guidance. The limits vary by client category (individual/HUF, non-individual, accredited investor). Neither model permits charging above the applicable maximum. Both models require: fee mode clearly specified in the client agreement, client consent before changing from one fee mode to another and compliance with advance fee and refund rules applicable to the client category.

How to Decide Between AUA and Fixed Fee

In the AUA vs fixed fee investment advisory comparison, the decision framework is straightforward: calculate the expected annual cost under each model at your current portfolio size, then project how that changes at anticipated future portfolio sizes. If your portfolio is large relative to the fixed fee amount offered, fixed fee is more cost-effective. If your portfolio is small relative to the fixed fee amount, AUA may be cheaper. Also consider cost predictability preferences: fixed fee provides known annual costs regardless of performance while AUA costs fluctuate with portfolio value. SEBI-registered Research Analyst platforms like Univest (SEBI RA Reg. No. INH000013776) use subscription fees that differ from IA fee models; their current pricing should be reviewed on the official website.

Conclusion

AUA vs fixed fee investment advisory is a cost-efficiency comparison that depends on portfolio size. AUA fees scale with portfolio value making fixed fees more cost-effective for larger portfolios; smaller portfolios may find AUA more affordable than a fixed fee amount that does not scale down proportionally. Both models are subject to SEBI maximum limits for the applicable client category. Investors should calculate their expected annual cost under both models at their current portfolio size before selecting a fee mode.

FAQs

What is the difference between AUA and fixed fee in investment advisory?

Ans. AUA fee charges a percentage of portfolio value, so the absolute fee amount changes with portfolio performance. Fixed fee charges a predetermined flat amount regardless of portfolio size or performance. AUA fees are cost-proportional to portfolio size; fixed fees are cost-efficient for larger portfolios because the same amount is charged regardless of whether the portfolio is Rs 50 lakh or Rs 5 crore. The AUA vs fixed fee investment advisory framework discussed here applies throughout.

Which is more cost-effective: AUA or fixed fee advisory?

Ans. Neither is universally more cost-effective. AUA is cheaper when portfolio value times the AUA percentage is less than the fixed fee amount. Fixed fee is cheaper when portfolio value times the AUA percentage exceeds the fixed fee amount. The crossover point (where both models cost the same) is the fixed fee amount divided by the AUA percentage. Calculate this crossover for the specific rates offered and compare against your portfolio size. The AUA vs fixed fee investment advisory framework discussed here applies throughout.

Can an investor switch between AUA and fixed fee advisory?

Ans. Yes, but switching between fee modes requires documented client consent. Under SEBI IA fee regulations, advisers cannot unilaterally change the fee mode; the change must be agreed upon and documented. Investors who switch fee modes should verify how the transition is handled, whether a billing adjustment is made for any already-paid fees under the previous mode and that the new mode is correctly reflected in the client agreement. The AUA vs fixed fee investment advisory framework discussed here applies throughout.

Do SEBI fee limits apply to both AUA and fixed fees?

Ans. Yes. SEBI's June 2025 fee circular and subsequent guidance specify maximum limits applicable to both AUA and fixed fee arrangements for the relevant client categories. These limits cannot be exceeded under either fee model. Investors should verify the current applicable maximum for their client category (individual/HUF, non-individual, accredited) directly from SEBI's guidance at the time of subscription. The AUA vs fixed fee investment advisory framework discussed here applies throughout.

What happens to advisory fees if my portfolio size changes significantly?

Ans. Under AUA fee investment advisory, the fee amount changes automatically with portfolio size — a larger portfolio results in a higher fee, a smaller portfolio in a lower fee. Under fixed fee, the amount stays the same regardless of portfolio size changes. If portfolio growth makes AUA fees disproportionately large relative to service value, investors can discuss switching to a fixed fee model with documented adviser consent. The fee mode and rules for changing it should be specified in the original client agreement.

Are SEBI Research Analyst subscription fees the same as Investment Adviser AUA or fixed fees?

Ans. No. SEBI Research Analyst services charge subscription fees for access to their general research, which is a different regulatory and pricing framework from SEBI Investment Adviser AUA or fixed fees. IA fee regulations with their specific ceilings apply to Investment Advisers providing personalised advice. Research Analyst subscription fees are not subject to the same ceiling framework as IA fees. Verify the registration category of any advisory service before applying IA fee framework analysis to its pricing.
