A Portfolio Management Services (PMS) report can show several performance figures, TWRR, XIRR, benchmark return, one-year return, since-inception return and net performance. These numbers are related, but they do not answer exactly the same question. A return measure that shows how the investment approach performed may differ from the return actually experienced by an investor who added or withdrew money during the period.
Understanding how PMS returns are calculated helps investors compare strategies more meaningfully and avoid judging performance from a single percentage. This guide explains the main return methods used in PMS, how cash flows and fees affect the calculation, how SEBI requires performance to be reported, and what investors should examine beyond headline returns.
What Is PMS and How Does a PMS Portfolio Work?
Portfolio Management Services is a SEBI-regulated investment service in which a portfolio manager manages securities or funds on behalf of a client under an agreed investment mandate.
In a discretionary PMS, the manager makes investment decisions for the client within the stated investment approach. Unlike a mutual fund, where investors own units of a pooled scheme, a PMS portfolio is maintained at the individual client level.
The value of a PMS portfolio can change because of:
- Changes in the market value of securities
- Dividends, interest or other income
- Purchases and sales within the portfolio
- Investor additions or withdrawals
- Portfolio management fees and other expenses
- Taxes and statutory transaction charges
Because several factors can change portfolio value, simply comparing the opening and closing balance may not provide an accurate picture of investment performance.
How Are PMS Returns Calculated?
For regulatory performance reporting in India, Time-Weighted Rate of Return (TWRR) is particularly important.
Under SEBI's current framework, portfolio managers must present the TWRR of an Investment Approach when communicating its performance, along with the trailing return of the selected benchmark. SEBI also requires performance data reported by portfolio managers to include cash holdings and liquid-fund investments and to be reported net of all fees and expenses, including applicable taxes.
For individual investors, another measure matters: Extended Internal Rate of Return (XIRR). SEBI requires portfolio managers to present XIRR for each Investment Approach in which an investor participates when reporting performance to that investor. The TWRR of the Investment Approach and its benchmark are shown separately.
The distinction is important:
- TWRR measures the performance of the investment approach while reducing the effect of investor-controlled cash flows.
- XIRR reflects the investor's actual return based on the amount and timing of investments and withdrawals.
PMS Return Calculation: A Simple Example to Understand
Consider an investor who starts with a PMS portfolio worth ₹50 lakh.
Assume:
- Beginning portfolio value: ₹50 lakh
- Value after one year: ₹57.5 lakh
- No additional investment
- No withdrawal during the year
The simple return is:
Return = (Ending Value − Beginning Value) ÷ Beginning Value × 100
So:
(₹57.5 lakh − ₹50 lakh) ÷ ₹50 lakh × 100 = 15%
The portfolio has generated a 15% return over the year.
If ₹57.5 lakh is the portfolio value after all applicable PMS fees and expenses, this represents the investor's net portfolio outcome before considering personal income-tax obligations.
This simple calculation works because there were no external cash flows. Once money is added or withdrawn during the period, methods such as TWRR and XIRR become more useful.

Different Methods Used to Measure PMS Returns
Investors may encounter several return measures in PMS reports and performance discussions.
| Return Method | What It Measures | When It Is Useful |
|---|---|---|
| Absolute Return | Total percentage gain or loss over a period | Short periods or simple start-to-end comparisons |
| CAGR | Annualised compound growth between beginning and ending values | Comparing multi-year performance without irregular cash flows |
| TWRR | Portfolio performance after neutralising the effect of external cash-flow timing | Evaluating the investment approach or portfolio manager |
| XIRR | Investor return accounting for the exact dates and amounts of cash flows | Measuring an individual investor's experience |
Absolute Return
Absolute return measures the percentage change between the initial investment and final value.
It does not automatically adjust for the length of the investment period. A 30% return over one year and a 30% return over four years therefore mean very different things.
CAGR
Compound Annual Growth Rate (CAGR) converts multi-year growth into an annualised rate.
For example, if ₹50 lakh grows to ₹75 lakh over several years without intermediate cash flows, CAGR helps express that growth as an equivalent annual compound rate.
However, CAGR becomes less useful when the investor repeatedly adds or withdraws capital because it does not account for the timing of those individual cash flows.
TWRR
TWRR separates the investment period into sub-periods whenever an external cash flow occurs and measures performance across those periods.
This reduces the effect of decisions that are outside the portfolio manager's control, such as an investor adding ₹20 lakh shortly before a market rise or withdrawing money before a decline.
That is why TWRR is particularly useful for comparing the performance of PMS investment approaches.
XIRR
XIRR is a money-weighted return measure. It considers:
- How much money was invested
- When each investment was made
- When withdrawals occurred
- The final portfolio value
It therefore provides a better picture of the return experienced by an individual investor when cash flows occur on different dates.
How Are PMS Returns Calculated When You Add or Withdraw Money?
Adding or withdrawing money can make a simple return calculation misleading.
Suppose an investor starts with ₹50 lakh and later adds another ₹10 lakh. If the portfolio ends the year at ₹66 lakh, it would be incorrect to treat the entire ₹16 lakh difference between the opening and closing values as investment profit because ₹10 lakh came from the investor.
This is where TWRR and XIRR serve different purposes.
TWRR Separates Investment Performance From Cash Flows
TWRR divides the performance period at the point where money enters or leaves the portfolio. Each sub-period return is then linked to calculate the overall performance.
- This helps answer: How did the portfolio manager's investment approach perform, independent of when the investor moved money?
XIRR Reflects the Investor's Cash-Flow Experience
XIRR uses the actual dates and amounts of contributions and withdrawals.
- It answers a different question: What annualised return did this particular investor experience based on their actual cash flows?
SEBI itself notes that an individual investor's performance can differ from the aggregate Investment Approach because of the timing of inflows and outflows and differences in portfolio composition.
PMS Returns vs Benchmark Returns: What Should Investors Compare?
A PMS return becomes more meaningful when compared with an appropriate benchmark.
SEBI requires Investment Approaches to be associated with broadly defined strategies such as Equity, Debt, Hybrid or Multi Asset, and the benchmark selected for an Investment Approach should reflect the core philosophy of that strategy.
For example, investors should not evaluate an equity PMS only by asking whether it produced a positive return. They should also examine how it performed relative to the relevant benchmark over the same period.
Consider:
- PMS return versus benchmark return
- One-, three- and five-year periods where available
- Performance during rising and falling markets
- Degree of portfolio concentration
- Drawdowns and volatility
- Returns after fees and expenses
A 16% return may appear strong in isolation. If the appropriate benchmark returned 20% over the same period, the interpretation changes. Conversely, slightly lower returns may need to be viewed differently if they were achieved with materially lower portfolio risk.
What Costs Should Investors Consider When Calculating PMS Returns?
PMS performance should be evaluated after understanding all applicable costs.
Depending on the agreement, costs may include:
Management Fees
These are fees charged for managing the portfolio and may follow the fee structure agreed with the client.
Performance Fees
Some PMS arrangements charge fees based partly on performance.
Where a performance fee applies, SEBI requires use of the high-water-mark principle, meaning performance-based fees are charged only on gains above the previously achieved high-water mark.
Brokerage and Transaction Costs
SEBI permits brokerage to be charged at actuals as an expense to the client.
Operating Expenses
These may include items such as custody, demat, fund accounting, audit and bank-related charges. Under the current framework, operating expenses excluding brokerage, over and above PMS fees, generally cannot exceed 0.50% per annum of the client's average daily AUM.
Exit Load
Depending on how long the investment has been held and the applicable PMS terms, an exit load may apply to partial or full withdrawals. Current SEBI rules specify maximum exit loads of 3% in the first year, 2% in the second year and 1% in the third year, with no exit load after three years for the standard PMS framework.
Investors should therefore compare PMS strategies using net performance, not returns before costs.
PMS Returns: Gross Returns vs Net Returns
Gross return represents portfolio performance before relevant fees and expenses are deducted. Net return reflects performance after those costs. For investors, net performance is generally more useful because it is closer to the economic outcome of the investment. SEBI requires portfolio managers to report performance data net of all fees and expenses, including taxes, and to include cash and liquid-fund holdings in the calculation.
However, this should not be confused with the investor's final personal income-tax liability. Capital-gains tax and other personal tax consequences depend on the underlying securities, transactions, holding periods and the investor's circumstances.
How Often Should Investors Review PMS Returns?
SEBI's prescribed reporting framework requires portfolio managers to provide quarterly reports to clients, which include portfolio and performance information.
Quarterly review can help investors monitor:
- Portfolio performance
- Benchmark comparison
- Changes in holdings
- Concentration
- Fees and expenses
- Cash flows
- Changes in the investment approach
However, evaluating an equity-oriented PMS based only on a few months of performance can lead to poor conclusions.
Where the strategy is designed for long-term capital growth, investors should examine performance across longer periods and different market conditions rather than reacting to every short-term movement.
Common Mistakes Investors Make When Evaluating PMS Returns
When reviewing PMS returns, investors may focus too heavily on headline performance without considering benchmarks, fees, cash flows, or portfolio risk. Comparing returns on different bases can also lead to misleading conclusions about how a PMS strategy has actually performed.
Comparing XIRR Directly With Another PMS's TWRR
XIRR reflects an individual investor's cash-flow experience, while TWRR is intended to isolate investment performance. Compare like with like.
Looking Only at the Highest Recent Return
One-year performance may reflect a particular market cycle or concentrated investment call. It should not be treated as sufficient evidence of long-term consistency.
Ignoring the Benchmark
A positive return does not necessarily mean the PMS generated strong relative performance.
Comparing Gross and Net Returns
Returns should be compared on the same basis, preferably after applicable fees and expenses.
Ignoring Portfolio Risk
Higher returns accompanied by much larger drawdowns, concentration or volatility may not fit every investor.
Treating Past Returns as Expected Returns
SEBI does not permit portfolio managers to guarantee or assure returns. Historical performance should be treated as evidence of past outcomes, not a promise of future results.
How to Evaluate the Performance of a PMS Strategy
Return should be one part of a broader performance assessment.
| What to Evaluate | What It Tells You |
|---|---|
| TWRR | How the investment approach performed independent of investor cash-flow timing |
| XIRR | What return you personally experienced |
| Benchmark comparison | Whether the strategy added value relative to an appropriate market reference |
| Consistency | Whether performance was dependent on one unusually strong period |
| Drawdown | How much the portfolio declined during difficult periods |
| Concentration | How dependent performance is on a small number of holdings or sectors |
| Portfolio turnover | How frequently securities are bought and sold |
| Net return | What remains after fees and expenses |
| Investment approach | Whether the strategy is behaving as described |
| Time horizon | Whether the evaluation period matches the intended strategy horizon |
Investors should also use the portfolio manager's Disclosure Document, quarterly reports and performance information available through the regulatory reporting framework rather than relying only on marketing presentations.
Final Takeaway: Understanding PMS Returns Before Investing
PMS performance cannot be understood from one return number alone. TWRR helps evaluate the investment approach, while XIRR helps measure the experience of an individual investor whose contributions and withdrawals occur at different times. CAGR and absolute returns can also be useful, but only when they are applied to suitable periods and cash-flow patterns.
Investors should compare returns over consistent periods, use an appropriate benchmark, examine net performance after costs and consider risk alongside return. The objective is not simply to identify the PMS with the highest reported percentage. It is to determine whether the strategy has generated performance that is consistent with its investment approach, benchmark, risk profile and the investor's own financial objectives.
Frequently Asked Questions About PMS Returns
SEBI requires TWRR for reporting Investment Approach performance, while XIRR is also presented to individual investors to reflect their cash-flow experience.
Absolute return measures total gain or loss without considering cash-flow timing, while XIRR annualises returns using the dates and amounts of individual investments and withdrawals.
SEBI requires reported PMS performance data to be net of all fees and expenses, including applicable taxes.
The TWRR of the Investment Approach is presented alongside the trailing return of its selected benchmark for the same period.
There is no fixed return that defines good PMS performance. Investors should assess returns relative to the appropriate benchmark, risk taken, fees and performance across market cycles.
PMS does not have one separate tax rate. Tax treatment depends on the underlying income and transactions. For listed equity meeting the relevant conditions, current rules generally tax short-term gains at 20% and long-term gains at 12.5% above the applicable ₹1.25 lakh threshold.
Yes. Investor cash flows can affect personal returns, which is why XIRR accounts for their timing while TWRR reduces their effect when assessing portfolio performance.
CAGR can be useful for multi-year start-to-end comparisons without irregular cash flows, but TWRR or XIRR is more informative when contributions or withdrawals occur.
Compare net TWRR over the same periods, appropriate benchmarks, drawdowns, portfolio concentration, turnover, fees and the consistency of the investment approach.
Both matter. Returns show the outcome, while risk measures help investors understand the level of volatility, concentration and downside exposure taken to achieve it.
