Why your SIP return may differ from a published number
A SIP outcome depends on when each contribution was invested, what happened in the market afterwards and how returns are measured.
The starting date and market path matter
A scheme’s published return usually summarises a specific period and investment pattern. An SIP makes multiple purchases over time, each at a different NAV. Two investors in the same scheme can therefore have different outcomes if they started, paused, increased or redeemed their investments at different times.
Advertisements may highlight a historical period that is favourable to the product. That number can be mathematically correct for its stated window and still be a poor guide to a different investor’s experience. Look for the period, benchmark, plan, option, calculation method and required risk disclaimer; avoid treating any past return as an expected return.
How to review your own SIP
- Download a transaction statement with each instalment date, amount and units.
- Use a money-weighted return measure such as XIRR for dated cash flows, with the current portfolio value and valuation date recorded.
- Check that switches, withdrawals and IDCW distributions are treated consistently.
- Compare against an appropriate benchmark over the same interval and using a compatible calculation method.
- Review goal progress and risk fit, not only the latest return ranking.

Plan with scenarios, not promises
For a financial goal, test a range of outcomes, contribution levels, time horizons and inflation assumptions. A step-up contribution can be one scenario if your income and budget support it; it is not a guaranteed way to “beat inflation.” Keep emergency savings and near-term needs separate from market-linked investments, and consider the scheme’s risk and time horizon.
Markets can fall, and periodic investing does not guarantee profit or prevent loss. Do not stop or continue an investment solely because of this article; revisit your objective, ability to take risk and the scheme information before making changes.
Frequently asked questions
Why can my SIP return differ from a fund's advertised return?
Published figures and your SIP may use different start dates, cash-flow patterns, plans, options, return methods and valuation dates. Your instalments buy units at different NAVs, so timing changes your personal outcome.
Is there a realistic SIP return I can assume?
No single return assumption is suitable for every fund, asset class, period or investor. Use scenarios to test whether a goal is resilient; do not treat an advertised or historical return as a forecast or guarantee.
Does a SIP protect me from market losses?
No. A SIP is a way to invest periodically and does not remove market, credit, liquidity or scheme-specific risks. The value of units can fall, and returns are not assured.

SIP profit divided by contributions is not an annual rate
Twelve monthly contributions of ₹5,000 total ₹60,000. If their ending value is ₹63,000, the simple gain on contributions is 5%. It is not a 5% annualized return: the later contributions were invested for much less than a year.
How to use this in your decision
List every contribution date as a negative cash flow and the final value at its date as a positive flow, then compute XIRR. Include withdrawals or distributions. An advertisement's assumed return is an input to a projection, not a promise that your dated cash flows will earn it.
Example assumptions: A cash-flow example only. XIRR depends on the exact dates and can be unstable for unusual cash-flow patterns.
