Start with the target date
Time is one of the most important inputs: a longer horizon can reduce the monthly contribution needed for the same target. Set a date and identify whether the goal is flexible or fixed.
Investment planning guide
Work backwards from a target corpus to a monthly contribution, then test how time and return assumptions change the result.
Estimate SIP returnsA target-based SIP plan is an illustration, not a promise. Use a conservative return assumption, review the plan as the target changes and increase contributions as income grows.
How to use this guide
Time is one of the most important inputs: a longer horizon can reduce the monthly contribution needed for the same target. Set a date and identify whether the goal is flexible or fixed.
A future target often needs to be larger than today’s cost, especially for education, housing and retirement goals. Inflate the current cost before calculating the monthly contribution.
Test more than one return assumption and avoid treating a past return as a guaranteed future result. A conservative scenario helps reveal whether the target is robust.
Equity-oriented investments can fluctuate significantly and may be unsuitable for a near-term goal. As the target date approaches, consider how and when to reduce risk.
A yearly increase in contributions can make the starting SIP more manageable when income is expected to grow. Record the step-up amount and review it with your budget.
Increase the SIP when possible and rebalance the goal if the target, timeline or risk capacity changes. Compare the projected corpus with the amount actually invested, not just the original illustration.
Common questions
No. It illustrates a contribution using an assumed return. Market returns vary, so use a range and build in a margin for error.
Usually yes when the goal is several years away. Estimate what the same goal may cost in the future before calculating the SIP.
Extend the timeline, increase contributions gradually, add a step-up plan, adjust the target or use a combination of existing savings and monthly investing.
