Understand the calculation

What is a Goal Planning SIP Calculator?

A normal SIP calculator answers “what could this monthly investment become?” This goal-planning calculator reverses the question: “given the amount I need, how much should I start investing each month?” It separately projects any existing corpus and can increase the target for inflation.

Use the return and inflation fields as planning assumptions, not promises. The annual step-up option solves for the starting SIP when you expect to increase contributions each year.

How the required SIP is solved

Target gap = inflation-adjusted target − future value of existing corpus; starting SIP is solved so projected future value equals that gap.

For a flat SIP FinPockett uses the annuity-due future-value formula. When step-up is enabled, the tool simulates monthly deposits and solves the starting SIP numerically.

Use three return assumptions, not one

A target plan is more robust when you test a conservative, base and higher-return case. If a small reduction in assumed return makes the required SIP unaffordable, the plan is relying too heavily on market performance rather than contributions.

Existing investments reduce the gap — but only if they belong to the same goal

Only include assets you genuinely intend to use for this target. Emergency savings, short-term cash or investments earmarked for another goal should not be counted simply to make the funding percentage look better.

Frequently asked questions

Is this the same as the normal SIP Calculator?

No. The normal SIP Calculator starts with a known monthly contribution and projects a corpus. This calculator starts with a known target and solves the required starting SIP.

Does step-up make the starting SIP lower?

Yes, if future contributions actually rise as assumed. The trade-off is that later-year cash commitments become larger.

Should I use inflation?

Use it when your target is expressed in today’s rupees. If your target already represents the future amount you need, leave inflation at zero.

Are returns guaranteed?

No. The calculation only shows what the selected return assumption would imply.
