About this calculator

Time Duration – SIP — explained

The Time Duration SIP Calculator tells you exactly how many months your monthly SIP will take to reach a chosen target corpus. This is the ideal Indian SIP planner when your monthly investment amount is fixed — often by salary capacity — and you want to know how long until you hit your wealth goal. Common use cases include figuring out when you'll save up for a car, when your education corpus will be ready, when your wealth target will be achieved at the current SIP rate, or when you can afford early retirement at your current savings pace.

Unlike a Goal SIP Calculator (which solves for monthly amount), this tool fixes the SIP amount and solves for time. Enter the monthly SIP, target corpus, and expected return — the calculator iterates month by month until the corpus crosses the target, returning the precise duration in years and months.

What is the Time Duration – SIP?

Time-to-target SIP is a financial planning concept that fixes your monthly SIP amount and solves for the duration needed to reach a goal. This is particularly useful when your monthly investing capacity is constrained (e.g., maximum ₹15,000/month after EMI and rent) and you want a realistic timeline rather than a 'required' amount you can't afford.

How it works — the formula

The calculator iterates month by month, accumulating each SIP instalment with monthly compounding at the assumed rate, and stops the moment the corpus crosses the target. The result is expressed in years and remaining months. The underlying maths is the standard SIP future-value formula solved iteratively for n.

How to use this calculator

  1. 1Enter your monthly SIP amount in rupees
  2. 2Enter the target corpus you want to accumulate
  3. 3Choose your expected annual return rate
  4. 4Read the duration in years and months plus your total contribution
  5. 5If the duration is too long, increase the SIP, switch to step-up, or pick a higher-return fund category
  6. 6Compare different return assumptions to see how fund choice impacts timeline

Frequently asked questions

Why does a small change in return rate move the timeline so much?
Compounding is exponential — a 2% lower return over a long horizon can push the timeline by years. That's why low-cost index funds (with smaller expense ratios eating into returns) often beat actively managed funds on net returns over decades.
Can I shorten the duration by increasing the SIP later?
Yes. Step-up SIPs (annual increment of 10–15%) reach the same target meaningfully faster. Try our dedicated Step-Up SIP Calculator to see the comparison.
What if I stop the SIP for a few months?
Pausing the SIP doesn't reset progress, but the corpus stops growing from contributions during the pause. Restart as soon as possible — every missed instalment delays the timeline.
Does this account for partial withdrawals mid-SIP?
No. The calculator assumes you stay invested until the corpus crosses the target. Partial withdrawals would extend the timeline.
Can I use this for retirement timeline planning?
It tells you when a target corpus will be hit at the current SIP, but for full retirement planning use our Retirement Calculator which factors in inflation and post-retirement expenses.
Is the timeline before or after tax?
Pre-tax. For an after-tax timeline, reduce your assumed return slightly (e.g., assume 11% net instead of 12% gross).
