A Systematic Investment Plan, or SIP, is the most popular way Indians invest in mutual funds. Instead of investing a large sum at once, you put in a fixed amount every month — five thousand or ten thousand rupees, for example. The fund house buys units at that month’s price, so you automatically accumulate more units when markets dip and fewer when they rise. This steady rhythm, called rupee cost averaging, removes the pressure of timing the market and turns investing into a habit rather than an event.
The real power of a SIP is compounding. Every instalment you make starts earning returns, and those returns begin earning returns of their own. Growth looks modest in the early years, but as the balance builds, the yearly growth starts to exceed what you put in. That is why financial planners repeat the same advice: start early, stay invested, and let time do the heavy lifting. Even a small monthly amount can grow into a meaningful corpus if it gets enough years to compound.
This SIP calculator helps you see that future before you commit a single rupee. Enter your monthly investment, expected annual return, and tenure, and the tool projects a maturity value split between the money you put in and the growth compounding added. It suits first-time investors comparing funds, salaried savers setting retirement targets, and parents planning a child’s education. Treat every figure as an estimate for planning, not a promise — market-linked returns move up and down from year to year.
How it works
The calculator treats your SIP as a series of separate monthly investments. Over ten years, the first instalment stays invested for the full ten years, the second for one month less, and the final one for only a single month. Each instalment grows at the expected annual return for the time it remains invested, compounding monthly. The tool adds up the grown value of every instalment to reach the projected maturity amount.
Because the money goes in month by month, the annual return you enter is converted into an equivalent monthly growth rate inside the calculation. This monthly compounding is why a small change in the assumed return makes such a large difference over long tenures — the rate keeps working on an ever-growing balance. The calculator also totals everything you would have invested, so you can see at a glance how much of the final figure came from your own contributions and how much came from compounding. Running the numbers with a slightly lower return shows you a cautious scenario worth planning around.
How to use this tool
- Enter your monthly SIP amount in rupees, for example five thousand.
- Enter the expected annual return you are planning around, such as twelve percent.
- Choose the investment tenure in years.
- Press Calculate to see the projected maturity value.
- Compare the total invested with the estimated growth in the breakup.
- Re-run with a lower return to see a cautious, realistic scenario.
Practical tips
- Start with an amount you can sustain for the full tenure — a SIP you abandon helps less than a smaller one you keep. You can always increase it later.
- Match your expected return to the fund type: equity funds may aim higher long-term, while debt funds grow more slowly.
- Expense ratios, exit loads, and capital gains tax all trim the final amount — the calculator shows a before-tax, before-charge figure, so keep that gap in mind.
- Review yearly instead of watching daily prices — reacting to every dip usually does more harm than the dips themselves.
Frequently asked questions
Are the returns shown by the calculator fixed?
No. The calculator assumes the expected return you enter holds steady for the whole tenure, but real mutual fund returns rise and fall with the market. Some years will beat your assumed rate and some will lag it. Use the projection to compare plans and set a savings target, not as a prediction of what you will receive.
What expected return rate should I enter?
Indian equity mutual funds have often delivered around ten to fourteen percent per year over long periods, but past performance never guarantees future results. For cautious planning, most investors enter ten to twelve percent. Run the calculation twice — once optimistic, once conservative — to see a realistic range of outcomes instead of a single hopeful number.
Does the calculator include taxes and fund charges?
No. The projection is shown before the fund's expense ratio, any exit load, and capital gains tax are applied. In India, long-term capital gains on equity funds above one point two five lakh rupees a year are taxed. The amount you finally receive will be lower than the projected figure, so keep that gap in mind.
What if I want to increase my SIP every year?
A fixed SIP is only one approach. If your income rises yearly, a step-up SIP — raising your contribution by a fixed percentage each year — can build a much larger corpus, because every increase also compounds. Try our Step-Up SIP Calculator to model that style of investing instead of this fixed-amount version.
Is it risky to start a SIP when markets are falling?
Starting in a downturn usually helps SIP investors: when prices are low, your fixed amount buys more units, and those extra units grow strongly in the recovery. SIPs are built for this uncertainty — waiting for the perfect moment usually costs more in missed time than it saves in avoided dips.
Can I change or stop my SIP later?
Yes. SIPs are flexible — you can increase, decrease, pause, or stop your monthly investment through your fund house or investment app at any time, usually with no penalty. This calculator models what happens if you stay consistent, but life changes — build a plan you can adjust rather than one demanding perfection.
Note: These projections are estimates for planning only — mutual fund returns vary with market conditions and are not guaranteed. This tool is not financial advice.
