Chart shows year-wise invested amount vs. corpus value.
A SIP calculator is an online financial tool that estimates the future value of a Systematic Investment Plan (SIP) in mutual funds. You enter three simple details – your monthly investment amount, the expected rate of return and the investment duration – and the calculator instantly tells you how much your money will grow to at the end of the period. Our advanced version goes further and also supports step-up SIPs (where you increase the contribution every year), inflation-adjusted returns, and a one-time lumpsum on top of the monthly SIP, giving you a complete picture of your wealth-building journey.
The beauty of a SIP lies in two powerful forces working together: rupee-cost averaging and compounding. Rupee-cost averaging means you buy more units when prices are low and fewer units when prices are high, which brings down your average purchase cost over time. Compounding means the returns you earn start generating their own returns, accelerating your wealth exponentially in the later years of the investment. A SIP calculator makes these invisible forces visible by projecting them into an easy-to-understand number and a year-wise growth chart.
At its core, a SIP is a series of monthly contributions that each grow at the assumed rate of return until the end of the investment period. Mathematically, this is an annuity – a stream of equal payments – and the future value of that annuity is what the calculator returns. The standard formula used by virtually every SIP calculator in India is:
FV = P × [ ((1 + r)^n – 1) / r ] × (1 + r)
In plain English, that formula says: take your monthly investment (P), multiply it by the compounding factor over n months at monthly rate r, and then multiply once more by (1 + r) because each SIP instalment at the start of the month compounds for an extra period. Here is what each variable means:
Our calculator uses monthly compounding because that is how mutual fund NAVs actually behave – the value is marked to market every business day and effectively compounds at every SIP instalment. When you turn on the step-up option, the formula is applied year by year: the monthly amount grows by the chosen percentage every twelve months, and the balance carried forward from the previous year keeps compounding. When you turn on inflation, the nominal maturity value is discounted by (1 + inflation)^years to show the real purchasing power of your corpus at the end.
Let's walk through a concrete example to make the formula tangible. Assume you invest ₹10,000 per month for 10 years, expecting an annual return of 12%. Plugging the numbers in:
Future Value = 10,000 × [((1.01)^120 – 1) / 0.01] × 1.01 ≈ ₹23.23 lakh. Out of that, you invested ₹12 lakh (₹10,000 × 120) and earned ₹11.23 lakh in returns. Your money almost doubled, and the returns component is nearly as large as your total invested amount. This is the compounding effect – something that a fixed deposit or a simple-interest product can never achieve.
Different SIP amounts and durations produce very different outcomes. Here is a quick reference table assuming a 12% annual return, to help you visualise what a regular SIP can achieve:
| Monthly SIP | 5 Years | 10 Years | 15 Years | 20 Years | 25 Years |
|---|---|---|---|---|---|
| ₹1,000 | ₹0.83 L | ₹2.32 L | ₹5.05 L | ₹10.00 L | ₹18.98 L |
| ₹2,500 | ₹2.06 L | ₹5.81 L | ₹12.62 L | ₹24.99 L | ₹47.45 L |
| ₹5,000 | ₹4.12 L | ₹11.62 L | ₹25.23 L | ₹49.96 L | ₹94.88 L |
| ₹10,000 | ₹8.25 L | ₹23.23 L | ₹50.46 L | ₹99.91 L | ₹1.89 Cr |
| ₹25,000 | ₹20.62 L | ₹58.08 L | ₹1.26 Cr | ₹2.49 Cr | ₹4.74 Cr |
Notice how a ₹5,000 monthly SIP for 25 years crosses the ₹90 lakh mark, while doubling the amount to ₹10,000 roughly doubles the corpus to ₹1.89 Cr. Doubling the time, however, does much more than doubling the output, because compounding becomes dramatically more powerful in the last ten years of a long SIP. The lesson is clear – start early, even if the amount is small, and let time do the heavy lifting.
Many new investors wonder what they can build on a tight budget. A simple ₹1,000 per month SIP over 20 years at 12% grows to approximately ₹10 lakh. You will have invested ₹2.4 lakh over that period, and the remaining ₹7.6 lakh is pure compounding. This is often the difference between finishing life with a token savings balance and having enough for a child's higher education.
A middle-class earner investing ₹5,000 every month for 15 years at 12% will build a corpus of roughly ₹25 lakh against an invested amount of ₹9 lakh. The multiplier here is almost 2.8x on the money invested, because the last five years of the SIP are compounding aggressively on the base built in the first ten years.
A young professional starts with ₹5,000 per month and raises the amount by 10% every year, matching typical salary hikes. Over 20 years at 12%, the corpus balloons to about ₹83 lakh – more than 1.6x the flat-₹5,000 SIP. Step-up SIPs are arguably the single biggest secret weapon of retail investors in India and every calculator on this site supports them.
SIPs have become the default wealth-building tool for Indian investors for several reasons. Unlike lumpsum investments which require perfect timing and a large upfront corpus, SIPs let you start with as little as ₹500 per month, spread your risk across market cycles, and automate the entire process so that discipline replaces willpower. Below are the most important benefits:
SIPs are ideal for anyone with a regular income and a time horizon of at least five years. Young earners should prioritise equity SIPs to maximise the compounding runway. Mid-career professionals can use a blend of equity and hybrid funds. Near-retirees typically switch the mix towards debt funds while still running smaller equity SIPs to beat inflation. Business owners with lumpy incomes often combine quarterly lumpsums with small monthly SIPs to capture both opportunistic and disciplined investing.
The honest answer is "it depends". Mathematically, if markets went up in a perfect straight line, a lumpsum invested on day one would always win because 100% of the money is working from the very beginning. In reality, markets are volatile, and most investors do not have a large lumpsum lying around – they have a salary that arrives every month. For that reason, SIPs usually deliver comparable returns to lumpsums at a fraction of the behavioural risk. A common optimal strategy is to use an STP – park a lumpsum in a liquid fund and transfer a fixed amount into equity every month – which is exactly what many professional advisors recommend.
Even with a tool as simple as a SIP, investors routinely shoot themselves in the foot. The three most common mistakes are stopping a SIP during a market crash (the exact moment you want to be buying), not stepping up the amount with salary growth, and picking funds based on last year's star ratings instead of long-term consistency. A disciplined SIP in a boring, low-cost index fund will beat a frantically managed portfolio of hot picks in almost every 10-year window.
Using the calculator above is straightforward. Enter your monthly investment in the first field – you can either type a number or drag the slider. Set an expected annual return; 12% is a reasonable default for diversified equity funds, while 8–9% is conservative for hybrid funds. Choose your duration, typically between 10 and 25 years for wealth creation goals. Switch on step-up SIP if you plan to increase contributions annually, and enable the inflation toggle to see the real purchasing power of your corpus. If you also have a lumpsum you'd like to blend in, toggle that on as well. The calculator updates instantly – there is no submit button – and the year-wise chart helps you visualise the compounding curve.

Historically, diversified equity mutual funds in India have returned 11–14% annualised over 15+ year windows. A conservative planning figure is 12% for equity funds and 7–8% for debt funds. For hybrid funds, 9–10% is reasonable.
No – the output is pre-tax. Equity mutual funds held over a year attract 10% long-term capital gains tax above ₹1 lakh per year under the old rules (subject to changes in current finance acts). Use our income tax calculator for post-tax planning.
Most mutual fund houses allow SIPs from as low as ₹100 or ₹500 per month. There is no upper limit.
Yes. Play with different combinations until the maturity value matches your goal (for example, ₹50 lakh for a child's education in 15 years). You can also work backwards from a target using our retirement calculator.
Nothing drastic. Your SIP continues from the next month. Some fund houses may charge a small auto-debit bounce fee if the instalment was set up via NACH and the bank balance was insufficient. Missing occasional instalments does slightly reduce the final corpus but does not cancel the SIP.
Over long horizons, equity SIPs have historically outperformed FDs by a wide margin because FD returns barely beat inflation after tax. However FDs are safer and have guaranteed returns. See our SIP vs FD guide for a detailed comparison.
No, the calculator assumes a clean rate of return. In practice, exit loads (usually 1% if redeemed within a year) and expense ratios (0.5–2% per year) slightly reduce actual returns. Using a realistic return like 11% instead of 13% is a simple way to account for them.
