Systematic Investment Plans are the most accessible way for Indian investors to participate in equity markets — but compounding is notoriously difficult to intuit. Most people significantly underestimate what consistent monthly investments do over a decade or two. Investing ₹5,000 per month for 20 years at a 12% annual return does not simply give you 240 × ₹5,000 = ₹12 lakh — it gives you over ₹49 lakh, of which ₹37 lakh is pure investment growth. The Utility Spark SIP Calculator helps you see this clearly: enter your monthly investment amount, expected annual return rate, and investment duration, and the calculator shows you the maturity corpus, total amount invested, and total wealth created through compounding. It also generates a year-by-year growth chart so you can visualise the acceleration that compound interest produces in the later years of a long investment horizon. Use it to plan investment amounts for specific financial goals — a child's education corpus, a down payment fund, or retirement savings — and work backwards from your target.
lightbulb When to use this tool
- check_circle Calculating how much a specific monthly SIP amount will grow to over 10, 15, or 20 years for a retirement or education planning goal.
- check_circle Determining what monthly SIP amount you need to reach a target corpus (e.g., ₹1 crore in 15 years).
- check_circle Comparing the impact of starting a SIP now versus starting five years later — the 'cost of delay' in compounding terms.
- check_circle Evaluating whether to invest a lump sum or a SIP by comparing their projected maturity values.
- check_circle Setting realistic expectations about mutual fund SIP returns across different time horizons.
Why use our tool?
Year-by-Year Growth Visualisation
A simple final maturity number obscures the compounding curve. The calculator provides a year-by-year breakdown showing the corpus at the end of each year, making the exponential acceleration of compound growth visible. The last few years of a long SIP contribute disproportionately to the final corpus — and seeing this displayed clearly motivates continued investment.
Wealth Created vs Amount Invested — Side by Side
The calculator separates your total invested amount from the wealth created through returns. For a ₹5,000/month SIP over 20 years at 12%: total invested = ₹12 lakh, wealth created = ₹37 lakh, total maturity value = ₹49 lakh. Seeing these numbers separately makes the power of compounding concrete rather than abstract.
Goal-Based Reverse Calculation
Enter your target corpus and investment duration, and the calculator works backwards to tell you what monthly SIP amount will reach that goal at a given return rate. Planning for ₹1 crore in 18 years at 12% expected return? The calculator tells you the required monthly SIP is approximately ₹14,400.
Multiple Return Scenarios
Equity mutual fund returns are variable — a 12% long-term average could perform anywhere between 8% and 15% in any specific period. The calculator lets you run scenarios at conservative (8%), moderate (12%), and optimistic (15%) return assumptions to understand the range of outcomes rather than anchoring to a single projection.
Completely Private — No Investment Data Shared
Your planned investment amounts and financial goals are personal. This calculator runs in your browser — no SIP amount, expected return, or target corpus figure is transmitted to any server or shared with any financial institution.
How it works
Enter your monthly SIP investment amount in rupees.
Enter your expected annual return rate (%). For Indian equity mutual funds, historical long-term CAGR ranges from 10%–15% — use 12% as a moderate assumption for planning.
Enter the investment duration in years.
The calculator displays: Total amount invested, Estimated returns (wealth created), Total maturity value.
View the year-by-year breakdown to see the growth curve — notice how the corpus accelerates significantly in later years.
Use the reverse calculator mode to input a target corpus and duration to find the required monthly SIP amount.
Examples
science Retirement Corpus Planning at 45
Monthly SIP: ₹15,000 | Duration: 20 years | Return: 12% p.a.
Total invested: ₹36,00,000 (₹36 lakh)
Estimated returns: ₹1,11,35,000 (₹1.11 crore)
Maturity corpus: ₹1,47,35,000 (₹1.47 crore)
Wealth created: 3.09× the invested amount through compounding
science Cost of Delay — Starting Now vs 5 Years Later
Scenario A: ₹10,000/mo for 20 years at 12% → Maturity: ₹98.23 lakh
Scenario B: ₹10,000/mo for 15 years at 12% (starting 5 years later) → Maturity: ₹50.46 lakh
Cost of 5-year delay: ₹47.77 lakh in forgone compounding returns — on the same monthly investment amount
