SIP Calculator

A Systematic Investment Plan is a disciplined way of investing in mutual funds. Instead of investing a large lump sum at once, you invest a fixed amount — say 5,000 or 10,000 — every month, automatically. This approach has two powerful advantages. First, rupee cost averaging: because you invest the same amount regardless of market conditions, you automatically buy more units when prices are low and fewer when prices are high, smoothing out volatility. Second, compounding: your returns themselves earn returns, and over long periods this effect becomes the dominant driver of wealth creation.

The numbers are striking. Investing 10,000 per month at an assumed 12% annual return grows to roughly 50 lakh in 15 years — of which only 18 lakh is money you actually invested. The remaining 32 lakh is the compounding effect. Extend the same SIP to 25 years and the corpus crosses 1.8 crore. Time in the market, not timing the market, is what builds wealth.

The calculator uses the standard future value of an annuity due formula:

FV = M × ((1 + i)^n − 1) / i × (1 + i)

Where M is your monthly investment, i is the monthly rate of return (annual rate divided by 12), and n is the total number of monthly instalments. The final multiplication by (1 + i) reflects that SIP instalments are typically invested at the beginning of each period. Note that mutual fund returns are market-linked and not guaranteed — the expected return you enter is an assumption, not a promise. Historical long-term returns of diversified equity funds have been in the 10-14% range, but past performance does not guarantee future results.

A Systematic Investment Plan (SIP) represents a structured approach to asset allocation within modern capital markets. By committing a rigid, pre-defined liquidity amount at recurring chronological intervals (monthly cycles), an investor systematically mitigates the operational hazards associated with market-timing dependencies. This programmatic asset accumulation relies heavily on the principle of dollar-cost averaging (or rupee-cost averaging). During phases of bearish market correction, the fixed recurring capital purchases a significantly higher volume of equity units or mutual fund shares. Conversely, during structural bullish expansions, the automated capital stream acquires a smaller pool of high-priced asset blocks. Over long-term tracking horizons — typically spanning 60, 120, or 240 continuous financial cycles — this mechanism naturally drives down the global weighted average cost basis of the entire investment portfolio, maximizing geometric mean returns.

The core algorithmic calculation engine utilizes the standardized future value formula: Future Value = M × [((1 + i)^n − 1) / i] × (1 + i). Within this compounding paradigm, the variable 'M' denotes the static monthly liquid contribution. The factor 'i' represents the projected annualized CAGR return index normalized by dividing by 12 base units and scaling by 100. The power factor 'n' marks the absolute total number of cumulative months across the planned horizon.

Start early. A SIP started at 25 can produce more than double the corpus at 60 of the same SIP started at 35, purely due to compounding. Increase your SIP annually. A step-up of just 10% per year, in line with salary growth, dramatically increases the final corpus. Stay invested through downturns. Stopping a SIP during a market fall defeats the purpose of rupee cost averaging — downturns are precisely when your instalments buy the most units. Match the horizon to the goal. Equity SIPs suit goals five or more years away; for shorter goals, debt funds or deposits are usually more appropriate.
