A Systematic Investment Plan (SIP) is one of the most powerful wealth-building tools available to Indian investors. By investing a fixed amount every month in mutual funds, you benefit from rupee cost averaging and the power of compounding — and you don't need a large lump sum to start. This guide explains exactly how SIP works and how to use our calculator to plan your financial goals.
How SIP Works: The Compounding Formula
SIP uses compound interest to grow your wealth. The formula for SIP maturity value is:
M = Maturity Value | P = Monthly Investment | r = Monthly Rate | n = Months
Example: Investing ₹5,000/month for 20 years at a 12% annual return:
| Parameter | Value |
|---|---|
| Monthly Investment | ₹5,000 |
| Annual Return (estimated) | 12% |
| Investment Period | 20 years (240 months) |
| Total Amount Invested | ₹12,00,000 |
| Estimated Maturity Value | ₹49,96,000 (~₹50 lakhs) |
| Total Wealth Gained | ₹37,96,000 |
Your ₹12 lakh investment grows to nearly ₹50 lakhs — the remaining ₹38 lakhs is pure compounding at work.
Rupee Cost Averaging: Your Protection Against Volatility
When markets fall, your fixed SIP amount buys more units. When markets rise, you buy fewer units. Over time, this averages out your purchase cost and reduces the risk of investing a lump sum at the wrong time.

Frequently Asked Questions
Is SIP return guaranteed?
No. SIP returns depend on mutual fund performance, which is market-linked. Equity funds historically deliver 10–15% CAGR over 10+ year periods, but past performance does not guarantee future returns. Debt fund SIPs offer lower but more stable returns of 6–8%.
Can I pause or stop a SIP?
Yes. You can pause a SIP for 1–3 months (most fund houses allow this) or stop it entirely through the fund's app or your broker without any penalty. Your existing investments continue to remain invested.
What is the minimum SIP amount?
Most mutual funds accept a minimum of ₹100–₹500 per month. Some ELSS (tax-saving) funds start at ₹500. You can start small and increase as your income grows using a Step-Up SIP.
