A SIP calculator shows exactly how much wealth your monthly mutual fund investments will build over time — factoring in compounding returns automatically. A Systematic Investment Plan (SIP) is the most popular way for Indian investors to build wealth through mutual funds. Instead of investing a lump sum, SIP lets you invest a fixed amount every month — as little as ₹100 — and benefit from rupee cost averaging and the power of compounding.
This guide explains the SIP formula, shows you exactly what ₹500, ₹1,000, ₹5,000 invested monthly will grow to over 10, 20, and 30 years, compares SIP against FD and RD, and walks you through the best platforms to start investing in India today.

How SIP Works — Rupee Cost Averaging Explained
SIP works on two powerful principles: rupee cost averaging and compounding.
Rupee Cost Averaging
When you invest a fixed amount every month, you automatically buy more mutual fund units when prices are low and fewer units when prices are high. Over time, this averages out your purchase cost, reducing the risk of investing at a market peak.
Example: You invest ₹1,000/month in a fund:
- Month 1: NAV ₹50 → you buy 20 units
- Month 2: NAV ₹40 → you buy 25 units (market dip — you benefit!)
- Month 3: NAV ₹55 → you buy 18.18 units
- Average cost: ₹44.56/unit (vs ₹48.33 if you had bought at average NAV)
The Power of Compounding
Compounding means your returns earn returns. In SIP, dividends and capital gains are reinvested, generating their own returns the following month. The longer you invest, the more dramatic this effect becomes — which is why starting early is the single most important factor in SIP success.
The SIP formula
Future Value = P × [((1 + r)^n − 1) / r] × (1 + r)
- P = Monthly investment amount
- r = Monthly rate of return (annual rate ÷ 12)
- n = Total number of months
Example: ₹5,000/month for 20 years at 12% annual return: FV = 5000 × [((1.01)^240 − 1)/0.01] × 1.01 = ₹49.96 lakh
SIP Returns Table — How Much Will You Earn?
Based on 12% annual returns (approximate long-term NIFTY 50 CAGR), here is what your monthly SIP could grow to:
| Monthly SIP | 10 Years | 15 Years | 20 Years | 30 Years |
|---|---|---|---|---|
| ₹500 | ₹1.16 L | ₹2.52 L | ₹4.99 L | ₹17.65 L |
| ₹1,000 | ₹2.32 L | ₹5.05 L | ₹9.99 L | ₹35.30 L |
| ₹2,000 | ₹4.64 L | ₹10.10 L | ₹19.98 L | ₹70.59 L |
| ₹5,000 | ₹11.62 L | ₹25.23 L | ₹49.96 L | ₹1.76 Cr |
| ₹10,000 | ₹23.23 L | ₹50.46 L | ₹99.91 L | ₹3.53 Cr |
| ₹25,000 | ₹58.08 L | ₹1.26 Cr | ₹2.50 Cr | ₹8.83 Cr |
Note: 12% is a historical approximation — actual returns vary. Past performance does not guarantee future results. Consult a SEBI-registered advisor.
Step-Up SIP
A step-up SIP automatically increases your monthly investment by a fixed percentage each year (typically 10%). If you start with ₹5,000/month and increase by 10% annually, your 20-year corpus grows from ₹49.96L to approximately ₹1.2 Cr — more than double — due to the compounding effect of higher investments in later years.
SIP vs FD vs RD — Which Gives Better Returns?
Many Indian investors default to Fixed Deposits (FD) and Recurring Deposits (RD) because they are familiar and safe. Here is an honest comparison:
| Parameter | SIP (Mutual Fund) | Bank FD | Bank RD |
|---|---|---|---|
| Expected Returns | 10–15% (market-linked) | 6.5–7.5% | 6–7% |
| Risk | Market risk (low to high) | Very low | Very low |
| Liquidity | High (exit anytime except ELSS) | Lock-in with penalty | Lock-in with penalty |
| Tax on gains | LTCG 12.5% (above ₹1.25L) | As per income slab | As per income slab |
| Inflation beating | Yes (historically) | Rarely | Rarely |
| Minimum investment | ₹100/month | ₹1,000 typically | ₹100/month |
Tax-Saving SIP: ELSS Funds
Equity Linked Savings Schemes (ELSS) are mutual funds that qualify for Section 80C deduction — up to ₹1.5 lakh per year. They have a 3-year lock-in (shortest among 80C instruments) and have historically delivered 12–15% CAGR. For investors in the 20–30% tax bracket, ELSS is often the best 80C option.

Important SEBI regulations
All mutual funds in India are regulated by SEBI (Securities and Exchange Board of India). SEBI mandates: (1) Daily NAV publication, (2) Standardised expense ratios capped by category, (3) Mandatory KYC for all investors, (4) Direct vs Regular plan distinction (always choose Direct for lower expense ratio).

Frequently Asked Questions
What is the minimum SIP amount in India?+−
Most mutual funds accept SIP from ₹100/month (HDFC, Axis, many others). Some require ₹500 or ₹1,000 minimum. There is no maximum limit. You can start with ₹100 and increase as your income grows.
Is SIP safe? Can I lose money?+−
SIP in equity mutual funds is market-linked and carries market risk — your investment can go down in value during market downturns. However, SIP's rupee cost averaging reduces timing risk. Over 10+ year periods, diversified equity SIPs have historically delivered positive returns. Debt SIPs carry lower risk.
Can I stop SIP anytime?+−
Yes, SIP can be paused or cancelled anytime without penalty (except ELSS funds which have a 3-year lock-in). Your existing invested units remain in the fund and continue to grow. Simply log in to your platform and pause/cancel the SIP mandate.
How is SIP taxed in India?+−
For equity SIPs: Short-Term Capital Gains (STCG) tax of 20% on units sold within 1 year. Long-Term Capital Gains (LTCG) tax of 12.5% on gains above ₹1.25 lakh per year for units held more than 1 year. For ELSS: locked for 3 years, then LTCG applies. Debt SIPs: gains taxed as per your income tax slab.
What is the difference between SIP and lump sum investment?+−
SIP invests a fixed amount monthly regardless of market conditions, reducing timing risk through rupee cost averaging. Lump sum invests everything at once — better if you are confident the market is at a low point, but worse if you invest at a peak. For most retail investors without market expertise, SIP is recommended over lump sum.
