SIP Calculator — Calculate Mutual Fund SIP Returns

See how your monthly investments grow with the power of compounding.

What is SIP?

A Systematic Investment Plan (SIP) allows you to invest a fixed amount of money every month into mutual funds. It is one of the most powerful wealth-building tools available to Indians. Through the mechanism of rupee cost averaging, SIP protects you from market volatility — when markets fall, your fixed investment buys more units, and when markets rise, your existing units appreciate in value. You can start a SIP with as little as ₹500 per month through platforms like Groww, Zerodha, or directly through SBI, HDFC, and ICICI mutual fund AMCs. The true magic lies in compounding: your returns earn returns, creating exponential growth over decades.

How to Use This SIP Calculator

  1. Enter Monthly Investment: Set the amount you want to invest every month using the slider.
  2. Set Expected Return Rate: Choose the annual return rate. 12% is the historical average for equity funds in India.
  3. Choose Duration: Select how many years you plan to stay invested.
  4. View Your Corpus: See your total value, invested amount, and estimated returns instantly.
  5. Try Step-up SIP: Switch to the Step-up tab to see how increasing your investment yearly supercharges your returns.

SIP Formula Explained

The future value of a SIP is calculated using the compound interest formula:

FV = P × ((1 + r)n - 1) / r × (1 + r)

Example: ₹5,000/month for 10 years at 12% annual return → Monthly rate r = 0.01, Months n = 120. Future Value = ₹11,61,695. You invest ₹6,00,000 total and earn ₹5,61,695 in returns — nearly doubling your money.

SIP vs Lump Sum — Which is Better?

This is one of the most debated topics in personal finance. The answer depends on your situation:

  • SIP is better for salaried individuals — invest from monthly income without needing a large sum upfront.
  • Lump sum can be better during market crashes — buying at low prices maximizes future gains.
  • SIP reduces risk through rupee cost averaging — you don't need to time the market.
  • Best approach: Use both together — SIP for regular income, lump sum for windfalls like bonuses.

The Power of Compounding in SIP

Compounding is what makes SIP truly powerful. Your returns earn returns, creating exponential growth:

  • ₹5,000/month at 12% → ₹11.6L in 10 years
  • ₹5,000/month at 12% → ₹49.9L in 20 years
  • ₹5,000/month at 12% → ₹1.89Cr in 30 years

Notice how the growth accelerates: 10 more years (from 20 to 30) adds over ₹1.4 Crore. Starting early matters more than the amount.

Best SIP Amount for Your Goal

Use the Goal Calculator above to find exactly how much monthly SIP you need. Here are common goals: to build ₹1 Crore in 20 years at 12% returns, you need approximately ₹10,100/month. To reach ₹50 Lakh in 15 years, you need about ₹10,000/month. The key insight is that starting early with even a small amount is far more effective than starting late with a larger investment.

Frequently Asked Questions

You can start a SIP with as little as ₹500 per month. However, financial advisors generally recommend investing at least 20% of your monthly income. For someone earning ₹30,000/month, a SIP of ₹5,000–₹6,000/month is a good starting point. The most important thing is to start early, even with a small amount, and increase it gradually.
Large-cap equity mutual funds in India have historically delivered 10–12% annual returns over long periods (10+ years). Mid-cap and small-cap funds have delivered 12–15% but with higher volatility. Debt funds deliver 6–8%. Our calculator defaults to 12%, which is a reasonable long-term estimate for diversified equity funds.
SIP itself is a method of investing, not an investment product. The safety depends on the mutual fund you choose. Equity mutual funds carry market risk — their value can go down in the short term. However, over a 10+ year horizon, diversified equity funds have historically never given negative returns. Debt fund SIPs are safer but give lower returns.
Yes. Most mutual funds allow you to pause or stop your SIP anytime without any penalty. The units you have already purchased remain invested and continue to grow. You can restart your SIP later. There is no lock-in period for most open-ended mutual fund SIPs (except ELSS funds which have 3-year lock-in).
Step-up SIP (also called top-up SIP) is a feature where your monthly investment automatically increases by a fixed percentage every year. For example, if you start with ₹5,000/month and set a 10% annual step-up, it becomes ₹5,500 in year 2, ₹6,050 in year 3, and so on. Step-up SIP dramatically increases your final corpus because you invest more as your income grows.
Yes. SIP returns are taxable in India. For equity mutual funds: gains held less than 1 year are taxed at 15% (STCG). Gains held more than 1 year are taxed at 10% on gains above ₹1 lakh/year (LTCG). For debt mutual funds: gains are added to your income and taxed at your income tax slab rate. ELSS SIPs qualify for ₹1.5 lakh deduction under Section 80C.
Both involve fixed monthly investments. The key difference is that RD gives a fixed, guaranteed return (currently 6–7% at most banks), while SIP in equity mutual funds aims for higher returns (historically 10–12%) but with market risk. RD is safer; SIP has higher return potential over the long term.
In lump sum, you invest a large amount all at once. In SIP, you invest a fixed amount every month. SIP is better for regular income earners as it does not require a large sum upfront. SIP also reduces timing risk through rupee cost averaging — you buy more units when prices are low and fewer when prices are high.
