What is a SIP Calculator?
A SIP (Systematic Investment Plan) calculator estimates the future value of your regular monthly mutual fund investments based on your expected rate of return and investment horizon. Instead of investing a large lumpsum at once, SIP lets you invest a fixed amount every month — and the calculator tells you how much that disciplined habit will be worth over time.
This tool uses the standard SIP future value formula to give you an instant projection. You can tweak any of the three inputs — monthly amount, expected return rate, and duration — to compare scenarios and make informed investment decisions.
SIP Calculation Formula
The future value of a SIP is calculated using the following formula:
Where:
P = Monthly investment amount (₹)
r = Monthly rate of return = Annual rate / 12 / 100
n = Total number of months = Years × 12
FV = Future value of the investment
For example, if you invest ₹5,000 per month for 10 years at 12% p.a., the monthly rate r = 12/12/100 = 0.01, n = 120 months, and FV ≈ ₹11.62 lakhs.
How to Use This SIP Calculator
- Set your monthly investment: Use the slider or type directly in the input field. The range is ₹500 to ₹1,00,000 per month.
- Enter your expected return rate: This is the annual return you expect from your mutual fund. Equity funds have historically delivered 10–15% p.a. over the long term in India.
- Choose your investment period: Select how many years you plan to stay invested. Longer durations benefit more from compounding.
- Read the results instantly: The calculator shows your projected future value, total amount invested, and estimated wealth gained — with a doughnut chart for a visual breakdown.
Benefits of SIP Investing
- Rupee cost averaging: By investing a fixed amount regularly, you buy more units when markets are low and fewer when markets are high, automatically averaging your purchase cost over time.
- Power of compounding: Returns earned on your investments get reinvested, generating further returns. The longer you stay invested, the more dramatic this effect becomes.
- Financial discipline: SIP automates investing, removing the temptation to time the market or delay contributions. You invest consistently regardless of market conditions.
- Flexibility: You can start a SIP with as little as ₹500/month, increase or decrease the amount, pause, or stop at any time without penalty in most mutual fund schemes.
- No need to time the market: Because you invest fixed amounts at regular intervals, short-term market volatility works in your favour through cost averaging rather than against you.
