SIP Calculator – Calculate Mutual Fund Returns & Compound Interest
Systematic Investment Plan
Enter monthly amount, years, and expected return, then click "Calculate SIP".
Example: ₹5,000/month for 10 years at 12% → ₹11.62 Lakhs
The SIP Calculator estimates the future value of your monthly systematic investment plan (SIP) in mutual funds. It uses the power of compounding – the same principle behind a compound interest calculator. Whether you are planning for retirement, a child’s education, or a down payment, this investment calculator shows how small regular savings can grow into a large corpus. It can also be used as an RD calculator (Recurring Deposit) or FD calculator (Fixed Deposit) by entering the appropriate interest rate and tenure. Understanding your potential returns helps you make informed financial decisions.
SIP Formula & Compounding
M = P × ((1 + r)^n - 1) / r × (1 + r)
Where P = monthly investment, r = monthly rate of return, n = number of months.
For example, ₹5,000 per month for 10 years at 12% annual return (monthly rate 1%) grows to approximately ₹11.62 lakhs. Total invested is ₹6 lakhs, so estimated returns are ₹5.62 lakhs – the power of compounding in action.
Applications
Mutual fund planning: Estimate corpus for goal‑based investing.
Retirement planning: Calculate how much your monthly savings will grow.
Recurring Deposit (RD): Same formula, use bank RD rates.
Education / wedding funds: Plan regular contributions for future expenses.
Understanding the SIP Formula
The formula derives from the future value of an annuity due (payments at the beginning of each month). It accounts for the first month’s investment earning interest for all months, the second month for one month less, and so on. This is exactly how SIPs work in mutual funds when you choose the growth option.
If you want to calculate for a different frequency (quarterly, yearly), adjust the rate and number of periods accordingly.
Why SIP is a Powerful Investment Tool
Rupee cost averaging: Buy more units when markets are low, fewer when high.
Disciplined saving: Automatic monthly transfers build the habit of investing.
Power of compounding: Your returns earn returns, accelerating wealth creation.
Low entry barrier: Start with as little as ₹500 per month.
Common Mistakes to Avoid When Investing in SIPs
Many investors stop SIPs during market downturns – this defeats the purpose of rupee cost averaging. Also, choosing a very short tenure (less than 5 years) may not give compounding enough time to work. Our calculator helps you visualise the impact of longer tenures. Another mistake is expecting the same returns every year – equity returns vary, but over long periods (10+ years), historical averages have been around 10‑14%. Use a conservative estimate for planning, and be pleasantly surprised if returns are higher.
Use this SIP calculator as a compound interest calculator for any regular monthly investment. It is also helpful for comparing different mutual funds, planning your EMI capacity (reverse logic), or evaluating FD and RD returns. Bookmark it for your financial planning needs.

Frequently Asked Questions about SIP & Compounding
What is a SIP (Systematic Investment Plan)?
A SIP is a method of investing a fixed amount regularly (usually monthly) in mutual funds. It harnesses the power of compounding and rupee cost averaging.
How is SIP return calculated?
Our calculator uses the formula for future value of a series of monthly investments: M = P × ((1 + r)^n - 1)/r × (1 + r), where r is monthly rate of return, n is number of months.
Is this the same as a compound interest calculator?
Yes, SIP returns are based on compound interest. The calculator can be used as a compound interest calculator for regular monthly contributions.
Can I use this for RD (Recurring Deposit)?
Yes, the same formula applies to Recurring Deposits (RDs) offered by banks. Just enter the RD interest rate and tenure.
