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 disciplined method of investing a fixed sum of money at regular intervals (typically monthly) into mutual funds, taking advantage of compounding and rupee cost averaging.
How is SIP return calculated?
Our calculator uses the annuity due compound formula: M = P × ((1 + r)^n - 1) / r × (1 + r), where P is monthly deposit, r is monthly return rate, and n is number of months.
Is a SIP calculator the same as a compound interest calculator?
Yes. SIP returns are driven by monthly compound interest. The calculator models compounding wealth creation over multi-year investment horizons.
What is Rupee Cost Averaging in SIPs?
Rupee cost averaging means buying more mutual fund NAV units when market prices drop and fewer units when prices rise, reducing your average cost per unit over time.
Can I use this calculator for Recurring Deposits (RD)?
Yes. Bank Recurring Deposits use the exact same mathematical formula. Simply input your bank's annual RD interest rate and tenure.
What expected annual return should I assume for equity SIPs?
Historically, broad-market equity mutual funds in India have delivered 12% to 15% CAGR over 10+ year periods. Conservative debt funds yield 6% to 8%.
Is SIP better than Lumpsum investment?
SIP is better for volatile markets and regular earners as it mitigates market-timing risk. Lumpsum is superior in strong bull markets when capital is available upfront.
Are SIP returns taxable upon redemption?
Equity mutual fund gains held over 1 year are taxed as Long Term Capital Gains (LTCG) at 12.5% above ₹1.25 lakh profit per financial year. Short-term gains are taxed at 20%.
