SIP Calculator
Project monthly investment growth with conservative, moderate, and aggressive return assumptions.
What is sip?
A SIP (Systematic Investment Plan) is a method of investing a fixed amount regularly into mutual funds, typically on a monthly basis.
SIPs allow you to invest small, fixed amounts at regular intervals regardless of market conditions. This approach benefits from rupee cost averaging, where you buy more units when prices are low and fewer when prices are high. Over time, the power of compounding significantly grows your investment. SIPs are ideal for long-term financial goals like retirement, children's education, or wealth creation because they instill financial discipline and reduce the impact of market volatility.

Formula
Where M = Maturity value, P = Monthly investment amount, i = Monthly rate of return (annual rate ÷ 12 ÷ 100), and n = Total number of months invested. This formula calculates the future value of a series of regular investments with compound returns. Each monthly contribution starts compounding immediately, and the longer your investment horizon, the more dramatic the compounding effect.
Real-Life Examples
Early Starter Advantage
Ravi starts investing $200/month at age 25 with 12% annual returns. By age 50 (25 years), he has $378,000. Total invested: $60,000. Returns: $318,000. Starting 10 years earlier than his friend yields 3x more wealth.
Moderate Investor
Sarah invests $500/month for 15 years at 10% returns. Total invested: $90,000. Maturity value: $207,000. Returns: $117,000. Her returns exceed her total investment by 30%.
Goal-Based SIP
Priya needs $50,000 for her child's education in 10 years. At 12% annual returns, she needs to invest $215/month. If she waits 5 years, she'd need $600/month for the remaining 5 years — nearly 3x more per month.
Step-by-Step Calculation
$300/Month SIP for 20 Years at 12%
- P = $300 (monthly investment)
- Annual return = 12%, so i = 12/12/100 = 0.01 (monthly rate)
- n = 20 × 12 = 240 months
- (1 + i)^n = (1.01)^240 = 10.89
- [(1.01)^240 - 1] / 0.01 = 989
- M = 300 × 989 × 1.01
- M = $299,667
- Total invested = $300 × 240 = $72,000
- Returns = $299,667 - $72,000 = $227,667
Maturity Value: $299,667 | Returns: $227,667 (316% gain)
Pros and Cons
Advantages
- ✓Rupee cost averaging reduces market timing risk
- ✓Starts with small amounts — accessible to all income levels
- ✓Power of compounding grows wealth exponentially over time

Financial Strategies
Start Early, Even with Small Amounts
Time is more important than amount in SIP investing. $100/month starting at 25 beats $300/month starting at 35, thanks to compounding.
Increase SIP by 10% Annually
As your income grows, increase your SIP contribution by 10% each year. This 'step-up SIP' can double your final corpus compared to a fixed SIP.
Diversify Across Fund Types
Don't put all your SIP in one fund. Spread across large-cap, mid-cap, and sectoral funds for balanced risk and return.
Stay Invested Through Market Downturns
Market dips are opportunities for SIP investors — you buy more units at lower prices. Staying invested through volatility maximizes long-term returns.
Common Mistakes to Avoid
✗ Stopping SIP during market downturns
✓ Market dips are the best time for SIP — you buy more units at lower prices. Stopping locks in losses and misses recovery.
✗ Choosing funds based only on past returns
✓ Past performance doesn't guarantee future results. Consider fund consistency, expense ratio, fund manager track record, and investment philosophy.
✗ Not increasing SIP with income growth
✓ Increase your SIP by 10-15% annually as your salary grows. This dramatically boosts your final corpus.
✗ Investing in too many funds
✓ 4-6 well-diversified funds are sufficient. Over-diversification dilutes returns and makes portfolio management difficult.
✗ Ignoring expense ratios
✓ A 1% difference in expense ratio can reduce your final corpus by 20-25% over 20 years. Choose low-cost index funds where possible.
Expert Tips
- 💡Use the Rule of 72 to estimate doubling time: divide 72 by your expected annual return rate.
- 💡Direct plans have lower expense ratios than regular plans — always choose direct if investing yourself.
- 💡Set your SIP date right after your salary day to ensure consistent investing.
- 💡Review your SIP portfolio annually and rebalance if any fund consistently underperforms its benchmark.
- 💡Consider a mix of equity (for growth) and debt (for stability) SIPs based on your risk tolerance and investment horizon.

What is a SIP?
A SIP (Systematic Investment Plan) is a method of investing a fixed amount regularly into mutual funds, typically on a monthly basis. SIPs allow investors to start with small amounts (as low as $10-50/month) and build wealth systematically over time. The key benefits are rupee cost averaging (buying more units when prices are low) and the power of compounding (returns generating their own returns).
SIP Calculation Formula
M = P × ({[1 + i]^n - 1} / i) × (1 + i), where M = Maturity value, P = Monthly investment amount, i = Monthly rate of return (annual rate ÷ 12 ÷ 100), and n = Total number of months invested. This formula calculates the future value of a series of regular investments with compound returns.
Benefits of SIP Investing
- •SIPs offer multiple advantages: (1) Rupee cost averaging reduces market timing risk, (2) Start with small amounts—accessible to all income levels, (3) Power of compounding grows wealth exponentially over time, (4) Instills financial discipline through automatic investments, (5) Flexible—can increase, decrease, pause, or stop anytime.
SIP vs Lump Sum Investment
SIPs are better for investors who want to reduce timing risk and build discipline. Lump sum investments can yield higher returns if timed correctly at market lows, but they carry higher risk. SIPs are generally recommended for most retail investors because they eliminate the need to predict market movements.
How to Start a SIP
- •Steps to begin SIP investing: (1) Define your financial goal and time horizon, (2) Assess your risk tolerance (conservative, moderate, aggressive), (3) Choose fund types based on goal and risk (equity for long-term, debt for short-term), (4) Select direct plans (lower expense ratios), (5) Set SIP amount and date (preferably after salary day), (6) Monitor annually and rebalance if needed.
Common SIP Mistakes
Stopping SIP during market downturns (dips are opportunities to buy more units at lower prices). Choosing funds based only on past returns (past performance doesn't guarantee future results). Not increasing SIP with income growth (step-up SIP by 10% annually). Investing in too many funds (4-6 well-diversified funds are sufficient). Ignoring expense ratios (1% difference can reduce final corpus by 20-25% over 20 years).
