SIP (Systematic Investment Plan) Calculator
Estimate the growth of your investments with regular SIP contributions over time
A Systematic Investment Plan (SIP) allows investors to build wealth gradually through regular, disciplined contributions. Unlike lump sum investing, SIPs benefit from rupee-cost averaging and the power of compounding over time, making them ideal for long-term financial goals. The performance of a SIP depends on contribution frequency, investment duration, expected return rate, and market volatility. Understanding how these factors influence your portfolio’s growth helps you plan smarter and stay consistent, even during market fluctuations. Whether you’re saving for retirement, education, or future milestones, evaluating potential returns through a SIP approach offers a balanced path toward financial security.

📊 SIP (Systematic Investment Plan) Calculator
Meet Arjun
Example Scenario
Arjun is a 27-year-old engineer who wants to start saving early for long-term goals like buying a home and early retirement. He decides to invest a fixed amount each month through a Systematic Investment Plan (SIP).
He enters his data into the SIP Calculator to estimate how much wealth he can accumulate with regular monthly investments and compounding growth:
| Detail | Amount |
|---|---|
| Total Contributions | ₹12,00,000 |
| Estimated Returns | ₹19,09,000 |
| Future Value | ₹31,09,000 |
➡️ Projected Wealth After 20 Years: ₹31,09,000
Seeing the result, Arjun realizes how starting early and staying consistent can lead to massive gains. He decides to automate his SIP and also increase his contribution by 10% annually to build even more wealth.
💡 With the calculator’s insights, Arjun now sees saving not as a burden, but as a powerful tool. He’s growing his money steadily with discipline — and securing his future without feeling the pinch.
How the SIP (Systematic Investment Plan) Calculator Works – Simple Math Explained
✅ 1. Enter Your Monthly Investment Amount
Start by entering how much you plan to invest every month into your SIP. This is your recurring contribution.
- Fixed monthly investment (e.g., ₹5,000 or $200)
- Choose an amount that fits your budget and savings goals
Formula:
Monthly SIP = Fixed Amount × Number of Months
✅ 2. Add Duration and Expected Return Rate
Next, specify how long you plan to continue investing and the average annual return you expect from the fund.
- Investment period in years
- Estimated return rate (e.g., 10–12%)
- Monthly compounding for mutual funds
Formula:
Future Value = SIP × {[(1 + r)^n − 1] × (1 + r)} ÷ r
Where r = monthly rate, n = total months
✅ 3. See Total Growth and Wealth Created
The calculator shows:
- Total contributions made
- Estimated interest earned
- Final maturity value of your investment
Formula:
Total Growth = Future Value − Total Contributions
💡 SIPs are one of the most disciplined ways to build wealth gradually. This tool shows how consistency, time, and compounding work together to help you achieve long-term financial goals.
Why SIP Returns Are Often Miscalculated — And How to Build Wealth Through Consistent Investing
Systematic Investment Plans (SIPs) are one of the most effective ways to invest regularly and build wealth gradually — especially in mutual funds. Yet, many investors misjudge their future corpus, miscalculate expected returns, or underestimate the power of consistency. Understanding how SIPs grow over time can help you align your contributions with long-term financial goals, no matter your starting point.
You Don’t Account for Compounding
SIPs grow not only from regular contributions, but also from the compound interest earned on past investments.
Fix it: Use the future value formula with monthly compounding to estimate long-term outcomes accurately.
You Rely on Unrealistic Return Assumptions
Assuming a flat 12% annual return every year may not reflect real market behavior.
Fix it: Base projections on historical averages, and model conservative, average, and optimistic return scenarios.
You Underestimate Time Horizon Impact
A few extra years of investing can dramatically increase your total corpus.
Fix it: Recognize the exponential impact of longer investment durations, even if monthly contributions stay the same.
You Don’t Factor in Step-Up SIPs
Many investors increase their SIP contributions annually but forget to model that growth.
Fix it: Use a step-up SIP strategy to reflect income growth and improve wealth accumulation without large upfront commitments.
You Ignore Inflation
A large corpus may seem impressive, but its purchasing power erodes over time.
Fix it: Calculate your real return (nominal return minus inflation) to set realistic expectations for future value.
You Stop During Market Volatility
Many investors pause SIPs when markets dip, losing out on lower purchase prices.
Fix it: Understand that market downturns benefit SIPs through rupee cost averaging — buying more units at lower prices.
You Don’t Reinvest Distributions
Distributions from mutual funds are often withdrawn instead of reinvested.
Fix it: Choose growth plans or reinvest income to maximize compounding and long-term returns.
💡 Final Thoughts
SIPs aren’t just about investing small amounts — they’re about building discipline, taking advantage of compounding, and growing wealth steadily over time. By modeling realistic returns, staying invested through cycles, and adjusting contributions as income grows, a SIP strategy can transform modest monthly savings into a meaningful financial future.
