Overview & Application
A Systematic Investment Plan (SIP) is one of the most effective strategies to build long-term wealth through rupee/dollar cost averaging and compounding interest. By investing a fixed sum on a monthly recurring basis into index funds, mutual funds, or equities, investors mitigate market timing risks while enjoying exponential compounding over decades. This SIP Calculator illustrates how small monthly deposits compound into life-changing portfolios.
How to Use the SIP Calculator
- Enter your planned monthly investment amount.
- Specify your expected annual return rate (historical equity index averages range between 10% to 15%).
- Select your investment horizon in years (e.g. 5, 10, 20, or 30 years).
- Optionally configure an annual Step-Up percentage to simulate annual salary raises.
- Analyze the maturity amount, total principal invested, estimated capital gains, and visual growth charts.
Compound Interest SIP Maturity Formula
SIP returns leverage compound interest applied to recurring annuity payments at the end of every compounding cycle.
Real-World Calculation Scenarios
10-Year Long Term SIP ($500/month @ 12%)
Scenario: Investing $500 monthly for 10 years at an expected 12% annual return.
Principal Invested = $500 × 120 = $60,000. Maturity Value = $116,170. Wealth Gain = $56,170.
Result: Your wealth nearly doubles, with gains representing 48.3% of the final portfolio.
25-Year Retirement SIP ($1,000/month @ 12%)
Scenario: Investing $1,000 every month for 25 years with uninterrupted compounding.
Total Invested = $300,000. Total Maturity Amount = $1,897,635. Wealth Gain = $1,597,635.
Result: 6.3x total return on investment! Compound interest generates over $1.5 million in pure passive gains.
