How is SIP Calculated?
A Systematic Investment Plan (SIP) involves making consistent investments at regular intervals, typically monthly. Because the investment is spread over time, the calculation utilizes the future value of an annuity formula rather than standard lump-sum compounding math.
The exact mathematical formula used by our calculator is: FV = P × [ (1 + i)^n - 1 ] / i × (1 + i)
- FV: Future Value (Maturity Amount)
- P: SIP Investment Amount per month
- i: Monthly Rate of Return (Annual Rate % / 12)
- n: Number of total months you will invest
Power of Compounding in Mutual Funds
Mutual funds generate returns which are then automatically reinvested. This creates a snowball effect where you earn returns on your initial principal plus all the accumulated returns from previous months.
When you invest via SIP for long horizons (15-20 years), the "Est. Returns" portion will eventually overtake your "Invested Amount", generating massive wealth without any extra capital input. Our visual progress bar clearly illustrates this exact tipping point.
Why Systematic Investment Plans (SIP) are best for Long-Term Wealth
Rupee Cost Averaging
By investing a fixed amount every month, you automatically purchase more mutual fund units when the market is down and fewer units when the market is up. This completely removes the stress of trying to "time" the market and averages out your purchase cost over time.
Financial Discipline
SIPs force you to save consistently. Because the amount is auto-debited from your bank account every month before you get a chance to spend it, you build excellent financial habits passively.
Flexibility and Convenience
You can start a SIP with as little as ₹500 a month and increase, pause, or stop it at any time without massive penalties (unlike traditional insurance endowments or physical real estate).
