SIP Calculator
Project potential returns and maturity wealth from Systematic Investment Plans (SIP) in mutual funds.
About the SIP Calculator
The CalcNest SIP Calculator empowers you to simulate how small, disciplined monthly mutual fund investments can grow into substantial wealth over the long term. By taking advantage of compounding returns, even modest sums invested regularly can help fulfill life goals like retirement, higher education, or buying a home.
Mathematical Formula
Deterministic EngineFV = P × [((1 + r)^n - 1) / r] × (1 + r) Where P is the monthly investment amount, r is the periodic expected return rate (annual rate / 12 / 100), and n is the total number of monthly contributions.
Variables & Components
Worked Example: ₹5,000 Monthly SIP for 10 Years at 12% Expected Return
Investing ₹5,000 every month into an equity mutual fund delivering an average 12% annual compounding return over 10 years.
Step-by-Step Calculation
- 1 Monthly Periodic Rate: r = 12 / (12 × 100) = 0.01
- 2 Total contributions: 10 years × 12 months = 120 instalments
- 3 Total Principal Invested: 120 × ₹5,000 = ₹6,00,000
- 4 Compound Multiplier: [((1 + 0.01)^120 - 1) / 0.01] × (1 + 0.01) = 232.339
- 5 Maturity Corpus: ₹5,000 × 232.339 = ₹11,61,695
- 6 Estimated Wealth Gain: ₹11,61,695 - ₹6,00,000 = ₹5,61,695 (1.94x wealth multiplier)

The Compounding Curve: ₹10,000/Month at 12% p.a.
Albert Einstein famously referred to compound interest as the eighth wonder of the world. In the early years of a SIP, your invested principal forms the majority of your balance. But after 10 to 15 years, compounding gains dwarf your cumulative contributions:
| Duration | Total Amount Invested | Estimated Wealth Gains | Total Maturity Corpus | Wealth Multiplier |
|---|---|---|---|---|
| 5 Years | ₹6,00,000 | ₹2,24,864 | ₹8,24,864 | 1.37x |
| 10 Years | ₹12,00,000 | ₹11,23,391 | ₹23,23,391 | 1.94x |
| 15 Years | ₹18,00,000 | ₹32,45,760 | ₹50,45,760 | 2.80x |
| 20 Years | ₹24,00,000 | ₹75,91,480 | ₹99,91,480 | 4.16x |
| 25 Years | ₹30,00,000 | ₹1,59,76,351 | ₹1,89,76,351 | 6.33x |
Insight: Notice that between Year 20 and Year 25, your extra investment is just ₹6 Lakh, but your corpus expands by nearly ₹90 Lakh! That is pure compound momentum.
SIP vs. Lump Sum: Which Strategy is Best for You?
Systematic Investment Plan (SIP)
Ideal for salaried professionals receiving regular monthly income. Removes emotional biases, eliminates the anxiety of timing market peaks and troughs, and protects against bear market downswings through continuous rupee-cost averaging.
Lump Sum Investment
Optimal when you receive a sudden liquidity windfall (bonus, property sale, or inheritance) during market corrections. However, investing a lump sum right at an all-time market high exposes the portfolio to immediate drawdown risk.
