What is a Mutual Fund Returns Calculator?
A Mutual Fund Returns Calculator is an essential wealth planning tool that forecasts future capital accumulation and net gains for both Systematic Investment Plans (SIP) and Lumpsum Investments.
Mutual funds represent one of the most popular wealth-creation vehicles in India. Forecasting expected growth over 5, 10, or 20 years enables investors to plan retirement, children’s higher education, and financial freedom.
Mutual Fund Return Formulas
1. Lumpsum Compounding Formula
For a single one-time investment ($P$):
$$\text{Maturity Value (FV)} = P \times (1 + r)^n$$
2. Monthly SIP Annuity Formula
For monthly contributions ($P$) at monthly interest rate $i = \frac{\text{Annual Rate}}{12 \times 100}$ over $N$ months ($N = \text{Years} \times 12$):
$$\text{Maturity Value (FV)} = P \times \left[ \frac{(1+i)^N - 1}{i} \right] \times (1 + i)$$
Practical Worked Example: ₹5,000 Monthly SIP vs. ₹1 Lakh Lumpsum
Consider two investors over a 10-year period at an expected return rate of 12% p.a.:
- Investor A: ₹5,000 Monthly SIP
- Total Invested: ₹6,00,000
- Expected Maturity Corpus: ₹11,61,695
- Estimated Capital Gains: ₹5,61,695
- Investor B: ₹1,00,000 One-Time Lumpsum
- Total Invested: ₹1,00,000
- Expected Maturity Corpus: ₹3,10,585
- Estimated Capital Gains: ₹2,10,585
