Formula used
For SIP: FV = monthly investment × [((1 + monthly return)^months - 1) / monthly return] × (1 + monthly return). For lumpsum: FV = principal × (1 + annual return)^years.
Example calculation
A ₹10,000 monthly SIP for 10 years at 12% gives an estimated future corpus based on monthly compounding.

How does a mutual fund calculator work?
Estimates how investments may grow using SIP, lumpsum, or SWP inputs.
SIP vs lumpsum: which is better?
SIP reduces timing risk through rupee-cost averaging. Lumpsum suits windfalls or market dips.
Ideal investment horizon?
Equity MF: 7-10+ years. Debt MF: 1-3 years. Hybrid: 3-5 years.
How does inflation affect returns?
If inflation is 6% and return is 12%, real return is ~6%.
