FAQ
How is the lumpsum maturity calculated?
The amount is compounded annually at the expected return for the chosen years, so maturity equals amount times (1 + return) raised to the years.
Does the Lumpsum Investment Calculator send my data to a server?
No. The Lumpsum Investment Calculator runs entirely in your browser with JavaScript; the values you enter never leave your device and nothing is uploaded or saved.
Is a lumpsum better than an SIP?
Neither is universally better; a lumpsum exposes the full amount to the market immediately, while an SIP spreads entry points and averages cost over time.
Does this include any charges or taxes?
No. It projects gross compounding only; entry or exit loads, fund expenses, and taxes would reduce the actual maturity value.
