How the lumpsum calculator works
A lumpsum (one-time) investment puts the full amount to work on day one. Returns compound each year: you earn on both the principal and earlier gains.
This is the standard future-value approach used for mutual fund lumpsum plans in India and for one-time investments elsewhere. Change the currency in your head - the formula stays the same.
P = principal • r = expected annual return • n = years
How to use this calculator
- Enter the one-time amount you plan to invest.
- Set an expected annual return that matches the risk level you are comfortable with.
- Choose the number of years and review future value, wealth gained and absolute return.
Worked example
Example: ₹5,00,000 at 12% for 10 years grows to about ₹15,52,924 before costs and tax.
