Lumpsum Calculator — Calculate One-Time Investment Returns
Got a year-end bonus, inheritance, property sale proceeds, or maturity of an old investment? Investing it as a lumpsum in mutual funds can grow it significantly over time. Our Lumpsum Calculator shows you exactly how much your one-time investment will grow to over any time period at any expected return rate.
Enter the lumpsum amount, expected annual return, and tenure. Get the maturity value, total gains, and a year-by-year growth table. No signup, no cost.
How to Calculate Lumpsum Returns
1. Investment Amount
Enter the one-time amount you want to invest — a bonus, inheritance, or maturity proceeds.
2. Expected Return
Enter the annual return you expect — for example 12% for an equity fund or 7% for a debt fund. These are assumptions, not guaranteed returns.
3. Investment Period
Enter how many years you'll stay invested. Longer tenures dramatically improve compounded returns.
4. View Maturity
See the estimated maturity value and total gains, and follow the growth year by year in the table.
