How the Lumpsum Calculator Works
The lumpsum calculator applies compound growth to a single upfront investment amount over your chosen investment period, using your expected annual return rate.
Enter the amount you plan to invest as a lumpsum, the annual return rate you expect, and the number of years you intend to stay invested.
The results show your invested amount, the estimated returns generated, and the total value of your investment at the end of the period, along with a year-by-year growth breakdown.
Formula Used
The calculator uses the standard compound interest formula, compounded annually:
FV = P × (1 + r)^n- FVFuture value of your investment
- PLumpsum principal amount invested
- rExpected annual rate of return
- nInvestment period in years
Example Calculation
Suppose you invest a one-time amount for 10 years, expecting a 12% annual return.
- Total Investment₹1,00,000
- Expected Return Rate12% p.a.
- Investment Period10 years
- ResultTotal Value ≈ ₹3.11 Lakh (Invested: ₹1 Lakh, Returns: ₹2.11 Lakh)
Important Assumptions
- Returns are assumed to compound annually at a constant rate for the entire period — actual mutual fund returns are never fixed and fluctuate with the market.
- This calculator does not account for expense ratios, exit loads, or capital gains taxation.
- The invested amount is assumed to remain fully invested for the entire period with no partial withdrawals.
