A lumpsum calculator is a financial tool used to estimate the maturity value of a one-time investment over a selected time period. Investors commonly use this calculator while planning long-term financial goals such as retirement, education planning and wealth creation.
The calculator uses the principles of compound growth to estimate how an investment may grow over time based on an assumed annual rate of return.
For example, a one-time investment of ₹20 lakh for 10 years at an expected annual return of 12% is estimated to grow to approximately ₹62.11 lakh over the investment period.
When the above figures are entered into a lumpsum calculator, the estimated future value of the investment after 10 years comes to approximately ₹62.11 lakh, assuming an annual return rate of 12% and yearly compounding.
| Particulars | Value |
| Invested Amount | ₹20,00,000 |
| Investment Duration | 10 Years |
| Expected Rate of Return | 12% |
| Estimated Returns | ₹42,11,696 |
| Total Estimated Value | ₹62,11,696 |
