Calculating your maturity value is straightforward once you know the Lumpsum formula and what each input means. This guide explains the method in plain language, walks through a manual calculation, and gives worked examples you can follow — then you can do it instantly with the Lumpsum Calculator.
What is Lumpsum?
The Lumpsum calculation tells you your maturity value from a few simple inputs. The figure you are solving for here is the maturity value, expressed in INR.
The Lumpsum formula
This calculation combines several inputs through a multi-step method rather than a single one-line formula. Enter the values below and the calculator resolves each step in order. The inputs it needs are:
- Total investment — a money amount. Example: ₹1,00,000.
- Expected return (p.a.) — a percentage, such as an annual rate. Example: 12%.
- Time period — a value you set on the slider. Example: 10 years.
How to calculate it step by step
- Write down the total investment (for example, ₹1,00,000).
- Write down the expected return (p.a.) (for example, 12%).
- Note the time period (for example, 10 years).
- Apply the formula above to get your maturity value.
- Double-check the result with the Lumpsum Calculator.
Worked examples
Example 1
| Input / Output | Value |
|---|---|
| Total investment | ₹1,00,000 |
| Expected return (p.a.) | 12% |
| Time period | 10 years |
| Maturity value | ₹3,10,585 |
| Invested amount | ₹1,00,000 |
| Estimated returns | ₹2,10,585 |
With total investment of ₹1,00,000, expected return (p.a.) of 12% and time period of 10 years, the maturity value works out to ₹3,10,585.
Example 2
With total investment of ₹2,00,000, expected return (p.a.) of 12% and time period of 10 years, the maturity value works out to ₹6,21,170.
| Result | Value |
|---|---|
| Maturity value | ₹6,21,170 |
| Invested amount | ₹2,00,000 |
| Estimated returns | ₹4,21,170 |
Example 3
With total investment of ₹50,000, expected return (p.a.) of 12% and time period of 10 years, the maturity value works out to ₹1,55,292.
| Result | Value |
|---|---|
| Maturity value | ₹1,55,292 |
| Invested amount | ₹50,000 |
| Estimated returns | ₹1,05,292 |
Tips for an accurate result
- Keep your units consistent — mixing, say, months with years or grams with kilograms is the most common source of error.
- Round only at the very end. Rounding inputs early can shift the final answer noticeably.
- Re-run the numbers whenever an input changes, rather than estimating from an old result.
- Annual rates must be converted to the period you are calculating for (for example, divide an annual rate by 12 for a monthly figure).
