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 Future Value Calculator.
What is Future Value?
The Future Value calculation tells you your future value from a few simple inputs. The figure you are solving for here is the future value, expressed in INR.
The Future Value formula
The core formula is:
Future value = Present value × (1 + Annual return rate ÷ 100)^(Number of years)Here is what each input means:
- Present value — a money amount. Example: ₹1,00,000.
- Annual return rate — a percentage, such as an annual rate. Example: 8%.
- Number of years — a value you set on the slider. Example: 10 years.
How to calculate it step by step
- Write down the present value (for example, ₹1,00,000).
- Write down the annual return rate (for example, 8%).
- Note the number of years (for example, 10 years).
- Apply the formula above to get your future value.
- Double-check the result with the Future Value Calculator.
Worked examples
Example 1
| Input / Output | Value |
|---|---|
| Present value | ₹1,00,000 |
| Annual return rate | 8% |
| Number of years | 10 years |
| Future value | ₹2,15,892 |
| Total growth | ₹1,15,892 |
With present value of ₹1,00,000, annual return rate of 8% and number of years of 10 years, the future value works out to ₹2,15,892.
Example 2
With present value of ₹2,00,000, annual return rate of 8% and number of years of 10 years, the future value works out to ₹4,31,785.
| Result | Value |
|---|---|
| Future value | ₹4,31,785 |
| Total growth | ₹2,31,785 |
Example 3
With present value of ₹50,000, annual return rate of 8% and number of years of 10 years, the future value works out to ₹1,07,946.
| Result | Value |
|---|---|
| Future value | ₹1,07,946 |
| Total growth | ₹57,946 |
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).
