Calculating your maturity value is straightforward once you know the FD 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 FD Calculator.
What is FD?
The FD 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 FD 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:
- Deposit amount — a money amount. Example: ₹1,00,000.
- Interest rate (p.a.) — a percentage, such as an annual rate. Example: 7%.
- Tenure — a value you set on the slider. Example: 5 years.
- Compounding frequency — one of: Yearly, Half-yearly, Quarterly, Monthly. Example: Quarterly.
How to calculate it step by step
- Write down the deposit amount (for example, ₹1,00,000).
- Write down the interest rate (p.a.) (for example, 7%).
- Note the tenure (for example, 5 years).
- Choose the compounding frequency (for example, Quarterly).
- Apply the formula above to get your maturity value.
- Double-check the result with the FD Calculator.
Worked examples
Example 1
| Input / Output | Value |
|---|---|
| Deposit amount | ₹1,00,000 |
| Interest rate (p.a.) | 7% |
| Tenure | 5 years |
| Compounding frequency | Quarterly |
| Maturity value | ₹1,41,478 |
| Principal | ₹1,00,000 |
| Interest earned | ₹41,478 |
With deposit amount of ₹1,00,000, interest rate (p.a.) of 7%, tenure of 5 years and compounding frequency of Quarterly, the maturity value works out to ₹1,41,478.
Example 2
With deposit amount of ₹2,00,000, interest rate (p.a.) of 7%, tenure of 5 years and compounding frequency of Quarterly, the maturity value works out to ₹2,82,956.
| Result | Value |
|---|---|
| Maturity value | ₹2,82,956 |
| Principal | ₹2,00,000 |
| Interest earned | ₹82,956 |
Example 3
With deposit amount of ₹50,000, interest rate (p.a.) of 7%, tenure of 5 years and compounding frequency of Quarterly, the maturity value works out to ₹70,739.
| Result | Value |
|---|---|
| Maturity value | ₹70,739 |
| Principal | ₹50,000 |
| Interest earned | ₹20,739 |
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).
