# Fixed deposit calculator

A fixed deposit calculator is a tool used to calculate the amount of interest earned on a fixed deposit investment. To use the calculator, you will need to input the following information:

- The amount of the initial deposit
- The interest rate offered by the bank or financial institution
- The duration of the fixed deposit investment

**The calculator will then provide you with the following information:**

- The maturity value of the fixed deposit investment
- The total interest earned on the investment
- The monthly interest earned (if applicable)

**The formula for calculating the maturity value of a fixed deposit is:**

**Maturity Value = P x (1 + (r/n))^(n x t)**

where: P = Principal amount r = Annual interest rate (as a decimal) n = Number of times the interest is compounded per year t = Time period of the investment in years

The formula for calculating the total interest earned on a fixed deposit is:

**Total Interest = Maturity Value – Principal Amount**

The formula for calculating the monthly interest earned on a fixed deposit is:

Monthly Interest = (Total Interest / Number of Months in Investment)
