**How does the IDBI Bank FD Calculator Work?**

An individual needs to enter a few details to arrive at his/her return on investment from the fixed deposit. Such a calculator works on the following formula –

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

Where,

- A is the maturity amount
- P is the initial sum of investment
- r is the annual rate of interest
- n refers to the number of times that interest applied is compounded
- t is the maturity period

**Example of IDBI FD Calculation**

To understand fixed deposits better, one can refer to the example of Mr. Rao’s FD investments below –

Mr. Rao, a 52-year old employee of a private organization, decided to invest Rs.3 lakh for a tenure of 5 years. After consulting the table above, it is clear that he is eligible for returns of 5.9% per annum. Further, he picks half-yearly compounding interest for the FD. In this case, the parameters for IDBI FD calculator 2020 are as follows –

P = Rs.3 lakh

r = 5.9/100 = 0.059

t = 5 years

n = 2

Thus, placing these figures in the given formula –

A = 3,00,000 (1+0.059/2)^2 x 5

A = Rs.4,01,222

Therefore, the interest earned on deposit (I) is derived from the equation I = A-P

I = Rs.401222 – Rs.300000

I =Rs.101222

An IDBI FD interest rates calculator uses this same equation to determine profitability from fixed deposit investment. Nevertheless, the tool accelerates the calculation process significantly, ensuring faster and more accurate results.

**How do Various Factors Affect FD Interest Earnings?**

Nevertheless, due to the compound rate of interest calculation, individuals planning to deposit for the long-term can avail more benefits.

**Rates of interest**
