How does the IDBI Bank FD Calculator work?

Using these just needs to give a few details to know the return amount on the deposit. The details might include the principal amount, tenure period, and he/she should be aware of the interest rates offered. It is calculated using a formula:

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

A-Maturity amount

P-Principal amount or sum of investment

R-Interest rate per year

N-Number of times the interest applied is compounded

T-Maturity period

IDBI Fixed Deposit calculator uses the same formula, but it saves time using this, and there is little scope of error in calculation.

Many factors affect the returns on an amount deposited:

Term of investment-Choosing the correct maturity term is significant to yield more interest. IDBI Fixed Deposits are beneficial both short-term and long-term, but since the compound rate of interest calculation is applied here; it is more beneficial for long-term investments.

Principal amount -If the amount invested is maximized, it can achieve more returns.

Interest rate-If the principal amount and tenure period are kept constant; the interest rate will determine the return amount. The more the interest rate, the more will be the return amount. IDBI Bank FD Calculator helps compare different interest rates.

Interest Compounding Frequency-This is the frequency at which interest is compounded. It can be monthly, quarterly, half-yearly, or yearly. The more the compounding frequency, the more the investor earns on the deposit.

TDS Applicability and TDS Rate-(Tax Deducted at Source) is how the bank deducts from the interest income and remits it to the central government. It is set at an average of 10%.

Simple Interest vs. Compound Interest

With simple interest, the interest is only earned on the principal amount, whereas with compound interest, the interest is earned on the principal and the interest.

Simple interest is calculated by the formula:

SI= (P*r*t)/100


P- Principal amount

r- Rate of interest

t- Time period

In compound interest, you earn interest on the principal amount, and you earn interest in interest. But one should make sure the interest rate is reasonable and see how many times interest will apply on interest in a year; that is, the number of times interest is compounded.

Compound interest is calculated by:

For example, the bank offers 8% per annum for a five-year deposit, and the interest is compounded annually. And if the amount invested is Rs. 10,000

Year 1


This is added to the principal amount, which makes it Rs.10, 800.

Year 2

You will earn interest on Rs.10, 800


This is again added back, which makes it Rs.11, 644.

The formula is:

CI=P {(1+i/100)n-1}

Where P-Principal amount

N-Number of years

I-Interest rate

How to use the IDBI Bank FD Calculator?

One has to enter a few basic details, and the calculator does the job.

  • Customer type-new/ existing customer/senior citizen.
  • Type of fixed deposit- cumulative or non-cumulative.
  • Amount to be invested.
  • Tenure period.
  • This helps you compare the different returns one can get on the same investment amount from different banks.

Factors affecting FD Rate of Interest

There are a few other factors that might affect the rate of interest that is beyond the control of the investor.

  • Recession-This causes the economy to slow down. So the RBI (Reserve Bank of India) increases the supply of money in the market, which subsequently lowers the interest rate on cash deposits.
  • Inflation- This leads to a decrease in the value of the currency or rupee and the purchasing power. In this case, to compensate for the losses the bankcollects more cash by increasing the interest rate.
  • Reserve Bank of India (RBI)- It is the central authority of India that regulates all the monetary policies across the country. This body exercises maximum control and keeps a record of the flow of funds in the country. The regulations released by this have an impact on interest rates.
FD interest have fallen consistently over the last 5 years.

The IDBI FD calculator helps calculate the interest that will be generated even before investing. What should be kept in mind is to check the table of interest rates with the bank. Fixed deposits are all about minimizing risk and guaranteed returns.

  • Q1. Is premature withdrawal possible?

    A1. Yes, it is possible to withdraw your money before the maturity period is completed, but it might affect the returns. Moreover, there is a one-year lock-in period where no withdrawal is possible.

    After this, the premature withdrawal charges may apply, which will be the average benchmark rate of the immediately preceding quarter with the markup of the applicable preceding term.

  • Q2. What are the minimum and maximum amount required to open an FD account in IDBI bank?

    A2. You can open an account with a mere Rs. 10,000. There is no upper limit in investing in IDBI Fixed Deposit.

  • Q3. How many years will it take for the amount to get doubled in IDBI Fixed Deposit?

    A3. This is calculated using the rule of 72. One needs to know the interest rate for this. Considering the interest rate to be 6.95%, divide 72 by the interest rate. So, in this case, 72/ 6.95= 10.36

    So it will take a little over 11 to 14 years for the amount to double, considering the 10% tax deduction. 

  • Q4. What are the minimum and maximum term of deposit?

    A4. The minimum term of the deposit is 15 days, and the maximum is up to 20 years. However, it is advisable to opt for long-term investment considering the compounding of interest rates. 

  • Q5. Can a minor open an FD account?

    A5. A guardian can open a joint account with the minor on his/her behalf. The minor will receive the earning of the FD once he is 18 years or whenever the FD matures (whichever comes earlier). Till that time, the guardian remains in charge of the account. 

  • Q6. Is it possible to get a loan against a Fixed Deposit?

    A6. Yes, it is possible. It is a secured loan that you take by pledging the fixed deposit as the collateral. You don't have to break the Fixed Deposit to take a loan against it. No credit score check is required to take a loan against Fixed Deposit. All Fixed Deposit holders, including joint account holders, can apply. Minors are not eligible to apply for this. Investors of a 5-year tax-saving FD cannot apply for this. Loans are offered at a lower interest rate. 

  • Q7. Is the interest earned on Fixed Deposits taxable?

    A7. Yes, it is. As per the Income Tax Act, when the interest earned in the financial year exceeds Rs.40, 000, Tax Deductible Source is applicable on the credited interest.

    However, one can claim tax deductions up to Rs.1.5 lakh per financial year. There are tax-saving FD schemes also available. But it does not apply to senior citizens since the interest rate is already high.
