Compound interest means that interest is calculated not only on the original principal but also on the interest accumulated during earlier periods.

In a Fixed Deposit, this happens when the interest earned is reinvested into the deposit instead of being paid out during the tenure. As the accumulated interest becomes part of the principal, the amount on which the next interest calculation is made increases.

A simple way to understand the difference is:

This is why understanding the interest payout option is just as important as looking at the Fixed Deposit interest rate.

The standard formula is:
A = P (1 + r/n)ⁿᵗ

Here, P is the principal, r is the annual interest rate, n is the number of compounding periods in a year and t is the tenure.

The illustration above uses the standard compound-interest formula. The actual maturity amount of a Fixed Deposit depends on the applicable terms and the Bank's calculation methodology.

Think of it this way. When you earn interest on a Fixed Deposit, you have two choices: receive that interest or let it stay in your deposit.
If you receive interest regularly, you can use it for your expenses.
If you let interest stay in your deposit, it becomes part of your money. The next time interest is calculated, you earn interest on this additional amount too.
Over time, this can help your deposit grow.

Cumulative or Regular Interest Payout?
The choice depends on how you want to use the interest you earn.

A regular payout can be useful if you need interest for everyday expenses. A Reinvestment Fixed Deposit may suit you better if you don't need interest immediately and want it to build up over time.
 

At DCB Bank, Fixed Deposit follows a quarterly compounding method.
The interest is calculated at the end of each quarter in a financial year and added to the principal. For the following quarter, interest is calculated on the original principal along with the interest accumulated during the earlier quarters.

A simple illustration of how the process works:
 

So, the interest earned in one period becomes part of the principal for the next quarter. That is what allows the interest itself to earn interest over the tenure.

DCB Bank also offers different interest payout options, depending on the Fixed Deposit selected. If you need regular interest during the tenure, you can choose an applicable payout option. If you prefer to let the interest accumulate until maturity, Fixed Deposit follows the compounding approach described above.

The interest rate matters, but there are a few other things to consider before putting your money into a Fixed Deposit.
●    Interest rate: How much interest will your deposit earn?
●    Tenure: How long do you want to keep your money in the deposit?
●    Interest payout: Would you like to receive interest regularly or get it along with your deposit at maturity?
●    Minimum deposit: How much money do you need to open the Fixed Deposit?
●    Other benefits: Are additional interest benefits or a loan against your deposit available to you?

Here's a quick look at some DCB Bank Fixed Deposit features:
•    Tenure: 7 days to 10 years
•    Minimum deposit: ₹10,000
•    Interest payout options: Monthly, quarterly, half-yearly, annually
•    Compounding frequency: Quarterly compounding
•    Senior citizens: Additional interest rate benefit
•    Loan/OD facility: Up to 80% of deposit value, subject to applicable terms

So, if you are looking for a high Fixed Deposit interest rate, it is worth looking beyond the rate alone and checking the tenure, payout option and applicable terms.

Compound interest simply means earning interest on the interest you've already earned.
In a cumulative Fixed Deposit, the interest earned is added back to the deposit. That increased amount then becomes the base for the next interest calculation.

The cycle continues.
For someone who does not need regular interest payouts and wants to accumulate the amount until maturity, this can make a cumulative Fixed Deposit an option worth considering.

If this is the kind of Fixed Deposit you are looking for, you can check the applicable rates and open a Fixed Deposit with DCB Bank.
