Understanding Fixed Deposit (FD): How It Works and Its Interest Mechanism

Fixed deposits (FDs) are one of the most popular, safe, and reliable investment options offering guaranteed returns to individual investors. Also, they are considered a risk-free investment tool and thus preferred over other investment avenues. In this post, we will talk about the ins and outs of fixed deposits (how fixed deposits work), different types of fixed deposits available, eligibility, interest mechanism, and comparison with other investment options. We will also address the common question, “What is the meaning of FD?” and “How do fixed deposits work?”.

How Fixed Deposits (FD) Work

They accept a fixed deposit, a certain sum of money is deposited for a fixed period of time. The bank guarantees a fixed rate of interest on that sum which makes it easy to plan and calculate. Normally, the higher the tenure the higher the rate of interest.

How To Open A Fixed Deposit

Opening a fixed deposit account is generally very simple. Here are the steps:

  1. Select the bank and the tenure that you want the deposit with.
  2. Deposit the Amount. After the decision regarding the tenure (which varies from a month to five years), deposit the money in question in the account.
  3. You wait till maturity, unless interest is payable on a periodic basis.
  4. Receive the Interest: "All fixed deposit accounts are thus: at the end of your year, you will get back your original RM10,000 deposit plus your RM300 interest."

All about fixed deposits terms and conditions:

  • Interest Rate: This parameter is fixed at the time of deposit and does not change during the tenure.
  • Tenure: The duration of the fixed deposit is normally predetermined - from a few months to up to five years.
  • Withdrawal or Closure: With many higher interest saving accounts, you don’t have the liberty of easily accessing your money. If you withdraw your money too soon, you could lose all or some of your interest. Hence before you lock in your money make sure you don’t need it for anything soon.

Types of Fixed Deposit Accounts

There are several types of fixed deposit accounts available, each designed to cater to different needs and preferences.

Short-Term vs. Long-Term Fixed Deposits

A fixed deposit (FD) is a type of financial investment that has a set maturity period and earns a fixed interest rate. Short-term FDs usually range in tenure from one month to a year. At the end of this period the principal and accrued interest is paid out. Short-term FDs generally pay lower interest rates, although they provide better liquidity. Long-term fixed deposits pay better rate of returns and are suitable for investing in lumpsum for the long-term, without recourse to capital for an extended time.

Example: you select a 12 month fixed deposit with a 2.5% p.a. interest rate and will earn interest to a predictable timetable, however, if you need cash before the 12 months is up ’breaking’ the investment means penalties could apply.

Islamic Fixed Deposits and Other Variants

Islamic fixed deposits are created in accordance with the tenets of Shariah law, which bans earning of interest (riba). The returns are therefore not the interest component as in the conventional manner, but the profits made from the selling of the commodities in keeping with the modes of Islamic finance, e.g. Murabahah.

There are also special fixed deposit accounts provided by banks like foreign currency deposits and junior fixed deposits for children, further, senior citizens also have the benefit of special fixed deposit products with higher interest rates and early withdrawal access without penalties.

Interest Mechanism in Fixed Deposits

One of the attractive components of fixed deposits is the interest mechanism is a simple one that is designed to offer a regular mechanism for earning fixed and reliable returns.

How Fixed Deposit Works and Interest calculation

When you deposit money with the bank in a fixed deposit, the bank calculates the interest that is payable to you based on the sum that you deposited (known as the “principal”), the interest rate that you agreed to, and the period of deposit (known as tenure). For example, let’s say you placed your money, RM10,000.00 at an interest rate of 3% a year for 1 year. The interest shall be:

Interest = Principal × Interest Rate × Tenure

Interest = 10,000 × 3% × 1 = 300 RM

At the end of the year, you receive 10,300 RM back, which is your original deposit plus interest.

Is interest on fixed deposit debit or credit?

Usually the interest earned on fixed deposits is credited back into your account after the end of the tenure, or at periodic intervals within that tenure, depending on the type of fixed deposit and the interest rate applied to it. Certain banks arrange for the interest to be debited to your savings account on a monthly or quarterly basis, while some pay all at once when the time period for the fixed deposit has expired.

Tip: Search for a fixed deposit that pays interest every month or every quarter to boost your monthly income. If you are willing to wait till maturity for your returns, search for a fixed deposit which pays interest at maturity.

Advantages and Disadvantages of Fixed Deposits

While fixed deposits have their share of advantages, they also come with their own set of disadvantages.

Advantages

  • Low risk: Fixed deposits are among the least risky investments available to you. Your returns are guaranteed and your principal is safe.
  • Guaranteed returns: investors are notified precisely how much returns will be made, thus fixed deposit accounts are suited for less daring investors.
  • Insurance: the deposits are covered by PIDM in Malaysia, and so on.

Disadvantages

  • Low Liquidity: Fixed deposits tie up your money for a specified term; accessing cash before that term ends can be costly.
  • Lower Returns Compared to Stocks or Bonds: Generally, the interest rate is less exciting than what you might find earning in stocks or bonds.

Fixed Deposit vs. Savings Accounts

Both fixed deposit and savings accounts let you save your money, albeit in different ways.

  • Interest Rates: Fixed deposit accounts come with much higher interest rates (1.5% to 2.5% per annum) when compared to savings accounts (0.2% to 1.5%).
  • Liquidity: You will also not be able to withdraw from a fixed deposit anytime you want like a savings account. Instead, you will have to lock the money in for a certain tenure.
  • Safety: Both are safe, but fixed deposits typically have better insurance.

Tip: If you want to earn more interest but still have easy access to your funds, think about putting money into both a fixed deposit and a savings account.

FAQ

Sure, here are your questions answered.

What is the difference between FD and savings account?

The primary difference is in the interest rate. Fixed deposits earn greater interest but require you to tie up your money for a specified period. Savings accounts earn less interest and offer greater flexibility for withdrawals.
