Fixed Deposit (FD)- Meaning, Interest Rates, Types, Benefits & How to Open an FD Account

A fixed deposit is a financial product offered by banks, cooperative banks, non-banking financial companies (NBFCs) and post offices, where you deposit a lump sum for a fixed period and earn interest at a predetermined rate.
FDs are considered relatively safe because they are not affected by market volatalities, the returns are known and guaranteed. Moreover, bank deposits in India are insured up to ₹5 lakh per depositor per bank under the Deposit Insurance and Credit Guarantee Corporation (DICGC) scheme.
In this article, we explain fixed deposit meaning, interest rates, types, taxation, calculation methods, benefits and the how to open an FD account.
 

What Is a Fixed Deposit (FD)?

A Fixed Deposit (FD) is a savings instrument where a person deposits a fixed amount with a bank or financial institution for a predetermined period at a fixed interest rate.
Unlike savings accounts, the deposited money cannot usually be withdrawn before the maturity date without a penalty.
At the end of the tenure, the depositor receives-
  • The original deposit amount (principal)
  • The interest earned during the period
FD tenures generally range from 7 days to 10 years, depending on the bank or institution.
 

How Does a Fixed Deposit Work?

Here is a simple explanation of how a fixed deposit works,
1. Deposit amount - You invest a lump sum amount in an FD account.
2. Choose tenure -You select a fixed tenure, which can range from a few days to several years.
3. Interest rate- The bank or financial institution offers a fixed interest rate for the chosen period.
4. Interest accrual- Interest is calculated on the deposit amount and may be paid periodically or compounded.
5. Maturity - At the end of the tenure, you receive the principal amount along with the interest earned.
 

Fixed Deposit Interest Rates

FD interest rates depend on several factors, including-
  • The bank or NBFC offering the deposit
  • Deposit tenure
  • Deposit amount
  • Age of the depositor (senior citizens usually receive higher rates)
In India, FD interest rates generally range between 3% and 7.5% per year, although rates may change depending on market conditions.
Senior citizens often receive an additional interest rate benefit of around 0.25% to 0.75%.
Interest can be paid,
  • Monthly
  • Quarterly
  • Annually
  • At maturity (cumulative option)
Banks usually compound interest quarterly, although compounding frequency may vary between institutions.
NBFCs may sometimes offer slightly higher rates than banks, but investors should also consider the risk and credibility of the institution.
 

How Is FD Interest Calculated?

Fixed deposit interest is usually calculated using the compound interest formula.

Formula

A = P (1 + r/n)^(nt)
Where,
  • A = Maturity amount
  • P = Principal (deposit amount)
  • r = Interest rate per year
  • n = Number of times interest is compounded per year
  • t = Tenure in years

Example

Suppose you deposit ₹50,000 for 2 years at 6% interest, compounded quarterly.
Your maturity value will be calculated using the compound interest formula, resulting in a higher amount than simple interest because interest is earned on previously accumulated interest.
 

Types of Fixed Deposits

Banks and financial institutions offer different types of fixed deposits to suit different needs.
1. Regular fixed deposit - A standard FD available to all customers with fixed interest and tenure.
2. Senior citizen FD - Offers higher interest rates for individuals aged 60 years or above.
3. Cumulative FD - Interest is compounded and paid together with the principal at maturity.
4. Non-cumulative FD - Interest is paid periodically (monthly, quarterly, or yearly).
5. Tax saver FD - Offers tax deduction benefits under Section 80C of the Income Tax Act.
6. Special FD - Some banks introduce limited-period FDs with higher interest rates.
7. Floating rate FD - The interest rate may change based on market benchmarks.
8. NRI FD - Non-Resident Indians can open FDs such as
  • NRE fixed deposit
  • NRO fixed deposit
  • FCNR fixed deposit

5 Smart Financial Tips for Young Adults

Summary: Your 20s and 30s are a crucial time to start building a strong financial future. By making smart money decisions now, you can set yourself up for success later in life. In this blog post, we'll share five essential financial tips for young adults, including budgeting, saving, investing, and retirement. Money management secures your future, whether that's covering an unexpected bill or saving for a significant purchase. It involves budgeting, saving, and investing – essential skills for a stable financial future that are frequently overlooked in education. This blog will guide you through five practical financial tips that are simple to understand and apply. So, let's get started. Top 5 personal financetips for young adults Handling your money well is key—it's what keeps you secure when life throws surprises and helps you grow your savings for the future. It's about saving where you can, investing with a plan, and not spending more than what comes in. Nailing these basics can turn things around for you. So here they are, the top five financial tips for young adults: - Create a budget and track your expenses Budgeting is about tracking your income and expenses to make sure you spend less than you earn. It's creating a plan for your money, so you're in control of where it goes. Let's say you bring home INR 30,000 a month. You might allocate INR 10,000 for rent, INR 7,000 for food, and INR 3,000 for travel. Out of what’s left, you could put INR 5,000 into savings for emergencies or future goals, and the remaining INR 5,000 could cover your mobile plan, internet, or a weekend outing. This way, you've got your expenses covered, your savings on the rise, and still keep some money aside for leisure and unexpected needs. It's about making intentional choices so that you can balance today's needs with tomorrow's plans. - Start saving today Saving helps you build an [emergency fund](https://upstox.com/market-talk/emergency-fund-101-how-to-start-and-why-its-crucial-for-your-finances/), a cushion of money for unexpected expenses or emergencies. It also enables you to reach your short-term and long-term goals, like buying a car, going on holiday, or starting a business. A good rule of thumb is the 50/30/20 strategy. After you've covered your necessary expenses, 50% of your income, allocate 20% directly to your savings. For a monthly income of INR 30,000, that's INR 6,000 going into your savings each month. You can channel these funds into [mutual funds](https://upstox.com/learning-center/mutual-funds/the-basics-of-mutual-funds/), which often yield higher returns over time compared to a regular savings account. The remaining 30% of your income can then be used for discretionary expenses. By sticking to this rule, you automatically prioritise your financial future every month, steadily building a fund that can support big life events or tide you over during tough times. - Invest your money wisely Investing allows your money to actively work for you by acquiring assets that may generate income or appreciate over time. It's a handy way to grow your funds, beat inflation, and hit major milestones like buying a house, funding your studies, or setting up a cosy retirement. Take mutual funds, for instance. You can start small with SIPs from INR 500 and gradually build a mixed bag of investments. If you're not big on taking risks, a balanced mutual fund could be your thing, offering a steady blend of stocks and bonds. Make sure your investment picks match how much risk you're okay with, how long you plan to invest, and what you're hoping to achieve financially. - Plan your retirement ahead Retirement may feel like a dot on the horizon, but the earlier you begin, the better off you'll be. Consistently contributing a manageable amount, say INR 2,000, to a retirement plan like the [NPS](https://upstox.com/saving-schemes/nps-national-pension-scheme-india/), each month can amass a substantial sum over the years. This is where compounding comes into play – the interest you earn starts earning interest of its own, and over time, this growth accelerates. So, by starting in your 20s, you give your savings the longest possible time to expand, ensuring you a more comfortable and financially secure retirement. - Understand taxes Familiarising yourself with tax-saving opportunities, like investing in the [public provident fund (PPF)](https://upstox.com/saving-schemes/public-provident-fund-ppf-interest-rate/) and [equity-linked savings schemes](https://upstox.com/learning-center/mutual-funds/what-is-elss-and-how-to-invest-in-elss/) (ELSS) under Section 80C, can make a big difference to your finances. For those in a higher tax bracket, directing up to INR 1.5 lakh into a PPF can significantly cut your taxable income. This astute handling of taxes ensures you're not just meeting legalities but also retaining more income for your aspirations. Your best investment is in your financial education. Stay informed about financial products and market trends. This doesn't mean you need to become an expert overnight but understanding the basics of investments, insurance, and savings will help you make smarter decisions. Wrapping up: Key points to remember - Begin with small investments and increase over time, balancing risk with a mix of assets for long-term growth. - Small, regular contributions to a retirement fund can grow significantly, thanks to compounding interest. - Investing in options like PPF and ELSS can reduce taxable income and maximise savings.
