Let's start with something that might surprise you. Despite every new investment product that's come along — SIPs, ULIPs, REITs, sovereign gold bonds — the fixed deposit remains one of the most widely held financial instruments in India. Tens of thousands of households, from first-time savers to seasoned investors, keep a portion of their money in FDs. And not because they're unaware of other options.
It's because an FD does something most investments don't: it tells you, on day one, exactly what you'll get back and when. In a world of fluctuating NAVs and unpredictable markets, that kind of certainty has real value.
This guide covers everything — how fixed deposits work, the different types, what drives your interest rate, how to actually calculate your returns, what happens if you need the money early, and how to invest smarter using a strategy called FD laddering. Whether you're opening your first FD or revisiting your existing portfolio, this should answer every question you have.
What Is a Fixed Deposit?
A fixed deposit is a financial instrument where you deposit a lump sum of money with a bank or Non-Banking Financial Company (NBFC) for a specific period — the tenure — at a fixed rate of interest. The rate is decided at the time of booking and doesn't change during the tenure, regardless of what happens to interest rates in the broader economy.
At the end of the tenure, you get your original deposit back along with the interest earned. That's the whole thing. No market monitoring, no fund manager decisions to track, no NAV calculations.
What makes FDs particularly useful is their predictability. If you're saving for something specific — a child's education three years from now, a home renovation, a retirement corpus — an FD lets you work backwards: choose the rate, choose the tenure, and the maturity amount is known in advance.
How FD Interest Is Calculated
Your FD earns interest in one of two ways, simple or compound. Which one applies depends on whether you take your interest out regularly or leave it to grow. Here is how each works in general, and then how Shriram Finance applies it to your deposit.
Simple interest: you earn on your original deposit only
Simple interest is calculated on your principal alone, and the base never grows. Many institutions use this method to work out payouts on non-cumulative FDs, where you receive interest at regular intervals instead of at maturity.
The formula is:
Interest = (P × R × T) / 100
Here, P is your principal (the amount you deposit), R is the annual interest rate as a percentage, and T is the tenure in years. The rate is quoted as p.a. (per annum, meaning for each year).
If you deposit ₹1 Lakh* at 7%* p.a. for 1 year*, your interest is ₹7,000*. That figure stays the same every year because the base never changes.
Compound interest: your interest starts earning interest
Compound interest is added to your principal at the end of each compounding period. The next period's interest is then calculated on that larger amount. Cumulative FDs work this way, because you leave the interest in the deposit and receive everything at maturity.
The formula is:
Maturity amount = P × (1 + R / (100 × N))^(N × T)
Here, N is the number of times interest compounds in a year: 1 for annual, 2 for half-yearly, 4 for quarterly and 12 for monthly. Your interest is the maturity amount minus your principal.
The more often interest compounds, the more you earn. Here is ₹1 Lakh* deposited for 4 years* at 7%* p.a.:
The gap grows as your deposit and tenure increase.
How Shriram Finance calculates your FD interest
Shriram Finance compounds interest monthly on both cumulative and non-cumulative FDs. What changes is what happens to that interest.
Cumulative FD. Each month's interest is added to your principal, and the next month's interest is calculated on the larger amount. You receive the full amount at maturity. Use the compound interest formula with N = 12.
Non-cumulative FD. Interest still compounds monthly, but it is paid out at the frequency you choose. Your principal stays the same, because the interest leaves your deposit instead of being reinvested. Monthly compounding determines how much each payout is worth. A payout that covers 3 months* of interest is slightly higher than 3 equal slices of the annual simple-interest figure. On ₹1 Lakh* at 7%* p.a., a quarterly payout works out to about ₹1,760*, against ₹1,750* under simple interest.
That difference is small. But it is yours.

What are the Different Types of Fixed Deposits?
Not all FDs are the same. Understanding the different types helps you choose the one that actually fits what you're trying to do.
Cumulative FD
Interest compounds and is paid as a lump sum at maturity along with the principal. Better for long-term wealth building — the longer the tenure, the more compounding does its job. Best if you don't need income during the FD period.
Non-Cumulative FD
Interest is paid out at intervals you choose: monthly, quarterly, half-yearly, or yearly. The principal comes back at maturity. Better if you need a predictable income stream — particularly useful for retirees, homemakers, or anyone managing variable monthly cash flow.
Digital-Only FD
Some institutions — including Shriram Finance — offer specific schemes that are only available through online channels. The Shriram 15-month Digital FD is one such option.
FDs for Specific Investor Groups
Some institutions offer tailored rate benefits for specific investor categories:
- FDs for senior citizens — additional interest over the standard rate ({{FD_Senior}} with Shriram Finance) for those aged 60 and above
- FDs for women depositors — an additional {{FD_Women}} with Shriram Finance
- FDs for NRIs — can be booked only offline by visiting a physical Shriram Finance branch
What Determines Your FD Interest Rate?
Your FD rate isn't arbitrary. Several factors feed into it.
The RBI repo rate — When the Reserve Bank of India raises or cuts its repo rate, banks and NBFCs tend to follow, adjusting their deposit rates accordingly. RBI repo-rate cuts over recent years have shown that FD rates can shift rapidly in response to policy changes. If rates look likely to fall, locking in a longer tenure now makes sense.
The type of FD — Cumulative FDs often carry the same headline rate as non-cumulative ones, but the effective yield on cumulative is often higher because of compounding.
Tenure — Longer tenures generally come with higher rates. With Shriram Finance, a 12-month cumulative FD earns 7.00%* p.a., while a 36- to 60-month FD earns 7.85%* p.a. for general investors.
Your investor profile — Senior citizens, women depositors, and renewal customers all receive additional rate benefits ({{FD_Senior}}, {{FD_Women}}, and {{FD_Renewal}} respectively with Shriram Finance).
The institution's credit rating and regulatory standing — Institutions with higher credit ratings can attract deposits at competitive rates. An NBFC's rate reflects its funding needs, internal lending rates, and credit profile.
Shriram Finance is {{CRISIL_Ratings}} — the highest domestic credit rating across all four major agencies.
Bank FD vs NBFC FD — What's the Real Difference?
Both offer fixed deposits with locked-in rates. But there are meaningful differences worth understanding before you decide.
Interest rates vary across banks and NBFCs, and are subject to Reserve Bank of India regulation. A number of variables, such as the state of the market, the internal policies of the business, and its credit rating, affect interest rates.
The trade-off that most people cite is credit risk — bank deposits up to ₹5 lakh are insured by the Deposit Insurance and Credit Guarantee Corporation (DICGC), while NBFCs, like Shriram Finance, carry independent credit ratings from agencies like CARE, CRISIL, ICRA, and India Ratings that serve as a measure of their creditworthiness.
A few other practical differences:
Neither is universally better. Whether you’d benefit better from a bank FD or an NBFC FD depends on several factors, including your financial goals, returns preference and risk appetite.
FDs for Specific Groups of Investors
Let us now move on to understanding how specific groups of investors benefit from FDs.
FDs for Senior Citizens
If you're aged 60 or above, or investing on behalf of a parent who is, the additional {{FD_Senior}} benefit with Shriram Finance is one of the more tangible advantages available. With the effect of compounding into play, that half-percentage point adds meaningfully to the final maturity amount.
The non-cumulative option is particularly valuable here — monthly, quarterly, half-yearly or yearly payouts function as a supplement to pension income, helping retired investors manage regular expenses without touching the principal.
FDs for Women Depositors
Women investors earn an additional {{FD_Women}} over the standard rate with Shriram Finance. For a senior woman investor, both benefits apply simultaneously, bringing the maximum rate to {{FD}} This applies automatically to the account based on the depositor's profile — no separate application needed.

FDs for NRIs
With Shriram Finance specifically, fixed deposits for NRIs are accepted through NRO accounts on a non-repatriation basis, via offline mode only. Foreign nationals — except persons of Indian origin — are not accepted.
More broadly, NRIs have multiple FD options across financial institutions, each catering to different needs. NRO FDs are used to manage income generated in India, such as rent or dividends. NRE FDs allow income earned outside India to be deposited, with both principal and interest fully repatriable. FCNR FDs enable deposits in foreign currencies, helping avoid currency conversion risk.
How to Open a Shriram Fixed Deposit
The process for resident Indians is fully online:
- Visit in/fixed-deposit and register with your mobile number
- Enter your deposit amount, choose your tenure and payout preference
- Complete your KYC — PAN card, Aadhaar, and complete other declarations, and then make the payment
- Verify your bank account details
- Add nominee details
- Download your FD certificate
Please note that the generation of the FD certificate may take up to 7 days post payment.
You'll need your PAN card, Aadhaar card, and bank account details. The KYC process is completed digitally via a liveliness check. In this step, you take your picture and then the same picture is matched with the picture fetched from your Aadhaar.
NRI investors can only invest through the offline mode by visiting a Shriram Finance branch.
What Happens If You Need the Money Before Maturity?
Premature withdrawal is possible, but it comes with conditions and reduced returns.
For the first 3 months from the date of deposit or renewal with Shriram FD, your FD is locked in and generally cannot be withdrawn. Exceptions apply only for tiny deposits (up to ₹10,000, repaid in full with no interest), emergent situations like a medical emergency or a government-notified natural calamity (up to 50% of the principal or ₹5 lakh, whichever is lower, with no interest), critical illness (full repayment, with no interest), and the death of the depositor (full repayment, with no interest paid during the lock-in).
After 3 months, the terms work like this with Shriram FD:
- Between 3 and 6 months: you can withdraw the deposit, but you earn no interest at all.
- After 6 months but before maturity: you earn interest, but at a reduced rate — 2% lower than the rate applicable to a fixed deposit for the period actually held, or if no rate was specified for that period, 3% lower than the minimum rate at which fixed deposits are accepted.
For example, if a 5-year FD is prematurely closed after two years, the applicable premature-repayment rate is determined using the rate applicable for the period the FD has actually run, less 2%, subject to the applicable terms).
The practical takeaway: if there's any possibility you'll need the funds before maturity, either choose a shorter tenure or keep a separate emergency fund, so you're not forced to break the FD and lose out on interest.
FD Laddering — The Smarter Way to Invest
Putting all your money into one long-term FD at once is straightforward, but it carries a risk most people don't think about: what if interest rates rise after you've locked in?
FD laddering simply means dividing your total investment across multiple FDs with different maturity periods — instead of locking everything into one long-term deposit. For example, if you have ₹10 lakh, instead of a single FD, you create five FDs of ₹2 lakh each maturing in 1, 2, 3, 4, and 5 years. When the first FD matures after one year, you can either use the funds or reinvest them for another 5-year term at the prevailing interest rate.
The benefits compound over time:
Liquidity at regular intervals. One FD maturity per year means you're never too far from liquid funds without breaking anything early.
Rate exposure. If rates rise, your annually-maturing FDs get reinvested at higher rates. If rates fall, your long-tenure FDs are already locked in at the old, higher rate.
Goal alignment. You can match FD maturities to known financial goals — school fees, a home down payment, a parent's surgery. The money is available when you actually need it.
A practical example: instead of putting ₹5 lakh into a single 5-year FD with Shriram Finance, you split it into five deposits of ₹1 lakh each, maturing at 12, 24, 36, 48, and 60 months. Each year, one matures. You reinvest it into a fresh 5-year FD at the prevailing rate. Over time, all your money earns long-tenure rates while you maintain annual liquidity.
Common Mistakes to Avoid While Investing in an FD
Choosing tenure without thinking about when you actually need the money. This is the most frequent one. People lock in for 5 years because the rate is better, then face an expense in year 3 and break the FD — losing interest and paying a penalty.
Not adding a nominee. If you die without nominating someone, the institution requires legal heirs to go through a documentary process to claim the deposit. Adding a nominee takes two minutes and saves enormous difficulty later.
Ignoring the credit rating of an NBFC. Not all NBFCs are created equal. Before investing, check the credit rating — look for an AAA rating from recognised agencies (CARE, CRISIL, ICRA, India Ratings). This reflects the highest degree of creditworthiness.
Letting an FD auto-renew without checking the rate. At maturity, an FD can be auto-renewed for the same duration at the interest rate applicable at the time of renewal, which may be lower than what you originally earned. Check your maturity date, compare the applicable rate, and renew consciously rather than by default.
Breaking an FD impulsively when the market shifts. If interest rates rise, it can feel tempting to break your existing FD and rebook at the higher rate. But after factoring in the penalty, the calculation rarely works out in your favour.
