Frequently Asked Questions

A Fixed Deposit (FD) is a financial instrument offered by banks where you deposit a lump sum for a fixed tenure at a predetermined interest rate. The interest is compounded at regular intervals and paid at maturity. FDs are considered one of the safest investment options as they are not affected by market fluctuations.
FD interest is calculated using compound interest: A = P × (1 + r/n)nt where P = Principal, r = Annual rate (decimal), n = Compounding frequency per year, t = Time in years. Most banks compound FD interest quarterly (n=4). Total interest = A − P.
Most Indian banks compound FD interest quarterly. Some banks may compound monthly or annually. You can select the compounding frequency using the tabs above to match your bank's terms. Quarterly compounding is the most common.
Yes. FD interest is fully taxable as "Income from Other Sources" in India. TDS at 10% is deducted if interest exceeds ₹40,000 per year (₹50,000 for senior citizens). If your income is below the taxable limit, submit Form 15G/15H to avoid TDS deduction.
In a Cumulative FD, interest is compounded and paid at maturity with the principal — this calculator models cumulative FD, ideal for wealth accumulation. In a Non-Cumulative FD, interest is paid out periodically (monthly, quarterly, or annually), reducing the compounding benefit. Non-cumulative FDs are preferred for regular income needs.
Yes, most FDs allow premature withdrawal, but banks typically charge a penalty of 0.5–1% on the applicable interest rate. The actual interest earned will be lower than the projected amount in this calculator. Always check your bank's premature withdrawal policy before investing.
The EAR accounts for compounding within the year: EAR = (1 + r/n)n − 1. For example, a 7% FD compounded quarterly has an EAR of approximately 7.19%. The EAR lets you compare FDs with different compounding frequencies on equal terms.
Tips: (1) Choose higher compounding frequency (monthly > quarterly > annually). (2) Use FD laddering — split across multiple FDs with different tenures. (3) Look for small finance banks that offer higher rates. (4) Reinvest matured FDs immediately. (5) Senior citizens typically get 0.25–0.50% extra interest.
FDs generally offer higher interest rates than savings accounts — typically 1–4% more per year. However, savings accounts offer full liquidity, while FDs lock funds for a fixed tenure with penalties for early exit. For money you won't need for 6+ months, an FD is almost always the better choice.
Banks pay interest at the rate applicable for the actual holding period minus a penalty of 0.5–1%. For example, if your FD was booked at 7% for 3 years but you break it after 1 year, you'd earn approximately 5–5.5% for that year. To avoid this, consider laddering FDs across short, medium, and long tenures.

Senior Citizen FD Premiums, Tax-Saver Trade-Offs, and NRE vs NRO — How to Choose the Right Fixed Deposit
The 0.25-0.50% senior citizen FD premium isn't charity — it reflects banks competing for a high-balance, high-retention depositor segment. Here's why the Section 80C tax-saver FD sometimes loses to a regular FD at a higher rate once you account for the 5-year lock-in, how to correctly compare "special tenure" FDs at unusual maturities, and why NRE FDs have been particularly attractive for NRIs when Indian rates exceed foreign deposit rates.

Why Two FDs With the Same Interest Rate Can Pay Different Returns — Compounding Frequency, AER, and After-Tax Reality
A 5% FD compounded monthly earns an effective 5.116% annually — more than a 5% FD compounded only at maturity. Here's the AER (Annual Equivalent Rate) standard that allows fair comparison regardless of compounding frequency, the cumulative vs non-cumulative FD distinction, why after-tax rates (not headline rates) are what to compare when choosing between FDs and ISAs, and early withdrawal penalties as the hidden cost of the illiquidity premium.

Real vs Nominal FD Returns: Why a "Guaranteed 5%" Deposit Can Quietly Lose You Purchasing Power
A fixed deposit "guaranteeing" 5% can still leave you with less purchasing power than you started with — if inflation runs at 6%, the real return is approximately -1%, and after accounting for tax on the interest, the gap widens further. Here's the nominal-vs-real return relationship, why "nominally safe" doesn't mean "really safe," and how this gap becomes far more consequential during high-inflation periods than during the low-inflation periods many savers are used to.
