Complete Guide to Bank Fixed Deposits (FD) & Recurring Deposits (RD) in India
Fixed Deposits (FDs) and Recurring Deposits (RDs) represent the bedrock of conservative savings for millions of Indian households. Governed by Reserve Bank of India (RBI) prudential guidelines and offered by Scheduled Commercial Banks, Small Finance Banks, and India Post (Post Office Time Deposits), these instruments provide guaranteed capital safety and fixed, predictable interest payouts.
1. Mathematical Formulations for FD and RD Maturity Calculations
Indian commercial banks calculate Fixed Deposit returns using quarterly compounding:
Where P is the principal deposit, r is the annual interest rate, n is the compounding frequency per year (n = 4 for quarterly), and t is tenure in years.
Where P is the fixed monthly deposit instalment and i is the monthly periodic interest rate.
2. FD vs RD: Choosing the Right Instrument
- Fixed Deposit (FD): Best suited when you possess a lump sum amount (e.g. annual bonus, property sale proceeds, retirement gratuity) that you want to lock away for a guaranteed return over a fixed horizon.
- Recurring Deposit (RD): Ideal for salaried professionals who wish to build a disciplined emergency fund by setting aside a fixed portion of their monthly paycheck without equity market risks.
Frequently Asked Questions on FD & RD
Yes. All Scheduled Small Finance Banks (such as AU Small Finance Bank, Equitas, Ujjivan) are regulated by the RBI and carry the exact same DICGC deposit insurance protection of up to ₹5,00,000 per depositor (covering both principal and interest) as State Bank of India, HDFC Bank, or ICICI Bank.
Banks typically levy a premature penalty of 0.50% to 1.00% on the applicable interest rate for the actual period the deposit remained with the bank, rather than the contracted rate. Tax-saving 5-year FDs cannot be prematurely withdrawn under any circumstances.
You can submit Form 15G (for individuals aged below 60) or Form 15H (for senior citizens aged 60+) to your bank at the beginning of each financial year (in April). Submitting this self-declaration certifies that your estimated total income for the financial year is below the basic tax exemption limit, prompting the bank to pay full interest without any TDS deduction.
