A **Recurring Deposit (RD)** is an extremely popular investment tool offered by post offices and commercial banks throughout India. Unlike a Fixed Deposit, where you need to invest a large sum of money all at once, an RD allows you to deposit a fixed, affordable amount of money **every calendar month** for a chosen term.
RD accounts encourage self-discipline by mandating a monthly installment payout. FDs and RDs share identical interest rate offerings, tax brackets, and senior citizen premiums. It offers the exact safety of term deposits since the interest rate remains locked in when the account is opened.
Standard commercial banks compound RD interest **quarterly** (every 3 months). The mathematical formula utilized to calculate the final maturity amount ($M$) of an RD is:
$$M = P \times \frac{(1 + i)^n - 1}{1 - (1 + i)^{-1/3}}$$
Where:
• $M$ = Final Maturity Value of the Recurring Deposit.
• $P$ = Monthly Installment Amount.
• $i$ = Quarterly interest rate, derived as $\frac{R}{400}$ where $R$ is the nominal interest rate p.a.
• $n$ = Number of compounding quarters. For a term of $T$ months, $n = \frac{T}{3}$ quarters.
This formula reflects that your first monthly installment earns interest for the full term, while subsequent monthly contributions compound for progressively shorter time spans.
• **Tenure and Thresholds**: Standard bank RD tenures range from **6 months to 10 years** in multiples of 3 months. Monthly contributions can start from as low as ₹100.
• **TDS (Tax Deducted at Source)**: Interest earned from Recurring Deposits is fully taxable based on your tax slabs. Similar to FDs, banks will deduct TDS at 10% if the combined interest earned on all term deposits in the fiscal year exceeds ₹40,000 (₹50,000 for senior citizens).
• **Default Penalties**: If you miss your monthly RD installment payment, banks will charge a small penalty (normally ₹1 or ₹2 per ₹100 installment per month) and can suspend your account if deposits remain unpaid for several months.
