RD Details

Recurring Deposit Facts

Quarterly Compounding

Bank RDs use quarterly compounding (4 times/year). Post Office RDs also use quarterly compounding. Both are covered by this calculator.

DICGC Insured

Bank RDs are insured up to ₹5 lakh per depositor per bank under DICGC. Post Office RDs are sovereign (government) guaranteed.

TDS on Interest

TDS @ 10% applies if interest > ₹40,000/year (₹50,000 for seniors). Submit Form 15G/15H if income is below taxable limit to avoid TDS.

Premature Closure

Banks allow premature closure at 1% penalty on applicable rate. Post Office RDs can be closed after 3 years (not before).

RD Calculator - Recurring Deposit Maturity

A Recurring Deposit (RD) is a term deposit product offered by banks and post offices that allows individuals to invest a fixed amount every month and earn guaranteed interest. RDs were introduced in India by post offices in the mid-20th century as a savings discipline tool for salaried and rural populations. Today, all scheduled commercial banks, cooperative banks, and India Post offer RDs, typically with tenures from 6 months to 10 years. As of 2024, SBI RD rates range from 6.5% to 7.0% per annum, while small finance banks offer up to 8.5%.

Quarterly Compounding Explained

RD interest in India is compounded quarterly, not monthly or annually, as per RBI guidelines. This means interest is calculated every three months on the outstanding balance and added back to the principal. The maturity formula is: M = R x [(1+i)^n - 1] / (1-(1+i)^(-1/3)), where R is monthly deposit, i is quarterly rate, and n is total quarters. Our calculator applies this exact formula so results match your bank's official figures within a few rupees.

Post Office RD vs Bank RD

Post Office RDs currently offer 6.7% per annum (Q1 FY25), backed by sovereign guarantee - making them ideal for risk-averse investors. Interest from RDs is fully taxable as per your income slab, and TDS at 10% applies if interest exceeds Rs 40,000 per year (Rs 50,000 for senior citizens).

RD Calculator Questions

A Recurring Deposit (RD) is a savings scheme where you deposit a fixed amount every month for a predetermined tenure. The bank pays compound interest (compounded quarterly) on accumulated deposits. At maturity, you receive total deposits plus interest - ideal for regular savers who want to save consistently and earn more than a savings account.

RD rates (2024-25): SBI 6.5–7.0%; HDFC Bank 6.6–7.25%; Post Office RD 6.7% (2 years), 7.0% (3 years), 7.4% (5 years). Senior citizens get 0.25–0.5% additional interest. Small finance banks offer 7.5–8.5%. Post Office RD carries a sovereign guarantee from the Government of India.

RD maturity uses quarterly compound interest: M = R × [(1+r/4)^(4n) – 1] ÷ [1 – (1+r/4)^(-1/3)], where R = monthly deposit, r = annual rate (decimal), n = tenure in years. Example: ₹5,000/month for 2 years at 7% → Maturity ≈ ₹1,29,200 (invested = ₹1,20,000, interest = ₹9,200). Our calculator handles all the math automatically.

Yes - RD interest is fully taxable as 'Income from Other Sources'. Banks deduct TDS at 10% if total interest from all RD/FD accounts exceeds ₹40,000/year (₹50,000 for senior citizens). Submit Form 15G or 15H to avoid TDS if your total income is below the taxable limit.

RD requires monthly deposits - suitable for regular savers without a lump sum. FD requires a single lump sum investment at the start and generally offers slightly higher rates than RD. Both are DICGC insured up to ₹5 lakh per bank. Post Office RD and FD carry a sovereign guarantee from the Government of India.
