What Is a Recurring Deposit?

A Recurring Deposit (RD) is a fixed-income investment product offered by banks and post offices where you invest a fixed amount every month and earn interest compounded quarterly. It is designed for individuals who want to build a savings corpus through regular monthly instalments.

Unlike a Fixed Deposit where you invest a lump sum at once, an RD allows you to contribute modest amounts monthly, making it ideal for salaried individuals and anyone looking to build a saving habit. The minimum monthly deposit at the Post Office is just Rs 100, and most banks accept as little as Rs 500 per month.

RDs are governed by RBI guidelines and offer guaranteed returns irrespective of market movements. The interest rate is fixed at the time of opening the account and remains constant for the entire tenure, making RD one of the safest investment options available in India. Per RBI data, scheduled commercial banks held over Rs 3.5 lakh crore in RD deposits as of March 2025.

RD Formula and Calculation Method

The standard formula for calculating RD maturity in Indian banking uses quarterly compounding. Each monthly deposit earns interest independently from the month it is deposited until the end of the tenure.

M = P x (1 + R/400)^(4 x t1) + P x (1 + R/400)^(4 x t2) + ... + P x (1 + R/400)^(4 x tn)
VariableMeaning
MTotal maturity amount
PMonthly deposit amount
RAnnual interest rate (in %)
tTime in years for each deposit

Worked example: You deposit Rs 5,000 every month for 3 years at an 8% quarterly-compounded rate. The first deposit earns interest for 36 months (3 years), the second for 35 months, and so on. The maturity value is the sum of each deposit with its compounded interest. This calculator performs that series automatically.

RD vs FD: Key Differences

The primary difference between RD and FD is the investment pattern. An FD requires a one-time lump sum deposit, while an RD accepts monthly instalments. Both offer fixed, guaranteed returns and are among the safest fixed-income instruments in India.

Best forMonthly saversLump sum investors

For salaried individuals with no large lump sum, an RD is the more practical instrument. For those with a significant amount ready to invest, FDs generally offer a slightly higher rate. Many banks offer 0.25% to 0.50% higher rates on FDs compared to RDs for the same tenure. Compare both using Fermor's FD Calculator.

Quarterly Compounding in RD Explained

Quarterly compounding means the interest is calculated and added to the principal once every three months. In RD, this is the standard method prescribed by the Indian Banks Association. The compounding frequency of 4 times per year (N=4) means each monthly deposit earns compound interest that grows faster than simple interest but slower than monthly compounding.

Compounding FrequencyFormula (for 1 year at 8%)Effective Annual Rate
Yearly (N=1)(1 + 0.08/1)^1 - 18.000%
Half-yearly (N=2)(1 + 0.08/2)^2 - 18.160%
Quarterly (N=4)(1 + 0.08/4)^4 - 18.243%
Monthly (N=12)(1 + 0.08/12)^12 - 18.300%

The effective annual rate increases with compounding frequency. Quarterly compounding, which all Indian banks use for RDs, gives an effective rate of 8.243% when the nominal rate is 8%. Over long tenures, this difference compounds significantly. A monthly deposit of Rs 5,000 at 8% for 10 years earns approximately Rs 1,08,000 more than the simple interest equivalent.

RD Taxation: How RD Returns Are Taxed

RD interest is fully taxable as per your income tax slab. Unlike PPF or EPF, RD does not enjoy EEE (Exempt-Exempt-Exempt) status. The interest earned is added to your total income and taxed at your applicable slab rate. No tax deduction under Section 80C is available on the principal amount invested in an RD.

TDS on RD Interest

Banks deduct TDS at 10% if the total interest from all deposits with that bank exceeds Rs 40,000 in a financial year. For senior citizens, the threshold is Rs 50,000. If you have not submitted your PAN to the bank, the TDS rate becomes 20%. The TDS is reflected in your Form 26AS and can be claimed as credit while filing your income tax return.

Tax Planning Tip

If your total income is below the taxable threshold, submit Form 15G (or Form 15H for senior citizens) to the bank at the start of the financial year to avoid TDS deduction. The interest will still be taxable, but you can avoid the upfront deduction and pay any applicable tax at the time of filing. For tax-efficient fixed-income investing, PPF offers EEE status under Section 80C. Use the PPF Calculator to compare.

Current RD Interest Rates in India

RD interest rates are reviewed and updated periodically by banks and the Post Office. These rates are typically 0.25% to 0.50% lower than the corresponding FD rates for the same tenure. Below are indicative rates across major institutions as of mid-2026.

Indicative RD rates across major Indian institutions
InstitutionRate (p.a)Tenure Range
Post Office RD6.7%5 years
State Bank of India5.5 to 7.0%1 to 10 years
ICICI Bank5.5 to 7.25%6 months to 10 years
HDFC Bank5.5 to 7.25%6 months to 10 years
Axis Bank5.5 to 7.5%6 months to 10 years
Yes Bank6.0 to 7.75%1 to 10 years
AU Small Finance Bank7.0 to 9.0%1 to 10 years
Equitas Small Finance Bank7.0 to 8.5%1 to 10 years

Senior citizens typically receive 0.50% to 0.75% higher rates on RDs, similar to FDs. Small finance banks offer higher rates because they need to attract deposits to meet priority sector lending norms under RBI regulations. Per RBI data, small finance banks held approximately Rs 25,000 crore in RD deposits as of Q4 FY25.

Limitations of Recurring Deposits

Lower returns than market-linked productsEquity mutual funds historically deliver 12 to 15% CAGR over long periods, while RD rates are in the 5.5 to 7.5% range. For long-term wealth creation, RDs underperform equities significantly after adjusting for inflation.
No tax benefits under Section 80CUnlike PPF, ELSS, and life insurance premiums, the amount invested in RD does not qualify for tax deduction under Section 80C of the Income Tax Act. Only the interest is taxed, which is an additional disadvantage.
Interest rate locked inWhen you open an RD, the rate is fixed for the full tenure. If market rates rise, you cannot benefit. Conversely, if rates fall, your RD continues at the higher rate. Some banks offer floating-rate RDs, but the standard product is fixed.
TDS on interestRD interest exceeding Rs 40,000 (Rs 50,000 for senior citizens) attracts TDS at 10%. For investors in higher tax brackets, the post-tax return can be significantly lower than the headline rate.
