How Recurring Deposits Work
A Recurring Deposit (RD) is a fixed-amount monthly savings scheme offered by banks and post offices in India that pays quarterly-compounded interest at maturity. Unlike a Fixed Deposit (FD), which requires a lump-sum investment up front, an RD lets you deposit a fixed amount every month for a predetermined tenure, typically ranging from 6 months to 10 years. At the end of the tenure, you receive the maturity value, which consists of your total deposits plus the interest earned.
The key feature that makes RDs attractive is quarterly compounding. Instead of earning simple interest, the bank compounds your interest every three months. This means you earn interest on previously earned interest every quarter, which accelerates the growth of your savings over time. Each monthly instalment is treated as a separate mini-deposit that earns compound interest for the remaining duration of the RD.
RDs are particularly popular among salaried individuals in India because they enforce a disciplined savings habit. The monthly deposit amount is fixed at the time of opening the account and cannot be changed during the tenure. Most banks offer RDs with minimum deposits as low as ₹100 per month (₹10 for post office RDs), making them accessible to virtually everyone. RD interest rates, published periodically by individual banks under RBI guidelines, typically range from 5.5% to 7.5% per annum depending on the bank, tenure, and whether the depositor is a senior citizen (who usually get 0.25% to 0.50% extra).
RDs are covered under the Deposit Insurance and Credit Guarantee Corporation (DICGC), which insures deposits up to ₹5,00,000 per depositor per bank. This makes RDs one of the safest savings instruments available. However, the interest earned is fully taxable, and banks deduct TDS per Income Tax Act provisions if the interest exceeds the threshold limit.
RD Formula
The maturity value of an RD is calculated by treating each monthly instalment as a separate deposit that earns quarterly compounded interest for the remaining tenure. The formula for the maturity amount from each instalment is:
A = P x (1 + r/4)(remaining months / 3)
Where P is the monthly deposit, r is the annual interest rate as a decimal, and remaining months / 3 converts the remaining tenure into quarters. The total maturity value is the sum of each instalment's accumulated amount.
Worked example: You open an RD with ₹5,000 per month at 7% annual interest for 12 months.
- Quarterly rate = 7% / 4 = 1.75%
- Month 1 deposit earns interest for 11 remaining months = 11/3 = 3.667 quarters
- Month 1 amount = ₹5,000 x (1.0175)3.667 = ₹5,000 x 1.0656 = ₹5,328
- Month 6 deposit earns interest for 6 remaining months = 2 quarters
- Month 6 amount = ₹5,000 x (1.0175)2 = ₹5,000 x 1.0353 = ₹5,177
- Month 12 deposit earns interest for 0 remaining months = 0 quarters
- Month 12 amount = ₹5,000 x (1.0175)0 = ₹5,000
- Total deposited: ₹60,000 | Maturity value: approximately ₹62,300 | Interest earned: approximately ₹2,300
This calculator performs this computation for every instalment automatically, giving you an accurate estimate of your maturity value. Actual bank figures may vary slightly due to rounding conventions and the specific day-count methods used by each institution.
Key Terms
| Term | Definition |
|---|---|
| Recurring Deposit (RD) | A term deposit where you invest a fixed amount every month for a predetermined period. Available at all scheduled banks and post offices in India. |
| Maturity Value | The total amount you receive at the end of the RD tenure. It equals total deposits plus compound interest earned. |
| Quarterly Compounding | Interest is calculated and added to the principal every three months. This means you earn interest on previously earned interest four times a year, resulting in higher effective returns than simple interest. |
| TDS (Tax Deducted at Source) | Banks deduct TDS at 10% on RD interest if total interest across all deposits exceeds ₹40,000 per year (₹50,000 for senior citizens). Submit Form 15G/15H to avoid TDS if your total income is below the taxable limit. |
| Premature Withdrawal | Closing the RD before the maturity date. Most banks apply a penalty of 0.5% to 1% reduction on the applicable interest rate. Post office RDs can be closed prematurely after completing 3 years. |
RD vs FD vs SIP Comparison
Choosing between a Recurring Deposit, Fixed Deposit, and Systematic Investment Plan depends on your goals, risk appetite, and cash flow. The table below highlights the key differences:
| Feature | RD | FD | SIP (Mutual Fund) |
|---|---|---|---|
| Investment Type | Monthly fixed amount | One-time lump sum | Monthly (flexible amount) |
| Returns | Fixed (5.5%-7.5% p.a.) | Fixed (6%-7.5% p.a.) | Market-linked (10%-15% p.a. historical avg for equity) |
| Risk | Very low (DICGC insured) | Very low (DICGC insured) | Low to high (depends on fund type) |
| Liquidity | Low (penalty on early withdrawal) | Low (penalty on early withdrawal) | High (redeem anytime for open-ended funds) |
| Taxation | Interest fully taxable + TDS | Interest fully taxable + TDS | LTCG above ₹1.25L taxed at 12.5% (equity); debt funds taxed per slab |
| Best For | Conservative savers, short-term goals | Lump-sum parking, fixed returns | Long-term wealth creation, inflation-beating returns |
For conservative savers with short-term goals (1-3 years), RDs offer guaranteed returns with zero market risk. For long-term wealth creation (5+ years), SIPs in equity mutual funds historically outperform RDs significantly. Use our SIP calculator to compare potential returns from mutual fund SIPs.
Practical Examples
The following table shows how different monthly deposits grow over various tenures at common interest rates. All figures assume quarterly compounding.
| Monthly Deposit | Rate | Tenure | Total Deposited | Interest Earned | Maturity Value |
|---|---|---|---|---|---|
| ₹5,000 | 6.5% | 1 year | ₹60,000 | ~₹2,100 | ~₹62,100 |
| ₹5,000 | 7.0% | 3 years | ₹1,80,000 | ~₹20,200 | ~₹2,00,200 |
| ₹5,000 | 7.0% | 5 years | ₹3,00,000 | ~₹58,700 | ~₹3,58,700 |
| ₹10,000 | 7.0% | 5 years | ₹6,00,000 | ~₹1,17,400 | ~₹7,17,400 |
| ₹5,000 | 7.5% | 5 years | ₹3,00,000 | ~₹63,500 | ~₹3,63,500 |
As the table shows, both tenure and interest rate have a significant impact on your earnings. A ₹5,000/month RD at 7% for 5 years earns approximately ₹58,700 in interest, but increasing the rate by just 0.5% to 7.5% boosts the interest to approximately ₹63,500 -- an extra ₹4,800 for the same effort. Similarly, extending the tenure amplifies compounding significantly.
Tips for Maximizing RD Returns
- Compare rates across banks: Interest rates can vary by 0.5% to 1% between banks. Small finance banks and some co-operative banks often offer higher RD rates than large nationalized banks. Check current rates before opening an RD.
- Choose longer tenures when rates are high: If current interest rates are favorable, lock in a longer tenure (3-5 years) to benefit from the higher rate for the entire period. RD rates are fixed at the time of account opening.
- Leverage senior citizen benefits: Senior citizens (60+) typically get 0.25% to 0.50% higher interest rates. If you are a senior citizen or are opening an RD for a senior family member, always ask for the senior citizen rate.
- Avoid premature withdrawal: Breaking an RD early not only incurs a penalty but also results in a lower effective interest rate. Plan your RD tenure to match your financial goal so you do not need to withdraw prematurely.
- Submit Form 15G/15H to avoid TDS: If your total annual income is below the basic exemption limit, submit Form 15G (or 15H for seniors) to your bank to prevent TDS deduction on your RD interest. This ensures your full interest amount stays invested.
- Consider a ladder strategy: Instead of one large RD, open multiple RDs with staggered maturities (e.g., 1 year, 2 years, 3 years). This provides periodic liquidity while still earning compound interest. As each RD matures, reinvest into a new longer-tenure RD.
- Automate deposits: Set up a standing instruction or auto-debit from your salary account on the day after your salary credit. This removes the risk of missing an instalment and incurring penalties.

Frequently Asked Questions
What is a Recurring Deposit (RD)?
A Recurring Deposit (RD) is a term deposit scheme offered by banks and post offices in India where you deposit a fixed amount every month for a predetermined tenure. Interest is compounded quarterly, and you receive the maturity value (total deposits plus interest) at the end of the tenure. RDs are ideal for salaried individuals who want to build savings gradually without needing a large lump sum. Minimum deposits start from ₹100/month at most banks and ₹10/month at post offices.
How is RD interest calculated?
RD interest is calculated using quarterly compounding. Each monthly instalment is treated as a separate deposit that earns compound interest for the remaining months of the tenure. The formula applied to each instalment is P x (1 + r/4)^(remaining months / 3), where P is the monthly deposit and r is the annual interest rate. The bank sums up the accumulated value of all instalments to determine the maturity amount. This method ensures earlier deposits earn more interest than later ones.
Is RD interest taxable in India?
Yes, RD interest is fully taxable in India under the head "Income from Other Sources." It is added to your total income and taxed at your applicable income tax slab rate. If the total interest earned across all RDs and FDs in a bank exceeds ₹40,000 in a financial year (₹50,000 for senior citizens), the bank deducts TDS at 10%. You can submit Form 15G (or Form 15H for senior citizens) if your total income is below the taxable limit to prevent TDS deduction.
Can I withdraw my RD before maturity?
Yes, most banks allow premature withdrawal of an RD, but a penalty is usually charged. The penalty is typically a 0.5% to 1% reduction in the applicable interest rate for the actual period the RD was held. Some banks do not allow partial withdrawal and require you to close the entire account. Post office RDs can be prematurely closed after completing 3 years of the tenure. It is advisable to check your bank's specific terms before opening an RD.
What is the difference between RD and FD?
A Fixed Deposit (FD) requires a one-time lump-sum investment at the start, while a Recurring Deposit (RD) allows you to invest a fixed amount monthly over the tenure. FDs generally offer slightly higher interest rates (0.1% to 0.25% more) than RDs of the same tenure because the entire principal earns interest from day one. FDs are better when you have surplus cash to invest, while RDs are designed for people who want to save regularly from their monthly income. Both offer similar safety as they are covered under DICGC insurance up to ₹5 lakh per depositor per bank.
What happens if I miss an RD instalment?
If you miss an RD instalment, most banks charge a small penalty, typically ₹1 to ₹2 per ₹100 of the instalment amount for each month of delay. You are expected to pay the overdue instalment along with the penalty in the next month. If you miss too many consecutive instalments (usually 3 to 6 months depending on the bank), the bank may prematurely close your RD account and pay interest at the rate applicable for the period actually completed, which is usually lower than the original contracted rate.
