What Is a Recurring Deposit?
A recurring deposit (RD) is a savings vehicle where you contribute a fixed amount each month and earn simple interest on those deposits over a set term. Banks typically compound interest quarterly, though the calculation treats each monthly deposit separately.
RDs occupy a middle ground between regular savings accounts and fixed deposits. Unlike a fixed deposit, which requires a lump sum upfront, an RD suits people who earn a salary and prefer to save in manageable monthly chunks. Interest rates on RDs closely match or sometimes exceed those on fixed deposits, making them attractive for disciplined savers.
Key features include:
- Fixed monthly contribution amounts
- Guaranteed interest rate locked in at account opening
- Terms typically ranging from 6 months to 10 years
- Interest earned on each deposit from the month it is made
- No penalty for completing the full term
How RD Interest Works
Interest on an RD is calculated using simple interest, not compound. Each monthly deposit earns interest from the day it is deposited until maturity. A deposit made in month 1 earns interest for the full term, while a deposit made in month 10 earns interest for fewer months.
The bank sums the interest earned on all deposits to arrive at your total interest. This weighted approach means early deposits generate more interest than later ones—an incentive to maintain consistent contributions throughout the term.
For example, if you deposit ₹5,000 monthly for 24 months at 7% annual interest, your first deposit works harder over time than your final deposit. The formula accounts for this by factoring in the number of months remaining for each contribution.
RD Maturity Calculation
To find your maturity amount, calculate total deposits and accrued interest, then sum them:
Total Deposits = Monthly Deposit × Number of Months
Interest = (Monthly Deposit × Months × (Months + 1) × Annual Rate) ÷ 2400
Maturity Amount = Total Deposits + Interest
Monthly Deposit— Fixed amount deposited each monthNumber of Months— RD tenure converted to months (e.g., 5 years = 60 months)Annual Rate— Interest rate per annum as a percentageMaturity Amount— Total value at end of RD term, including principal and interest
Worked Example
Suppose you invest ₹2,500 monthly for 3 years (36 months) at an 8% annual interest rate.
Step 1: Total deposits
₹2,500 × 36 = ₹90,000
Step 2: Interest earned
Interest = (₹2,500 × 36 × 37 × 8) ÷ 2400 = ₹11,100
Step 3: Maturity amount
₹90,000 + ₹11,100 = ₹101,100
After 3 years, your ₹90,000 in deposits grows to ₹101,100, thanks to ₹11,100 in interest earnings.
Key Considerations for RD Investors
Avoid common pitfalls and maximise your RD returns with these practical insights.
- Rate Lock-In Risk — Interest rates are fixed when you open the account. If market rates rise significantly, your RD will earn the original lower rate until maturity. Conversely, if rates fall, you benefit from the locked-in rate. Consider your market expectations before committing to a longer term.
- Early Withdrawal Penalties — Withdrawing before maturity typically incurs a penalty—often 0.5% to 1% of interest earned or a small reduction in your rate. Plan your RD term conservatively, ensuring you won't need the funds urgently.
- Inflation Erodes Real Returns — Your RD earns a nominal rate, but inflation erodes purchasing power. A 6% RD earning ₹15,000 interest might lose real value if inflation runs 4-5%. Use RDs as part of a diversified savings mix, not your sole investment.
- Tax on Interest Income — Interest earned on RDs is fully taxable as income in the year it matures. If you expect a high income year, consider spreading RD maturity dates across multiple years to avoid a sudden tax spike.
