What Is A Recurring Deposit (RD)?
A Recurring Deposit (RD) is a savings scheme where an investor deposits a fixed amount every month for a predetermined period at a fixed interest rate. At maturity, the investor receives the total invested amount plus interest.

Key Features of Recurring Deposit
- Fixed monthly investment
- Fixed tenure (usually 6 months to 10 years)
- Guaranteed returns
- Compound interest
- Suitable for salaried individuals and small savers
RDs are offered by banks, post offices, and NBFCs, making them easily accessible and safe.
Types of Recurring Deposits
Bank Recurring Deposit
- Offered by public and private banks
- Flexible tenure options
- Auto-debit facility available
Post Office Recurring Deposit
- Government-backed
- Fixed 5-year tenure
- Lower risk and stable returns
The Recurring Deposit Calculator can be used for both bank and post office RDs.
Taxation on Recurring Deposit
Understanding tax is important when estimating RD returns.
- Interest earned on RD is fully taxable
- Taxed as per the investor’s income tax slab
- TDS may apply if interest crosses the prescribed limit
Most RD calculators show pre-tax returns, so investors should calculate post-tax income separately.
Premature Withdrawal and Penalty
- RD allows premature closure after a minimum period
- Penalty varies by bank or post office
- Interest may be reduced on early withdrawal
The calculator assumes the RD runs till maturity.
What is a Recurring Deposit Calculator?
A Recurring Deposit Calculator is an online tool that calculates:
- Total investment amount
- Interest earned during the tenure
- Maturity amount at the end of the RD period
By entering basic details like monthly deposit, interest rate, and tenure, the calculator instantly displays accurate results—without the need for manual calculations.
How Does a Recurring Deposit Calculator Work?
The RD Calculator works on the principle of compound interest, where each monthly deposit earns interest for a different duration depending on when it is deposited.
To use a Recurring Deposit Calculator, you need to provide:
- Monthly deposit amount
- Interest rate (annual)
- Investment tenure (in months or years)
Once entered, the calculator applies the RD interest formula and displays the maturity amount.
RD Formula
Each monthly installment compounds separately:
M = P × [ (1 + r/n)^(nt) − 1 ] / [1 − (1 + r/n)^(-1/n)]
Where:
M= Maturity amountP= Monthly depositr= Annual interest raten= Compounding frequencyt= Tenure in years
The Recurring Deposit Calculator handles this complexity automatically.
Example Using Recurring Deposit Calculator
Let’s consider an example:
- Monthly Deposit: ₹2,000
- Interest Rate: 6.5% per annum
- Tenure: 5 years
Total investment = ₹2,000 × 60 = ₹1,20,000
Using a Recurring Deposit Calculator, you can instantly see:
- Total interest earned
- Final maturity amount
This helps you decide whether the RD meets your savings goal.
Benefits Of The RD Calculator
- Accurately calculates maturity amount and total interest earned
- Helps plan monthly savings according to financial goals
- Saves time by eliminating manual calculations
- Allows comparison of different deposit amounts and tenures
