A Recurring Deposit (RD) is a fixed deposit scheme offered by banks where you deposit a fixed amount at regular intervals (usually monthly) for a specified period. This calculator helps you determine the future value of your 15-year RD investment.
What is a Recurring Deposit (RD)?
A Recurring Deposit is a type of fixed deposit account where you agree to deposit a fixed amount periodically (usually monthly) for a specified term. The bank credits the amount to your account on the due date each month and pays interest on the monthly deposits.
RDs are popular among investors who want to build a corpus systematically over time. The interest is calculated on the monthly deposits, and the total amount grows with compound interest over the investment period.
Key Features of RD
- Fixed monthly deposits
- Fixed interest rate
- Lock-in period (typically 1-10 years)
- Premature withdrawal penalties
- Tax benefits under Section 80C of the Income Tax Act
How to Use This Calculator
Using our 15 Years RD Calculator is simple:
- Enter the monthly deposit amount in the first field
- Input the annual interest rate (in percentage)
- Click the "Calculate" button
- View your results including the total amount and interest earned
The calculator will show you the future value of your investment after 15 years, the total interest earned, and a growth chart.
Formula Used
The future value of a Recurring Deposit can be calculated using the following formula:
Recurring Deposit Formula
Future Value = P × [ ( (1 + r)^n - 1 ) / r ] × (1 + r)
Where:
- P = Monthly deposit amount
- r = Monthly interest rate (annual rate divided by 12)
- n = Total number of months (15 years × 12 = 180 months)
This formula accounts for the compounding of interest on each monthly deposit over the 15-year period.
Worked Example
Let's calculate the future value of a 15-year RD with:
- Monthly deposit: $1,000
- Annual interest rate: 7%
Calculation Steps
- Convert annual rate to monthly: 7% ÷ 12 ≈ 0.5833% or 0.005833 in decimal
- Number of months: 15 × 12 = 180
- Apply the formula:
Future Value = 1000 × [ ( (1 + 0.005833)^180 - 1 ) / 0.005833 ] × (1 + 0.005833)
- Calculate the components:
- (1 + 0.005833)^180 ≈ 3.25
- (3.25 - 1) / 0.005833 ≈ 219.5
- 219.5 × 1000 = 219,500
- 219,500 × 1.005833 ≈ 220,750
The future value of this RD investment would be approximately $220,750 after 15 years, with $20,750 in total interest earned.
Frequently Asked Questions
What is the difference between RD and FD?
A Fixed Deposit (FD) is a one-time deposit for a fixed period, while a Recurring Deposit (RD) involves regular monthly deposits. RDs are better for systematic savings and offer tax benefits under Section 80C.
Can I withdraw money from an RD before maturity?
Yes, but premature withdrawal may attract penalties. Some banks allow partial withdrawals after a certain period, while others may require the entire amount to be withdrawn.
Are RDs taxable?
The interest earned on RDs is taxable as per the individual's income tax slab. However, the principal amount is not taxed.
What is the minimum and maximum deposit amount for an RD?
Minimum deposit amounts typically range from ₹100 to ₹500, while maximum amounts can be up to ₹1.5 lakh or more, depending on the bank.
