Introduction to Recurring Deposit Accounts
Unlock Audio Lesson
Today, we're learning about Recurring Deposit Accounts, or RDs. Can anyone tell me what they think this type of account is?
Is it a type of savings account where you save money?
Yes, exactly! RDs allow you to deposit a fixed amount every month for a set time. Why do you think this might be beneficial?
Maybe it helps people save money regularly?
Correct! It's a great way to save for a goal. Remember, RDs often come with interest too. We'll discuss how that works.
Calculating Interest
Unlock Audio Lesson
Now, let’s look at how to calculate the interest earned on your RD. The formula is I = P × n(n + 1) × r / (2 × 12 × 100). Who can tell me what each variable means?
P is the monthly deposit, n is the number of months, and r is the annual interest rate!
Well done! Here’s a mnemonic to remember the formula: 'Pi Never Rises.' Let’s try calculating the interest for a monthly deposit of ₹1,000 at an 8% annual interest rate for 12 months.
So, I would calculate it like this: 1000 × 12 × 13 × 8 / (2 × 12 × 100) = ₹520?
That's right! Great job!
Maturity Value of Recurring Deposits
Unlock Audio Lesson
Next, let’s figure out how to calculate the maturity value. The formula is MV = P × n + I. Can anyone break this down?
MV is the maturity value, P is the total deposits, n is the number of months, and I is the interest we just found!
Exactly! Now, what would be the maturity value if we used our earlier example with a monthly deposit of ₹1,000 and an interest of ₹520?
I think it would be ₹12,520!
Correct! Summarizing, the maturity value is simply your total deposits plus the interest.

Quick Overview
Standard
The section focuses on Recurring Deposit Accounts, detailing how they function, the formulas for calculating interest and maturity values, and providing practical examples to illustrate these concepts.
Detailed
The Banking section elaborates on Recurring Deposit Accounts (RDs), which are savings accounts where depositors contribute a fixed amount monthly for a predetermined period. Understanding RDs is essential as they help individuals save systematically. The section presents key formulas, including the interest formula, and how to calculate the maturity value of the account. Practical examples provide clarity on how to utilize these formulas in real-life scenarios.

● Recurring Deposit Account (RD): A savings account where a fixed sum is deposited every month for a fixed period.
Detailed Explanation
A Recurring Deposit (RD) account is a type of savings account which is designed for individuals who want to save money regularly. In this account, a person commits to depositing a fixed amount every month for a predetermined period—this could be six months, one year, or any duration up to several years. The advantage of an RD is that it encourages disciplined savings and helps individuals accumulate a sum of money for future needs. Additionally, RDs often offer better interest rates compared to regular savings accounts.
Examples & Analogies
Imagine you want to buy a bicycle that costs ₹12,000. If you decide to save ₹1,000 every month, in one year you will have saved ₹12,000, plus any interest earned. This means by consistently setting aside a fixed amount each month, you are more likely to reach your financial goal in a structured way.
Interest Calculation

● Interest (I) = P×n(n+1)×r2×12×100
Where:
○ P = Monthly deposit
○ n = Number of months
○ r = Annual rate of interest
Detailed Explanation
In a Recurring Deposit account, the interest earned is calculated using the formula provided. Here, 'P' represents the monthly deposit you make, 'n' is the total number of months for which you deposit this amount, and 'r' is the annual interest rate expressed as a percentage. The formula essentially allows you to compute how much interest you will accumulate over the period of the deposit. The term 'n(n+1)' is derived from the concept of simple interest, acknowledging that different deposits can earn interest for differing lengths of time depending on when they were deposited within the overall period.
Examples & Analogies
Think of it like watering plants. If you water them consistently (monthly deposits over the months), they grow (interest accumulates) depending on how much water (monthly deposit) and how well you care for them (interest rate). Just as some plants grow faster than others based on the care they receive, the interest rate affects the growth of your savings.
Maturity Value Calculation

● Maturity Value (MV) = P × n + I
Detailed Explanation
The maturity value is the total amount you receive at the end of the term of the Recurring Deposit. It is calculated by taking the total of all deposits made (P × n, where 'P' is the monthly deposit and 'n' is the number of months) and adding the interest earned during that period (I). This formula gives you a clear idea of the total wealth you will accumulate after completing the deposits and interest period.
Examples & Analogies
Consider a garden where you plant seeds (monthly deposits) and water them regularly (interest). After some time, you not only have your plants (total deposits) but also the fruits they bear (interest earned). Together, the plants and fruits represent what you have at the end—the maturity value.

Example
Monthly deposit = ₹1,000, n = 12 months, rate = 8% p.a.
Interest = 1000×12×13×82×12×100=₹520
Maturity Value = 1000 × 12 + 520 = ₹12,520
Detailed Explanation
In this example, a person decides to deposit ₹1,000 every month for a year with an interest rate of 8% per annum. The interest earned over 12 months is calculated using the provided formula. Therefore, the total interest is ₹520. The maturity value is calculated by summing up the total deposits (₹1,000 × 12) and the interest earned (₹520) resulting in a total of ₹12,520, showing all the money the individual will have at the end.
Examples & Analogies
Imagine setting up a savings plan for a holiday. By saving ₹1,000 every month for a year and earning interest as a bonus for your discipline, you would eventually have enough money not just for your holiday but also a little extra to spend on souvenirs or activities at the destination. This illustrates the benefit of consistent saving through an RD.
