RD Calculator

Recurring Deposit or RD is one of the most popular investment options in India that guarantees fixed returns. An RD account can be opened with any bank or post office by depositing a fixed amount regularly for a pre-defined tenure. The interest accumulates on the deposits to ultimately provide a lump sum maturity amount at the end of the tenure.

An RD calculator is an online tool which helps you calculate the maturity amount for an RD account, taking into account the deposit amount, tenure, and interest rate. In this guide, we'll discuss how to calculate RD interest.

What is RD?

Recurring Deposit is a fixed income instrument offered by banks and post offices in India. Some key features of RD accounts are:

• Fixed deposit amount - You must deposit a fixed predetermined amount at a defined frequency such as monthly, quarterly, etc.
• Fixed tenure - RD accounts come for a pre-defined period such as 1 year, 2 years, 3 years etc. There is no maximum duration.
• Fixed returns - The interest rate is fixed once you open the RD account. So, your returns are guaranteed.
• Flexible deposit option - You can deposit monthly, quarterly, half-yearly, or annually, depending on your preference. The total deposits in a year should meet the minimum amount criteria.
• Loan facility - Many banks offer loans against your RD accounts up to a certain limit.
• Tax benefits - RDs up to Rs. 1.5 lakhs qualify for tax benefit under Section 80C. The accumulated interest is taxable.

RD accounts are ideal for disciplined investors looking for guaranteed returns to meet short or medium term goals. The maturity corpus can be used to fund expenses for education, buying property, marriage, vacation, or other objectives.

How to Calculate RD Interest and Maturity Amount?

When you open an RD account, your investment grows in two ways:

1. Principal - Your monthly or periodic deposits towards the account

2. Interest - The interest rate offered by the bank accrues on principal and compounds annually

The maturity amount of the RD account is calculated using the following formula:

Maturity Amount = Total Principal + Interest on Principal

The total principal is easy to calculate - just multiply your periodic deposit by the total tenure in months or years.

Calculating the interest component is trickier. Here is the formula to calculate interest for RD:

Formula to Calculate RD interest

Interest = Monthly Deposit x {[(1+i)n - 1]/i} x i
Where,
i = Annual interest rate/12 (as interest is compounded monthly)
n = Tenure in months
Let's understand this better with the help of an example.

Say you have an RD account with the following details:
Monthly deposit - Rs. 5,000
Tenure - 5 years (60 months)
Interest rate - 7% p.a.
Here,
Monthly deposit (A) = Rs. 5,000
Total tenure in months (n) = 60
Annual interest rate (i') = 7%
Monthly interest rate (i) = 7/12 = 0.583%
Plugging this in the formula,
Interest = 5000 x {[(1+0.00583 )^60 - 1]/0.00583} x 0.00583 = Rs. 69,048
Total principal for 60 months = 60 x 5000 = Rs. 3,00,000

Therefore, maturity amount = Principal + Interest

= Rs. 3,00,000 + Rs. 69,048

= Rs. 3,69,048

So if you save Rs. 5,000 per month in an RD for 5 years at 7% interest, your maturity amount after 5 years will be Rs. 3,69,048.
Let's take one more example to understand the calculation better.
Suppose you have the following RD account:
Monthly deposit - Rs. 10,000
Tenure - 3 years (36 months)
Interest rate - 6.7% p.a.
Doing the math similarly:

Monthly deposit (A) = Rs. 10,000
Total tenure in months (n) = 36
Annual interest rate (i') = 6.7%
Monthly interest rate (i) = 6.7/12 = 0.558%
Plugging this in the formula,
Interest = 10000 x {[(1+0.00558)^36 - 1]/0.00558} x 0.00558
= Rs. 41,1432
Total principal for 36 months = 36 x 10000 = Rs. 3,60,000
Maturity amount = Rs. 3,60,000 + Rs. 41,432 = Rs. 4,01,432

So if you save Rs. 10,000 per month in an RD for 3 years at 6.7% interest, your maturity amount after 3 years will be Rs. 4,01,432.

This is how you can calculate the maturity amount for any RD account once you know the periodic deposit amount, tenure and interest rate.
