What is the RD Maturity Formula?
The Recurring Deposit (RD) maturity formula is a mathematical equation used to calculate the total amount you will receive at the end of your RD tenure. It takes into account your monthly investment, the annual interest rate, and the tenure of the deposit.
The formula ensures accurate calculations, helping you plan your savings and achieve your financial goals.
RD Maturity Formula
The standard formula to calculate the maturity amount of an RD is:
M = P × ((1 + r)^n - 1) / (1 - (1 + r)^(-1/n))
Where:
- M: Maturity Amount (the total amount you receive at the end of the tenure)
- P: Monthly Investment Amount
- r: Monthly Interest Rate (annual interest rate divided by 12)
- n: Total Tenure in Months
Step-by-Step Breakdown of the Formula
Let’s break down the formula into simple steps:
- Calculate the Monthly Interest Rate (r): Divide the annual interest rate by 12 to get the monthly rate. For example, if the annual interest rate is 7.5%, the monthly rate is 7.5 ÷ 12 = 0.625% or 0.00625.
- Determine the Total Tenure in Months (n): Convert the tenure from years to months if necessary. For example, 2 years = 24 months.
- Apply the Formula: Substitute the values of P, r, and n into the formula to calculate the maturity amount.
Example: If you invest ₹5,000 monthly at an annual interest rate of 7.5% for 2 years (24 months), the maturity amount is calculated as follows:
M = 5000 × ((1 + 0.00625)^24 - 1) / (1 - (1 + 0.00625)^(-1/24))
Result: ₹1,28,093.28 (Total Maturity Amount)

Common Questions About the RD Formula
Is the RD formula the same for all banks?
Yes, the standard RD formula is used by most banks in India. However, slight variations may occur due to differences in compounding methods or additional charges.
Can I calculate RD maturity manually?
Yes, you can calculate RD maturity manually using the formula. However, it’s recommended to use an online RD Calculator for faster and more accurate results.
How does compounding affect RD maturity?
RDs typically compound interest quarterly. This means the interest earned is added to the principal every quarter, leading to higher returns over time.
