The RD calculator provided by SBI is designed to help users understand the maturity value of their recurring deposits. It calculates the total amount you will receive at the end of the deposit tenure based on your monthly contributions, the interest rate, and the duration of the RD. This tool is incredibly beneficial for planning and managing your savings, ensuring you can make informed decisions about your finances without delving into complex calculations.
Formula of RD Calculator in SBI
To grasp how the RD calculator works, it’s essential to understand the formula it uses:
A = P (1 + r/n) ^ nt
Where:
- A is the Maturity amount
- P is the Monthly deposit amount
- r is the Annual interest rate (converted to decimal)
- n is the Number of times interest is compounded in a year (usually quarterly, so n = 4)
- t is the Tenure of the RD in years
This formula calculates the future value of a series of equal payments (P) made at regular intervals, compounded at a specific interest rate (r).

Example of RD Calculator in SBI
Let’s consider a practical example to illustrate the use of the RD calculator:
If you decide to save ₹5,000 every month for a tenure of 5 years (t=5) in an RD with an annual interest rate of 6.5% (r=0.065), the maturity amount (A) would be calculated as follows:
A = 5000 (1 + 0.065/4)^(4*5)
This calculation shows the total amount you will receive at the end of the 5-year period, including the interest earned on your monthly deposits.
