A formula to determine RD maturity
The calculation of the RD maturity amount involves three key variables, which are processed by an RD account calculator using a standard recurring deposit formula to determine the precise maturity amount.
The formula for RD maturity is
A = P*(1+R/N)^(Nt)
Where:

A

P

N

Compounding frequency (number of quarters)

R

T

This formula serves as the universal method for calculating RD maturity amounts, irrespective of the invested amount or the investment duration. All that's required is to input the specific values.
For example, let us calculate the maturity amount of an RD considering the monthly deposit amount of Rs. 7,000 and an interest rate of 8.50%.
Using the above mentioned formula, here A will be the “Maturity Amount”, P will be “Monthly RD Instalment” (Rs. 7,000), N will be “Compounding Frequency” (number of quarters), R will be “RD Interest Rate” (8.50% or 0.085) and T will be “Tenure” (1 year, equivalent to 4 quarters).
Hence
A = P*(1+R/N)^(Nt)
= 7000*(1+0.085/4)^(4*12/12)
= Rs. 7,671.40
A = P*(1+R/N)^(Nt)
= 7000*(1+0.085/4)^(4*11/12)
= Rs. 7,521.88
A = = P*(1+R/N)^(Nt)
= 7000*(1+0.085/4)^(4*1/12)
= Rs. 7,049.37
For this specific investment scenario, summing up this series, the total maturity value, i.e., A, equals Rs 85,947.42.
