The interest earned on an RD is calculated using the compound interest formula. The formula is:
The formula for RD maturity is: A = P*(1+R/N)^(Nt)
Where:
| Variable | Meaning |
| A | Maturity amount |
| P | Monthly RD instalment |
| N | Compounding frequency (number of quarters) |
| R | RD Interest rate (as a percentage) |
| T | Tenure |
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.

Premature withdrawal of RD
Premature withdrawal is allowed but may attract a penalty. The penalty amount varies across banks and usually involves a reduction in the applicable interest rate.
Partial withdrawal of RD
Some banks allow partial withdrawal of RD funds to meet urgent financial needs. However, this facility may come with restrictions on the amount and frequency of withdrawals.
Tax exemptions of an RD
The interest earned on RDs is taxable under the Income Tax Act. TDS (Tax Deducted at Source) is applicable if the interest exceeds Rs. 40,000 in a financial year (Rs. 50,000 for senior citizens).
