RD Maturity Formula
Formula (Quarterly Compounding):
M = R × [(1 + i)^n – 1] / [1 – (1 + i)^(–1/3)]
Where:
M = Maturity Value
R = Monthly Deposit
i = Quarterly Interest Rate (Annual Rate ÷ 4 ÷ 100)
n = Number of Quarters (Tenure in months ÷ 3)Worked Example
Scenario: ₹5,000/month RD for 2 years at 7% p.a.
RD Calculator — FAQs
RD interest is calculated using the formula: M = R × [(1 + i)^n – 1] / (1 – (1 + i)^(-1/3)), where R = Monthly deposit, i = Quarterly interest rate (annual rate ÷ 4 ÷ 100), n = Number of quarters. Most Indian banks compound RD interest quarterly.
