What is a Recurring Deposit (RD) calculator?
An RD lets you deposit a fixed amount monthly for a chosen period at a guaranteed interest rate. Post Office RD offers 6.7% for 5 years. Bank RDs typically offer 6–8% depending on the bank and tenure. Interest is compounded quarterly.
Formula used
RD Maturity = R × [(1+i)^n − 1] / [1 − (1+i)^(−1/3)]
Where:
R = Monthly deposit
i = Quarterly rate = Annual rate ÷ 400
n = Number of quarters
Post Office RD rate: 6.7% p.a. (Q1 FY 2025-26)
