About RD Calculator
Guide1What is a Recurring Deposit (RD)?
A Recurring Deposit (RD) is a savings instrument offered by banks and post offices in India that allows you to invest a fixed amount every month for a predetermined tenure. It combines the discipline of regular saving with the safety and guaranteed returns of a fixed deposit.
RDs are ideal for individuals who want to save a fixed sum monthly and earn interest on their accumulated savings, without exposure to market risk.
2RD Interest Calculation
RD interest is compounded quarterly on each monthly deposit. The maturity value is:
M = R × [(1 + i)^n − 1] / [1 − (1 + i)^(−1/3)]
- R = monthly deposit
- i = quarterly rate = annual rate ÷ 400 (e.g. 7% → 0.0175)
- n = number of quarters = months ÷ 3
This is the same as compounding each monthly deposit quarterly for the months it stays invested and adding them up.

4RD vs SIP: Key Differences
- Returns: RD offers fixed guaranteed returns; SIP returns are market-linked and variable
- Risk: RD has near-zero risk; SIP carries market risk
- Potential: SIP can generate significantly higher returns over long periods
- Flexibility: Missing an RD installment attracts penalties; SIP can be paused freely
- Tax: RD interest is fully taxable; SIP equity gains have more favorable tax treatment
