Good to know
Banks and the Post Office compound RD interest every quarter. Each instalment earns interest for the months it stays in the account, so the first instalment earns the most and the last one the least. The calculator adds up every instalment this way, which equals the formula banks publish.
The Post Office 5-year RD pays 6.7% for Oct–Dec 2026, reviewed every quarter; the rate on your account opening date applies for the full term. ₹10,000 a month for 5 years at 6.7% matures at about ₹7.14 lakh.
RD interest is taxable like FD interest and banks deduct TDS above the yearly limit. Missing an instalment usually attracts a small penalty, and several missed instalments can lead to closure.
Questions
How is RD maturity calculated?
M = R × [(1 + i)^n − 1] ÷ [1 − (1 + i)^(−1/3)], with R the instalment, i the quarterly rate (rate ÷ 400) and n the number of quarters.
What is the Post Office RD rate now?
6.7% a year for October–December 2026, for the 5-year RD. Check India Post for the current quarter.
RD or SIP?
An RD gives a fixed, guaranteed return; a SIP in equity funds can earn more over long periods but can also fall.
Can I close an RD early?
Banks allow it with a lower rate. A Post Office RD can be closed after 3 years.
