How this calculator works
Each monthly instalment earns interest, compounded quarterly, for the time it stays in the account: maturity = Σ R × (1 + r/4)k/3 for k = 1 to n months. This is the method banks and India Post use, and it matches India Post’s published maturity values to within ₹1–2 (India Post rounds each quarter slightly differently).
The post office 5-year RD pays 6.7% for October–December 2026. Bank RD rates usually match the bank’s FD rate for the same tenure.
Worked example: ₹5,000 a month for 5 years at 6.7%
| Item | Amount |
|---|---|
| Total deposited | ₹3,00,000 |
| Interest earned | ₹56,829 |
| Maturity value | ₹3,56,829 |

Frequently Asked Questions
What is the post office RD rate now?
6.7% a year for the 5-year post office RD in October–December 2026, compounded quarterly.
Is RD interest taxable?
Yes, at your slab rate. RD interest is added to FD interest at the same bank when checking the ₹50,000 TDS threshold (₹1 lakh for seniors).
What happens if I miss an RD instalment?
Banks and India Post charge a small penalty for late instalments, and several missed instalments can lead to the account being closed early.
RD or SIP?
An RD gives a fixed, guaranteed return; an equity SIP can return more over long periods but can also fall. Many people use RDs for goals within 1–3 years.
