About Post Office Time Deposit (TD / FD)
Post Office Time Deposit (TD) is similar to a Fixed Deposit (FD) at a bank but backed by the Government of India. You deposit a lump sum for a fixed tenure of 1, 2, 3, or 5 years and earn quarterly-compounded interest. The 5-year TD also qualifies for tax deductions under Section 80C.

| 2 Year TD | 7.0% p.a. (Quarterly Compounded) |

Interest Calculation Formula
Post Office TD uses Quarterly Compounding:
A = P × (1 + r/400)^(4 × t)
Where: P = Principal, r = Annual Rate %, t = Tenure in years
A = P × (1 + r/400)^(4 × t)
Where: P = Principal, r = Annual Rate %, t = Tenure in years
Key Features
- 80C Deduction: Only the 5-year TD qualifies for tax deduction under Section 80C.
- Premature Closure: Allowed after 6 months; penalty applies (lower interest rate).
- Auto-Renewal: Can be renewed at maturity for the same or different tenure.
- Multiple Accounts: No restriction on number of TD accounts per person.
- TDS: TDS applicable if interest exceeds ₹40,000/year (₹50,000 for seniors).
Example Calculation (₹1,00,000 — 5 Years at 7.5%)

| Rate | 7.5% p.a. (Compounded Quarterly) |
