Post Office FD (Time Deposit) Calculator 2026 – 100% Total Safety

Personalized FD Analysis

The Post Office Time Deposit (POTD) is one of India's safest investment avenues, backed directly by the Government of India. Unlike bank FDs where safety is capped at ₹5 Lakh (DICGC), Post Office deposits have 100% sovereign safety for the entire principal.

This calculator is specifically designed for the Post Office's unique interest payout system—where interest is calculated quarterly but paid out annually.

How Post Office TD Interest is Unique

While banks often reinvest interest quarterly, the Post Office TD system calculates it quarterly (compounding effect) but pays the accumulated interest back into your savings account every year on the anniversary of the deposit.

  • Tenure Buckets: Precisely 1, 2, 3, and 5 years. There are no intermediate tenures like '1 year 2 months'.
  • Tax Benefit: Only the **5-Year Time Deposit** qualifies for tax deduction under Section 80C. 1, 2, and 3-year TDs do not offer tax benefits.
  • Quarterly Compounding: Despite the annual payout, the interest rate is compounded quarterly, resulting in a higher 'Effective Annual Yield' than simple interest.
