Post Office TD Calculator
Compute your Post Office Time Deposit maturity — pick a 1, 2, 3 or 5-year tenure and the official GoI rate applies automatically with quarterly compounding.
Year-wise growth
| Year | Deposited | Value at year end |
|---|---|---|
| 1 | ₹1,00,000 | ₹1,07,714 |
| 2 | ₹1,00,000 | ₹1,16,022 |
| 3 | ₹1,00,000 | ₹1,24,972 |
| 4 | ₹1,00,000 | ₹1,34,611 |
| 5 | ₹1,00,000 | ₹1,44,995 |
What is a Post Office time deposit?
The Post Office Time Deposit (TD) is India Post's fixed deposit: a one-time deposit for 1, 2, 3 or 5 years, backed directly by the Government of India. Each tenure carries its own GoI-notified rate — currently 6.9% for 1 year up to 7.5% for 5 years — revised quarterly for new deposits but locked for the life of yours once booked.
Pick a tenure in this calculator and the official rate for that tenure is applied automatically — you never have to look it up. The result shows the rate applied, interest earned, the maturity value and year-wise growth, all on the quarterly-compounding basis India Post itself uses.
The TD maturity formula
A = P × (1 + r ÷ 4)^(4 × t)
- A — the maturity value
- P — the amount you deposit
- r — the tenure-wise GoI rate as a decimal (7.5% = 0.075 for the 5-year slab)
- t — the tenure you picked: 1, 2, 3 or 5 years
Interest compounds quarterly. The published India Post maturity values follow the same convention, so the calculator's figure should match your deposit receipt.
How to use this calculator
- Enter the deposit amount — ₹1,000 upwards, no upper limit.
- Pick the tenure: 1 year (6.9%), 2 years (7.0%), 3 years (7.1%) or 5 years (7.5%). The matching rate is applied automatically — these are the currently notified rates, revised quarterly by the Government of India.
- Read the results: the rate applied, invested amount, interest earned and the maturity value, plus year-wise growth.
A worked example
₹1,00,000 in the 5-year TD at 7.5% p.a.:
- Invested amount: ₹1,00,000
- Interest earned: ₹44,994.80
- Maturity value: ₹1,44,994.80
The deposit is worth ₹1,07,713.59 after year one and ₹1,24,971.64 by year three. A larger example on the 3-year slab: ₹5,00,000 at 7.1% matures to ₹6,17,537.50.
₹1,00,000 across the four TD tenures
| Tenure | Rate (p.a.) | Maturity value | Interest earned |
|---|---|---|---|
| 1 year | 6.9% | ₹1,07,080.60 | ₹7,080.60 |
| 2 years | 7.0% | ₹1,14,888.18 | ₹14,888.18 |
| 3 years | 7.1% | ₹1,23,507.50 | ₹23,507.50 |
| 5 years | 7.5% | ₹1,44,994.80 | ₹44,994.80 |
Rates as currently notified for the quarter; the Government of India revises them quarterly for new deposits. Quarterly compounding throughout.
Only the 5-year TD does — deposits up to ₹1.5 lakh a year, and only if you file under the old regime. The 1, 2 and 3-year tenures carry no 80C benefit. The interest is taxable for every tenure.
Yes, at your slab rate under income from other sources. Interest is calculated quarterly and credited annually, and it is cleanest to report it on an accrual basis each year. Under the new regime for FY 2025-26, the 87A rebate keeps total income up to ₹12 lakh tax-free — reporting is still required.
No. The tenure-wise rate in force on the day you book is contractual for the full term. Quarterly revisions apply only to deposits opened after the revision.
Not within the first six months. Between six months and a year you get only the Post Office savings-account rate; after a year the interest is recalculated at a reduced rate below the booked slab. Match the tenure to when you will actually need the money.
The TD carries a direct sovereign guarantee with no upper limit, while bank deposits are insured up to ₹5 lakh per bank under DICGC. When the TD rate matches or beats your bank's FD card — as the 7.5% 5-year slab often does — the TD is the more conservative choice at equal or better yield.
