Maturity value, annual interest payout and tax notes for 1, 2, 3 and 5 year Post Office Time Deposit accounts.
The Post Office Time Deposit Calculator projects a National Savings Time Deposit account over its 1, 2, 3 or 5 year tenure, applying the scheme's actual mechanics: interest is compounded quarterly but paid out annually, so the calculator reports the effective annual yield, the yearly payout, the year-by-year schedule and what the same money would have become had every payout been re-deposited. It also flags the ₹1,000 minimum, the ₹100 multiple rule, the section 80C position and the TDS threshold. It is for savers choosing a tenure, and is informational rather than tax advice.
Open Post Office Time Deposit Calculator on AltFTool — it loads instantly in your browser.
Enter the deposit amount in rupees and pick a tenure of 1, 2, 3 or 5 years; the interest rate field fills with that tenure's notified rate and stays editable.
Choose your income-tax slab rate and tick Senior citizen (higher TDS threshold) to apply the right section 194A limit.
Read the interest paid each year, the effective annual yield after quarterly compounding, the year-by-year payout table and the early-closure payout, then press Copy result.
Most calculators quietly compound the interest for the full term; this one pays it out annually as the scheme actually does, and shows the reinvested figure separately for comparison.
It encodes the real penalty ladder — nothing before six months, savings-account rate between six and twelve months, and a 2 percentage point cut thereafter.
Amounts below the ₹1,000 minimum or off the ₹100 multiple are flagged, so the plan you build is one a post office would actually open.
Accounts run for 1, 2, 3 or 5 years, and the calculator uses notified rates of 6.9%, 7.0%, 7.1% and 7.5% respectively. Small-savings rates are re-notified every quarter by the Ministry of Finance, so check the rate in force for your quarter and override the field if it has changed.
Both, in a sense: interest is calculated on quarterly compounding but is payable annually and credited to your post office savings account. That is why a 5-year deposit does not grow to the same figure as a five-year quarterly-compounded FD unless you re-deposit every payout yourself.
Only the 5-year account. The deduction is capped at ₹1.5 lakh, and that ceiling is shared across all your 80C items, so an existing PPF or insurance premium eats into it. The 1, 2 and 3 year tenures carry no 80C benefit.
TDS at 10% applies once annual interest crosses ₹50,000, or ₹1,00,000 for senior citizens, where your PAN is on record. TDS is not the final tax — the interest is still taxable at your slab rate, so confirm your own position with a tax professional.
