This account has no lock-in, no maturity date, and no tenure to choose — money simply sits there and earns a small interest every year, exactly like a bank savings account. What thiha hus calculator actually helps you figure out is how much of that yearly interest you get to keep tax-free.
This is an interest estimate, not an account statement. Real interest is worked out month by month on your lowest balance between the 10th and the last day of that month, then credited once a year — so if your balance moves around a lot during the year, your actual interest will differ slightly from this flat estimate.
An Account, Not an Investment
It helps to think of this less as a savings scheme and more as the post office’s answer to a bank savings account. There’s no term to lock into, nothing matures, and you can walk in and withdraw whenever you like, subject to keeping the account active. The only real decision to make here is how much idle cash to park in it, since the return — 4% a year — is modest by design.
Where the Tax-Free Deduction Comes From
Section 80TTA lets anyone below 60 exclude up to Rs 10,000 of savings account interest from their taxable income every year. Senior citizens get a much larger version of this under Section 80TTB, covering up to Rs 50,000 of interest from savings and deposit accounts combined. Both of these deductions apply only if you file your return under the old tax regime — switch to the new regime, and neither is available, meaning every rupee of interest becomes fully taxable at your slab rate.
| Your Situation | Tax-Free Limit on Interest |
|---|---|
| Below 60, Old Regime | Rs 10,000 (Section 80TTA) |
| 60 or above, Old Regime | Rs 50,000 (Section 80TTB) |
| Any age, New Regime | None — fully taxable |
Using This Calculator
Enter the balance you typically keep sitting in the account, tick the tax regime you file under, and mark the senior citizen box if it applies to you. You’ll see your estimated annual interest, split into what stays tax-free and what gets added to your taxable income. Since the post office does not deduct any TDS on this interest, the taxable portion shown here is something you need to declare and pay tax on yourself when filing your return — it will not show up automatically.
What Else the Account Offers
Beyond the interest, a Post Office Savings Account comes with a cheque book, a debit card with a daily ATM withdrawal cap of Rs 25,000, and internet and mobile banking through India Post Payments Bank. You need at least one transaction every three years to keep the account from going dormant. It can be opened solo, jointly with up to two other adults, or on behalf of a minor — and a minor above 10 can run the account entirely on their own.
