What is a Post Office Savings Account?

The most basic India Post savings product — works much like a bank savings account. Interest is calculated on the balance and credited once a year, then itself starts earning interest the following year. There is no fixed maturity date, since it’s a running account, not a term deposit — so "years" here is just how far ahead you want to see the balance projected, not a scheme-imposed term.

What this simplifies

Real accounts calculate interest on the minimum balance between the 10th and last day of each month, not a flat annual figure on the opening balance — if you make withdrawals or deposits during the year, your real interest will differ from this projection. This calculator assumes the balance sits untouched for the whole period.
