Frequently asked questions
How is FD interest calculated?
Banks compound quarterly by convention, so a 7% FD adds 1.75% to the balance every three months rather than 7% once a year. That is why the maturity value is higher than principal × rate × years, and why the effective yield slightly exceeds the quoted rate.
Is FD interest taxable?
Yes, at your slab rate, and it is taxed in the year it accrues rather than when the deposit matures. The bank deducts TDS at 10% above ₹40,000 of interest a year (₹50,000 for senior citizens), but if you are in a higher slab you owe the difference at filing.
What happens if I break an FD early?
You get the rate applicable to the period actually completed, not the rate you booked, and most banks apply a penalty of 0.5–1% on top. Breaking a five-year FD after one year can mean earning less than a savings account would have paid.
Is an FD a good investment?
It is a safe one, not a high-returning one. At 7% before tax and 4.9% after tax in the 30% slab, against 6% inflation, an FD is roughly preserving purchasing power rather than growing it. It suits money you cannot afford to see fall — an emergency fund, a near-term goal — rather than long-term wealth building.
