Frequently Asked Questions
How is FD interest calculated?+
FD interest is calculated using compound interest formula: A = P(1 + r/n)^(nt), where P is principal, r is annual rate, n is compounding frequency, and t is time.
What is the difference between simple and compound interest?+
Most FDs offer compound interest where interest earns interest. This results in higher returns compared to simple interest, especially for longer tenures.
How is tax calculated on FD interest?+
FD interest is added to your income and taxed as per your tax slab. TDS is deducted if interest exceeds ₹40,000 per year (₹50,000 for senior citizens).
Can I break my FD before maturity?+
Yes, but premature withdrawal usually attracts penalty of 0.5-1% on interest rate. Some banks don't allow premature withdrawal for very short-term FDs.
