How is FD interest calculated?

For cumulative FDs: Maturity = P × (1 + r/n)^(n×t) with quarterly compounding (n=4). For non-cumulative, interest is paid out monthly/quarterly without reinvestment.

Are FD returns taxable?

Yes. FD interest is added to your income and taxed at your slab rate. TDS at 10% is deducted if interest exceeds ₹40,000 per year (₹50,000 for seniors).

Which is better — FD or RD?

FD if you have a lumpsum; RD if you want to save monthly. For long-term wealth, equity funds typically outperform both.

How is FD maturity calculated?

Fixed Deposit maturity uses compound interest: M = P × (1 + r/n)^n×t, where P is principal, r is annual rate, n is compounding frequency per year, and t is tenure in years. Most Indian banks compound quarterly.

Tax on FD interest

FD interest is fully taxable as per your slab. Banks deduct 10% TDS if interest exceeds ₹40,000/year (₹50,000 for seniors). Submit Form 15G/15H if income is below the taxable limit.
