Frequently Asked Questions
What is the FD formula?
FD Maturity = 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.
Which compounding frequency gives the highest FD returns?
Monthly compounding gives the highest effective yield, followed by quarterly, half-yearly, and annual. The difference is small for short tenures.
Is FD interest taxable?
Yes. FD interest is added to your income and taxed at your slab rate. TDS at 10% is deducted if total interest exceeds ₹40,000 per year (₹50,000 for seniors).
