❓ Frequently Asked Questions
What is Fixed Deposit compounding? +
Compounding frequency determines how often interest is added to the principal. Monthly compounding gives higher returns than quarterly, which is better than annual.
Is FD interest taxable? +
Yes, in most countries FD interest is taxable as ordinary income. In India, TDS (Tax Deducted at Source) of 10% applies if annual interest exceeds ₹40,000.
What is the FD maturity formula? +
Maturity = P × (1 + r/n)^(n×t), where P = principal, r = annual rate, n = compounding periods/year, t = years.
Should I choose monthly or quarterly compounding? +
Monthly compounding gives slightly higher returns. For a ₹1 lakh deposit at 7% for 5 years, monthly compounding earns ~₹200 more than quarterly.
