Fixed Deposit — Key Facts for Indian Investors
FD Formula: Maturity = P × (1 + r/n)^(n×t) where P = Principal, r = annual rate, n = compounding frequency per year, t = time in years.
Tax on FD Interest: FD interest is fully taxable as per your income tax slab. Banks deduct TDS at 10% if interest exceeds ₹40,000/year (₹50,000 for senior citizens). If your total income is below taxable limit, submit Form 15G/15H to avoid TDS.
Senior Citizen FDs: Banks offer 0.25% to 0.75% extra interest for senior citizens (age 60+). Always check the senior citizen rate separately.
Best FD rates: Small Finance Banks and NBFCs often offer higher rates (8-9%+) but have lower DICGC insurance limit than scheduled commercial banks. DICGC insures up to ₹5 lakh per bank.
