How it works
Formula: Maturity = P × (1 + r/n)ⁿᵗ
Example: ₹1 lakh at 7.25% for 3 years, quarterly compounding → 1,00,000 × (1 + 0.0725/4)¹² = ₹1,24,042 (interest ₹24,042).
FAQs
What formula does the FD calculator use?
Maturity = P × (1 + r/n)^(n×t), where P = principal, r = annual rate, n = compounding periods per year, t = years.
Which compounding frequency is best?
Most Indian banks compound quarterly on regular FDs. Monthly compounding gives marginally higher maturity (typically 10–30 bps extra APY). Always compare the effective annualised yield, not just the advertised rate.
Is FD interest taxed?
Yes, at your slab rate. Banks deduct 10% TDS if total interest from one bank exceeds ₹40,000 in a year (₹50,000 for senior citizens). Submit Form 15G/15H if below taxable income.
Premature withdrawal penalty?
Most banks charge 0.5–1% of the applicable rate if you close before maturity. The actual interest paid is the lower of (contracted rate – penalty) or (card rate for the actual duration – penalty).
