n

Example Calculation
Let's calculate manually: ₹1,00,000 at 7% interest for 5 years with quarterly compounding.
P = 100000
r = 7% = 0.07
n = 4 (quarterly)
t = 5 years
A = 100000 × (1 + 0.07/4)^(4×5)
= 100000 × (1.0175)^20
= 100000 × 1.41478
= ₹1,41,478

Frequently Asked Questions
Get answers to common questions about Fixed Deposits.
How is FD interest calculated?
FD interest is calculated using compound interest formula: A = P(1 + r/n)^(nt).
Where P = principal, r = annual interest rate, n = compounding frequency, t = time in years.
Most banks compound quarterly.
What is the difference between FD and RD?
FD (Fixed Deposit) is a lump sum investment for fixed period. RD (Recurring Deposit) is monthly
installment investment. FD gives higher returns for same amount, but RD helps in disciplined
monthly savings.
Is TDS deducted on FD interest?
Yes, banks deduct 10% TDS if interest exceeds ₹40,000 (₹50,000 for senior citizens) in a financial
year. You can submit Form 15G/15H to avoid TDS if total income is below taxable limit.
Can I break my FD before maturity?
Yes, but with penalty. Banks charge 0.5-1% lower interest rate than contracted rate.
Some banks offer loan against FD as better alternative to breaking FD.
What is tax saving FD under Section 80C?
Tax saving FD has 5-year lock-in period. Investment up to ₹1.5 lakh qualifies for deduction
