What is a Fixed Deposit?
A Fixed Deposit (FD) is a savings instrument offered by banks and NBFCs that pays a higher interest rate than a regular savings account in exchange for locking your money in for a fixed tenure.
FDs are considered one of the safest investment options in India. Returns are guaranteed at the booked rate, and the principal is protected — bank deposits are insured up to ₹5 lakh per depositor under DICGC.
How to Use
- Enter the principal amount you want to deposit in rupees.
- Set the annual interest rate (typical FD: 6–8%).
- Choose the tenure in years.
- Pick the compounding frequency (monthly gives the highest maturity).
Formula Used
The calculator uses the compound interest formula:

Frequently asked questions.
What is a Fixed Deposit?
A Fixed Deposit (FD) is a financial instrument from banks or NBFCs that pays a higher interest rate than a regular savings account, with a fixed tenure and guaranteed returns.
How is FD interest calculated?
FD interest is calculated using compound interest: A = P × (1 + r/n)^(n×t), where P is the principal, r is the annual rate, n is the compounding frequency, and t is the tenure in years.
Is this FD calculator free to use?
Yes, Binary Lab's FD calculator is completely free with no signup required.
Can FDs be withdrawn before maturity?
Yes, but most banks charge a premature-withdrawal penalty (typically 0.5% to 1% lower than the booked rate). Tax-saver FDs have a 5-year lock-in.
Is TDS applicable on FD interest?
Yes. TDS applies if the interest earned across all FDs in a bank exceeds ₹40,000 (₹50,000 for senior citizens) in a year. Submit Form 15G/15H if your income is below the taxable limit.
