FD Calculator
A Fixed Deposit (FD) calculator helps you estimate the maturity value of your FD investment and the interest you will earn over the deposit period. A Fixed Deposit is one of the safest and most popular investment options in India, offered by banks and post offices, where you deposit a lump sum amount for a fixed period and earn a guaranteed interest rate. Unlike mutual funds or stocks, the returns on an FD are guaranteed and not affected by market fluctuations, making it ideal for conservative investors and for parking emergency funds. This calculator takes four inputs: the deposit amount, the annual interest rate, the deposit period in years, and the compounding frequency (typically quarterly for bank FDs in India). It then shows the maturity value (your deposit plus interest) and the total interest earned. FD interest rates in India typically range from 5% to 8% for the general public, with senior citizens getting an extra 0.25% to 0.50%. Note that FD interest is taxable, and TDS is deducted if the interest exceeds Rs 40,000 in a financial year.
Formula
A = P x (1 + r/n)^(n x t) Where: A = Maturity amount (principal + interest) P = Principal (deposit amount) r = Annual interest rate (as a decimal) n = Compounding frequency per year t = Time in years
Example
Example: Deposit Rs 1,00,000 at 6.5% annual interest for 5 years, compounded quarterly (n = 4). Step 1: Identify the values P = 1,00,000 r = 6.5 / 100 = 0.065 n = 4 (quarterly) t = 5 years Step 2: Apply the formula A = 1,00,000 x (1 + 0.065/4)^(4x5) A = 1,00,000 x (1.01625)^20 A = Rs 1,38,042 (approx) Step 3: Interest earned = 1,38,042 - 1,00,000 = Rs 38,042 Result: Your Rs 1 lakh FD grows to about Rs 1.38 lakh in 5 years, earning Rs 38,042 in interest.

Frequently Asked Questions
What is a Fixed Deposit (FD)?
A Fixed Deposit is a financial instrument provided by banks and post offices where you deposit a lump sum amount for a fixed period, ranging from 7 days to 10 years, and earn a guaranteed interest rate. The interest rate is fixed at the time of deposit and does not change during the tenure, regardless of market conditions.
How is FD interest calculated?
FD interest is calculated using the compound interest formula: A = P x (1 + r/n)^(n x t), where P is the deposit amount, r is the annual interest rate, n is the compounding frequency (usually quarterly for bank FDs in India), and t is the time in years. The interest is compounded and added to the principal at regular intervals.
What is the typical interest rate for bank FDs in India?
Bank FD interest rates in India typically range from 5% to 8% for the general public, depending on the bank and the tenure. Senior citizens usually get an additional 0.25% to 0.50%. Small finance banks and post offices sometimes offer slightly higher rates than large commercial banks. Always compare rates across banks before investing.
Is FD interest taxable?
Yes, FD interest is fully taxable as per your income tax slab. The interest is added to your total income and taxed at your applicable rate. Additionally, if the total interest from all your FDs in a financial year exceeds Rs 40,000 (Rs 50,000 for senior citizens), the bank deducts 10% TDS. If your total income is below the taxable limit, you can submit Form 15G or 15H to avoid TDS.
Can I withdraw my FD before maturity?
Yes, most banks allow premature withdrawal of FDs, but you will pay a penalty, typically 0.5% to 1% of the interest rate. The interest will be recalculated at the rate applicable for the period the money was actually deposited, minus the penalty. Some banks also offer sweep-in FDs that allow partial withdrawals without breaking the entire deposit.
What is the difference between FD and RD?
In a Fixed Deposit (FD), you invest a lump sum amount once and earn interest on it. In a Recurring Deposit (RD), you invest a fixed amount every month for a set period. Both offer guaranteed returns, but FD is better if you have a lump sum to invest, while RD is better if you want to save gradually from your monthly income.
