Calculate your Fixed Deposit returns instantly. Enter your deposit amount, interest rate, and tenure to see how much your FD will grow with compound interest.
An FD (Fixed Deposit) calculator is a free online financial tool that helps you estimate the maturity amount and total interest earned on your fixed deposit investment. It allows you to plan your investments by showing you exactly how much your money will grow over a specific period at a given interest rate.
Fixed Deposits are one of the most popular and safest investment options in India. They offer guaranteed returns at a predetermined interest rate for a fixed tenure. An FD calculator simplifies the complex mathematical calculations involved in determining the maturity amount, especially when compound interest is applied at different frequencies.
How Does an FD Calculator Work?
The FD calculator uses a compound interest formula to compute the maturity amount based on the variables you enter. It takes four key inputs:
Principal Amount (P) — The initial amount you deposit
Interest Rate (r) — The annual interest rate offered by the bank
Tenure (t) — The duration for which you want to invest
Compounding Frequency (n) — How often the interest is compounded (monthly, quarterly, half-yearly, or yearly)
The calculator instantly processes these inputs and displays the total maturity amount, the interest earned, and a visual breakdown of your investment vs. returns through a donut chart.
Formula to Calculate FD Maturity
The maturity amount of a fixed deposit with compound interest is calculated using the following formula:
A = P × (1 + r/n)(n × t)
Where:
A = Maturity amount (principal + interest)
P = Principal amount (initial deposit)
r = Annual interest rate (in decimal form, e.g., 8.10% = 0.081)
n = Number of times interest is compounded per year
t = Time period in years
Example Calculation
Suppose you invest ₹1,00,000 at 8.10% p.a. compounded quarterly for 5 years:
P = ₹1,00,000
r = 0.081
n = 4 (quarterly)
t = 5 years
A = 1,00,000 × (1 + 0.081/4)(4 × 5)
A = 1,00,000 × (1.02025)20
A = ₹1,49,014 (approximately)
Therefore, you would earn approximately ₹49,014 as interest on your fixed deposit.

Frequently Asked Questions
A Fixed Deposit (FD) is a financial instrument offered by banks and NBFCs where you deposit a lump sum for a fixed tenure at a predetermined interest rate. The interest is compounded and paid at maturity or at regular intervals. FDs are considered one of the safest investment options in India.
FD interest is calculated using the compound interest formula: 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. Most banks compound interest quarterly.
Yes, interest earned on Fixed Deposits is taxable under "Income from Other Sources." If the total FD interest earned in a financial year exceeds ₹40,000 (₹50,000 for senior citizens), TDS at 10% is deducted by the bank. You can submit Form 15G/15H to avoid TDS if your total income is below the taxable limit.
There is no upper limit on the amount you can invest in a fixed deposit. However, deposits up to ₹5 lakh per bank are insured by DICGC. For amounts above ₹5 lakh, you may consider spreading across multiple banks for insurance coverage.
Yes, most banks allow premature withdrawal of FDs, but a penalty of 0.5% to 1% is usually charged on the applicable interest rate. Some banks also offer a partial withdrawal facility. Check with your bank for specific terms.
In a cumulative FD, the interest is compounded and paid at maturity along with the principal, resulting in higher effective returns. In a non-cumulative FD, interest is paid out at regular intervals (monthly, quarterly, or annually), which is suitable for those seeking regular income.
