How to Use This Calculator

Enter the following details to calculate your fixed deposit interest:

Principal amount: The initial deposit amount
Annual interest rate: The stated interest rate percentage
Term in years: The duration of the deposit
Compounding frequency: How often interest is calculated (annually, semi-annually, monthly, daily)

Click "Calculate" to see your total interest earned and the final amount. The calculator will also show you a growth chart.

How Fixed Deposit Interest Works

Fixed deposit interest is calculated using the compound interest formula:

A = P × (1 + r/n)^nt

Where:

A = Final amount
P = Principal amount
r = Annual interest rate (in decimal)
n = Number of times interest is compounded per year
t = Time the money is invested for (in years)

The interest earned is the difference between the final amount (A) and the principal amount (P).

Example Calculation

If you deposit $10,000 at 5% annual interest rate for 3 years with monthly compounding:

A = 10,000 × (1 + 0.05/12)^12×3 ≈ $11,616.50

Interest earned = $1,616.50

Factors Affecting Interest Rates

Several factors influence the interest rate you'll receive on a fixed deposit:

Deposit amount: Larger deposits may qualify for higher rates
Term length: Longer terms typically offer better rates
Bank reputation: Established banks often provide competitive rates
Economic conditions: Central bank policies affect interest rates
Your credit history: Some banks consider this when setting rates

Note: Interest rates can change frequently. Always check the latest rates before opening a fixed deposit account.
