Fixed Deposit Calculator

How Is Fixed Deposit Interest Calculated?

A fixed deposit allows you to place a lump sum of money with a bank or financial institution for a selected period at a specified interest rate. Depending on the product, interest may be compounded at regular intervals or paid according to the selected deposit terms.

For a cumulative fixed deposit, the estimated maturity value can be calculated using the principal amount, annual interest rate, compounding frequency, and investment tenure.

The basic compound interest calculation used for an estimate is based on the relationship between the principal, interest rate, number of compounding periods, and time.

Deposit Amount

The deposit amount is the initial lump sum placed into the fixed deposit. This amount forms the starting principal for the calculation.

Annual Interest Rate

The annual interest rate represents the yearly interest rate assumed for the fixed deposit. Enter the rate offered or expected for your selected deposit product.

Investment Tenure

The investment tenure is the length of time your money remains invested. You can enter the tenure in years or months.

Compounding Frequency

Compounding frequency determines how often interest is mathematically added to the deposit balance for the estimate. This calculator supports monthly, quarterly, half-yearly, and yearly compounding assumptions.

Banks and financial institutions may use their own interest calculation methods and product-specific rules. Always check the official terms of your fixed deposit before making financial decisions.

Understanding Fixed Deposits

Fixed deposits are commonly used by savers who want to keep money invested for a predetermined period while earning interest according to the terms of the deposit.

In India, banks and financial institutions may offer different fixed deposit interest rates depending on the institution, deposit tenure, customer category, and other conditions.

Cumulative Fixed Deposits

In a cumulative fixed deposit, interest is generally accumulated during the deposit tenure and paid together with the principal at maturity. This can allow the interest to contribute to future interest calculations depending on the institution's compounding method.

Non-Cumulative Fixed Deposits

Non-cumulative fixed deposits generally pay interest at regular intervals, such as monthly, quarterly, half-yearly, or yearly, depending on the product terms.

The calculator on this page is designed primarily as a mathematical estimate for a cumulative-style fixed deposit calculation. It does not model every bank's individual payout structure.
