Fixed Deposit (FD) Calculator

As of late 2025, the fixed deposit market in India has continued to grow, with total bank deposits exceeding ₹253 lakh crore by December 31, 2025. This reflects a strong preference among investors for capital safety and predictable returns, especially in uncertain market conditions.

In 2026, banks offering competitive FD interest rates, with small finance banks offering up to 8%–8.6% p.a., while public and private sector banks generally range between 6% and 7.5%.

A fixed deposit calculator helps you estimate the maturity value of your investment, compare FD options across tenures and rates, and plan your savings before locking in your funds.

How Does a Fixed Deposit Calculator Work?

A fixed deposit calculator estimates the maturity value of your FD based on a few key inputs: the deposit amount, interest rate, tenure, and compounding frequency.

Once you enter these details, the calculator applies a standard interest calculation method to show:

• Total interest earned
• Maturity amount at the end of the tenure

For cumulative FDs, interest is compounded periodically and paid at maturity.

For non-cumulative FDs, interest payouts are calculated based on the selected payout frequency.

Fixed Deposit Interest Calculation Formula

The maturity value of a fixed deposit depends on whether the FD is cumulative or non-cumulative.

Most FD calculators use compound interest for cumulative FDs.

Maturity Amount = P × (1 + r / n)^n × t

Where:

• P = Principal
• r = Annual interest rate
• n = Number of times interest is compounded in a year
• t = Deposit tenure

Example

Assume the following:

• Deposit amount: ₹2,00,000
• Interest rate: 7% per annum
• Tenure: 3 years
• Compounding frequency: Quarterly (n = 4)

Step 1: Apply the formula

Maturity Amount = 2,00,000 × (1 + 0.07 / 4)^{4 × 3}

Step 2: Result

• Maturity amount: ~₹2,45,900
• Total interest earned: ~₹45,900

This means your ₹2 lakh fixed deposit could grow to approximately ₹2.46 lakh after 3 years at 7% interest, assuming quarterly compounding.

Note: The above calculation is only an illustrative example. Actual fixed deposit interest rates may vary across banks and may differ based on the depositor’s age group, such as regular or senior citizen categories.

What are the Types of Fixed Deposits

Fixed deposits are broadly classified by how interest is paid.

1. Cumulative Fixed Deposit

• Interest is reinvested and compounded
• Interest payout happens at maturity
• Suitable for long-term savings goals
• Results in a higher maturity amount due to compounding

2. Non-Cumulative Fixed Deposit

• Interest is paid out periodically (monthly, quarterly, half-yearly, or annually)
• Suitable for investors seeking regular income
• Maturity amount includes only the principal, as interest is paid separately

A fixed deposit calculator helps you estimate returns for both types by adjusting the tenure, interest rate, and compounding or payout frequency.
