💵

Calculation Parameters

Specify your inputs below.

Calculated Result

Total Interest Earned $561.45
Maturity Value $10,561.45
💡

Expert Tip

Quarterly compounding is standard for FD investments in most banks, paying slightly higher yields than annual.

How this Calculator Works

This calculator computes interest returns on a bank Fixed Deposit (FD). By entering the deposit term, interest rate, and compounding interval, savers can determine the total payout received at maturity. Savers use it to compare low-risk term deposit offers.

Formula & Methodology

Maturity Amount = Principal * (1 + Interest Rate / n)^(n * t) Interest Earned = Maturity Amount - Principal - Principal is the initial deposit amount. - Interest Rate is the annual percentage rate (as a decimal). - n is the compounding periods per year (e.g. 4 for quarterly). - t is the total duration of the deposit in years.

Step-by-Step Calculation Example

Here is a step-by-step example showing how the calculations are performed:

You open a $10,000 fixed deposit with a 6% interest rate compounded quarterly (4 periods) for 3 years. 1. Calculate periodic rate: 0.06 / 4 = 0.015. 2. Calculate total periods: 4 * 3 years = 12. 3. Compute maturity amount: $10,000 * (1.015)^12 = $11,956.18. 4. Calculate interest: $11,956.18 - $10,000 = $1,956.18. Result: The fixed deposit will mature at $11,956.18, earning $1,956.18 in interest.

FAQ

How does compounding frequency impact investment returns?
More frequent compounding (e.g. monthly or daily vs. annually) generates higher effective annual yields (APY) because interest is calculated on accumulated interest earlier in the period.
What is the difference between Sharpe Ratio and Sortino Ratio?
The Sharpe ratio divides excess return by total standard deviation (both upside and downside volatility), whereas the Sortino ratio divides excess return by downside deviation only.
Should investment calculators replace professional wealth management?
No. Investment calculators model financial mathematics under assumed growth rates. Actual market performance fluctuates, so consult a licensed financial planner (CFP) or RIA for personalized advice.
