Detailed Formula Explanation

The compound interest formula, A = P (1 + r/n)^nt, might seem complex, but it’s a powerful tool. Let’s break it down. ‘P’ is your starting principal. The part in the parenthesis, (1 + r/n), calculates the growth factor for a single compounding period. ‘r/n’ divides the annual rate by the number of times it’s compounded. This factor is then raised to the power of ‘nt’—the total number of compounding periods over the entire investment tenure. This exponentiation is what creates the “compounding” effect, where your interest starts earning its own interest, leading to exponential growth over time.

2. How to Use

Using our Term Deposit Calculator is a simple, four-step process:

1. Enter Your Investment Details: Start by selecting your preferred currency. Then, fill in the primary fields: the ‘Principal Investment Amount’ (your initial deposit), the ‘Annual Interest Rate’ offered by your bank, and the ‘Investment Tenure’ (how long you plan to invest, in years or months).
2. Set Compounding Frequency: From the dropdown menu, choose how often the interest is compounded. This could be annually, half-yearly, quarterly, or monthly. More frequent compounding generally leads to higher returns.
3. Calculate and See Results: Click the ‘Calculate’ button. The tool will instantly display a summary on the right, showing your initial principal, total interest earned, and the final maturity amount.
4. Explore Visualizations: Scroll down to explore the interactive charts that break down your investment’s growth. You can also view a detailed year-by-year or month-by-month breakdown in the Amortization Schedule. Use the ‘Reset’ button to clear the fields and start a new calculation.

Seeing the year-on-year growth in a bar chart or the compounding curve in a line chart can be a powerful motivator to save and invest wisely. It helps you compare different investment scenarios quickly—what if the interest rate was 0.5% higher? What if you invested for two more years? You can get answers in seconds. This tool is perfect for financial planning, educating yourself about the power of compounding, or simply verifying the returns quoted by a financial institution. We prioritize accuracy, user experience, and data visualization to give you a powerful free resource for your financial toolkit.

5. FAQs

What is a term deposit?

A term deposit, often called a fixed deposit (FD), is a type of savings account where you deposit a lump sum of money for a fixed period (tenure) at a predetermined interest rate. The interest rate is typically higher than a regular savings account, but you cannot withdraw the money before the tenure ends without incurring a penalty.

What does ‘compounding frequency’ mean?

Compounding frequency is how often the interest earned is calculated and added to your principal amount. The new, larger principal then earns interest in the next period. More frequent compounding (e.g., monthly) results in slightly higher returns than less frequent compounding (e.g., annually) for the same annual interest rate.

Can I use this calculator for recurring deposits?

No, this calculator is specifically designed for lump-sum term deposits where you invest a single amount at the beginning. A recurring deposit (RD) involves making regular periodic investments, which requires a different calculation formula.

Is the calculated maturity amount guaranteed?

The calculation is based on the inputs you provide. If the interest rate is fixed for the entire tenure of your term deposit, then the maturity amount calculated by our tool will be accurate. However, if the interest rate is variable, the actual return may differ.

How does the tenure type (years/months) affect the calculation?

The calculator internally converts the tenure into years to use in the standard formula. For example, a tenure of 24 months is treated as 2 years. This ensures consistency and accuracy in applying the annual interest rate and compounding frequency over the investment period.
