What is a Simple and Compound Interest Calculator?
A simple and compound interest calculator is an online tool that calculates the interest earned on an investment or loan. Simple interest is calculated on the initial principal, while compound interest accounts for interest on both the principal and accumulated interest. This calculator lets you switch between the two methods and see the difference in returns.
For example, if you invest ₹5,00,000 at a 10% annual interest rate for 5 years, the calculator will show you the returns for both simple and compound interest, helping you decide which investment suits your goals.
How Does a Simple and Compound Interest Calculator Work?
The simple and compound interest calculator uses two formulas:
- Simple Interest (SI):
SI = P * R * T- P: Principal amount
- R: Annual interest rate (as a decimal)
- T: Time period in years
- Compound Interest (CI):
A = P * (1 + R/n)^(n*T), Interest =A - P- A: Total amount
- n: Compounding frequency per year (e.g., 12 for monthly)
Here’s how to use it:
- Enter the Principal Amount (e.g., ₹5,00,000).
- Input the Interest Rate (e.g., 10% p.a.).
- Select the Time Period in months (e.g., 60 months).
- Choose Simple or Compound Interest and, for compound, select the compounding frequency.
- View the Total Interest and Total Amount instantly.

Factors Affecting Interest Calculations
Several factors influence the results of a simple and compound interest calculator:
| Factor | Description | Impact on Interest |
|---|---|---|
| Principal Amount | The initial investment (₹1,000 to ₹100 crore). | Higher principal = Higher interest |
| Interest Rate | The annual rate (1% to 20%). | Higher rate = Higher interest |
| Time Period | Duration in months (1 to 360 months). | Longer period = Higher interest |
| Compounding Frequency | How often interest is compounded (e.g., monthly, annually). | More frequent compounding = Higher returns |
- Example: For ₹5,00,000 at 10% for 5 years, monthly compounding yields ₹3,23,848 in interest, while annual compounding yields ₹3,05,255.
