Simple Interest vs. Compound Interest
There are two primary methods used in any interest rate calculator:
Simple Interest
Simple interest is calculated only on the principal amount. It is commonly used in short-term loans and basic financial calculations.
Compound Interest
Compound interest is calculated on the principal plus accumulated interest. This method is widely used in savings accounts, fixed deposits, and long-term investments.
Example: Simple vs Compound Interest
Let’s understand this with a quick example using a financial calculator online:
| Type | Principal | Rate | Time | Total Amount |
|---|---|---|---|---|
| Simple Interest | ₹10,000 | 10% | 2 Years | ₹12,000 |
| Compound Interest | ₹10,000 | 10% | 2 Years | ₹12,100 |
As you can see, compound interest gives higher returns due to the power of compounding.
The Impact of Compounding Frequency
In a compound interest calculator, the frequency of compounding plays a major role. The more frequently interest is added, the higher your returns.
Yearly (Annually)
Interest is added once per year.
Half-Yearly
Interest is added twice a year, increasing returns slightly.
Quarterly / Monthly
Interest is added frequently, making it ideal for FD and RD investments.
