Types of Interest Explained
Simple Interest
Simple interest is the easiest type to understand. It only grows on your original money. If you put $100 in a bank at 5% simple interest, you get $5 every year. That's it.
The formula is very simple: Interest = Money × Rate × Time. So $100 × 5% × 3 years = $15 total interest.
Simple interest is good for short-term loans or basic savings accounts. It's easy to calculate and understand.
Many personal loans use simple interest. Car loans sometimes use it too. It's straightforward and predictable.
Compound Interest
Compound interest is more powerful. It grows on your original money PLUS all the interest you already earned. This makes your money grow faster over time.
With compound interest, your $100 at 5% becomes $105 after one year. In year two, you earn 5% on $105, not just $100. This creates a snowball effect.
Compound interest is great for long-term savings and investments. The longer you wait, the more money you make.
Most savings accounts use compound interest. Investment accounts use it too. It helps your money grow much faster than simple interest.
Loan Payments
When you borrow money, you need to pay it back with interest. Our calculator helps you find your monthly payment amount. This is useful for car loans, home loans, and personal loans.
The calculator considers your loan amount, interest rate, and how long you want to take to pay it back. It then tells you exactly how much to pay each month.
Knowing your monthly payment helps you budget better. You can compare different loans and pick the best one for your situation.
Use the loan calculator before you borrow money. It shows you the total cost. You can see how much interest you will pay over time.
