The Basics of Simple Interest
Simple interest is a quick and easy method of calculating the interest charge on a loan or investment. It is determined by multiplying the principal amount by the interest rate and the number of periods. Unlike compound interest, simple interest is only calculated on the principal amount of a loan or deposit.
Formula:
Simple Interest = Principal × Interest Rate × Time
- Principal: The initial amount of money borrowed or invested.
- Interest Rate: The percentage charged or paid for the use of money, usually expressed annually.
- Time: The duration for which the money is borrowed or invested, typically in years.
This calculator is ideal for understanding the basic growth of a single deposit in a savings account or a simple loan where interest doesn't compound. It provides a clear picture of how much pure interest is generated over a specified period.
Simple vs. Compound Interest:
It's important to distinguish simple interest from compound interest. Compound interest is calculated on the initial principal and also on all of the accumulated interest from previous periods. This means your money grows much faster with compounding, as you earn interest on your interest. Most real-world investments and loans use compound interest.
Important Note
This calculator provides a simplified view for educational purposes. Most savings accounts and investments use compound interest, which would result in a higher final balance. For more accurate projections, consider a compound interest calculator.
