Interest is the amount of money paid or earned for using an asset or engaging in a lending activity. It is typically calculated based on the principal amount (the original amount invested) and the interest rate.
Formula:
Simple Interest = Principal Amount x Interest Rate
Example:
If you invest $100 at an interest rate of 5%, the simple interest earned after 6 months is:
5
This means you earned $5 in interest over the 6 months.
Yearly Gain:
In addition to the simple interest, you may also earn or lose money due to interest earned or paid throughout the year. This can affect your overall gain or loss on an investment.
Formula for Yearly Gain:
Yearly Gain = Total Earnings - Total Expenses
Example:
You purchase a new laptop for $1500 and plan to use it for 5 years. The annual interest rate is 10%.
Total Earnings = $1500
Total Expenses = $100
Yearly Gain = 100 = $1400
Key points to remember:
Interest is typically paid or earned on a simple basis.
The interest rate is usually expressed as a decimal.
Interest can be added or subtracted from the principal amount to determine the final amount.
Understanding simple interest and yearly gain is crucial for managing finances and making informed financial decisions
